Answer:

y= -12x^2 -72x + 101(standard form)

y= -12(x+3)^2+7(vertex form)

Step-by-step explanation:

Standard form : y=ax^2 + bx + c

Using the vertex(h,k) we can find the vertex form of the equation which is:

y = a(x-h)^2+k

y=a(x+3)^2+7

Because we have a point we can use that to find the slope:

-5=a(-2+3)^2+7

-5=a(1)^2+7

-5-7=a

a=-12

So, in standard form:

y=-12(x+3)^2+7

y=-12(x^2+6x+9)+7

y= -12x^2 -72x -108+7

y= -12x^2 -72x- 101

What's 76×32÷5+(19×92)-15×2? Need help ASAP

arsen [322]

Answer:

2204.4

Step-by-step explanation:

Okay so we want to always use order of operations: PEMDAS

Sop first we do what is in the parenthesis. 19*92 is 1748.

Now, going from left to right, we do multiplication and division. 76*32 is 2432. Then we divide that by 5 to get 486.4. And the last bit is 15*2 which is 30.

Your equation now is 486.4+1748-30.

The final answer is 2204.4

Your answer would be D you would add up all the days together then just put the clear days together to get 17/30 that then reduces to .57

If point A is located at (-3,-1) and there are 10 points between A and B, what could be the possible coordinates for point B?

Nataly [62]

Answer:

Step-by-step explanation:

By drawing the point (-3,-1) in the coordinate plane we find the graph shown below. Since there are 10 points between points A and B, we need to start at point A and then we have to move 11 units either to the right, to the left, up, or down .

1. MOVING TO THE RIGHT:

From point A, move 11 units horizontally to the right to come to point B:

(-3+11, -1) = (8, -1)

2. MOVING TO THE LEFT:

From point A, move 11 units horizontally to the left to come to point B:

(-3-11, -1) = (-14, -1)

3. MOVING UPWARD:

From point A, move 11 units vertically upward to come to point B:

(-3, -1+11) = (-3, 10)

4. MOVING DOWNWARD:

From point A, move 11 units vertically downward to come to point B:

(-3, -1-11) = (-3, -12)

So this are the basic movements you can get to find point B. You also can move diagonally upwards or downwards in whose case you would find other four points. The graph below shows a red point which is A, and the other points are in black color and represent B.
