Answer:
8x + 5y + 4
Step-by-step explanation:
Rather than looking for a definite answer for both x and y, you are only going to combine like terms. Simply add x + x and y + y and any coefficients left such as the 2 2’s left without variables. Once all like terms are combined with another, you are finished!
Hope this helped!
Answer: 3x-180
Step-by-step explanation:
Given: Expression for Revenue =
Expression for Cost =
If profit is the difference between the revenue and the cost then the expression for profit will be:
Profit = Revenue - cost
Hence, the expression represents the profit is 3x-180 .
A restricted value is a value that will make the fraction undefined, and thus will make it impossible to exist.
Restricted values can exist in two forms: asymptotes and holes.
By simplifying all sides of this expression, we can find the restricted values.
After finding factors, and then cancelling like factors, keeping in mind the original factors in the denominator, we can find three restrictions:
1, 2, and -2.
Answer:
(5, )
Step-by-step explanation:
Given the 2 equations
5x + 7y = 40 → (1)
3x - 7y = 0 → (2)
Adding the 2 equations term by term will eliminate the y- term
8x + 0 = 40
8x = 40 ( divide both sides by 8 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (1)
5(5) + 7y = 40
25 + 7y = 40 ( subtract 25 from both sides )
7y = 15 ( divide both sides by 7 )
y =
solution is (5, )
