Step by step how to solve 4x+2=5(x+10)​
Shalnov [3]

Answer:

x = -48

Step-by-step explanation:

4x + 2 = 5(x + 10)

expand the 5(x+10)

4x + 2 = 5x + 50

-2 both sides

4x + 2 - 2 = 5x + 50 - 2

simplify

4x = 5x + 48

-5x both sides

4x - 5x = 5x + 48 - 5x

simplify

-x = 48

÷ (-1) both sides

-x ÷ (-1) = 48 ÷ (-1)

simplify

x = -48

The answer is x = -48.

Use a calculator to solve for theta in the given interval
Allushta [10]

Answer:

d. 1.82\: or\:4.46

Step-by-step explanation:

The given trigonometric equation is;

\sec \theta=-4.0545

Recall that;

\cos \theta=\frac{1}{\sec \theta}

\implies \cos \theta=\frac{1}{-4.0545}

\implies \cos \theta=-0.2466

The cosine function is negative in the second and third quadrant.

\theta=\pi-\cos^{-1}(0.2466)\: or\:\pi+\cos^{-1}(0.2466)

\theta=1.82\: or\:4.46
