Y = 4x - 1
y = 2x - 5
4x - 1 = 2x - 5
4x - 2x = -5 + 1
2x = -4
x = -4/2
x = -2
y = 4x - 1
y = 4(-2) - 1
y = -8 - 1
y = -9
solution is : -2,-9)
Answer:
x = 4
Step-by-step explanation:
You have to remember the "Quotient Rule" for exponent having same base.
The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.
Here,
base = 3
exponents = 2x + 1 , x + 5
3^(2x + 1) = 3^( x + 5)
3^(2x + 1) / 3^(x + 5) = 1
3^((2x + 1) - (x + 5) )= 1
3^(2x + 1 - x - 5) = 1
3^(2x - x +1 - 5) = 1
3^(x - 4) = 1
log 3^(x - 4) = log(1)
(x - 4) (log (3)) = 0
log(3) = 0 rejected
x - 4 = 0 accepted
x = 0 + 4
x = 4
Answer:
-2
Step-by-step explanation:
y=mx+b, where m=slope
so move 2x over
y=-2x+4
m=-2
Answer:
y = x + 1.8
Step-by-step explanation:
Answer:
B: congruent to figure A
Step-by-step explanation:
if you reflect figure A across the x-axis the new shape will be the same size and shape as figure A. Which means it is congruent to figure A. So, the answer is B
