Answer:

$\Huge\boxed{\mathsf{\frac{1}{26} }}$

Step-by-step explanation:

<em><u>SLOPE FORMULA:</u></em>

$\longrightarrow \displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1} }}$

Y₂=(-15)

Y₁=(-16)

X₂=(-7)

X₁=19

Solve.

$\displaystyle \mathsf{\frac{(-15)-(-16)}{(-7)-19}=\frac{(-15)+16}{(-7)-19}=\frac{1}{-26}=\boxed{\mathsf{\frac{1}{26}} } }}}}$

So, the slope is 1/26.

For what value of x is the expression –4x – 8 equivalent to –9x –1?

Alexeev081 [22]

The value of x where the expression –4x – 8 will be equivalent to –9x –1 will be 7/13.

<h3>How to calculate the value?</h3>

It should be noted that we are simply to find the value of x where the expression –4x – 8 will be equivalent to –9x –1.

This will be:

= +4x - 8 = -9x - 1.

4x + 9x = -1 + 8

13x = 7

Divide

x = 7/13

The value is 7/13.

carlos can write 3 to 4 pages in his journal in 2/3 hour. if he writes for 5 hours, what's a reasonable number of pages he can w

zheka24 [161]

Answer:

23, 24, 25, 26, 27, 28, 29, or 30

22.5 ≤ p ≤ 30

Step-by-step explanation:

So we know that in 2/3 hours, Carlos can write 3 to 4 pages.

First, lets find how many 2/3's are in 5. Lets divide 5 by 2/3.

$\frac{5}{\frac{2}{3}}=7.5$

So there are 7.5 2/3's in 5.

Now, lets assume Carlos writes 4 pages per 2/3 hours consistently throughout that 5 hours. This would yield the maximum amount of pages Carlos can write in 5 hours.

7.5(4) = 30

So the maximum amount of pages Carlos can write in 5 hours is 30.

Now, lets assume Carlos writes 3 pages per 2/3 hours consistently throughout that 5 hours. This would yield the minimum amount of pages Carlos can write in 5 hours.

7.5(3) = 22.5

So the minimum amount of pages Carlos can write in 5 hours is 22.5.

Now we can write the information that we found as an inequality. Lets make p equal to the pages that Carlos can write in 5 hours.

22.5 ≤ p ≤ 30

Any value greater than to equal to 22.5 and less than or equal to 30 would be reasonable.

I hope you find my answer and explanation to be helpful. Happy studying.

The area of the given square pyramid is:

total area = 1,100 inches squared.

<h3 /><h3>How to get the area of the pyramid?</h3>

On the second image, we can see that the pyramid is conformed of a square base and 3 triangles.

To get the surface area of the pyramid, we can just get the area of each of these simpler parts.

The base is a square of 22 in by 22 in, then the area of the base is:

B = (22in)*(22 in) = 484 in^2

For each triangle, the area will be:

A = (base side)*(height)/2

A = (22in)*(14in)/2 = 154 in^2

And we have 4 of these triangles, then the total area of the pyramid will be:

total area = B + 4*A = 484in^2 + 4*(154 in^2) = 1,100 in^2
