Answer:

Yes

Step-by-step explanation:

In standard form, this function is written as:

y =  - 5 {x}^{2}  - 4

Because it has the parent function of:

y =  {x}^{2}

It is a quadratic function.

Answer: Yes

Step-by-step explanation:

When you rearrange the equation it would be y=-5x^2-4, and since it is a 2nd degree we can easily say it is a quadratic function.

Answer:

John is 16 and Maya is 11

Step-by-step explanation:

x=Maya's age

x+5=John's age

x+x+5=27

2x+5=27

     -5   -5

2x=22

/2    /2

x=11

x+5=

A line that passes through the points (−5, 7) (10, 1). Using the mx+b format
lianna [129]

Answer:

y=2x-19

Step-by-step explanation:

I'm guessing you mean slope intercept form y=mx+b

If so, first you would have to find the slope of the line

To do that, use the formula y2-y1/x2-x1

Remember you can pick any coordinate pair for this

I will pick 1=y2 -5=y1 10=x2 and 7=x1

When I put that in the equation I get 1-(-5)/10-7

Overall I get 6/3, or 2

Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)

I will pick (10,1)

1=y and 10=x and 2=m

1=2(10)+b

this simplifies to 1=20+b

now subtract 20 from both sides and get -19 = b

Now you have your equation y=2x-19
