What are the solutions to the system of equations <br> {-x+y=4<br> {y+12=x^2+x
Gnoma [55]

Answer:

Step-by-step explanation:

y=4+x          ............................................ (1)

y=x^2+x-12  ............................................ (2)

now equate both (1) and (2)

4+x=x^2+x-12

=>x^2=16

x=-4,4

now substitute the values of x ,

when x=-4 , y becomes 0

when x=4  , y becomes 8

so, solution set:

(-4,0) and (4,8)

9. If it takes Joel 30 seconds to install each
DaniilM [7]

Answer:

20

Step-by-step explanation:

Since we have given that

Dimensions of a triangle he has to use for fencing are

15 feet, 8 feet, and 20 feet.

1) For making it a right triangle it must satisfy the "Pythagoras theorem" which states that

H^{2} = B^{2} + P^{2}

20^{2} = 15 + 8^{2}

400 \neq  225 + 64

400 \neq 289

No, it will not be able to make a right triangle.

2) Joel cut the longest piece of wood in order to make a right triangle.

So, from above we get that

\sqrt{} 289 = 17 feet

So, the longest side must be 17 feet.

It takes him 30 seconds to install each foot of fencing,

The total perimeter of fencing will be

17 + 15 + 8 = 40 feet

So, for 1 foot he needs = 30 seconds

For 40 feet, he will need

40 × 30 = 1,200 seconds

1200/600 = 20 minutes

Hence, he needs 20 minutes to install all of the fences.
