The slope is
1. Find ordered pairs ( 1 , -4 ) ( 3, 3)
The formula is
M= y2 - y1
_____
X2- X1
2. Replace the numbers
M = 3 - 4.
———
1-3
Subtract
3. You get -1/-2
4. Divide you get 0.5
( but if you need rise and run use -1/-2) rise top run bottom
Slope is 0.5 I think
Hope this helps here a picture of my lesson.

8. Find the value of x so that line mis parallel to line l. (1 p (3x+21)° (4x-7)

dybincka [34]

Answer: The value of x is 28.

Step-by-step explanation:

Since line m is parallel to line l.

So, we assume that

(3x+21)° and (4x-7)° are corresponding angles.

And we know that , corresponding angles formed when a transversal cut the parallel line are equal.

So, they must be equal to each other.

$3x+21=4x-7\\\\21+7=4x-3x\\\\28^\circ=x$

Hence, the value of x is 28.

Consider the following system of equations:

Mashutka [201]

Answer:

Line $y=-2x+3$ intersects line $y=x-5$

Step-by-step explanation:

We are given that

$y=-2x+3$

$y=x-5$

Subtract one equation from other then we get

$-3x+8=0$

$3x=8$

$x=\frac{8}{3}$

Substitute the value of x in first equation then we get

$y=-2(\frac{8}{3})+3=-\frac{16}{3}+3=-\frac{-7}{3}$

Hence, the solution $(\frac{8}{3},-\frac{7}{3})$ is the intersection point of two line equations .

Answer:Line $y=-2x+3$ intersects line $y=x-5$

HELP PLZ DUR 11;59 plz help me

Answer:

Base = 10 cm

Height = 60 cm

Step-by-step explanation:

The formula for the area of a triangle is $area=\frac{1}{2} *b*h$ , where b is the length of the base of the triangle, and h is the length of the height of the triangle.

We know the area is 300, and since the height of the triangle is 6 times its base, we know that $h=6*b$ . We can plug in these values into our formula for the area of a triangle, which gives us the following equation to solve:

$300=\frac{1}{2} *b*(6*b)$

$3b^2=300$

$b=\sqrt{100} =10$

The base of the triangle is 10 centimeters.

Now that we know the base of the triangle, we can plug its value in to the original formula to solve for the height of the triangle, which gives us the following equation:

$300=\frac{1}{2} *10*h$

$5h=300$

$h=60$

The height of the triangle is 60 centimeters.

Your having lunch at Taco Bell. You have your choice of a taco,burrito or Mexican pizza. You can choose between rice and beans.

tino4ka555 [31]

Let T be the taco, B the burrito, MP the mexican pizza, R the rice, and N the beans.

For the main course we can have the first three.

----- T

------ B

-------MP

Each main course comes with the two sides. So an R branch and a B branch go to each of the taco, burrito, or pizza.

-----T---------R or N.

We expand it to

--------T-----------R

---------------------N

And we repeat it for the rest.

Thus, the tree diagram is

----- T --------R

-----------------N

-----B---------R

-----------------N

----MP--------R

----------------N

Members of a junior high basketball team want to brag about how tall they are. First, they measured each player’s height in inch

enyata [817]

First to find the median we need to put the numbers in order from least to greatest.

62, 64, 65, 66, 67, 69, 83

Now take a number from each side

64, 65, 66, 67, 69

Once again.

65, 66, 67

On last time

So the median is 66.

Now to find the mean we must add all the numbers up

64+67+83+65+66+62+69

which equals 476

Now divide 476 by the total number of heights which is 7

476/7=68

So the mean is 68

Answers: Mean; 68 Median; 66
