Answer:
3
Step-by-step explanation:
The goal is to get the x to be on one side of the equation on its own.
-6x = -18
To get rid of the -6, we would have to do the opposite of what it's doing in the equation - in this case, we would divide, as it's the opposite of multiplying.
What we do to one side of the equation, we have to do to the other.
-6x/-6 = x
-18/-6 = 3
x = 3
Hope that makes sense!
The sale price would be $7.70. the sale is 30%off, so the discount would be o.3 x 11. The sale price itself would be 0.7 x 11. Therefore, 0.7x11 is $7.70 and that is the sale price
Those lengths will NOT form a triangle.
According to the triangle inequality theorem, the longest side has to be LESS than the sum of the other 2 sides.
- f (x) = 3x² + x
- Find f (-5).
Given,
Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.
So,
RS = 6
TR = 4.5
Find TS.
R--------------T----------------S
TS = RS - TR
TS = 6 - 4.5
TS = 1.5
