Use the given information to write the equation of the line in slope-intercept form: y = mx + b

A: y=-1/2x+4

B: y=-2x+2

C: y=-1/2x+2

D: y=2x+4

Answer:163 bpm

Step-by-step explanation:

The running heart rate of a girl as per linear equation will be 178.7 bpm.

Linear equation is an equation where the highest power of a variable is 1.

As per given data,

The average walking heart rate of eight girls is = (66 + 72 + 74 + 78 + 80 + 84 + 86 + 88)/ 8 = 78.5 bpm.

The average running heart rate of eight girls is = (128 + 136 + 134 + 138 + 142 + 144 + 14 8 + 152)/8 = 1122/8 = 140.25 bpm.

Therefore, for walking heart rate of x, the running heart rate will be (140.25/78.5)x = 1.787x.

Hence, the linear equation between walking heart rate and running heart rate is y = 1.787x.

Now, for walking heart rate of 100 bpm of a girl, the running heart rate will be = 1.787 × 100 bpm = 1787.7 bpm.

Answer:

1. parallel

2. no

Step-by-step explanation:

1. The lines are parallel as they have the same slope and are at different points. Parallel lines means that the 2 lines don't ever meet. It's not the same line because they have different y-intercepts, meaning they are at different points on the graph. They're not intersecting cause like I said, they have the same slope, so they are going up and at the same angle, no way they're going to intersect. And it's not perpendicular as perpendicular lines also require the lines to intersect, which they do not.

2. Plug in (4, 1) into the equation

3x + 2y = 10

3(4) + 2(-1) = 10

12 - 2 = 10

10 = 10, so yeas for this one, now do the other

-2x + y = -7

-2(4) + (-1) = -7

-8 -1 = -7

-9 ≠ -7, so no

Answer:

62 degrees

Step-by-step explanation:

Since it is a straightline, the sum of both angles are 180

So, 180 - 118 = 62

Answer:

240 miles

Step-by-step explanation:

Given that:

Charges offered by Prestige car rentals for renting a midsize vehicle:

Fixed charges = $47

Per mile charges for renting a midsize vehicle = $0.07

Charges offered by Gateway Auto for renting a midsize vehicle:

Fixed charges = $35

Per mile charges for renting a midsize vehicle = $0.12

To find:

Number of miles for which both the companies charge the same price?

Solution:

Let the number of miles for which both the companies will charge the same price = [tex]x[/tex] miles

Charges for one mile by Prestige car rentals = $0.07

Charges for [tex]x[/tex] miles by Prestige car rentals = $0.07[tex]x[/tex]

Total charges by Prestige Car rentals = $47 + $0.07[tex]x[/tex]

Charges for one mile by Gateway Auto = $0.12

Charges for [tex]x[/tex] miles by Gateway Auto = $0.12[tex]x[/tex]

Total charges by Gateway Auto = $35 + $0.12[tex]x[/tex]

As per question statement, the charges are same:

[tex]\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}[/tex]

Multiply the numerator together and the denominators together.

1 x 5 / 6 . 7 = 5/42

42 is not a multiple of 5 so the answer is already in the lowest term.

The answer is 5/42

Answer:

hey you didnt put the graph

Answer:

to find the total number of miles traveled, you have to add the total distance from point L to point M together. 929+ 595 = 1,524 total miles traveled

to find the average miles per hour, you divide the total miles traveled, by the amount of time it took. 1,524 / 3 = 508 miles per hour

Step-by-step explanation:

Answer:

Step-by-step explanation:

LV to Colorado Springs = 595 miles

Colorado Springs to Mil=  929 miles

Total distance =                1524  miles

Average Speed = 1524 miles / 3 hours

Average Speed =  508  miles / hour
