Rashawn read 25 pages of his book each day until he finished the book. His book was 400 pages long.
Katyanochek1 [597]

The first thing we are going to do for this case is define variables.

We have then:

x: number of days

y: number of pages remaining.

We write the linear equation that models the problem:

y = -25x + 400

The intersection with the vertical axis is:

We evaluate x = 0:

y = -25 (0) + 400\\y = 0 + 400\\y = 400

We get the point:

(x, y) = (0, 400)

The intersection with the horizontal axis is:

We evaluate y = 0:

0 = -25x + 400\\25x = 400

x = \frac{400}{25}\\x = 16

We get the point:

(x, y) = (16, 0)

Answer:

The graph is:

y = -25x + 400

Graph located in the bottom left.

Two students were given the expression shown to simplify.
navik [9.2K]
<h3>The equivalent expression is 6 + 6x</h3>

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

9 - (3 - 6x)

We have to find the equivalent expression

Use the distributive property,

a(b + c) = ab + bc

Therefore, from given expression,

9 - 1(3 - 6x) = 9 - 3 + 6x

Combine the constants, 9 - 3 = 6

9 - 1(3 - 6x) = 6 + 6x

Thus the equivalent expression is 6 + 6x

Please help me with my math
boyakko [2]

Answer:

x = 115

z = 27

Step-by-step explanation:

x + 65 = 180 (same side interior angles)

x = 115

x = 3z +34 (alternate interior angles)

115 = 3z + 34

3z = 81

z = 27
