Replace x with 5 in each equation then subtract:
f(x) = 2(5)^2 - 4(5) = 30
g(x) = 5-2(5) = -5
f(x) - g(x) = 30 - - 5 = 30 +5 = 35
The answer is C. 35
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 5y = 9 → (1)
3x + 4y = 2 → (2)
Multiplying (1) by 4 and (2) by 5 and adding the result will eliminate the y- term
8x - 20y = 36 → (3)
15x + 20y = 10 → (4)
Add (3) and (4) term by term to eliminate y
23x + 0 = 46
23x = 46 ( divide both sides by 23 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (2)
3(2) + 4y = 2
6 + 4y = 2 ( subtract 6 from both sides )
4y = - 4 ( divide both sides by 4 )
y = - 1
solution is (2, - 1 )
Answer:

Step-by-step explanation:
why? bc 110/2.75 is 40
35. It doesn’t specify what type of triangle but if it’s referring to a right triangle it would be 10 if the missing side is the hypotenuse.
If not then it can also be 6 or 8 if it’s an isosceles triangle. I seen a lot of your questions and they don’t seem to have a good clarification of what they mean exactly and I’m an honors pre cal student
