Answer:
Step-by-step explanation:
-5400/-450
12 minutes
-8x+ 4y= -16
4y= 8x - 16
divide it by 4
y= 2x -4
if x is 0 what is y?
y = 2 (0)-4
y = 4
just put an x value in the equation u will get your y value
1 (0,4)
2 (1,-2)
3 (2,0)
4 (3,2)
5 (4,4)

Answer:</h3>
16) w = 4/15
18) r -16 = 25; Ronald is 41.
<h3>
Step-by-step explanation:</h3>
16) Multiply by the reciprocal of the coefficient of w:
(1/3)·3w = (1/3)·(4/5)
w = 4/15
___
18) Ronald's age is unknown and what we're asked to find. Let r represent Ronald's age in years. Then Wendy's age, being 16 years less than Ronald's, can be represented two ways:
Wendy's age: r-16 . . . . . . 16 years younger than Ronald
Wendy's age: 25 . . . . . . .given
We can equate these two versions of Wendy's age to have a subtraction equation to find Ronald's age:
r - 16 = 25 . . . . . . . the equation
r = 41 . . . . . . . . . . . the solution; found by adding 16 to both sides
