Answer:

x=12

Step-by-step explanation:

142 and 3x+2 are supplementary angles when the lines are parallel

142+ 3x+2 = 180

Combine like terms

144+3x= 180

Subtract 144 from each side

144+3x-144=180-144

3x=36

Divide by 3

3x/3 = 36/3

x =12

How to graph a line that passes through (-1,-7) and has a slope of 4

lana [24]

Answer:

y=4x-3

Step-by-step explanation:

First, write your equation as y=4x+b. Plug in your coordinate to the equation, it should look like this: -7=4(-1)+b. Multiply 4 by -1 to get -4. It should look like this: -7= -4+b. Add 4 to both sides to get your y-intercept of -3. Go back to your original equation and plug in -3 to b. This is your final equation: y=4x-3. Hope this helped!

Mr. West estimated a mass to be 265g, but upon carefully measuring it, found the actual mass to be 240g. What was the percent er

spayn [35]

Answer:

<h3>The answer is 10.42 %</h3>

Step-by-step explanation:

The percentage error of a certain measurement can be found by using the formula

$P(\%) = \frac{error}{actual \: \: number} \times 100\% \\$

From the question

actual mass = 240 g

error = 265 - 240 = 25

So we have

$p(\%) = \frac{25}{240} \times 100 \\ = 10.41666666...$

We have the final answer as
