n your notebook, set up the following subtraction in a vertical format and select the correct answer. Reduce 7y + 2y 2 - 7 by 3

exis [7]

Answer:

$\frac{2y^2+7y-7}{3-4y}$

Step-by-step explanation:

We are given

$\frac{7y+2y^2-7}{3-4y}$

we can rewrite it as

$\frac{2y^2+7y-7}{3-4y}$

we know that

2y^2+7y-7 can not be factored

so, we can not reduce this expression

because this is the only way to reduce it

so, we get reduced form as

$\frac{2y^2+7y-7}{3-4y}$

Find the distance between each pair of points.

scoundrel [369]

Answer:

(-1, -1) and (-4,5)

Distance between them ,

$\sqrt{ {( - 4 + 1)}^{2} + {(5 + 1)}^{2} }$

$= \sqrt{ {( - 3)}^{2} + {(6)}^{2} }$

$= \sqrt{9 + 36} = \sqrt{45} = 3 \sqrt{5}$

For what values of x does 25 Superscript x Baseline = 5 Superscript x squared minus 3?

umka2103 [35]

For this case we have the following equation:

$25^{x} = 5^{ x^2-3}$

Rewriting we have:

$5^{2 (x)} = 5^{ x^ 2-3}\\5^{ 2x} = 5^{ x^ 2-3}$

For expressions to be equal, exponents must be equal. So:

$2x = x ^ 2-3\\x ^ 2-2x-3 = 0$

To factor, we look for two numbers that, when multiplied, result in -3 and when added, result in -2. These numbers are -3 and 1.

$(x-3) (x + 1) = 0$

Thus, the roots are:

$x_ {1} = 3\\x_ {2} = - 1$

Answer:

$x_ {1} = 3\\x_ {2} = - 1$
