Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is y = m x + b , where m is the slope and b is the y intercept.
y = m x + b
Find the values of m and b using the form y = m x + b .
m =− 5 3 b = 2
The slope of the line is the value of m , and the y-intercept is the value of b .
Slope:
− 5 3
y-intercept: 2

Rewrite the expression.
f ( 0 ) = − 5 ⋅ ( 0 ) 1 + 2
Divide 5 ⋅ ( 0 ) by 1 .
f ( 0 ) = − ( 5 ⋅ ( 0 ) ) + 2
Multiply 5 by 0 .
f ( 0 ) = − 0 + 2
Multiply − 1 by 0 .
f ( 0 ) = 0 + 2
Add 0 and 2 .
f ( 0 ) = 2
The final answer is 2 .

Step-by-step explanation:
y=0,3
x=-4,0
(-4,3)
The required coordinate of the image of p is under y = -1 is given as (-4, 4).
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate the y is called ordinate.
Here,
Coordinates of point P = (-4, 3)
Now,

Cooper is blocking off several rooms in a hotel for guests coming to his wedding. The hotel can reserve small rooms, that can room 2 people, and large rooms, that can room 4 people. How many wedding guests could stay in the hotel if Cooper reserved 12 small rooms and 11 large rooms? How many wedding guests could stay in the hotel if Cooper booked ss small rooms and ll large rooms?
Answer:
Step-by-step explanation: s = small room = 2
l = large room = 4
12s + 11l = 28 + 22 = 50
as I said before s = 2 and l = 4
s*s + l*l = 2*2 + 4*4 = 4 + 16 = 20

You are shoveling snow from the sidewalks around your neighborhood after a big snowstorm. You work at a steady rate, shoveling 10 feet of sidewalk in 40 minutes. 1) At this rate, how many minutes will it take you to shovel 75 feet of sidewalk?
Answer:
300 minutes
Step-by-step explanation:
Given
10 feet in 40 minutes
Required
Determine the time to shovel 75 feet
Let the required be represented with x
First, we need to represent the given and required as ratios.
[tex]Given = 10 : 40[/tex]
[tex]Required = 75 : x[/tex]
Since you work at steady rate, then both ratios are equivalent.
[tex]10 : 40 = 75 : x[/tex]
Convert to fractions
[tex]\frac{10}{40} = \frac{75}{x}[/tex]
[tex]\frac{1}{4} = \frac{75}{x}[/tex]
Solve forx
[tex]x * 1 = 75 * 4[/tex]
[tex]x = 300[/tex]

Jacinto está cercando un terreno de forma rectangular. Cuando lleva puesto alambre a dos lados consecutivos de la tierra, se da cuenta que ha gastado 170 m de alambre. Si sabe que la diagonal del rectángulo mide 130 m, ¿cuáles son las dimensiones y el área del terreno?
Answer:
Step-by-step explanation:
Given the perimeter of the rectangular shape = 170m
Length of the diagonal = 130m
Perimeter = 2L + 2W
diagonal d² = L² + w²
L is the length of the terrain
w is the width
140 = 2L + 2W
70 = L+W ..... 1
130² = L²+w² ..... 2
from 1, L = 70-w
substitute into 2;
130² = (70-w)²+w²
130² = 4900-140w + 2w²
16900 = 4900-140w + 2w²
2w²-140w - 12000 = 0
w²-70w - 6000 = 0
On factorizing;
(w+50)(w−120) = 0
w - 120 = 0
w = 120 m
Since L = 70 - w
L = 70 - 120
L = -50m
Hence the dimension is 120m by 50 m

Step-by-step explanation:
Given
[tex]Attempts = 15[/tex]
[tex]Scored = 40\%[/tex]
Required
Determine the number of goals scored
To do this, we simply multiply the number of attempts by the percentage scored.
[tex]Number = Attempts * Scored[/tex]
[tex]Number = 15 * 40\%[/tex]

You are running a concession stand at a basketball game. You are selling hotdogs and sodas. Each hotdog cost $1.50 and each soda cost $0.50. At the end of the night you made a total of $78.50. You sold a total of 87 hotdogs and sodas combined. How many hotdogs did you sell?
Answer:
35 hotdogs
Step-by-step explanation:
You are running a concession stand at a basketball game. You are selling hotdogs and sodas.
Let the number of hot dogs be represented by x
The number of soda be represented by y
You sold a total of 87 hotdogs and sodas combined
x + y = 87
x = 87 - y
Each hotdog cost $1.50 and each soda cost $0.50. At the end of the night you made a total of $78.50.
Hence we have the equation:
$1.50 × x + $0.50 × y = $78.50
1.50x + 0.50y = 78.50
Substitute 87 - y for x
1.50(87 - y) + 0.50y = 78.50
130.5 - 1.50y + 0.50y = 78.50
Collect like terms
- 1.50y + 0.50y = 78.50 - 130.50
-1.00y = -52
y = -52/-1
y = 52 sodas
How many hotdogs did you sell?
Using the equation:
x = 87 - y
x = 87 - 52
x = 35 hotdogs
Hence, you sold 35 hotdogs
