Answer:
Step-by-step explanation:
The proportion that Alan solved was
x/200 = 8/25
His working as shown was
(8)(x) = (25) (200)
8x = 5000
He divided both sides of the equation by 8. It became
8x/8 = 5000/8
x = 625
The correct steps are
25x = 200 × 8 = 1600
Dividing both sides of the equation by 25, it becomes
x = 1600/25
x = 64
Alan's error were:
1) He got the wrong product when he multiplied 25 by 200.
2)He got the wrong quotient when he divided 5,000 by 8.
Answer:
It should be 1/10
Step-by-step explanation:
3*1 is 3
5*6 is 30
simplify and get 1/10
We know m = 5, x = 3, and y = -2, and that the point slope form is y = mx + b, so plugging these in we can solve for b;
-2 = 5 * 3 + b
-2 = 15 + b
b = -17
So the equation for the line would be;
y = 5x - 17
b is the y intercept, so that is answered (0,-17), to solve for the x intercept you have to plug 0 in for y in the equation, so;
0 = 5x - 17
17 = 5x
x = 17/5
So the x intercept would be (17/5,0)
