Answer:
a + b = 5
Step-by-step explanation:
To solve this system of equations, we can use a strategy called elimination, which is when we get rid of a variable by adding/subtracting two equations.
Firstly, we want to make sure the absolute value of the coefficients that equal.
Lets eliminate b:
4a + 6b = 24
Multiply both sides by 2:
8a + 12b = 48
We also have:
6a - 12b = -6.
Now lets add that with
8a + 12b = 48
-> 6a + 8a + 12b - 12b = 48 -6
-> 14a = 42
-> a = 3
Now that we know a, lets plug it into one of our original equations:
4(3) + 6b = 24
12 + 6b = 24
6b = 12
b = 2
Finally, add the two values we found:
a+b = 2+3= 5
Answer:
A
Step-by-step explanation:
work out price of each for one bottle
A) $12.60 ÷ 7 = $1.80
B) $10.98 ÷ 6 = $1.83
C) $18.10 ÷ 10 = $1.81
D) $16.38 ÷ 9 = $2.82
we can clearly see that A is the cheapest
Answer:
p^(a-1)
Step-by-step explanation:
The simplified expression can be seen in the picture attached below
As the factors have the same base, we just need to add or substract the exponents
p^(a-3+2) = p^(a-1)
Answer:
A
Step-by-step explanation:
The domain of g(x) is the set of all real numbers. Meaning that all the numbers between the min and max of g would be -7 ≤ x ≤ 7.
