Answer 1

Answer:

12 and (-12)

Step-by-step explanation:

Solve for x.

x^2= 144

square root both sides and get,

x= 12

and

x= (-12)

remember to put your negative and 12 into parenthesis because you are multiplying the negative as well.

Answer 2

Answer:

x = 12

x = -12

Step-by-step explanation:

Step 1: Take the square root of both sides.

[tex]\sqrt{x^2} =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x = 12[/tex] or [tex]x = -12[/tex]

Therefore, x = 12 and x = -12 are the answers.

Sheila can ride her bicycle 6,000 meters
in 15 minutes. How far can she ride her
bicycle in 2 minutes?

Answers

If Sheila can ride her bike 6000 meters in 15 minutes, then you can divide
6000 ÷ 15 to find how far she can ride in 1 minute.

6000 ÷ 15 = 400.

So, Sheila can ride her bike 400 meters in 1 minute.
To find how many meters she can ride in 2 minutes, multiply 400 by 2.

400 x 2 = 800.

Sheila can ride her bicycle 800 meters in 2 minutes.

how many solutions do the following have? **NEED WORK SHOWN ON HOW TO SOLVE EACH ONE!!

6r + 7 = 13 + 7r
-14 + 6b + 7 – 2b = 1 + 5b
8x + 4(4x + 3) = 4(6x + 4) - 4

Answers

I gotchu :)

1) 6r + 7 = 13 + 7r    - Subtract 6r from both sides...

   7 = 13 + r       - Subtract 13 from both sides....

 r = -6   Check answer (don't need this part)

 6(-6) + 7 = 13 + 7(-6)

  -36 + 7 = 13 -42

   -29 = -29  ( It works )

2) -14 + 6b + 7 - 2b = 1 + 5b    - Combine like terms...

   -7 + 4b = 1 + 5b        - Add 7 to both sides....

    4b = 8 + 5b       - Subtract 5b from both sides....

     -b = 8            - Divide both sides by -1

      b = -8

3) 8x + 4(4x+3) = 4(6x + 4) - 4     - Distributive property

   8x + 16x + 12 = 24x + 16 - 4        Combine like terms

   24x + 12 = 24x + 12       - Both terms equal each other

    0 = 0

Since both terms equal each other, all numbres fit.

The value of y is directly proportional to the value of x. When x=3.5, the value of y is 14. What is the value of y when x = 28?

Answers

Answer:

x = 7

Step-by-step explanation:

y = 14

14 x 2 = 28

Therefore:

3.5 x 2 = 7

Value of y is 112 when value of x is 28

Given that;

Value of y is 14 when x = 3.5

Find:

Value of y when value of x = 28

Computation:

We know that, y is directly proportional to x

So,

[tex]Value\ of\ y = 14[\frac{28}{3.5} ] \\\\Value\ of\ y = 14[8]\\\\Value\ of\ y = 112[/tex]

Answer:

f(2) = -2

Step-by-step explanation:

plug in 2 to wherever x is in this statement:

f(2) = -2(2^2) - 2(2) + 10

f(2) = -2(4) - 4 + 10

f(2) = -8 - 4 + 10

f(2) = -2

f(2)= -2x^2 -2x +10
-2(4) -2(2) +10
-8 -4 +10
