Answer:
1 and 4 i think they look proportional
Answer:
Only the first graph
Step-by-step explanation:
In order for a equation to be proportional it has to have a straight line (which indicates that it has a constant rate of change.) and it has to go through the origin
If you were to draw a line straight through the ordered pairs of graph 1 it would be a straight line and it would go through the origin (0,0)
therefore graph one would show a proportional relationship
I would really appreciate some help, please!
Lori has $450 in her bank account. She withdraws $20 a month for her gym membership. Construct a linear equation to model Lori’s bank balance for any given month.
Answer:
y=-20x+450
Step-by-step explanation:
Since Lori has 450$ initially, this can be modeled as our y-intercept of our function, or the b in y=mx+b. Since she's withdrawing 20$ a month to pay for the membership, she's losing 20$, which is why the 20 is negative in the equation. Let x be any amount of months, and y will be the balance of Lori's account at that month x.

A circle has a radius of 13 inches.
Which equation can be used to find the diameter of this circle?
d=2π(13)
d=12(13)
d=2(13)
d=132
Answer:
D = 2(13)
Step-by-step explanation:
radius = 1/2 diameter
so you x2 to find diameter
The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours:
A graph titled Motion of a Dragonfly shows Time in hours on the x axis and Distance in miles on the y axis. The scale on the x axis shows number from 0 to 10 at increments of 2, and on the y axis, the numbers are shown from 0 to 200 at increments of 40. A straight line joins the ordered pairs 0, 0 and 2, 40 and 4, 80, and 6, 120
Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed? (1 point)
The dependent variable is distance, the equation is x = 20y, and the dragonfly will travel 360 miles.
The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.
The dependent variable is time, the equation is x = 20y, and the dragonfly will travel 360 miles.
The dependent variable is time, the equation is y = 20x, and the dragonfly will travel 480 miles.
Answer:
(b) distance, y=20x, 480 mi
Step-by-step explanation:
As is often the case, the only self-consistent answer choice is the correct one.
__
The dependent variable is plotted on the y-axis, so is distance.
(x, y) = (2, 40) tells you y = 20x is an appropriate choice of equation.
In 24 hours, the dragonfly will fly y = 20(24) = 480 miles.

Step-by-step explanation:
Mr. Moore drove the first half of his journey at an average speed of 96 km/h for 2 hours. He then drove the remaining half of his journey at an average speed of 80 km/h. How long did Mr. Moore take for the remaining half of his journey?
Answer:
2h 15m
Step-by-step explanation:
If he drove 96 kilometers per hour for the first two hours, then he traveled 192 kilometers in two hours, meaning that the full trip is 384 kilometers.
192/80 = 2.4
Mr. Moore took 2 hours and 15 minutes to finish his trip.

Answer:
SA=736ft²
Step-by-step explanation:
First I like to start with the triangles
[tex]a =2 \frac{1}{2} bh \\ [/tex]
The reason why we would multiply the triangle area by two is because where finding the area of the triangle in the Back and in the front
[tex]a = 2 \frac{1}{2} (12 \times 8) = 96[/tex]
then we go to the rectangles of the left and right
[tex]a = 2bh[/tex]
[tex]a = 2(20 \times 10) = 400[/tex]
again because the numbers for the base and height of the two rectangles are the same we are going to times by two.
Then we going to find the area for the base of the triangular prism, which would be the bottom rectangle
[tex]a = bh[/tex]
there are no same shapes with the same base and height so where not going to multiply by two
[tex]a = 12 \times 20 = 240[/tex]
now we add all the area that we found up
[tex]400 + 96 + 240 = 736[/tex]
now we have 736ft and since where finding SA we square it
SA=736ft²

Answer:
Slope = 4/3
Step-by-step explanation:
Formula for slope-intercept form: y=mx + b
Given: 3y - 4x = -6
Add -4x to the right hand side to isolate out 3y (y).
It should look like this: 3y = 4x -6
Now divide both sides by 3.
You should get: y = 4/3x -2
Since it's asking for slope, your slope is 4/3.

So first off the inequality sign has to be facing the 5 because that is the max amount of money he can spend on breakfast so we can immediately eliminate answer choices G and J
The reason the answer is not F is because your not adding b to 1.25
B is equal to the number of breakfasts Anthony can buy
Each breakfast cost $1.25 so it would be
5 is greater than or equal to 1.25b
Answer:
Step-by-step explanation:
b/c the breakfasts are $1.25 you would multiply how many he buys , by that cost, soo
5 ≥ 1.25 * b
so he can buy 4 breakfasts 1.25 * 4 = 5
this works out fine for the math. but, for one day .. no breakfast :(

Ari borrowed $20000 and paid it back over 6 years. The simple interest rate was 15% annually. How much interest did Ari pay over the six years? Pls explain, and I will make brainliest
Answer:
$18,000
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 15%/100 = 0.15 per year,
then, solving our equation
I = 20000 × 0.15 × 6 = 18000
I = $ 18,000.
The simple interest accumulated
on a principal of $ 20,000.
at a rate of 15% per year
for 6 years is $ 18,000.

1.) Formula for rate of change is (First value of x - Second value of x)/(First value of Y - Second value of Y). So now, all we have to do is plug in the values. (1 - 3)/(0 - 4). After solving this, we get - 1/2.
2.) 1st box is y = 1/2x+5/12
2nd box is y =-4/5x+4
3rd box is -1/2x - 7
3.) Y intercept is the original height of the candle in centimeters. Slope is the change of the height of the candle in centimeters per minute.

Write the equation represented by the graph below.
Answer:
y=3/10x
Step-by-step explanation:
First, use the formula y2-y1/x2-x1. Pick any two points from the line to put into this formula. In this case, I would pick (0,0) and (20,6) cause I'm lazy lol. Plot these points into the formula. It would look like this 6-0/20-0. Simplify this to get 6/20. The GCM of 6 and 20 is 2 so divide 2 in each side to get 3/10. Because the y-intercept is on 0, there is no y-intercept. Therefore, the equation is y=3/10x

The equation of the line passing through points will be; y = 0.3x - 12
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Consider that the graph shows a straight line passing through points (20, 6), (40, 12), etc.
However, only two points (20, 6), (40, 12) are sufficient to obtain the equation of the line.
The equation of the line passing through two points is given by,
y - 6 = 6/20 (x - 20)
So, the equation of the line passing through points will be,
y = 0.3x - 12
Thus, the required equation is y = 0.3x - 12
