What point is on both lines y=12x+3 and y=x+1 <br><br> (no graph)

Mkey [24]

Step-by-step explanation:

by having two equations that have the same point, you can set the two equations equal to each other

y = 12x + 3, y = x + 1

12x + 3 = x + 1

11x = -2

x = -2/11

when you find the the x value, plug it back into either one of the equations

y = x + 1

y = (-2/11) + 1

y = 11/11 - 2/11

y = 9/11

the point (solution):

(-2/11, 9/11)

Select the equation of the line that passes through the point (5, 7) and is perpendicular to the line x = 4.

Vedmedyk [2.9K]

If the line is perpendicular to x = 4, then that means the answer should be y = some number

and since we have the equation going through point (5,7), we look at the y-value since our equation is y=some number and replace the y-value into that equation.

So the correct answer is C. y = 7

Hope that helps :)

Write a linear equation in slope intercept form to model the situation and internet company charges $4.95 per month plus $2.50 f

antoniya [11.8K]

Answer:

it cost $39.95 in a month when you use the internet for 14 hours

Step-by-step explanation:

internet company charges $4.95 per month plus $2.50 for each hour

Let x be the amount of hours internet used

for 1 hour, charge is 2.50

for x hours , charge is 2.50x

To get linear equation we use y=mx+b

m is the slope and b is the fixed cost

fixed cost b= 4.95 and slope m = 2.50

So equation becomes y = 2.50x + 4.95

we need to find the cost y for 14 hours

So we plug in 14 for x and find out y

y = 2.50(14) + 4.95= 39.95

The measure of an angle is twenty-nine times the measure of the supplementary angle. what are the measures of both angles?

riadik2000 [5.3K]

Let's say $x$ is the measure of the first angle and $y$ is measure of the supplement of $x$ . We know that supplementary angles add up to 180°, so $x + y=180$ . We also know that $x = 29y$ . Therefore, $29y+y=180$ . It follows that $y = 6$ , therefore, the first angle is 174° and the second angle is 6°.
