2(x-8)=7
Distribute on the left side
2x-16=7
Add 16 to both sides
2x=23
Divide both sides by 2
x=11.5
Final answer: The number is 11.5
Answer:
29.1°
Step-by-step explanation:
Given that :
Riser, AB, Opposite = 10 cm
Thread, = AC, Adjacent = 18 cm
Angle of inclination, θ
Using trigonometry :
Tan θ = opposite / Adjacent = AB / AC
Tan θ = 10 / 18
θ = tan^-1(10/18)
θ = 29.055
Hence, angle of inclination is 29.1° (1 decimal place)
Answer:
Or
Step-by-step explanation:
We need to find the slope using the points (-4,5) and (8,8).
The slope formula is given by:
We plug in the values to get:
Parallel lines have the same slope.
Using the point slope formula, the equation is given by:
We substitute the point (-12,-10) to get;
Or
Answer:
6
Step-by-step explanation:
When you multiply two negative numbers, the result becomes posititve
your answer is 30
1^2 (raised to the power of 2) +2 is 3
5^2 +2 is 27
5^2=25
1^2=1
add 27+3=30
