You would need to calculate the unit rate by dividing the y-value by the x-value. 

14/8 = 7/4 

7/4 in decimal form is 1.75

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>

Pls can someone help me with math pls I’m this is my last points..
LiRa [457]

Answer:

Please read all of this! Underlined things are the answers. The area of the entire circle is 19.625

Step-by-step explanation:

(This is a circle so the middle line is the diameter. According to the attachment, the diameter is 5 cm. To find the area, we have to multiply π and the radius squared. The radius is half of the diameter.

5 ÷ 2 = 2.5

2.5² = 6.25

π = 3.14

3.14 x 6.25 = 19.625)

Ignore the top I just realized what I'm supposed to do but I left it there just in case you need help!

<u>The right and left shaded regions areas are 6.28 each.</u>

4 ÷ 2 = 2

2² = 4

3.14 x 4 = 12.56

Since this is a semi circle, we cut it in half.

12.56 ÷ 2 = 6.28

To find the top and bottom shaded region's areas, repeat the same steps.

3 ÷ 2 = 1.5

1.5² = 2.25

3.14 x 2.25 = 7.065

7.065 ÷ 2 = 3.5325

<u>The areas of the the top and bottom shaded regions are 3.5325 each.</u>

Which number satisfies the inequality 12n &lt; 3n + 28?<br> A.) 3<br> B.) 4<br> C.) 5<br> D.) 6
Dafna11 [192]
Let's move the terms with n to one side:
12n < 3n + 28 => 12n - 3n < 28
9n < 28 => n < 28/9
n < 3.1111
The only answer which satisfies this inequality is A.
