HELP Write An Equation In Slope-intercept Form For A Line With A Slope Of -2 And A 8 Pointsy-intercept

Answers

Answer 1

Answer:

y=-2x+7

Step-by-step explanation:

slope intercept form is equal to y=mx+c

where y is the y value

x is the x value

m is the gradient

and c is the y intercept

so the equation for this set of values is equal to

y=-2x+7

Answer 2

slope will be the m

and b is the y intercept

y＝mx＋b

y＝-2x＋7

Answer:

I can't draw at the moment but I'll try to teach how as best as I could.

Draw the Cartesian plane (x and y-axis)Locate the point (2, -1). To do this, go to x=2 then go down by 1 unit. Plot it or mark this point by a dot.Then from this dot, go 3 units to the right. After that, go up by 1 unit and mark that with a dot. By this time, you now have 2 dots.Connect them and that's it.

A box of cereal states that there are 87 calories in a 3 4​-cup serving. What is the unit rate for calories per​ cup? How many calories are there in 3 cups of the​ cereal?

Answers

Answer:

3 cups = 348 calories

Step-by-step explanation:

Step 1

Let the calories in one cup be represented as C

Therefore

3/4 x C = 87 calories

C = 87 X 4 / 3 = 116

unit rate is 116 calories per cup.

Step 2- Solving the number of calories in 2 cups

1 cup serving = 116 calories

2 cups servings = 116 x 2= 232 calories

116 x 3 = 348 calories

2250yd

Step-by-step explanation:

There are two picnic sections: a right triangle and a rectangle. The area of a rectangle can be found with A= l * b, meaning the area of the rectangle would be A= 60 * 25 = 1500yd. The right triangle has a base length of 30yd and a perpendicular of 50yd. The area of a right triangle can be found with 0.5bp. The area would be 750yd. 1500 + 750 = 2250yd

Bobby rode his skateboard 4 miles 30 rode her bicycle 10 miles in minutes. Who traveled at a greater average speed? Define an appropriate unit of speed and provide mathematical justification for your answer.

Answers

Answer:

Abelito had the greater average speed

Step-by-step explanation:

Given

Bobby:

[tex]Distance =4\ miles[/tex]

[tex]Time = 30\ minutes[/tex]

Abelito

[tex]Distance = 10\ miles[/tex]

[tex]Time = 48\ minutes[/tex]

Required:

Who had a greater average speed

Average speed (S) is calculated as:

[tex]S = \frac{Distance}{Time}[/tex]

We will make use of mph (miles per hour) as the unit of speed.

For Bobby:

[tex]S_B = \frac{4\ miles}{30\ minutes}[/tex]

Convert minute to hour

[tex]S_B = \frac{4\ miles}{0.5\ hr}[/tex]

[tex]S_B = 8mph[/tex]

For Abelito

[tex]S_A = \frac{10\ miles}{48\ minutes}[/tex]

Convert minute to hour

[tex]S_A = \frac{10\ miles}{0.8\ hr}[/tex]

[tex]S_A = 12.5mph[/tex]

By comparison: 12.5mph > 8mph

Hence: Abelito had the greater average speed

4. David hikes 2 1/4 miles in 1/2 hour. At this rate how long will it take him to walk 1 mile? If he walks for 1 hour,
how far will he have gone? yes

Answers

Answer: 4.50 miles.

Step-by-step explanation:

David hikes 2 1/4 miles in 1/2 hour. To make it easier, we can turn the fractions into decimals.

David hikes 2.25 miles in 0.5 miles.

The ratio of miles hiked to the hours hiked is 2.25 : 0.5. For every 0.5 hours, David hikes 2.25 miles.

To find how many miles David walks in 1 hour, we should multiply the original ratio by 2. 0.5 x 2 = 1, and we need to find how far David walks in 1 hour.

If David hikes 2.25 miles in half an hour, then he will walk 4.50 miles in 1 hour. So the answer is that David will walk 4.50 miles in 1 hour.

A highway inspector needs an estimate of the mean weight of trucks crossing a bridge on the interstate highway system. she selects a random sample of 49 trucks and finds a mean of 15.8 tons with a sample standard deviation of 3.85 tons. the 90 percent confidence interval for the population mean is:

Answers

Answer:

14.90 to 16.70 tons

Step-by-step explanation:

We are given;

Sample size; n = 49

Mean; x¯ = 15.8

Sample standard deviation; s = 3.85

At 90% Confidence interval, z = 1.645

Formula for confidence interval is;

CI = x¯ ± z(s/√n)

Thus;

CI = 15.8 ± 1.645(3.85/√49)

CI = 15.8 ± 0.90

CI = 14.90 to 16.70 tons



An airplane is currently flying at an altitude of 37,000 feet. The airplane is scheduled to land at an airport 100 miles

away. Find the average angle at which the airplane must descend for landing. Round your answer to the nearest

degree.

Answers

Answer:

4degrees

Step-by-step explanation:

Given the following

Height of the airplane = 37000feet

distance covered on landing = 100miles = 100(5280)

distance covered on landing  = 528,000feet

Using the SOH CAH TOA

sin theta = opposite/hyp

sin theta = 37000/528000

sin theta = 37/528

theta = arcsin (37/528)

theta = 4 degrees

Hence average angle at which the airplane must descend for landing is 4degrees

What is a factor of 10

Answers

The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10.

Zoey's dog has a water bowl with a diameter of 6 inches. Sam's
dog has a water bowl with a diameter of 10 inches. What is the
approximate difference in the circumference (distance around)
ut of the two water bowls?

Answers

Answer:

12.56 inches

Step-by-step explanation:

Circumference: C = 2*pi*r

I will be using 3.14 in place of pi

Divide the diameters by 2, so 3 for Zoey and 5 for Sam

Multiply (2*3.14*3) and (2*3.14*5)

For Zoey you get 18.84 and for Sam you get 31.4

31.4-18.84= 12.56 in difference
