What is the slope of the line?<br> y + 1 = 3(2x - 4)

Alexeev081 [22]

Answer: 6

Step-by-step explanation:

Let's start by getting the equation to slope intercept form

First simplify

$y + 1 = 3(2x - 4)\\\\y+1=6x-12$

Then get y by itself

$y+1-1=6x-12-1\\y=6x-13$

In slope intercept form y=mx+b, m is the slope

In this case the slope is 6

What is the value of x ? (Make sure you give the value of x !!!!)

DochEvi [55]

Answer:

The value of x is 20 degrees.

Step-by-step explanation:

The three angles of a triangle must equal 180 degrees.

100 + 40 + 2x = 140 + 2x

180 - 140 = 40 (goal)

2(x) = 40

2(20) = 40

A) 20 degrees

The gas tank of a 2013 Honda Accord holds 17.2 gallons. How many pounds of carbon dioxide are produced by burning an entire tank

cricket20 [7]

One gallon of gasoline (6.3 lbs.) produces about 20 lbs. of carbon dioxide. This may seem weird and untrue, however, most of that weight comes from the oxygen in the air. Following the math on this means that we multiply 17.2 gallons of gas by 20 lbs. of co2 per gallon of gas burned.
This gives us the answer of 344 lbs. of carbon dioxide burned per tank of gas. (From a 2013 Honda Accord)

Alice works at a health care facility. She has measured the hemoglobin levels of 200 people. The data follows a normal distribut

rewona [7]

Since the data follows a normal distribution, the 68-95-97 rule can be used to describe the number of people falling under N standard deviations from the mean. Since the standard deviation is 1, hemoglobin levels of 13 -15 g/dL contains 68% of the sample, or 136 people. This means the 32 people have less than 13 g/dL and 32 people have more than 15 g/dL.

Mustafa contributes 11% of his $67,200 annual salary to his 401(k) plan. What is his pretax income?

Juli2301 [7.4K]

11% of $67,200.
We need to keep in mind that some words and numbers here aren't important, like 401(k) plan.
So what is 11% of $67,200?

$\frac{11}{100} * $67,200
$

$11*$672$

$7392

Hope this helps!
