Answer:
4 and 5
Step-by-step explanation:
xy = 20
x = 2y - 3
(2y-3)y = 20
2y^2 - 3y = 20
2y^2 - 3y - 20 = 0
Solve the quadratic equation
you get y = 4, -5/2
Use 5 since it is one of the options
xy = 20, y = 4
x = 5
Answer:
y = 2x - 5
Step-by-step explanation:
Using the slope intercept formula y2 - y1 / x2 -x1...
You get a slope of 2 so y = 2x +b
Then to find b the intercept, you plug in one of the coordinates like so...
1 = 2(3) + b
Then solve to get an intercept of -5.
So the slope-intercept form would be...
y = 2x - 5
Answer:
step 1
3/4+5/4
step 2
dinominator is same so we have to put 4
step 3
3+5/4
step 4
7/4
answer is 7/4
