Answer:
A) y = -24
Step-by-step explanation:
y = 5x - 4
y = 6x
substitute for y:
5x - 4 = 6x
reduce:
x = -4
y = -24
<span>5(x + 7) = 5(x) + 5(7) = 5x + 35</span>

Answer:
y=2x+8
Step-by-step explanation:
Alright so, to find the equation, we need to find the slope first. We can do that by turning the input and output into coordinates.
(1,10) and (2,12)
To find the slope, we do:
![\frac{12 - 10}{2 - 1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%20-%2010%7D%7B2%20-%201%7D%20)
Which equals to 2
So right now we can say that the equation is:
y=2x+b
In order to find b, the constant, we just need to plug in the y values and x value of a coordinate:
10=2(1)+b
10=2+b
8=b
So now we can say that the equation is:
y=2x+8
Answer:
see explanation
Step-by-step explanation:
The excluded values are any values of x that make the function undefined
Given
![\frac{1}{(x+4)(x-2)(x-5)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%28x%2B4%29%28x-2%29%28x-5%29%7D)
The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that x cannot be.
(x + 4)(x - 2)(x - 5) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
x - 5 = 0 ⇒ x = 5
x = - 4, x = 2, x = 5 are the excluded values
