Based On The Graph, What Are The Rate Of Change And The Y Intercept Of The Line.O The Rate Of Change

Answers

Answer 1

Answer:

The rate of change is 1/2 and the y-intercept is 1

Step-by-step explanation:

You can calulate the rate of change by picking two points on the graph and using the slope formula

(y2-y1)/(x2-x1)

so in this example you can use the points (2,2) represeting (x1,y1) and (4,3) representing (x2,y2)

When you plug into the slope formula you get:

(3-2)/(4-2) = 1/2 which is the slope.

The y-intercept is where the line intersects the y=axis and can be  seen as the coordinate pair (0, #) where the # is the y intercept. From the graph you can see the y-intercept is 1, but you can aslo solve for the y-intercept using the slope-intercept equation:

y=mx+b

where b is the y-intercept and m is the slope.

so using a slope of 1/2 and a coordinate of (2,2) you get:

y-2=(1/2)(x-2)

y = (1/2x)-1+2

y = (1/2x) + 1

so now the equation is in slope-intecept form and you can see the slope is 1/2 and the y-intercept is 1

Step-by-step explanation:

The first step is to get the given equation to look like the answers provided.

y = - 2/3 x - 1                     multiply by 3

3y = -2x - 3                       add 2x to both sides

3y +2x   = - 3

Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFraction 10 over 50 EndFraction = StartFraction 20 over x EndFraction the same? because both result in the equation 20 x = 500, which simplifies to x = 25 because both result in the equation 20 x = 500, which simplifies to x = 250 because both result in the equation 10 x = 1,000, which simplifies to x = 10 because both result in the equation 10 x = 1,000, which simplifies to x = 100

Answers

Answer:

because both result in the equation 10 x = 1,000, which simplifies to x = 100

Step-by-step explanation:

50 / x = 10/20

Cross product

50 * 20 = x * 10

1000 = 10x

x = 1000 / 10

= 100

10/50 = 20/x

Cross product

10 * x = 50 * 20

10x = 1000

x = 1000/10

= 100

The answer is :

because both result in the equation 10 x = 1,000, which simplifies to x = 100

please help... i'm dying. the table shows the number of calories jane burns while exercising. How many calories would she burn for 29 minutes. Explain.

Answers

I believe it would be 319 as everytime you add 5 to the time it goes up 55. 55 divided by 5 equals 11. So every minute added it 11. Which would mean if we were trying to go from 275 (25 minutes) to the 29 minute mark, we would add 44. 44 plus 275 is 319. I'm not good at explanations but i believe it is 319.

m<ACB is equal to m<ABC because when to split the triangle down the middle and reflect one half you would have the same open shape. So by knowing that, you add 46+46 to get 92. Also knowing a triangle is equal to 180, you would end up subtracting 92 from 180 to get 88.

write an equation for a line through (1,-1) and (2,3)

Answers

Answer:

y = 4x - 5

Step-by-step explanation:

Use the point slope form and add in the ordered pairs [tex]\frac{3 + 1}{2 - 1}[/tex] , and once you solve this it equals [tex]\frac{4}{1}[/tex], or just 4. Now you have the first part of your equation, y = mx + b, but now you have y = 4x + b. To find b, substitute the x and y values of one of the given ordered pairs in for x and y in the equation, and I am using (2,3). The equation now looks like this: 3 = 4(2) + b. Now solve: 3 = 8 + b

Subtract 8 from both sides to get -5 = b. Now you have a full equation: y = 4x -5

On a field trip, there are 8 adults and 24 students. What is the ratio of students to the total number of people on the field trip? 8 to 24 1 to 4 32 to 24 3 to 4

Answers

Answer:

1/4!

Step-by-step explanation:

8 + 24=32

32 ÷ 8 = 4

8x4=32

There is only one 8 so it would be 1/4

Hope this made sense :)

Answer:

The ration is 24:32, or 3:4

Step-by-step explanation:

I know you don't care about an explanation, and just want the answer, but I'll still explain it.

The total people on the trip are the number of kids+the number of adults. We get 32.

Now, the number of kids on the trip is 24 right? The ratio right now is 24:32. We can simplify this dividing the entire thing by 8, so the number isn't as big. Once we do that, we see that our answer is 3:4

What is a system of equations?

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought

Given that, a system of equations, we need to solve them graphically,

The equation are =

4x-3y = 9....(i)

x-3y = 6....(ii)

To solve by graphically, we will first plot the graph,

Finding the coordinates for same,

Equation (i)

4x-3y = 9

Put x = 0,

y = -3

a) (0, -3)

Put x = 3,

y = 1

b) (3, 1)

Equation (ii)

x-3y = 6

Put x = 0,

y = -2

c) (0, -2)

Put x = 3,

y = -1

d) (3, -1)

Therefore, we get the coordinates of the equations, now when we plot the graph, both the lines will intersect at a point and that point will be the solution of the systems of equations,

The lines are intersecting at (1, -1,667).

Hence, the solution of the systems of equations is (1, -1,667).
