Answer:
y = - 3(x + 2)² + 12
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) = (- 2, 12), thus
y = a(x + 2)² + 12
To find a substitute (- 4, 0) into the equation
0 = a(- 2)² + 12, that is
4a + 12 = 0 ( subtract 12 from both sides )
4a = - 12 ( divide both sides by 4 )
a = - 3
y = - 3(x + 2)² + 12 ← equation in vertex form
Answer:
x= 131
Step-by-step explanation:
This is the commutative property (of addition, but this applies to multiplication as well)
It doesn't matter which order the numbers are added in, the same result will be achieved.
1+2 = 2+1
2*4 = 4*2
Answer:
m∠ABC = 53°
Step-by-step explanation:
m∠ABC + m∠CBD = m∠ABD
m∠ABC + 37° = 90°
m∠ABC = 53°
