Write an equation of the form y = mx for the line shown below.

djyliett [7]

Answer:

y = -3x

Step-by-step explanation:

To get slope intercept, you divide both y values by both x values like this

$\frac{y_2 - y_1}{x_2 - x_1}$

In this case this will be $\frac{(-3 - 6)}{(1 - (-2))}$

This will become $\frac{-9}{3}$

Divide those two to get -3, and now you get your slope intercept.

Help :((( please will mark brainless

Answer:

$A_{total} = 25\ ft^2$

Step-by-step explanation:

<u>Step 1: Determine the area of the square</u>

$A = s^2$

$A = (3\ ft)^2$

$A = 9\ ft^2$

<u>Step 2: Split the top figure into a square and triangle</u>

Determine the area of the rectangle

$A = l * w$

$A = (7\ ft - 3\ ft) * (5\ ft - 2\ ft)$

$A = (4\ ft) * (3\ ft)$

$A = 12\ ft^2$

Determine the area of the triangle

$A = \frac{b * h}{2}$

$A = \frac{\frac{7\ ft - 3\ ft}{2} * (5\ ft - 3\ ft)}{2}$

$A=\frac{2\ ft * 2\ ft}{2}$

$A = \frac{4\ ft^2}{2}$

$A = 2\ ft^2$

Since there are two right triangles in the triangle that we have we multiply the area that we got by 2 to get the total area.

$A_{triangle} = 2\ ft^2*2$

$A_{triangle} = 4\ ft^2$

<u>Step 3: Determine the total area</u>

$A_{total} = 9\ ft^2 + 12\ ft^2 + 4\ ft^2$

$A_{total} = 25\ ft^2$

Answer: $A_{total} = 25\ ft^2$

The first two classes of a frequency distribution are 0-9 and 10-19. What is the class width?

likoan [24]

Answer: (a) 9

Step-by-step explanation:

We are given that ,

The first two classes of a frequency distribution are 0-9 and 10-19.

We know that the class width of an class interval is basically the difference between the upper limit and the lower limit of the interval.

For example the class interval for interval 40 - 45 is 5 because 45-40=5.

For the given class interval 0-9 , upper limit= 9

Lower limit =0

⇒ Class width = 9-0= 9

Similarly , for 10-19 , the class width = 19-10=9

Therefore , the class width is 9 .

Hence, the correct answer is (a) 9.

Travis is in a hot air balloon that has just taken off and is now floating 12 meters above its launching point. Shontal is stand

ozzi

Shontal is at a distance of 13 meters from the launching point

Step-by-step explanation:

Step 1 :

Given,

Distance of Travis from the launching point = 12 meters

Distance of Shontal from the launching point = 9 meters

Step 2 :

Let A represent the launching point

B represent the point above the launching point at which the balloon is floating.

C represent the point where Shontal stands on the ground.

The angle made by AB with BC is 90 degrees because the balloon is directly above the launching point

Step 3:

So we have a right angle triangle here, with

AB = 12

BC = 9 and angle ABC = 90 degrees

We need to find out length of AC

Using the theorem of Pythagoras,

AC² = AB² + BC²

AC² = 12² + 9² = 144 + 25 = 169 = 13

Step 4 :

Answer :

Shontal stands at a distance of 13 meters from the launching point
