Answer:

y= $\frac{25}{11}$ x

coordinates: (11,25) (22,50) (33,75)

Step-by-step explanation:

I dont really understand this question but I input the equation into desmos (a graphing website) and that is the equation I got

A, B, and C are collinear, and B is between A and C. The ratio of AB to BC is 3 : 1.

S_A_V [24]

Coordinates of point C: (1,-1)

Step-by-step explanation:

In this problem, A, B and C are collinear, and B is between A and C.

The ratio AB : BC is 3 : 1.

This means that we can write the following two equations:

$x_B-x_A = 3(x_C-x_B)\\y_B-y_A=3(y_X-y_B)$

where:

$(x_A,y_A)=(-7,3)$ are the coordinates of point A

$(x_B,y_B)=(-1,0)$ are the coordinates of point B

$(x_C,y_C)$ are the coordinates of point C

Solving the equation for $x_C$ ,

$x_C = x_B + \frac{x_B-x_A}{3}=-1+\frac{-1-(-7)}{3}=1$

Solving the equation for $y_C$ ,

$y_C=y_B + \frac{y_B-y_A}{3}=0+\frac{0-3}{3}=-1$

So, the coordinates of point C are

$C(-1,1)$

Solve for

Varvara68 [4.7K]

Answer:

t = 1, but please check to see if I correctly interpreted your formatting.

Step-by-step explanation:

The format of the question is too confusing.

I'll assume this is the equation to be solved:

16−2t=t+9+4t

16−2t=t+9+4t

16-9 = t + 2t + 4t

7 = 7t

t = 1

What would be the correlation coefficient (r) of the following scatter plot?

luda_lava [24]

Answer:

-0.89 (i think)

Step-by-step explanation:

Since the graph seems to be going downwards from the right, it has a negative correlation. And since the data seems to be pretty close together, the correlation must be strong. That narrows the answer down to -0.89

If its wrong then i'm not a smart person, and it's -0.15

-13x - 8 = 5 - 8x -3

kramer

Answer:

x = -2

Step-by-step explanation:

$-13x - 8 = 5 - 8x - 3 \\\\-13x + 8x = 5 - 3 + 8 \\\\-5x = 10 \\\\x = \frac{-10}{5} = -2$
