(2,8),(7,8) slope of the line​
aliina [53]

Answer:

The slope of line is 0 given points (2,8)(7,8)

Step-by-step explanation:

We need to find slope of line given points (2,8),(7,8)

The formula used to find slope of line is: Slope=\frac{y_2-y_1}{x_2-x_1}

We are given:

x_1=2, y_1=8, x_2=7 \ and \ y_2=8

Finding slope using formula:

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-8}{7-2}\\Slope=\frac{0}{5}\\Slope=0

So, the slope of line is 0

\int\limits {\pi y^2} \, dy

y = 2 + x^6

y - 2 = x^6

x = (y - 2)^1/6

\pi \int\limits^3_2 {(y - 2)^{1/6}} \, dx

Well, solving this integral

\pi \int\limits^3_2 {(y - 2)^{1/6}} \, dx = 2,69279

Omar ordered his sister a birthday card from a company that randomly selects a card from their inventory. The company has 21 tot
Ksju [112]

Answer:

P = 7

Step-by-step explanation:

We have 21 total cards and out of those 21 cards, 14 of those are birthday cards. So that means that the amount of cards that are not birthday cards is the number of cards subtracted by the number of birthday cards, also shown as 21 - 14. So 21 - 14 = P, so now we solve what 21 - 14 is which is 7, so that means P = 7.

Let me know if you have any questions.

The product of 7 and a number, x, increased by 1 is between 15 and 43. What is the compound inequality that represents the situa
k0ka [10]

Let's assume that number as x

The product of 7 and a number =7x

and then increased by 1  

so, it will become

=7x+1

now, it is between 15 and 43

so, we can write as

15

now, we can solve for x

Since, we have to isolate x

step-1:

Subtract all the  sides by 1

15-1

14

step-2:

Divide all the sides by 7

\frac{14}{7}

2

so, solution is
