1. Answer( -2)
2. Answer is D. 4/3
3. Answer is either A or B
8x+4 = 6x-10
To solve for x you'll want to move all the terms containing x onto the left side of the equation and all the other terms on the right side of the equation.
1. Subtract 6x from both sides.
2x+4 = -10
2. Subtract 4 from both sides.
2x = -14
3. Divide both sides by 2.
x = -7
Answer is:
-7
Answer:
43°
Step-by-step explanation:
supplementary angles sum to 180° , then
second angle + 137° = 180° ( subtract 137° from both sides )
second angle = 43°
Answer:
-114
Step-by-step explanation:
f(x) = -4x^2 +5x
Let x = 6
f(6) = -4(6)^2 +5(6)
= -4(36) +30
- 144+30
= -114
Answer:
19.1 miles
Step-by-step explanation:
The situation given represents a right triangle.
Thus, we would use trigonometric function to find how far north the boat travelled.
Let's represent how far the boat travelled north with "x".
Thus:
Reference angle = 23°
Opposite = x
Adjacent = 45 miles
Apply TOA:
Tan 23° = Opp/Adj
Tan 23° = x/45
Multiply both sides by 45
45 × Tan 23° = x
x = 45 × Tan 23°
x = 19.1013667
x = 19.1 miles (nearest tenth of a mile)
