Answer:
0.7125*P
Step-by-step explanation:
The original price of a product is P.
The products are marked down 25%, so the sale price of the products are
75% of P = 0.75*P
Then, in the check out, the store offers a coupon for 5% off, so the sale price will decrease 5%, that is, will be multiplied by 0.95:
Final price = 0.75*P * 0.95 = 0.7125*P
Answer:
A; 8.60
Step-by-step explanation:
![a^{2} +b^{2} = c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3D%20c%5E%7B2%7D)
![7^{2} + 5^{2} = c^{2}](https://tex.z-dn.net/?f=7%5E%7B2%7D%20%2B%205%5E%7B2%7D%20%3D%20c%5E%7B2%7D)
![49+25=c^{2}](https://tex.z-dn.net/?f=49%2B25%3Dc%5E%7B2%7D)
![74=c^{2}](https://tex.z-dn.net/?f=74%3Dc%5E%7B2%7D)
![\sqrt{74} =c](https://tex.z-dn.net/?f=%5Csqrt%7B74%7D%20%3Dc)
8.60 = c
Y=mx+b
slope=m
yint=b
we are given
slope=-2/3
point=(-3,-1)
y=-2/3x+b
input point -3,-
x=-3
y=-1
find b
-1=-2/3(-3)+b
-1=2+b
minus 3
-3=b
y=-2/3x-3
answer is D
<span>Simplifying
4(x + -3) = 7x + 24
Reorder the terms:
4(-3 + x) = 7x + 24
(-3 * 4 + x * 4) = 7x + 24
(-12 + 4x) = 7x + 24
Reorder the terms:
-12 + 4x = 24 + 7x
Solving
-12 + 4x = 24 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
-12 + 4x + -7x = 24 + 7x + -7x
Combine like terms: 4x + -7x = -3x
-12 + -3x = 24 + 7x + -7x
Combine like terms: 7x + -7x = 0
-12 + -3x = 24 + 0
-12 + -3x = 24
Add '12' to each side of the equation.
-12 + 12 + -3x = 24 + 12
Combine like terms:
-12 + 12 = 0
0 + -3x = 24 + 12
-3x = 24 + 12
Combine like terms: 24 + 12 = 36
-3x = 36
Divide each side by '-3'.
x = -12
Simplifying
x = -12</span>
