A coordinate plane with Number of Text Messages on the x-axis and Number of Minutes Used on the y-axis, with points plotted at, (10, 20), (20, 40), (30, 60), and (40, 80).
A prepaid cell phone charges a preset number of minutes to use text messaging. The graph represents y, the number of minutes used for x, the number of text messages sent and received. Is there a direct variation? Which equation represents the relationship?

Yes, y = 2x.
Yes, y = 20x.
No, y = x + 10.
No, y = x + 20.

Answers

Yes y=2x that is the answer

Jada had some dimes and quarters that had a total value of $12.50. The relationship between the number of dimes, d, and the number of quarters, q, can be expressed by the equation 01.d+0.25q= 12.5.

Question 1 - 1 pts
If Jada has 4 quarters, how many dimes does she have?

Question 2 - 1 pts
If Jada has 10 quarters, how many dimes does she have?

Question 3 - 1 pts
Is the number of dimes a function of the number of quarters? If yes, write a rule (that starts with d =...) that you can use to determine the output, d, from a given input, q. If no, explain why not.

Question 4 - 1 pts
If Jada has 25 dimes, how many quarters does she have?

Question 5 - 1 pts
If Jada has 30 dimes, how many quarters does she have?

Question 6 - 1 pts
Is the number of quarters a function of the number of dimes? If yes, write a rule (that starts with q =...) that you can use to determine the output, q, from a given input, d. If no, explain why not.

Answers

1 She has 115 dimes because 0.10*115=11.5 0.25*4=1.00 11.5+1.00=12.5

2 She has 100 dimes because 0.10*100=10.00 and 0.25*10= 2.5 10+2.5=12.5

3 I think they don’t function because quarters are worth more than a dime.

4 She has 40 quarters because 0.25*40=10.00 0.10*25=2.5 10.00+2.5=12.5.

5 She has 38quarters because 0.25*38=9.5 0.10*30=3 9.5+3=12.5

6 Yes they can function because q=dx-12.5

A triangle has A, B, and C located at(-3, 0). (3, 0), and (0, 4), respectively, on the coordinate plane. The medians of (triangle)ABC intersect
at the point with which coordinates? Round each coordinate to the nearest tenth if necessary.

A. (1.5, 2)

B. (-1.5, 2)

C. (0, 1.3)

D. (0, 0)

Answers

Given:

Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).

To find:

The intersection point of all the medians of the triangle ABC.

Solution:

We know that, intersection point of all the medians of a triangle is called centroid.

The formula of centroid is

[tex]Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)[/tex]

Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).

[tex]Centroid=\left(\dfrac{-3+3+0}{3},\dfrac{0+0+4}{3}\right)[/tex]

[tex]Centroid=\left(\dfrac{0}{3},\dfrac{4}{3}\right)[/tex]

[tex]Centroid=\left(0,1.333...\right)[/tex]

Round each coordinate to the nearest tenth.

[tex]Centroid=\left(0,1.3\right)[/tex]

The coordinates of required point are (0,1.3). Therefore, the correct option is C.

(5.-3) and (-1.6)

Answers

Answer:

The slope is [tex]m=-\frac{3}{2}[/tex]

Step-by-step explanation:

The slope point equation is given by:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Here:

The first point is (x1,y1)=(5,-3)

The first point is (x2,y2)=(-1,6)

Then, the slope will be:

[tex]m=\frac{6-(-3)}{-1-5}[/tex]

[tex]m=\frac{9}{-6}[/tex]

[tex]m=-\frac{3}{2}[/tex]

Answer:

y = -3x-2

Step-by-step explanation:

Well, the linear equation of a line is: y = mx + b

Where m is the slope and b is your y-intercept

So, you can just plug the numbers into the equation

m = -3 and b = - 2

y = -3x - 2

x= -14/3 !

hope this helps

Answer:

X= -14/3

Step-by-step explanation:

Subtract \frac{4}{3}

from both sides.

2x=-8-\frac{4}{3}

2x=−8−

2 Simplify -8-\frac{4}{3}−8−

to -\frac{28}{3}−

2x=-\frac{28}{3}

2x=−

3 Divide both sides by 22.

x=-\frac{\frac{28}{3}}{2}

x=−

4 Simplify \frac{\frac{28}{3}}{2}

to \frac{28}{3\times 2}
