Answer:

The slope of UV = 4

Step-by-step explanation:

Given the points

Finding the slope of UV

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:1\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-3\right)[/tex]

[tex]m=\frac{-3-1}{-2-\left(-1\right)}[/tex]

[tex]m=4[/tex]

Thus, the slope of UV = 4

Answer:

The equation of the line is:

[tex]y = 4x + 3[/tex]

Step-by-step explanation:

We know that the slope-intercept of line equation is

[tex]y = mx+b[/tex]

Where m is the slope and b is the y-intercept

Given the two points on a line

Finding the slope between (0, 3) and (-2, -5)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-5\right)[/tex]

[tex]m=\frac{-5-3}{-2-0}[/tex]

[tex]m=4[/tex]

We know that the y-intercept can be computed by setting x=0 and determining the corresponding y-value.

From the graph, it is clear:

at x = 0, y = 3

Thus, y-intercept = b = 3

Substituting m = 4 and b = 3 in the slope-intercept form of line equation

[tex]y = mx+b[/tex]

[tex]y = 4x + 3[/tex]

Therefore, the equation of the line is:

[tex]y = 4x + 3[/tex]

Answer:

32 times

Step-by-step explanation:

It's SUPER easy, all you have to do is take that 1/8 and make it into a regular 8. Now all you do is multiply 4 by 8.

I know there's probably some way the teachers taught that's so much harder then it already is, but if you try to look at it from an easier perspective, you'll be a pro!

Try some more so you'll slowly start getting better at them! Anyway I hope this helped!!

Answer:

Step-by-step explanation

8(-1)^4-3(-1)-7= ?

multiply 8 * -1= -8

so -8^4= 4096 that part is done.

now do -3 * -1 and get 3 because two neg. = posit.

so now the question should say

4096+3-7=?

4096+3= 4099-7= 4092

x=4092 i think unless that isnt what you are doing im srry if this is incorrect i tryed and i hope this is correct...again im srry if this is incorrect

Answer:

Step-by-step explanation:

Step-by-step explanation:

Answer:

a. 70%

b. 6 more times

c. subtract from 100% with percentages, subtract from 1 with decimals.

Step-by-step explanation:

a. To find the percentage of red and yellow, skip back the decimal point two times: 0.26 > 26%     0.04 > 4%

Add all of the percentages together to get 70%

b. To find how many times more students said red than yellow, divide yellow from red. It shows you how many times yellow can go into red, giving you the correct answer.

0.26 ÷ 0.04

26 ÷ 4

6

c. 14% + 26% + 40% + 4% = 84%

100% - 84%

16%

(do the same thing with decimals and pick your favorite method)

Answer:

270

Step-by-step explanation:

First, to find how far the car will go in one hour, you do 180 divided by 4. We already know that the car drives at a constant rate. If you do 180 divided by 4, you get 45. Then you multiply 45 by the amount of hours (6) to get 270

Answer:

x = 12

y = 16

Step-by-step explanation:

Use the Pythagoras Theorem on the left triangle.

[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(x)^2=(7.2)^2+(9.6)^2\\x^2=51.84+92.16\\x^2=144\\x=\sqrt{144}\\x=12\\[/tex]

Now use the Pythagoras Theorem on the right triangle.

[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(y)^2=(12.8)^2+(9.6)^2\\y^2=163.84+92.16\\y^2=256\\y=\sqrt{256}\\y=16\\[/tex]

Answer:

So before I answer this question may I ask a doubt, is this data handling?

Answer: 12n + 60

Step-by-step explanation:

So first you have to distribute the 5 in the parentheses.

(5)(n + 12) = 5n + 60

5n + 60 + 7n

Then add like terms.

12n + 60

Each cookie costs 2$.

We can find how much each cookie costs by setting up an equation with x being the amount of cookies, and solve

12x=24     12 cookies equals 24 dollars

x=2            By simplifying and dividing both sides of the equation by 12, we get the variable on its own.

The price of one cookies in the bakery is found as $2.

Each component of a division equation has its own name.

For the given question.

The cost of 12 cookies in a bakery is $24.

The cost of each cookie is same.

To find the price of each cookie divide the total amount by number of cookies.

Price of one cookie = 24/12

Price of one cookie = $2

Thus, the price of one cookies in the bakery is found as $2.
