The standard form of the parabola is x = -4/3y² -40/3y -103/3
What is parabola?
A parabola is an approximately U-shaped, mirror-symmetrical planar curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. One way to describe a parabola is with a point and a line.
x = -4/3(y +5)² -1
Solve for x.
x = (4y² +40y +103)/(-3)
x = -4/3y² -40/3y -103/3 . . . . 'standard form' in the US
__
Taking our clues from the graph*, we can write the vertex form equation as ...
x = -4/3(y +5)² -1 . . . . . . 'standard form' in other places
____
* The vertex is (-1, -5), so for some leading coefficient, the equation will be ...
x = a(y -(-5))² +(-1) = a(y +5)² -1
The value of 'a' is the scale factor. Here, that is the difference between the parabola value (x = -2 1/3) and the vertex value (x = -1) one unit away from the vertex.

Answer:
-58
Step-by-step explanation:
-7*8 = -56
So -56/8= -7
But we have a +2 there, so do the opposite. So -56-2. is -58.
(-58+2) / 8 = -7
Answer:
Rate
Step-by-step explanation:
When you have two quantities and place one over the other, i.e. miles/hour, you get a rate, such as a rate of change .
The measure of the angle ∠ABC is 110° and the measure of the reflex angle ∠CBD is 70°.
<h3>What is an angle?</h3>
Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
The measure of the angle ABC will be
∠ABC = 110°
The angle ∠ABC and ∠CBD are the linear angles. Then we have
∠ABC + ∠CBD = 180°
110° + ∠CBD = 180°
∠CBD = 70°
