Answer:

Step-by-step explanation:
To find the inverse of a function, switch the x and y values and isolate y. After switching the x and y values of
, we get
.
Now divide by 2 to isolate y:

Answer:
x=7
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
x+30−4x=4x+9−4x
−3x+30=9
Step 2: Subtract 30 from both sides.
−3x+30−30=9−30
−3x=−21
Step 3: Divide both sides by -3.
−3x
−3
=
−21
−3
<u><em>The sides of a rhombus are all congruent (the same length.)</em></u>
Answer:
1:3
2:6
3:9
5:15
Step-by-step explanation:
Ask yourself: What times 3 equals my number?
As you can see 1x3=3 then 2x3=6, 3x3=9, and lastly 5x3=15
This is how you solve the chart.
Ratio of boys to girls = 1 : 3
Unknown constant = x
x + 3x = 24
4x = 24
x = 6
No. of girls = 3 x 6 = 18
If s=side, then each side is 12m.
It got cut off but
12mx12m=144m^2 because mxm=m^2.
