Answer:A= 7
Step-by-step explanation:
y=mx+b
512=114x+134
subtract 134 from both sides of the equation,
378=114x
Divide 144 from both sides of the equation to get x by itself
x=6.25
you'll round up because you can't really have a quarter day.
A= 7
Answer:
y = - 8x² + 6
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) = (0, 6), thus
y = a(x - 0)² + 6, that is
y = ax² + 6
To find a substitute (- 1, - 2) into the equation
- 2 = a(- 1)² + 6, that is
- 2 = a + 6 ( subtract 6 from both sides )
- 8 = a
y = - 8x² + 6

Answer:
B) x=12
Step-by-step explanation:
x+22+4x+2= 5x+24
5x+24=84
5x=60
x=12
