Find the slope of y-intercept of the line represented by the table. Please look at the photo

Answers

Answer:

The slope is m= 4 and the y intercept is b= 9

Step-by-step explanation:

The slope is found by using change in y over change in x, or rise over run. From the table, this means, how much does y change for every time x goes up. As you can see, every time x increases by one, y increases by 4. So that´s your slope. The y intercept is when the line crosses the y axis, where x=0. Because you already know the slope, and that when x is one, y is 13, all you have to do is to know that going backwards by one for x means going backwards by 4 for y, and 13-4 is 9.

What is a scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

The Burj Khalifa, a building in Dubai,

United Arab Emirates, is about 828 meters tall.

Brody is making a scale model of this building,

using the scale factor 1:500.

The height of the model = 828 / 500 = 1.656

= 1.7 to the nearest tenth.

Therefore, the model is 1.7 meters tall to the nearest tenth.

2x-.25y < 1 is equal to 2x-1/4y < 1
multiply each side by 4:
8x-y < 4
add y to each side:
8x < 4+y
subtract 4 from each side:
8x-4 < y
rewrite:
y > 8x-4

4x+8y > 4
divide both sides by 8:
1/2x+y > 1/2
subtract -1/2x from each side:
y > -1/2x + 1/2

The Henry family drove 276.5 miles on the family vacation. They used 7.9 gallons of gas. How many miles per gallon of gas did they get on the trip?

Answers

Answer:To solve this problem you would have to write 276.5 over 7.9 and divide the numerator and denominator by 7.9 since you want miles per gallon (it should have a denominator of 1 after you divide). When you do this you will get 35, so the Henry family got 35 miles per gallon of gas on the trip.

Step-by-step explanation:

A line through which two points would be parallel to a line with a slope of 3/4?

a
(0,-2) and (-4,-2)
b
(0,5) and (-4,2)
c
(0,2) and (-4,1)
d
(0,0) and (0,-2)

Answers

Answer:

F. (0, 5) and (-4, 2)

Step-by-step explanation:

We need to calculate the slope of each of the given sets of points until we find the set associated with a slope of 3/4:

F. (0,5) and (-4,2) As we go from (-4, 2) to (0,5), x increases by 4 and y increases by 3, so the slope is m = rise / run = 3/4. This is the line with slope 3/4.

The square on the hypotenuse is qual to the sum of the squares on the other 2 sides, that is

a² + 24² = 26²

a² + 576 = 676 ( subtract 576 from both sides )

a² = 100 ( take the square root of both sides )
