Answer:
-3
Step-by-step explanation:
Plug 4 in for every x
(3*4)-4=8
(4^2)-1=15 [(4^2) is 4*4]
(2*(4^2))-15= 15 [because of PEMDAS the exponent comes first and then multiply by 2 then subtract]
Perimeter is the sum of the lengths so add up all the sides from above
8+15+15=38
Answer:
Step-by-step explanation:
Let:
We need to eliminate one of the variables, so let's use elimination method. First multiply (1) by 2
Now subtract (2) from 2*(1) in order to eliminate x:
Solving for y:
Multiplying both sides by -1
Finally, replacing the value of y in (1)
Solving for x:
add 41 to both sides:
Multiply both sides by 1/2:
Answer:
its an equivalent equation
Step-by-step explanation:
are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.
the sequence is:
Translation, then reflection.
The correct option is the second one.
<h3>
What combination of transformations is shown?</h3>
We start with figure 1.
In the image, we can see that the image is shifted 4 units up and 4 units left to make figure 2.
Then you can see that the image is reflected across a horizontal line to make figure 3, you can see that because now the "L" is facing upwards.
Then the sequence is:
Translation, then reflection.
The correct option is the second one.
