Answer:
Divide each number by 2 then translate them
Answer:
x = 39
y = 129
Step-by-step explanation:
to find x you do
x +51 = 90
subtract 51 from both sides
x = 39
to find y
we already know part of y is a right angle (90 degrees)
so we need to find the tiny other part
this tiny other part is equal to x
so
90 +39 = 129
Answer:
t^-12
Step-by-step explanation:
you multiply the -2 and 6.
Answer:
B y = -1/2x + 7/2
Step-by-step explanation:
We know that it has a negative slope since the points go from the top left to the bottom right
We can eliminate A and D
The y intercept is where it crosses the y axis
It should cross somewhere between 2 and 4
C has a y intercept of 9 which is too big
Lets verify with a point
x = -4
y = -4(-4)+9 = 16+9 = 25 (-4,25) not even close to being near the points on the graph
checking B
y = -1/2 (-4) +7/2
= 2 + 7/2 = 11/2 = 5.5 it seems reasonable
Answer:
x=3, solution is not extraneous
Step-by-step explanation:
we have
Solve for x
squared both sides
<u><em>Verify</em></u>
For x=3
-----> is true
therefore
x=3, solution is not extraneous
