The graph of y>x^2-6x+7 contains which of the following points?
schepotkina [342]
We are given the equation that is an inequality, y>x^2-6x+7. In this problem, we are asked to determine points that correctly coincide with the graph. In this case, all we have to do is to substitute x with the number and check whether the answer is less than y. If that is the case, that is the correct answer.

Kyle drove 130 miles in 2.6 hours to watch a baseball game. At what rate did Kyle travel?
IRISSAK [1]

Answer:

50 miles per hour

Step-by-step explanation:

To find rate, we use the rate formula:

r =  \frac{d}{t}

r = rate, d = distance and t = time

Plug in distance and time using the numbers provided:

r =  \frac{130}{2.6}

now to find rate we only need to divide 130 by 2.6 to get r = 50.

A rectangular cardboard sheet has a length that is 1.5 times greater than the width. Is it possible to make a topless box with a
Andreyy89

Answer:

Yes, it is possible  to make a topless box with a volume of 6080 cm3 out of this cardboard sheet.

The dimensions of the cardboard sheet are 54 cm x 36 cm

Step-by-step explanation:

Let

x ----> the length of the cardboard sheet

y ----> the width of the cardboard sheet

we know that

x=1.5y ----> equation A

The volume of the topless box is

V=LWH

where

V=6,080\ cm^3

L=x-2(8)=(x-16)\ cm

W=y-2(8)=(y-16)\ cm

H=8\ cm

substitute

6,080=(x-16)(y-16)8 ----> equation B

substitute equation A in equation B

6,080=(1.5y-16)(y-16)8

6,080/8=(1.5y-16)(y-16)

760=1.5y^2-24y-16y+256

760=1.5y^2-40y+256

1.5y^2-40y+256-760=0

1.5y^2-40y-504=0

Solve for y

Solve the quadratic equation by graphing

The solution is y=36 cm

see the attached figure

Find the value of x

x=1.5y ----> x=1.5(36)=54\ cm

therefore

Yes, it is possible  to make a topless box with a volume of 6080 cm3 out of this cardboard sheet.

The dimensions of the cardboard sheet are 54 cm x 36 cm
