Answer:
y = 5.5x - 17
Step-by-step explanation:
(4,5)(2,-6)
- M = ∆y/∆x
- -6-5/2-4
- -11/-2 this is the gradient
- chose any of the point then introduce another point
- (4,5) (x,y) the gradient is -11/-2
- M =∆y/∆x
- y-5/x-4 = -11/-2
- -2(y-5) = -11 ( x -4)
- -2Y + 10 = -11x + 44
- -2Y = -11x + 44 -10
- -2Y = -11x + 34
- divide the while equation by -2
- y = 5.5x + - 17
- y= 5.5x - 17
Answer:
The total cost of purchase of Matt and Natalie are $29.41
Step-by-step explanation:
We are given the following in the question:
Cost of clothing without tax = $27.75
Tax percentage = 6%
Amount of tax on clothing =
Total cost of purchase =
=Total bill without tax + Amount of tax
Thus, the total cost of purchase of Matt and Natalie are $29.41
Answer:
=2 =−2
Step-by-step explanation:
<em>Common factor</em>
16 2 − 64 = 0
16(2 − 4)= 0
Use the sum-product pattern
16(2−4)=0
16(2 + 2 − 2 − 4) = 0
Common factor from the two pairs
16(( 2 + 2) + (−2 − 4)) = 0
16 ( ( + 2 ) − 2 ( + 2 ) ) = 0
Rewrite in factored form
16 ( ( + 2 ) − 2 ( + 2 ) ) = 0
1 6 ( − 2 ) ( + 2 ) = 0
Create separate equations
16 ( − 2 ) ( + 2 ) = 0
− 2 = 0
+ 2 = 0
Solve / Rearrange and isolate the variable to find each solution
= − 2
= 2
Answer:
cool
Step-by-step explanation:
3, because when you both square and square root a value the two cancel each other out.
