Answer:
x=−7/5and y=−6/5
Step-by-step explanation:
Step: Substitute−2x−4foryiny=3x+3:
y=3x+3
−2x−4=3x+3
−2x−4+−3x=3x+3+−3x(Add -3x to both sides)
−5x−4=3
−5x−4+4=3+4(Add 4 to both sides)
−5x=7
−5x
−5
=
7
−5
(Divide both sides by -5)
x=−7/5
What is the average rate of change of the function f given by f(x) = x4 - 5x on the closed interval (0, 3)?
Answer:
The average rate of change of the function is 22.
Step-by-step explanation:
The given function is :
[tex]f(x)=x^4-5x[/tex]
We need to find the average rate of change of the function on the closed interval (0, 3).
The average rate of change of a function in interval (a,b) is given by :
[tex]R=\dfrac{f(b)-f(a)}{b-a}[/tex]
Here, a = 0 and b = 3
[tex]R=\dfrac{(3^4-5(3))-(0^4-5(0))}{3-0}\\\\=\dfrac{66}{3}\\\\=22[/tex]
So, the average rate of change of the function is 22.
Answer:
22
Step-by-step explanation:
(f(3)-f(0))/3
=66/3
=22

2. Think of the top and middle shelves as two lines cut by a transversal. What type of angles are
Z1 and 25?
Answer:
Angles 1 and 5 are corresponding angles.
Step-by-step explanation:
These are the different types of angles formed by a transversal:
1. Corresponding angles are angles that lie on the same side of the transversal line. Angles 1, 3, 5, 6, 9, and 11 are corresponding angles because they are all on the left side of the transversal (the line that cuts through the other lines). Angles 2, 4, 6, 8, 10, and 12 are corresponding angles because they are all on the right side of the transversal.
2. Alternate interior angles are angles that are nonadjacent angles that lie on opposite sides of the transversal and in between the horizontal lines. Here the alternate interior angles are 3 and 6, 4 and 5, 7 and 10, and 8 and 9.
3. Alternate exterior angles are those that are nonadjacent and lie on the outside of the horizontal lines. In this diagram, angles 1 and 12 and angles 2 and 11 are alternate exterior.
4. Same-side interior angles are angles that lie on the same side of the transversal and in between the horizontal lines. The same-side interior angles in this diagram are angles 3 and 5, 7 and 9, 4 and 6, and 8 and 10.

What percent of 90 is 540?
Answer:
16.67
Step-by-step explanation:
Solution for 90 is what percent of 540:
90:540*100 =
(90*100):540 =
9000:540 = 16.67
Answer:
16.67
Step-by-step explanation:
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100
94/ 540 × 100/ 100
= ( 90 × 100/ 540 ) × 1/ 100
= 16.67/ 100
the answer is 16.67%

2. Change the following statements into coordinate points and then plot them!
a. f(-1)= 1
b. f(2)= 7
c. f(1)=-1
d. f(3) = 0
Answer:
The points are (-1, 1), (2, 7), (1, -1), (3, 0)
Step-by-step explanation:
Let us solve the question
∵ f(x) = y
∴ The coordinates of the point are (x, y)
→ Let us use this fact to find the coordinates of each point
∵ f(-1) = 1
∴ x = -1 and y = 1
∴ The coordinates of the point are (-1, 1)
∵ f(2) = 7
∴ x = 2 and y = 7
∴ The coordinates of the point are (2, 7)
∵ f(1) = -1
∴ x = 1 and y = -1
∴ The coordinates of the point are (1, -1)
∵ f(3) = 0
∴ x = 3 and y = 0
∴ The coordinates of the point are (3, 0)

State the slope and y-intercept of the line with equation y = 9 + 7x
Answer:
The Y intercept is 9, and The Slope is 7x
Answer:
slope: 7 (or 7/1)
y int: 9
Step-by-step explanation:
Slope intercept formula is y=mx+b
(m) is slope
(b) is y intercept
so in
y=9+7x
we can flip the numbers around
y=7x+9
so 7 is our slope and 9 is the y intercept

One type of ladybug has 12 spots and 6 legs. What is the ratio of legs to spots?
Answer:
12:6 or simplified 2:1
Answer:
It would be 1:2
Step-by-step explanation:
since 6 is obviously half of 12, you would simlify it like a fraction

Find the vertex for the graph of the above equation and identify whether it 1 point
is a maximum or minimum. (Use Desmos)*
O (3,6). Maximum
O (-3, 6), Minimum
O (1,8): Maximum
O (1,8), Minimum
Answer:
Answer : d. minimum (-1,3)
The vertex form of quadratic function is
, where (h,k) is the vertex
To get vertex form we apply completing the square method
To apply completing the square method , there should be only x^2
So we factor out 5 from from first two terms
Now we take the number before x (coefficient of x) and divide by 2
=1
Now square it
Add and subtract 1 inside the parenthesis
Now we take out -1 by multiplying 5
Now we factor x^2 +2x+1 as (x+1)(x+1)
h=-1 and k=3
So vertex is (-1,3)
When the value of 'a' is negative , then it is a maximum
When the value of 'a' is positive , then it is a minimum
is in the form of
The value of a is 5
5 is positive so it is a minimum
f(x) is minimum at point (-1,3)

This equation shows how the total distance Warren has walked depends on the number of trips he has made to school d=t+3 The variable t represents the number of trips he has made, and the variable d represents the total distance walked in kilometers. How many trips will Warren have to make in all to walk a total of 12 kilometers?
Answer:
9 trips
Step-by-step explanation:
Given that :
Total Distance walked is dependent on the total number of trips made to school ;
d = t + 3 ;
d = total distance in kilometers ; t = number of trips made ;
Number of trips required to walk a total of 12 kilometers ;
d = 12
Putting d = 12 in the equation ;
12 = t + 3
12 - 3 = t
9 = t
Hence, Number of trips made = 9
The figure shows ST
intersecting plane A at point V. a right angle. Points P, R, and
Q also lie in the plane.
Which statements are true based on the figure? Select all that apply.
Answer:
A,B,E,F those the answer i have EOC review packet done
Step-by-step explanation:
Points, lines and planes are undefined terms in geometry.
The true statements are:
(c) V lies on line ST(d) ST is perpendicular to plane A(e) ST is perpendicular to RVFirst, we test each option to determine the true and false options.
(a) S, V and U are collinear
Points that are collinear are on the same line
S, V and U are not collinear, because they are not on the same line.
Hence, (a) is false
(b) Q, S, T and U are coplanar
Points that are coplanar are on the same plane
Q, S, T and U are not coplanar, because they are not on the same plane.
Hence, (b) is false
(c) V lies on line ST
Point V is the point of intersection of line ST and plane A
This means that point V lies on line ST and plane A
Hence, (c) is true
(d) ST is perpendicular to plane A
Line ST intersects with plane A at point V at 90 degrees.
Perpendicular lines and planes meet at 90 degrees
Hence, (d) is true
(e) ST is perpendicular to RV
Because line ST intersects with plane A at point V at 90 degrees.
Any line drawn from point V would be perpendicular to line ST
Hence, (e) is true
(f) P, R and Q are collinear
Points that are collinear are on the same line
P, R and Q are not collinear, because they are not on the same line.
Hence, (f) is false

the insurance company reduces the price by 4.1%
how much does the insurance cost now?
give your answer rounded to 2DP
Answer:
Current insurance cost = [tex]685.43[/tex] $
Step-by-step explanation:
Given
Original Payment = £714.73Reduced Percentage = 4.1%
Reduced Amount = [tex]4.1\%\:\times\:714.73[/tex]
[tex]=\left(\frac{4.1}{100}\right)\left(714.73\right)[/tex]
[tex]=\frac{41\times \:714.73}{1000}[/tex]

-2x - 69 = -9x + 29
Answer:
x = 98 /7
= 14
Step-by-step explanation:
7x − 98 = 0
7(x − 14) = 0
Answer: x=14
Step-by-step explanation: Let's solve your equation step-by-step.
−2x−69=−9x+29
Step 1: Add 9x to both sides.
−2x−69+9x=−9x+29+9x
7x−69=29
Step 2: Add 69 to both sides.
7x−69+69=29+69
7x=98
Step 3: Divide both sides by 7.
7x/7=98/7
X=14

What is the slope of a line parallel to the line whose equation is 10x – 4y = 24.
Fully reduce your answer.
Answer:
The slope of the line is ⁵/₂.
Step-by-step explanation:
Given;
equation of one of the parallel lines, 10x – 4y = 24.
let the slope of the parallel lines = m, since two parallel lines have equal slopes.
Then slope of the given equation which one of the parallel lines is calculated as;
10x – 4y = 24
4y = 10x - 24
divide through by "4'
[tex]\frac{4y}{4} = \frac{10x}{4} - \frac{24}{4} \\\\y = \frac{5x}{2} - 6[/tex]
the slope , m is the coefficient of x, = ⁵/₂ (when compared to y = mx + c)
Therefore, the slope of the line is ⁵/₂.
ldentify the slope and intercept of the following linear equation.

You can work at most 24 hours per week at nurses aide. So far this week you work seven hours. If the remaining shifts for the week are each six hours long, how many possible full shifts can you work?
Answer:
2 possible full shifts
Step-by-step explanation:
Given
Total number of hours per week= 24hours
Number of hours worked so far= 7 hours
Number of hours remaining =24-7 = 17hours
If each shift remaining are 6hours long then
1shift = 6hrs
x = 17 hours
Cross multiply
6x = 17
x = 17/6
x = 2.83
Hence she can only work 2 possible full shifts
