The first one and A and the second one is c
Answer:
m represents the slope
Step-by-step explanation:
Remember foil and distributive property
note the invible -1
5a(2x-1)-1(8a-x)(2x-a)
look at first bit
5a(2x-a)=10ax-5a^2
2nd part
-1(8a-x)(2x-a)
-1(16ax-2x^2-8a^2+ax)
-1(17ax-2x^2-8a^2)
-17ax+2x^2+8a^2
now combine the 2 parts
10ax-5a^2-17ax+2x^2+8a^2
2x^2+3a^2-7ax
We know, Point slope form is written as:
y - y₁ = m(x - x₁)
First, We need to Calculate the slope:
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 1) / (-3-2)
m = 1/-5
m = -1/5
Take any one of them: Let's take (-3, 2) as our coordinate:
y - 2 = m(x - (-3))
y - 2 = -1/5(x + 3)
In short, Your Answer would be Option D
Hope this helps!
Answer:
4
Step-by-step explanation:
2x+3(x-4)=8
2x+3x-12=8
5x-12=8
5x-12+12=8+12
5x=20
5x/5=20/5
x=4
