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
2(x + y) + 9x +6y
Please answer!
Answer:
11x + 8y
Explanation:
2(x+y)+9x+6y
Distribute:
=(2)(x)+(2)(y)+9x+6y
=2x+2y+9x+6y
Combine Like Terms:
=2x+2y+9x+6y
=(2x+9x)+(2y+6y)
=11x+8y
Answer:
=11x+8y
2x+2y=10
x=1
solve by substitution
Answer:
x = 1 and y = 4
Step-by-step explanation:
2 * 1 + 2y = 10
2 + 2y = 10
2y = 10-2
2y = 8
y = 4
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)

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)

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.
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

Solve the following:
a.) X^2 - 2x – 24 = 0
b.) x^2 - 11x + 18 =0
Answer:
The answer for the first equation is,
X = 6, -4
The answer for second equation is,
X = 9,2
a.) X^2 - 2x – 24 = 0
x^2-6x+4x-24=0
this is expressing negative 2x as the sum of two terms which are negative 6x and positive 4x
x(x-6)+4(x-6)=0
(x+4)(x-6)=0
(x+4)=0. so x=-4
(x-6)=0 so x=6
b.) x^2 - 11x + 18 =0

dan pays £714.73 a year on his car insurance
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]
[tex]=29.30[/tex] $
Current Insurance cost = [tex]714.73 - 29.30[/tex]
= [tex]685.43[/tex] $
Thus,
Current insurance cost = [tex]685.43[/tex] $

Find the range of the graphed function.
The range of the graphed function is -4≤y≤8.
Option (A) is correct.
To find the range of the graphed function.
What is function?A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given that:
It is given that the graph shows parabolic.
The "range" is the vertical extent of the graph.
The range of a function refers to the values of y for which x is defined.
The least value of y from the graph is -4.
The reason is that each box is 2 units, therefore tracing down to the third box on the y-axis gives -4.
Similarly the highest value is 9..
So, the range of the graphed function is -4≤y≤9.
