Answer:
The unknown is 44
Step-by-step explanation:
We need to solve for x in the proportion given by :
11 / 1 = x / 4
multiply both sides by 4 to isolate x
11 * 4 / 1 = x
x = 44
Answer:
B
Step-by-step explanation:
Its B Becuase idk tbh i need it too :(
The function given to us is : 
We want to see which function represents the horizontal compression of f(x) by a factor of 4
We can compress a function horizontally by multiplying the x by a constant number, in this case multiplying x by 4
So horizontal compression of 
This matches with the option B = 
Hence, your answer (B) is correct.
Answer:
Endless
Step-by-step explanation:
There are endless possibilities for x, because 1 to the power of any x will always be 1.
2x + 3y = 1
y = 3x + 15
Get the same variables on each side
3y = 1 - 2x
y = 15 + 3x
Multiply both sides of that second equation by 3 so we can subtract.
3y = 1 - 2x
3y = 45 + 9x
Subtract the equations from each other.
0 = -44 - 11x
Solve.
44 = -11x
-4 = x
Use x in an earlier equation to find y.
y = 3x + 15
y = 3 * -4 +15
y = -12 + 15
y = 3
x = -4, y = 3
