Hey there! :)
Answer:
A. x = 5.
Step-by-step explanation:
Starting with:
4x + 1 = 21
Subtract 1 from both sides:
4x + 1 - 1 = 21 - 1
4x = 20
Divide both sides by 4:
4x/4 = 20/4
x = 5.
Answer:
4x + 107 = 180
Step-by-step explanation:
105 + 4x + 2 = 180
Hello
<span>an equation for the line in point-slope form and general form is :
y = ax+b a : </span>slope ; the <span>Passing through (x' ; y')
</span>y' = ax'+b
y-y' =a(x-x') and : x' =8 y' = -4
calculate a :
let : y = ax+b .....(D)
....(D') y = (1/5)x+4
.(D) perpendicular to(D') : slope (D) × slope (D') = -1
slope (D') = 1/5
slop(D)×(1/5) = -1
slope (D) = -5
equation for the line : y-y' =a(x-x')
y+4 =(-5) (x-8)
Answer:
15/8
Step-by-step explanation:
The formula for tangent of an angle is the ratio of the opposite side length to the adjacent side length in relation to the angle.
In this case,side OQ is opposite to ∠ P and side QP is the adjacent side to ∠ P
tan ∠ P=15/8
