Answer:
The Answer is B
Ive hade this test before
Answer:
The distance formula uses the coordinates of points and the Pythagorean Theorem to calculate the distance between points. If A and B form the hypotenuse of a right triangle, then the length of AB can be found using this formula, leg2 + leg2 = hypotenuse2 (or you can use A squared + B squared = C squared)

Answer:
<u>Marcelino will have $7.50: his costs are more than his profits. </u>
Step-by-step explanation:
22.50 + 7.50 + 15.00
In total Marcelino spent $45 to make these balloons.
He wants to sell each balloon for $1.25.
If he sells the 30 balloons he bought for $1.25 he will make:
30 * 1.25 = $37.50... okay he made some money, BUT he spent $45 dollars for the items.
45 - 37.50 = $7.50, Marcelino made no profit... he still needs to make $7.50 to pay off his own costs.

Answer:
F (-8, -1)
Step-by-step explanation:
We can solve the system using substitution.
From the second equation
x-6y= -2
x= -2 + 6y
This value of x substitute into 1st equation
-4x+5y=27
-4(-2+6y)+5y=27
8-24y+5y =27
- 19y = 19
y= -1
x= -2 + 6y, y= - 1
x= -2 +6(-1)= -8
x= - 8
x= -8, y= -1
(-8, -1)
