Answer:
x = 7 and x = -1
Step-by-step explanation:
<u>Step 1: Factor</u>
x^2 - 6x - 7 = 0
(x - 7)(x + 1) = 0
<u>Step 2: Solve for x</u>
(x - 7)(x + 1) = 0
x - 7 = 0 and x + 1 = 0
x - 7 + 7 = 0 + 7 and x + 1 - 1 = 0 - 1
x = 7 and x = -1
Answer: x = 7 and x = -1
With an expression like this, you have to raise all the terms to the 3rd power. So the 5 will become
,
will become
, the 4 will become
and finally, the
becomes
. If you place all of these together in the same fraction, the new answer equivalent to the initial expression is
Answer:
Step-by-step explanation:
You have to find the average of 4, 1, and 9. 4+1+9 is 13/3 is 4.
If 24 of the 60 were saved then the percent saved is
(24/60) x 100
Let's imagine for a second that all 60 was saved, then 100% of the money would be saved. Which makes sense, because
(60/60) x 100 = 100%
So the amount saved dived by the amount earned all times 100 is the percent saved.
The distance from florist to movie theater is about 3.5 km on the same street.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
A book store and a movie theater are 6 kilometers apart. The florist is on the same street, 2.5 kilometers from the theater. Hence:
Distance from book store to movie theater = Distance from book store to florist + Distance from florist to movie theater
Hence:
6 km = 2.5 km + Distance from florist to movie theater
Distance from florist to movie theater = 3.5 km
The distance from florist to movie theater is about 3.5 km on the same street.
