Step-by-step explanation:
By Intersecting Chords Theorem,
9 * 4x = 8 * (4x + 2).
=> 36x = 32x + 16
=> 4x = 16, x = 4. (2)
(2 - 7z)(2 + 7z)
= (2)^2 - (7z)^2
= 4 - 49z^2
Answer:
$541
Step-by-step explanation:
Given:
The repair bill includes $355 for parts $146 for labor and a sales tax of $40
Question asked :
what is the total amount we owed = ?
Solution:
Total cost of parts to repair = $355
Total cost of labor = $146
Sales tax =$40
By adding all the cost:
Total cost of repair = $355 + $146 + $40
= $541
Therefore, total amount we have to pay = $541
So when you are doing this u will have to make a sentence
Step two- You will have to combined like terms with x
Step three- You will combine like terms with the regular numbers
step 4- you will then divide x by the number
Usually, we use the number line to solve inequalities with the symbols,
<
,
≤
,
>
, and
≥
.(the second and last one was rather hard to find on my keyboard) In order to solve an inequality using the number line, though, just turn
the inequality sign to an equal sign. Then, solve the equation. Next step,
graph the point on the number line (remember to graph as an open circle if the
original inequality was <, or >). The number line should now be
divided into 2 regions, one to the left of the graphed point, and one to the
right of said point.
After that, pick a point in both regions and "test" it, check to see if it satisfies
the inequality when plugged in for the variable. If it does, draw a darker line from the point into that region, with an
arrow at the end. That is the solution to the equation: if one
point in the region satisfies the inequality, the entire region will
satisfy the inequality.
I had to check back in an old textbook to remember all of that. Sorry about the earlier answer. That was rather foolish to do so without actually understanding the question.
