Answer:
The Answer is: y - 8 = 5/3(x - 3)
Step-by-step explanation:
Given the y intercept form:
y = 5/3x + 3
Note that the slope is 5/3.
Find a point on the line.
Choose x = 3, solve for y:
y = 5/3(3) + 3
y = 5 + 3
y = 8
This give you the point:
(3, 8)
Use this to substitute into the point slope equation:
y - y1 = m(x - x1)
y - 8 = 5/3(x - 3)
Answer:
1/4x^2 - 1/4x - 1/4
Step-by-step explanation:
I multiplied the two binomials at the top to get 6x^2 + x -2 and I divided it by 24x^2 - 4x - 8 and simplified it to get 1/4x^2 - 1/4x - 1/4
Answer:
Step-by-step explanation:
-3(y²+4y+4)-5+6y
=-3y²-12 y-12-5+6 y
=-3y²-6y-17
Answer:
S = 2
Step-by-step explanation:
1st step: Simplify both sides of the equation
4/5 s - 3/4 s = 1/10
4/5 s + -3/4 s = 1/10
(4/5 s + -3/4 s) = 1/10 (combine like terms)
1/20 s = 1/10
1/20 s = 1/10
step 2: multiply both sides by 20
20 * (1/20 s) = 20 * (1/10)
s = 2
Hope this helped!
