Let's apply the formula giving the slope:


m=(y2-y1) /(x2-x1) , let's plug:


m= (8-0) / (3-(-1)) ====> m= 2

Nonamiya [84]

Answer:

The Answer would be option C. 3/4 books per hour

Step-by-step explanation:

You would flip 1/3 to 3/1 which makes it a whole number. then multiply

1/4 and 3.

According to a state law for vehicles traveling on state roads, the maximum total weight of a vehicle and its contents depends o
Alex787 [66]

Inequalities are used to show the relationship between unequal expressions.

The inequalities that represent the maximum weights are:

  • <em>2 axles - </em>x \le 40000<em>.</em>
  • <em>3 axles - </em>x \le 60000<em>.</em>
  • <em>4 axles - </em>x \le 80000<em>.</em>

<em />

Let the maximum weight be represented with x

In inequality, maximum means less than or equal to i.e. \le

<u>(a) 2 axles</u>

The maximum weight, here is 40000.

So, the inequality is:

x \le 40000

<u>(b) 3 axles</u>

The maximum weight, here is 60000.

So, the inequality is:

x \le 60000

<u>(c) 4 axles</u>

The maximum weight, here is 80000.

So, the inequality is:

x \le 80000

How do I correctly solve this?
Gelneren [198K]
<h3>Answer: y = 14</h3>

===================================

Explanation:

The two angles involving x add up to 180 degrees. This is because they are same side interior angles (and because the horizontal lines are parallel)

So,

(angle BCF) + (angle EFC) = 180

(5x - 66) + (2x + 50) = 180

5x - 66 + 2x + 50 = 180

7x - 16 = 180

7x - 16+16 = 180+16 ... add 16 to both sides

7x = 196

7x/7 = 196/7 .... divide both sides by 7

x = 28

This will be used to help find y

Notice how the angles BCF and ACD are vertical angles, therefore they are congruent or the same measure

angle ACD = angle BCF

9y - 52 = 5x - 66

9y - 52 = 5*28 - 66 ..... replace x with 28 (since x = 28)

9y - 52 = 140 - 66

9y - 52 = 74

9y - 52+52 = 74+52 .... add 52 to both sides

9y = 126

9y/9 = 126/9 .... divide both sides by 9

y = 14

Answer:

10.7

Step-by-step explanation:

You set up the proportion like this:

\frac{x}{8} =\frac{4}{3}

When you solve for x you get

x=\frac{32}{3}=10.66666667

x=10.7 rounded to the nearest tenth
