-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

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)

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.

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

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)

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

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

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]
