Answer:
D
Step-by-step explanation:
Given the 2 equations
2x - 3y = 14 → (1)
5x + 3y = 21 → (2)
Adding the 2 equations term by term will eliminate the y - term
(5x + 2x) + (- 3y + 3y) = (14 + 21)
7x = 35 ( divide both sides by 7 )
x = 5 → D
Answer: To find the vertical asymptote(s) of a rational function, simply set the denominator equal to 0 and solve for x. We mus set the denominator equal to 0 and solve: This quadratic can most easily be solved by factoring the trinomial and setting the factors equal to 0. There are vertical asymptotes at .
Step-by-step explanation: that is not an answer but it is an example
Answer:
y =(2/5)x - 1
Step-by-step explanation:
Slope intercept form: y = mx + b
m is slope and b is y-intercept
y =(2/5)x - 1
52.25 x 0.08 = 4.18
So the tax is $4.18, and the total cost is $56.43
2x + y = 350
x + 2y = 475
3x + 3y = 825
x + y = 275
x = 275 - y
(plug back into first equation)
2(275 - y) + y = 350
550 - 2y + y = 350
550 - y = 350
-y =-200 or y = $200 (dog)
therefore, x = $75 (cats)
Check
2(75) + 200 = 350
75 + 400 = 475
HAPPINESS! :)
