Answer:
1. y = -2/3x + 2
2. y = 2/4x + -3
3. y = 1x -1
Answer: see below
Step-by-step explanation:
Step 1: Find the slope (m) using the formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Step 2: Plug in the slope (m) and one of the points (x₁, y₁) into the Point-Slope formula. y - y₁ = m(x - x₁)

Step 1: [tex]m=\dfrac{-2-0}{0-3}\quad =\dfrac{-2}{-3}\quad =\dfrac{2}{3}[/tex]
Step 2: [tex]y-0=\dfrac{2}{3}(x-3)[/tex]
[tex]y=\dfrac{2}{3}(x-3)[/tex]
[tex]\large\boxed{y=\dfrac{2}{3}x-2}[/tex]
2. (0, -3) and (-4, -5)
Step 1: [tex]m=\dfrac{-3-(-5)}{0-(-4)}\quad =\dfrac{-3+5}{0+4}\quad =\dfrac{2}{4}\quad =\dfrac{1}{2}[/tex]
Step 2: [tex]y-(-3)=\dfrac{1}{2}(x-0)[/tex]
[tex]y+3=\dfrac{1}{2}x[/tex]

A handyman charges $150 plus $25 per hour for house painting. A painter charges $55 per hour. How many hours would a job have to take for both fees to be the same?
Answer:
The numbefr of hours spent painting each house
Step-by-step explanation:
You know that the cost of painting will include the product of the hourly cost (55 or 25) and the number of hours.
The equations have x multiplied by 55 or 25, so it is reasonable to assume that ...
Answer: Five hours.
150 + (25 x 5) = 275 and 55 x 5 = 275. I hope this helps you out!

Given the definitions of f(x) and g(x) below, find the value of g(f(-3)).
Answer:
-11
Step-by-step explanation:
f(x) = 5x + 11
g(x) = x^2 + 4x - 11
g(f(-3)) = ?
f(-3) = 5(-3) + 11
= -15 + 11 = -4
g(f(-3)) = g(-4) = -(4)^2 + 4(-4) - 11
= 16 - 16 - 11 = -11
A function assigns the value of each element of one set to the other specific element of another set. The value of g(f(-3)) is -11.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given f(x)=5x+11 and g(x)=x²+4x-11, therefore, we can write the value of g(f(x)) as,
g(f(x)) = (5x + 11)² + 4(5x + 11) - 11
= 25x² + 121 + 110x + 20x + 44 - 11
= 25x² + 130x + 154
Now, substitute the value of x as -3 in the function g(f(x)), therefore, we can write,
g(f(-3)) = 25x² + 130x + 154
= 25(3)² + 130(-3) + 154
= 225 - 390 + 154
= -11
Hence, the value of g(f(-3)) is -11.

Find the value of b if the graph of the equation y=−5x+b goes through the G(4, 3) point.
Answer:
b = 23
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
y = -5x + b
G(4, 3)
Step 2: Find y-intercept b
Substitute point: 3 = -5(4) + bMultiply: 3 = -20 + bAdd 20 to both sides: 23 = bStep 3: Write linear equation
y = -5x + 23

A map shows a section of Interstate 94 that forms a straight line. A family plans to drive 72 miles on Interstate 94 from St Paul, MN to Elk Mound, WI. They drive for 20 miles, and then decide they will stop halfway through their trip to eat. How much farther do they need to drive before they stop for dinner?
Answer:
16 miles
Step-by-step explanation:
Given that:
Total distance of the trip = 72 miles
They have decided to stop half way their trip i.e. they will stop at a distance [tex]\frac{72}{2} =36[/tex] miles from the starting point.
Also, given that they have already traveled for 20 miles.
To find:
How much farther do they need to drive before they stop for dinner?
Solution:
Distance already covered = 20 miles
Distance to be covered before stopping for dinner = 36 miles
Distance to be covered more = Total distance to be covered before stopping - Distance already covered
[tex]\Rightarrow 36-20 =\bold{16\ miles}[/tex]

f(x) = -6x + 4
f (x) = 28
Answer:
x = - 4
Step-by-step explanation:
Given f(x) = - 6x + 4 and f(x) = 28, then equating
- 6x + 4 = 28 ( subtract 4 from both sides )
- 6x = 24 ( divide both sides by - 6 )
