Answer:-1
Step-by-step explanation:
It’s all about the work you put in to get your answer you have to subtract
Answer:
1) 6
2) 8/125
3) 5
4) 4/5
Step-by-step explanation:
1) 2x2x2x2x2x2 = 64 then 2^6 = 64
2) (2/5)^3 =8/125
3) 3x(3^4) = 3^5
4) sq rt 16/25 = 4/5
Answer:
10 minutes
Step-by-step explanation:
50 divided by 5= 10
y = (x-5) (x+6)
y = x+6
-- Clear the parentheses in the first one (multiply it out):
y = x² + x - 30
-- Look at the two equations at the same time.
y = x² + x - 30
y = x + 6
Two quantities that are both equal to the same thing (y)
must be equal to each other, so you can write
x² + x - 30 = x + 6
and THAT should be easy to solve.
-- Subtract' x ' from each side:
x² - 30 = 6
-- Add 30 to each side:
x² = 36
-- Square root each side:
x = 6
and
x = -6 .
Those are the x-coordinates of the two solutions to the
original system of equations. We don't even care about
their y-coordinates, or where exactly they are on the graph.
All we need is the x-coordinate of a the mid-point of a line
segment between them.
Do you remember how to find the mid-point of a line segment ?
-- Its x-coordinate is the average of the x-coordinates of the end points.
-- Its y-coordinate is the average of the y-coordinates of the end points.
AND ...
The average of +6 and -6 is zero !
So ... the midpoint of the two solutions is on the y-axis.
Its x-coordinate is zero.
(Choice B)
Answer:
Robin's gross pay=$50,400
Step-by-step explanation:
We are given that Robin has 15% of his gross pay directly into his mutual fund account each month.
If Robin deposited each month =$630
We have to find the gross pay
Let Robin's gross pay =x
15 % of gross pay= 15% of x=
We know that 12 month in a year
Using multiplication property of equality
Using division property of equality
Hence, Robin's gross pay=$50,400
