Answer:

x=7/2

Step-by-step explanation:

First, distribute the 9 on the left side

9(3-2x)=2(10-8x)

(9*3)+(9*-2x)= 2(10-8x)

27-18x= 2(10-8x)

Next, distribute the 2 on the right side

27-18x=(2*10)+(2*-8x)

27-18x=20-16x

Now, move all the numbers to one side of the equation, and the variables to the other.

27-18x=20-16x

Add 18x to both sides

27-18x+18x=20-16x+18x

27=20+2x

Subtract 20 from both sides

27-20=20-20+2x

7=2x

Now all the variables are on one side, and the numbers are on the other. x is still not by itself. It is being multiplied by 2. To undo this, divide both sides by 2

7/2=2x/2

7/2=x

Solve the inequality 5u≤8u−21 and write the solution in interval notation

PIT_PIT [208]

Answer:

Step-by-step explanation:

$5u\leq 8u-21$

Subtract 8u from both sides

$-3u\leq -21$

Divide by -3 on both sides

$u\geq 7$

Interval notation: [greater/less than or equal to], (greater or equal to)

Given that sin theta = 1/4, 0→theta→π/2, what<br>. what is the exact value of cos 8?

natali 33 [55]

<h3>Answer: Choice B $\frac{\sqrt{15}}{4}$ </h3>

===========================================================

Work Shown:

Angle theta is between 0 and pi/2, so this angle is in quadrant Q1.

Square both sides of the given equation

$\sin \theta = \frac{1}{4}\\\\\sin^2 \theta = \left(\frac{1}{4}\right)^2\\\\\sin^2 \theta = \frac{1}{16}$

Then use the pythagorean trig identity to get

$\sin^2 \theta + \cos^2 \theta = 1\\\\\cos^2 \theta = 1-\sin^2 \theta\\\\\cos \theta = \sqrt{1-\sin^2 \theta} \ \ \ \text{cosine is positive in Q1}\\\\\cos \theta = \sqrt{1-\frac{1}{16}}\\\\\cos \theta = \sqrt{\frac{16}{16}-\frac{1}{16}}\\\\\cos \theta = \sqrt{\frac{16-1}{16}}\\\\\cos \theta = \sqrt{\frac{15}{16}}\\\\\cos \theta = \frac{\sqrt{15}}{\sqrt{16}}\\\\\cos \theta = \frac{\sqrt{15}}{4}\\\\$
