The input was one square so multiplied 2 would be 2 squares which is shown on both function machines. Then if you add 5 to the output you can see it because the blue part of the output is shown as a whole instead of 5 parts on the second function machine, so the value is still the same.
Answer:
Joe is correct
Step-by-step explanation:
Given equation:
The exponent outside the bracket is a question mark and the students are trying to determine the value of the question mark.
For ease of answering, let y be the unknown number (question mark):
First, simplify the equation by applying exponent rules to either side of the equation:
Now, apply the exponent rule:
Therefore,
Finally, solve for y:
Therefore, <u>Joe is correct</u> as the unknown number is 6.
Answer:
x is to the side y is up so you´d put A on 4 side 9 up
Step-by-step explanation:
Answer:
2x - 10 = 44 + 8x
7x - 4 = 20 =3x
2(x-3) = -20
15 - 4x + 5 = 32
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*x-10-(44+8*x)=0
Pull out like factors :
-6x - 54 = -6 • (x + 9)
-6 = 0
Solve : x+9 = 0
Subtract 9 from both sides of the equation :
x = -9
x = -9
Move all terms containing
x
to the left side of the equation.

Move all terms not containing

=
24
divide each term by 4
x = 6
2(x−3)=−20
Step 1: Simplify both sides of the equation.
2(x−3)=−20
2x−6=−20
Step 2: Add 6 to both sides.
2x−6+6=−20+6
2x=−14
Step 3: Divide both sides by 2.

x=−7
−4x+20=32
Step 2: Subtract 20 from both sides.
−4x+20−20=32−20
−4x=12
Step 3: Divide both sides by -4.

Answer:
13 and 27
Step-by-step explanation:
y= x+14
x+y=40
x+ x+14=40
2x+14=40
40-14=26
so, 2x=26
26/2
=13
so, x=13 and
and y equal 40-13
y=27
