Given -10x-2y=16 prove y=-5x-8
Answer:
y doesn't equal -5x-8
Step-by-step explanation:
-10x - 2 (-5x-8) = 16
-10x + 10x +32 =16
32=16? wrong
solve for x
x-2=-5
help anyone?
Answer:
x = -3
Step-by-step explanation:
Note the equal sign, what you do to one side of the equation, you do to the other. Isolate the variable, x.
Add 2 to both sides of the equation:
x - 2 (+2) = -5 (+2)
x = -5 + 2
x = -3
x = -3 is your answer.
~
Answer:
x=-3
Step-by-step explanation:
x-2=5
add 2 to both sides
x-2+2=-5+2
=x=-3
Anser is x =-3

Answer:
45/28
Step-by-step explanation:
Hey There!
They want us to find the tangent of R
Remember in sohcahTOA
t - tangent
o - opposite
a - adjacent
meaning that
[tex]tan = \frac{opposite}{adjacent}[/tex]
The opposite of angle r is 45
the adjacent of angle r is 28
so [tex]tanR=\frac{45}{28}[/tex]

Eric and his two sister shared amount of money in ratio2:7 respectively. If Eric had 300.00 and the remaining amount shared equally among the sister.How much did each sister get.
Answer:
The equal amount is 525 .
Step-by-step explanation:
Given that,
Eric and his two sister shared amount of money in ratio2:7 respectively.
Amount with Eric = 300
It means,
2x = 300
x = 150
So,
7x = 7(150)
= 1050
As the remaining amount shared equally among the sister. So, the equal amount is 525 .
Simplify: a(8 + 2b - 6)

Work out the number of sides of each polygon
Answer: write this:)
Step-by-step explanation:Subtract the interior angle from 180. For example, if the interior angle was 165, subtracting it from 180 would yield 15. Divide 360 by the difference of the angle and 180 degrees. For the example, 360 divided by 15 equals 24, which is the number of sides of the polygon.
