Answer:

40 degrees

Step-by-step explanation:

All the angels of a triangle are equivalent to 180 degrees.

180 - (61 + 79) = 40 degrees

Answer:

x+61+79=180 { being angles of a triangle}

or,x+140=180

or, x= 180-140

hence the value of x=40

Please someone help! You have to make this word problem into an inequality.
labwork [276]

Answer:

the theater needs to sell at least 100 tickets

Step-by-step explanation:

wants to make at least $1000 and they already have $50, so you take the $9.50 per ticket and add that to the $50.

$1000=$9.50t+$50

1000/50=9.5t

950=9.5t

950/9.5=t

t=100

Find the slope of the line.
Anika [276]

The equation for working out the slope of a linear line is: \frac{y_2 - y_1}{x_2 - x_1}, where x and y are the coordinate pairs.

So just pick two of the purple dots on the graph and fill in the equation.

I'll pick the dot that's (-4, 1) and (4, -7).

Now I just do \frac{7 - 1}{4 - -4}, which is just \frac{3}{4} when simplified.

I WILL MARK YOU BRAINLYEST if you answer all of my problems !!!!!!!!!!!
Romashka [77]

First, let's convert each line to slope-intercept form to better see the slopes.

Isolate the y variable for each equation.

2x + 6y = -12

Subtract 2x from both sides.

6y = -12 - 2x

Divide both sides by 6.

y = -2 - 1/3x

Rearrange.

y = -1/3x - 2


Line b:

2y = 3x - 10

Divide both sides by 2.

y = 1.5x - 5


Line c:

3x - 2y = -4

Add 2y to both sides.

3x = -4 + 2y

Add 4 to both sides.

2y = 3x + 4

Divide both sides by 2.

y = 1.5x + 2


Now, let's compare our new equations:

Line a: y = -1/3x - 2

Line b: y = 1.5x - 5

Line c: y = 1.5x + 2

Now, the rule for parallel and perpendicular lines is as follows:

For two lines to be parallel, they must have equal slopes.

For two lines to be perpendicular, one must have the negative reciprocal of the other.

In this case, line b and c are parallel, and they have the same slope, but different y-intercepts.

However, none of the lines are perpendicular, as -1/3x is not the negative reciprocal of 1.5x, or 3/2x.

<h3><u>B and C are parallel, no perpendicular lines.</u></h3>
