Answer: 11
Step-by-step explanation: write the equation.
2(x+4)=30
Divide by 2
x+4=15
Subtract 4
x=11

Answer:
347.037461955
Step-by-step explanation:
If you are taking the square root of 120,435. I would just put it into a calculator.
(x , y) = (7, - 1)
2x + 3y = 11 → (1)
3x + 3y = 18 → (2)
subtracting (1) from (2) term by term eliminates the y- term
(3x - 2x) + (3y - 3y) = (18 - 11)
x + 0 = 7 ⇒ x = 7
substitute x = 7 into either of the 2 equations and solve for y
(1) → (2 × 7) + 3y = 11
14 + 3y = 11
subtract 14 from both sides
3y = 11 - 14 = - 3
divide both sides by 3
= - 1
solution is (7 , -1)
Answer:
- a) 6
- b) 3t² - 17t + 28
- c) 3t² - 5t - 2
Step-by-step explanation:
<u>Given function:</u>
a) g(2)
- g(2) = 3*2² - 5*2 + 4 =
- 3*4 - 10 + 4 =
- 12 - 6 =
- 6
b) g(t - 2)
- g(t - 2) = 3(t - 2)² - 5(t - 2) + 4 =
- 3(t² - 4t + 4) - 5t + 10 + 4 =
- 3t² - 12t + 12 - 5t + 16 =
- 3t² - 17t + 28
c) g(t) - g(2)
- g(t) - g(2) = 3t² - 5t + 4 - 6 =
- 3t² - 5t - 2
