Solve for x:<br> 4x – 7 = 8x + 33
Lera25 [3.4K]

Answer:

x = 10

Step-by-step explanation:

Hey there!

To solve this question we will use PEMDAS (order of operations)

4x−7=8x+33

Subtract 8x from both sides.

4x−7−8x=33

Combine 4x and −8x to get −4x.

−4x−7=33

Add 7 to both sides.

−4x=33+7

Add 33 and 7 to get 40.

−4x=40

Divide both sides by −4.

x= 40/-4

Divide 40 by −4 to get −10.

x=−10

Hello!

Let O be the center of the sphere, A the tangency point and B the location of the satellite.

m<ABO = 1/2m(b) = 1/2 * 138 = 69

m<OAB = 90

m<AOB = 180 - 90 - 69 = 21

21 * 2 = 42

The answer is 42°

Hope this helps!

Find the integral of 3/sqrt of 1-4x^2
erastovalidia [21]
\int {\frac{3}{\sqrt{1-4x^{2}}}} \, dx
= 3\int {\frac{1}{\sqrt{1-4x^{2}}}} \, dx
= 3\int {\frac{1}{\sqrt{4(\frac{1}{4} - x^{2})}}} \, dx
= \frac{3}{2}\int {\frac{1}{\sqrt{\frac{1}{4} - x^{2}}}}\, dx

= \frac{3}{2}sin^{-1}(2x) + C
