D. You define if a quadratic equation has an answer or not by the delta (the calculation inside the sqrt on the quadratic formula). So you simply calculate b^2 -4ac, if the answer is equal or greater than zero there is a solution, if not there isn’t. (Consider ax^2+bx+c) Hope it helped :)

JulsSmile [24]

Answer:

${5}^{3} \times {5}^{x} = {5}^{7} \\ 3 + x = 7 \\ x = 4$

$( {q}^{2} )^{y} = {q}^{6} \\ 2y = 6 \\ y = 3$

${1000}^{m} \div {100}^{n} = {10}^{z} \\ \frac{1000 ^{m} }{ {100}^{n} } = {10}^{z} \\ \\ {10}^{m - n} = {10}^{z}$

Can I have the brainliest please?

If x equals 7, then find the matching value for y.<br> -2x-2y=-2

mihalych1998 [28]

Y = -6.
-2(7)-2y=-2

-14-2y=-2

you need to move -14 to the other side by canceling out -14 with +14, and add +14 to -2, giving you -2y=12. -2/12=-6
