Answer:
3x + 6y
Step-by-step explanation:
CLT
<em><u>9</u></em><em><u>x</u></em><em><u>-</u></em><em><u>7</u></em><em><u>x</u></em><em><u>+</u></em><em><u>x</u></em><em><u>+</u></em><em><u>3</u></em><em><u>y</u></em><em><u>-</u></em><em><u>2</u></em><em><u>y</u></em><em><u>+</u></em><em><u>5</u></em><em><u>y</u></em>
<em><u>3</u></em><em><u>x</u></em><em><u>+</u></em><em><u>6</u></em><em><u>y</u></em>
Logically, he would owe 14 less each week
Let x = # of weeks passed
Algebraic Expression: 141 - 14x =
Week 1: 141 - 14 = 127
Week 2: 141 - 14(2) = 113
Week 3: 141 - 14(3) = 99
etc.....
Hope this helps
Answer:
id say A
Step-by-step explanation:
Answer:
As this value is definite (has an end), it would be considered rational.
Answer:
a = -4
b = 3
c = 6
Step-by-step explanation:
x^2 + 8x = 38
We take the coefficient of the x term
Divide by 2 and then square it
8/2 =4
4^2 = 16
Add 16 to both sides
x^2 +8x + 16 = 38 + 16
x^2 +8x +16 = 54
Take b/2 and use it in the the (x+b/2)^2
(x+4)^2 = 54
Take the square root of each side
sqrt((x+4)^2) = ± sqrt(54)
x+4 = ± sqrt(54)
Subtract 4 from each side
x+4-4 = -4 ± sqrt(54)
x = -4 ± sqrt(54)
Simplify the square root
x = -4 ± sqrt(9*6)
x = -4 ± sqrt(9) sqrt(6)
x = -4 ± 3 sqrt(6)
