Answer:
4
Step-by-step explanation:
Whatever you multiply or divide to the numerator, you do to he denominator.
Here, 12 was divided by 4 to obtain 3 in the other fraction. So, the missing number has to be 16 divided by 4, which gives 4
Answer:
-2x^2 +16x -8
Step-by-step explanation:
Oh s-
Like terms i guess Same variable you can substract. Remember you only substract from 1 number not from all.
-2x^2 stays the same as there is no like term
9x - (-7x)
-2 - (6)
-2x^2 + 9x+ 7x -2-6
-2x^2 +16x -8
Total cost of books was 15 + 10 or 25. With the 50 % discount on the $10 book, the total is now $20. The total cost was reduced by (B) 20%.
$5 off the $25 price is a 20% discount.
Answer:
y =

+
Explanation:The slope-intercept form of the equation has the following formula:y = mx + c
where:
m is the slope
c is the y-intercept
The given is:17x + 15y = 5
To put it in the slope-intercept formula, we should isolate the y as follows:17x + 15y = 5
15y = -17x + 5
y = (-17/15) x + (5/15)
y =

+

where:
m is the slope = -17/15
c is the y-intercept = 1/3
Hope this helps :)
