Answer:

The slope is 2.25

The y-intercept is 3

Step-by-step explanation:

Assuming from the cut off picture, that we need to find the slope of ...

y=2.25x +3

y=mx+b form makes it easy to identify the slope and the y-intercept.

m is the slope and b is the y-intercept. Anything number that is in place of m, is the slope; and any nother in place of b is the y-intercept.

In that case, 2.25 is the slope and 3 is the y-intercept

Solve (x +9)2 = 25.
alexandr1967 [171]

Answer:

x =  - 4 \: or \: x =  - 14

Step-by-step explanation:

We have been given the equation

(x + 9) {}^{2}  = 25

and we are asked to apply the square root property of equality to our given a equation and isolate the variable

First, take the square root of both sides of our equation

\sqrt{(x + 9) {}^{2} }  =  \sqrt{25}

x + 9 =  \: 15

x + 9 = 5 \: or \: x + 9 =  - 5

x + 9 - 9 = 5 - 9 \: or \: x + 9 - 9 =  - 5 - 9

x =  - 4 \: or \: x =  - 14

<em>THEREFORE, THERE ARE TWO SOLUTIONS FOR OUR GIVEN EQUATION</em>

<em>x + 9 = 5 \: then \: x =  - 4. \\ x + 9 =  - 5 \: then \: x =  - 14</em>

<u><em>PLEASE</em><em> </em><em>MAKR</em><em> </em><em>ME</em><em> </em><em>BRAINLIEST</em><em> </em><em>IF</em><em> </em><em>YOU</em><em> </em><em>ARE</em><em> </em><em>HAPPY</em><em> </em><em>WITH</em><em> </em><em>THE</em><em> </em><em>ANSWER</em></u>
