Solve by using substitution. =3−8 =−4

garik1379 [7]

Answer:

I'm going to assume that you meant y=3x-8 and y=-4

This means that you would substitute -4 into the spot of y which gives you -4=3x-8. Once solved you would receive x=4/3.

Hope I helped have a nice day :)

Pls help I don’t understand

dmitriy555 [2]

The answer is c. $\frac{46}{9}$

a. $\frac{11}{5}=2.2$ (2.2≠5.11) (2.2 is not equal to 5.11)

b. $5\frac{1}{8}=\frac{5}{8}$ or 0.625 (0.625≠5.11) (0.625 is not equal to 5.11)

c. $\frac{46}{9} =5.11$ (5.11=5.11) (5.11 is equal to 5.11)

Therefore c is the answer

Can someone PLEASE solve this quadratic equation by factoring with the steps? :(

salantis [7]

Answer:

There are no simple factors to this expression. You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:

$y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}$
