Answer:

y = x^2 + 5x -3

y-x =2

Replace y in the second equation with the first one:

x^2 + 5x -3 - x = 2

Simplify by combining like terms:

x^2 + 4x -3 = 2

Subtract 2 from both sides:

x^2 + 4x -5 = 0

Fctor the polynomial:

(x-1) (x+5) = 0

Solve for both X's:

x = 1 and x = -5

Now replace x in the second equation with both value and solve for y:

y -1 =2, y = 3

y - -5 =2, y +5 = 2, y = -3

Now combine the sets of answers:

(1,3) and (-5,-3)

Find the missing factor. Write your answer in<br> exponential form.<br> 6^-8 = blank 6^7
Keith_Richards [23]

Answer:

6^ (-15) = x

Step-by-step explanation:

6^-8 = blank 6^7

6^-8 = x* 6^7

Divide each side by 6^7

6^-8 / 6^7 = x 6^7 / 6^7

6^-8 / 6^7 = x

Since the bases are the same, we can subtract the exponents

6^ ( -8-7) = x

6^ (-15) = x

Joseph took a taxi from his house to the airport. The taxi company charged a pick-up
JulsSmile [24]

Answer:

$21.10=3.10+2m.

Step-by-step explanation:

If the total fare was $21.50, then that is what it will all have to equal out to.

They charged a pick-up fee of $3.10. Which means that no matter how far you go, you will pay that. Then an extra $2 per mile. If m is mile, then it would be 2m because it is $2 per extra mile. Then add the pick-up fee of $3.10 and you will get your answer of $21.50=3.10+2m.
