Pani-rosa [81]

Step-by-step explanation:

\frac{1}{100}  =  \frac{1}{ {10}^{2} }  =  {10}^{ - 2}  \\  \\ reason  \\ \:  \because \:  \frac{1}{ {a}^{2} }  =  {a}^{ - 2}  \\  \\  \implies \:  \frac{1}{ {10}^{2} }  =  {10}^{ - 2}

Let B be between A and C. If AB = 3x + 5, BC = 5x - 1, AC = 36, solve for x.
Elina [12.6K]

Answer:

The value of x is 4.

Step-by-step explanation:

Given:

Let B be between A and C.

AB = 3x + 5

BC = 5x - 1

AC = 36

To Find:

x=?

Solution:

B be between A and C as shown in Figure

A-B-C such that

AC=AB+BC           ...........Line Addition Property

Substituting the given values we get

36=3x+5+5x-1=8x+4\\\\\therefore 8x=36-4=32\\\\\therefore x=\dfrac{32}{8}=4\\\\\therefore x=4

The value of x is 4.

How do you do <br><br>f(x)=12x+3 2units left<br>g(x)=<br><br><br>please help I'm confused ​
Mkey [24]

Answer:

g(x) = 12x + 27

Step-by-step explanation:

Take a point in the f(x).

f(0) = 12(0) + 3

f(0) = 3

A point on f(x) is (0,3).

Move the point 2 units left. It will make the x-coordinate decrease by 2.

0 - 2 = -2

A point on g(x) is (-2,3).

Substitute the point and the same slope into the equation of a line. The slope did not change.

y = mx + b

3 = 12(-2) + b

3 = -24 + b

b = 3 + 24

b = 27

Rewrite g(x) using b = 27 and the same slope, m = 12.

g(x) = 12x + 27

Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once.
BaLLatris [955]

Answer:

To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.

Step-by-step explanation:

hope its right
