Answer:
y=1.8x-9
Step-by-step explanation:
if they are intercepts so the x/y will be zero, so in y intetceot the x is zero, and in the x itercept the y is zero.
0,-9
5,0
we calculate the slooe / rise
-9-0/0-5 = 1.8
we then use this formula
y-y1=rise(x-x1)
y-0=1.8(x-5)
y=1.8x-9
Answer:
D.
Step-by-step explanation:
The area is the product of 2 adjacent sides:
Area = (5x - 3y)(5x - 3y) as the sides of a square are all equal.
= 5x(5x - 3y) - 3y(5x - 3y)
= 25x^2 - 15xy - 15xy + 9y^2
= 25x^2 - 30xy + 9y^2.
Answer:
90%
Explanation: 27/30 ÷ 3 = 9/10
9/10 ⇒ 9 x 10 = 90%
Answer:
$22.43
Explanation:
We can start by finding the amount that they should tip. The total bill is $78, so we should take 15% of 78 and add it to the total.
0.15 * 78 = 11.7
78 + 11.7 = 89.7
This means that the total cost of the bill, with a tip, is $89.70.
Since there are 4 people, we have to split this total into 4 if they all want to pay equally.
89.70 / 4 = 22.425 = $22.43 !
Hope this helps
Answer:
x^2 + 8x + 16
Step-by-step explanation:
Given length of square x + 4.
Area of square with side S is given by 
.
Therefore are of square with side x + 4 is given by 
Area of square = 
Thus, x2 + 8x + 16 expression represents the area of a fabric square.
