Answer:
Parallel lines have the same slope. Solve for the slope in the first line by converting the equation to slope-intercept form. 3x + 4y = 12. 4y = –3x + 12.
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
Use rule of three
15 => 20
x => 12
x = 9
Answer:
y = 2(x - 1)² - 3
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (1, - 3), thus
y = a(x - 1)² - 3
To find a substitute (- 1, 5) into the equation
5 = a(- 1 - 1)² - 3
5 = (- 2)²a - 3 ( add 3 to both sides )
8 = 4a ( divide both sides by 4 )
a = 2
Thus
y = 2(x - 1)² - 3 ← in vertex form
Answer:
y = 6x - 13
