PLZZ CAN SOMEONE CHECK MY ANSWERS !!!

Mathematics
1 answer:
larisa86 [58]3 years ago
8 0

Answer:

(1,0)

(5,24)

(-2,3)

Step-by-step explanation:

So we want y=x^2-1 per point.

Let's check them.

(0,1)? Plug in 0 for x and see what y is:

y=0^2-1

y=0-1

y=-1 which is not 1.

(1,0)? Plug in 1 for x and see what y is:

y=1^2-1

y=1-1

y=0 which is what we have for y.

(3,5)? Plug in 3 for x and see what y is:

y=3^2-1

y=9-1

y=8 which is not 5.

(5,24)? Plug in 5 for x and see what y is:

y=5^2-1

y=25-1

y=24 which is what we have for y.

(-2,3)? Plug in -2 for x and see what y is:

y=(-2)^2-1

y=4-1

y=3 which is what y is.

(-4,-17)? Plug in -4 for x and see what y is:

y=(-4)^2-1

y=16-1

y=15 which is not -17.

Anumeha is mowing the lawns for a summer job. For every mowing job, she charges and initial fee of $10 plus a constant fee for e
ExtremeBDS [4]

Answer:

F(t) = 10 +5t

Step-by-step explanation:

Income equals the initial fee plus the hours worked times the hourly rate

We know the initial fee = 10

hours = t

hourly rate =r


F(t) = 10 + r*t

We know a 5 hour job is 35 dollars

35 = 10 + r*5

Subtract 10 from each side

35-10 = 10-10 +5r

25 = 5r

Divide by 5

25/5 = 5r/5

5 =r

The hourly rate is 5

F(t) = 10 +5t

SOVA2 [1]
I think it is 32, bc the value of x is 20 so your problem would look like this; 2 ( (20) - 4 )
