Answer:
y = 1
x = -2
Step-by-step explanation:
During the substitution method, you are substituting one function into another. Because both functions are set equal to "x", you can make the functions equal each other. This allows you to 'get rid' of the "x" variable and simplify to find the value of "y".
5A) x = -2y
5B) x = 2 - 4y
-2y = 2 - 4y <----- Set both equations equal
2y = 2 <----- Add 4y to both sides
y = 1 <----- Divide both sides by 2
Now that you know what "y" equals, you can plug that value into the "y" variable into one of the equations. This will allow you to then simplify and find the answer for "x".
x = -2y <----- Equation 5A
x = -2(1) <----- Plug 1 into "y"
x = -2 <----- Multiply -2 and 1
Answer:
No, she did not multiply the negative integer tiles by the other negative integer tiles correctly.
Step-by-step explanation:
It looks like each time you want another term, you take
the last one and multiply it by 4.
2 x 4 = 8
8 x 4 = 32
32 x 4 = 128 .
So if that's the pattern, then the next three terms are ...
128 x 4 = <em>512</em>
512 x 4 = <em>2048
</em>and<em>
</em>2048 x 4 = <em>8192</em>
Answer: y = 5x - 7
Step-by-step explanation:
y = mx + b, where m = slope
We plug in the point, where x = 2, and y = 3
y = 5x - b
3 = 5(2) - b
3 = 10 - b
b + 3 = 10
b = 7
y = 5x - 7
