Answer:
The only thing you will do is to plug the x in the equation.
x = -2 ---> f(x) = -6
x = 0 ---> f(x) = 0
x = 3 ---> f(x) = 9
x = 7 ---> f(x) = 21
f(x) = 3x
f(-2) = <u>3(-2)</u>
f(-2) = -6
f(0) = <u>3(0)</u>
f(0) = 0
f(3) = <u>3(3)</u>
f(3) = 9
21 = 3x
<u>21 / </u><u>3</u> = <u>3x / 3</u>
7 = x
Hope this helps, thank you :) !!
X-y=1 --> x=1+y
plug it into the first equation
3(1+y) + 2y = 8
3+3y+2y=8
5y=5
y=1
plug y into the equation to solve for x
x=1+y
x=1+1
x=2
100 times rolled total
32 times number 2 was rolled
32/100 chance of rolling a 2 on the number cube
Heads was flipped 55 times, 100 total flips so 55/100
(32/100) x (55/100) = .176
176/1000 x 10 =
1760/10000 A
Step-by-step explanation:
In ∆ABC, if <A is 90° and <B is 45° then hypotenuse is BC.
Now,
Cos B= base/height
Cos B= AB/ BC
BC= AB/cos 45°.
