Hello! The x-intercept is where the line crosses the x-axis when y = 0. We already have the expression shown. We will plug in 0 as y to get this:
5x - 8(0) = 40.
As you probably know, anything times 0 is 0, so -8 * 0 is 0. All we have is 5x = 40. Divide each side by 5 to isolate the x. 5x/5 cancels out. 40/5 is 8. There. x = 8. The x-intercept is (8, 0).
Answer:
Step-by-step explanation:
(x + 2)/2 = -2
x + 2 = -4
x = -6
(y + (-9))/2 = -1
y - 9 = -2
y = 7
(-6, 7)
answer is C
Answer:
2/3
Step-by-step explanation:
Look at what you are getting on the right hand question. 10a +10b has a common factor that can be pulled out. It is 10
10a + 10b = 10(a + b)
Now look at the denominator
9x - 9y = 9(x -y)
There are a lot of possible answers.
Mine would be to multiply 3/5 * 10/9
so
(10a + 10b)/(9x - 9y) = 2/3

Step-by-step explanation:
12 + 6 = 18 units.... takes 12 units to go to (0,0) then 6 more units to go to (6,0)
