Hello from MrBillDoesMath!
Answer:

Discussion:
34 + 2x = 40 => subtract 34 from both sides
(34-34) + 2x = 40 - 34 => as (34-34) = 0 and 40-34 = 6
2x = 6 => divide both sides by 2
x = 6/2 = 3
Check the answer:
Does 34 + 2x = 40 if x = 3 ?
Does 34 + 2(3) = 40 ?
Does 34 + 6 = 40 ? YES! so the answer checks.
Thank you,
MrB
Answer:
15x + 40
Step-by-step explanation:
5(3x + 8)
Use the distributive property and multiply 5 by 3x and 8
5(3x + 8)
15x + 40
D = distance from finish line
D= 5 - 1/3x
Distance from the finish line is equal to the distance of the start line from the finish line, minus one third of a km times the number of minutes hes been running.
using given variables; D= 5 - 1/3*3
D=5-3/3
D=5-1
D=4
ANSWER
EXPLANATION
The given angle is 870°.
870°-360°-360°=150°
This means that:
870° is coterminal with 150°, hence its terminal side is in the second quadrant.
It makes an acute angle of 30° with the x-axis.
Note that cotangent is negative in the second quadrant,
Hence,
The first option is correct.
Answer:
<h3>
f[g(x)] = 4x²+6x-3</h3>
Step-by-step explanation:
- f[g(x)]=(2x)²+3(2x)-3...substitute the values of g(x) into the function f(x)
- f[g(x)]=4x²+6x-3...simplified
