It is 185 miles to Fort Worth.if Vang drives 2 hours at 65 miles per hour, how far will he be from Fort Worth ?
arsen [322]

Answer:

Answer is 55 miles.

Step-by-step explanation:

65 miles an hour means every hour you cover 65 miles of land. So if it has been 2 hours, you would have crossed 130 miles of land. 185-130=55. Which is why the answer is 55 miles left to go.

Which of the following is an equation of a line parallel to 2x-y=-1?
Simora [160]

Although you didn't provide a list of options to choose from, I hope my explanation will help you  work this out with ease. :)

This equation is in a form known as "standard form." ax+by=c Standard form is commonly used, however for comparing slopes, there is a more efficient equation to use.

Point-slope form (y=mx+b) allows lines' slopes (y) and y-intercepts (b) to be quickly compared and contrasted. Let's put the equation into this form.

2x-y=-1

-2x      -2x

-y = -1 - 2x

*-1      *-1

y= 1 + 2x

Switch pieces around

y= 2x + 1

The slope is 2, the y intercept is 1.

<h2><u>Any line that rises 2 units up for every one unit right and that crosses over the vertical axis at any point other than 1 is your answer.</u></h2>

Which statement is true? A. 2x – 1 = 13 and x = 6 B. 2x – 1 = 13 and x = 7 C. 2x + 1 = 13 and x = 7 D. 2x – 1 = 13 and x = 11
alexandr1967 [171]

Answer:

B. 2x – 1 = 13 and x = 7

Step-by-step explanation:

We are given 4 equations and a solution for each. We have to tell which of the given solution satisfies the given equation.

Option A.

2x -1 = 13 and x = 6

Using this value in the equation, we get:

2(6) -1 = 13

12 - 1 = 13

11 = 13, which is not true. Hence this option is not valid

Option B.

2x - 1 = 13 and x = 7

Using the value in the equation, we get:

2(7) - 1 =13

14 - 1 =13

13 = 13, which is true. Hence this option is valid.

Option C.

2x + 1 =13 and x = 7

Using the value in the equation, we get:

2(7) + 1 = 13

15 = 13, which is not true. So this option is not valid

Option D.

2x - 1 = 13 and x = 11

Using this value in the equation, we get:

2(11) - 1 = 13

21 = 13, which is not true. Hence this option is not valid.
