Graph f(x) = 3/2x + 2.
Use the line tool and select two points to graph the line.
Answer:
(0,2) and (2,5)
Step-by-step explanation:
slope of 0 and passes through (7, 4)
Answer:
y = 4
Step-by-step explanation:
Assuming you require the equation of the line.
A line with a slope of zero is a horizontal line parallel to the x- axis, with equation
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (7, 4 ) with y- coordinate 4, thus
y = 4 ← equation of line
Stephanie ran three sprints during practice. Her first sprint was 175 yards, her second sprint was 150 yards, and her third sprint was 225 yards. What was the total distance that Stephanie sprinted?
Answer:
Stephanie sprinted 550 yards.
Step-by-step explanation:
Given that,
Stephanie ran three sprints during practice.
Her first sprint was 175 yards, her second sprint was 150 yards, and her third sprint was 225 yards.
We need to find the total distance that Stephanie sprinted. It is simply equal to the sum of all above sprints.
Distance = 175 yards + 150 yards + 225 yards
= 550 yards
Hence, Stephanie sprinted 550 yards.

Step-by-step explanation:
Slope is:
[tex]\frac{Change of y}{Change of x}[/tex]
Since there is no change of the y value, there is no slope.

Fred has 45 football cards. Scott has 1/5 as many football cards as Fred. How many football cards does Scott have?
Answer:
9
Step-by-step explanation:
Scott has 45 * 1/5 football cards
45 / 5 can be simplified to 9
Answer:
Scott has 9 football cards.
Step-by-step explanation:
If Scott has 1/5 as many football cards as Fred, then the number of football cards Fred has times 1/5 would result in the number of football cards Scott has;
Fred * 1/5 = Scott
45 * 1/5 = 9
y = x + 2
y = 2x - 5
what is x and y
Answer:
x= 7 y= 9 (7,9)
Step-by-step explanation:
solve by using system if equations. multiply top answer by 2, giving u 2y=2x+4 and y=2x-5 subtract the equations. y=9 (the x cancels out) then put 9 in for y. 9=x+2. subtract 2. giving u 7. and now x =7

Julio considers the reduction of the triangle. What is the correct cross product that he should use to solve for the missing dimension? (8)(12) = 21x (8)(21) = 12x (12)(8) = 12x (12)(21) = 8x
Answer:
(8)(21) = 12x
Step-by-step explanation:
(8)(12) = 21x
(8)(21) = 12x
(12)(8) = 12x
(12)(21) = 8x
Opposite : Adjacent
12 in : 21 in
Opposite : Adjacent
8 in : x in
Equate both ratios to solve for x
12 : 21 = 8 : x
12 / 21 = 8 / x
Cross product
(12)(x) = (21)(8)
12x = 168
x = 168 / 12
= 14
x = 14

A car dealership has 240 cars in the parking lot and 17.5% of them are wrecked of the other six cars in the lot each color has the same number of cars every one of the colors black how many black cars are there in total total
Answer:
33 cars
Step-by-step explanation:
The computation of the number of black cars in total is shown below:
Given that
There is a car dealership of 240 cars
And,17.5% of them are wrecked
So, the wrecked cars is
= 17.5% of 240 cars
= 42
Now the number of other cars would be
= 240 - 42
= 198
And it is mentioned that there are other six colors lot
So the number of black cars would be
= 198 ÷ 6
= 33 cars
The system shown is blank.

1. Ryan and Rachel attended the weekend games at the neighborhood stadium and bought some food at the stands Ryan paid $7.10 for 3 corndogs and 1 coke Rachel paid $7.20 for 2 corndogs and 2 cokes. How much is each corndog?
Please help :( I’ll give you brainiest ♡
Answer:
$1.75
Step-by-step explanation:
Set up a system of equations where x is the cost of a corndog and y is the cost of a coke:
3x + y = 7.1
2x + 2y = 7.2
Solve by elimination by multiplying the top equation by -2
-6x - 2y = -14.2
2x + 2y = 7.2
Add them together:
-4x = -7
x = 1.75
So, the cost of one corndog is $1.75

Find m∠2. pls help!!!
Explanation:
The green and red angles are alternate exterior angles. They alternate on either side of the transversal line. They are exterior because they are outside the parallel lines (think of the interior region as a river and the exterior regions as the shorelines).
Recall that alternate exterior angles are congruent when we have parallel lines. This is similar to how alternate interior angles are congruent due to parallel lines.
Since the angles shown are congruent, this must mean angle 2 is also 130 degrees.
7. A city lot is twice as long as it is wide, If its perimeter is 480 units, what are the dimensions of the lot?
Answer:
Step-by-step explanation:
P = 480
P = 2 length + 2 width
but we also know that
2width = length
so plug that into the length
P = 2(2width) + 2 width
480 = 4 width + 2 width
480 = 6 width
80 = width
160= length
see?
