{-2x+y=12 => y=12+2x

{3x+2y=38

3x+2(12+2x)=38

3x+24+4x=38 /-24

7x=14 /:7

x=2

y=12+2*2=12+4=16

y=16

Solution: (2; 16)

Answer:

The last choice availablle

Step-by-step explanation:

The way you can tell the points the function has in common with the x-axis (also known as the solutions, roots, or zeros of the functiion) you have to factor it to solve for x. When you throw this into the quadratic formula you get that there is a negative under the square root sign, which is indicative of imaginary solutions. Imaginary solutions do NOT cross the x-axis. So the answer to your problem is the last choice.

7.Austin has no money so he borrowed $28 over eight days from Kayla. How much did Austin borrow from Kayla each day? Show your w

MAXImum [283]

#7. let x = the amount of money he borrows each day. so, the equation would be 8x (because it’s over 8 days, so 8 times x) = 28

so equation: 8x=28
then solve for x, which is 3.5 so $3.50

What is the surface area of the box if it is scaled up by a factor of 10?

Elodia [21]

Answer:

6l², where l is the length of one side.

If the side is increased 10 times,

6(10l)²

=100 x6l²

The surface area increases 100 times. Thus, the new surface area is

272 * 100

= 27,200 sq in
