Answer:
x=12 ; y=8
Step-by-step explanation:
8x+13=11x-23(2 opposite side of a parallelogram is equal)
move the x terms to the left side.
8x-11x=-23-13
-3x=-36
3x=36
x=12
2y+12=4y-4(2 opposite side of a parallelogram is equal)
move the y terms to the left side
2y-4y=-4-12
-2y=-16
2y=16
y=8
Answer:
37
Step-by-step explanation:
37+38+39
To determine the minimum amount that Marian should pay for her credit card, multiply the new balance on her credit card with the percentage given. This is shown below.
m = ($148.73) x 0.12 = $17.8476
Thus, Marian's minimum payment is approximately $17.85.
Answer:
y = 0, y =
, y = 7
Step-by-step explanation:
Factor out
from each term
( 3
- 22
+ 7) = 0 , that is
(3y² - 22y + 7) = 0 ← factor the quadratic
Consider the factors of the product of the coefficient of the y² term and the constant term which sum to give the coefficient of the y- term
product = 3 × 7 = 21 and sum = - 22
The factors are - 21 and - 1
Use these factors to split the y- term
3y² - 21y - y + 7 ( factor the first/second and third/fourth terms )
3y(y - 7) - 1 (y - 7) ← factor out (y - 7) from each term
(y - 7)(3y - 1)
Then
(y - 7)(3y - 1) = 0
Equate each factor to zero and solve for y
= 0 ⇒ y = 0
3y - 1 = 0 ⇒ 3y = 1 ⇒ y = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
y - 7 = 0 ⇒ y = 7
The right answer for the question that is being asked and shown above is that: "602 − 402 = (3600 + 1600)(3600 − 1600) = 10,400,000" The equation that shows 602 − 402 being evaluated using the difference of squares method is that <span>602 − 402 = (3600 + 1600)(3600 − 1600) = 10,400,000</span>
