Answer:
a=3, b=3, c=-9, d=-9
Step-by-step explanation:
Expand the left side, Then combine like terms, then set the term on the left side equal to the term on the right with the same power of x (ex. set ax^3=3x^2) Then a=3. Do this for a,b,c, and d
Answer:
Option 2
Step-by-step explanation:
Given
B = (-6,1)
B' = (-3,-2)
Step 1: Substitute the original and translated coordinates into (x,y) => (x+a,y+b)
B(-6,1) => B'(-6+a , 1+b) = B'(-3,-2)
Step 2: Write two equations
-6+a = -3 => a = -3+6 = 3
1+b=-2 => b = -2-1 = -3
Hence, we can conclude that Indira wrote the equations wrong which was her first error.
Therefore, Option 2 is correct ..
Split the second term in 4m^2 + 16m + 15 into two terms
4m^2 + 10m + 6m + 15
Factor out the common terms in the first two terms, then in the last two terms
2m(2m + 5) + 3(2m + 5)
Factor out the common term 2m + 5
(2m + 5)(2m + 3)
The amount of money she spends per year on utility bills for the air conditioner is; D: $176.40
<h3>How to solve algebra word problems? </h3>
We are told that;
Cost of running the air conditioner = 7 hours per day
Cost of running the air conditioner = 21 cents per hour = $0.21 per hr.
She runs it for four months at 7 hours per day. Thus;
Total number of hours for the 4 months = 7 × 30 × 4 = 840 hours
Total cost for the 4 months = $0.21 per hr. × 840 hours = $176.4
