What is the answer for "The points (4,r) and (8,-11) lie on a line with slope -3. Find the missing coordinate r."?​

Answer:

y=3[tex](x-4)^{2}[/tex]-47.5

Step-by-step explanation:

I did it in my notebook.

The equation of directrix of the parabola will be x = -4.

Directrix is a straight line distance to which from any point of a conic section is in fixed ratio to the distance from the same point to a focus. The directrix is perpendicular to the axis of symmetry and does not touch the parabola.

We have,

Vertex of parabola = (0, 0),

Focus of the parabola = (4, 0),

Now,

The Equation of directrix is given by y = -a

Where,

The equation of the parabola, [tex]y^2 = 4ax[/tex],

And,

Focus at (a, 0),

i.e. a = 4    (As the given focus is (4, 0))

And,

The axis of the parabola is the positive x − axis.

So,

The equation of the directrix of this parabola,

x + a = 0,

i.e.

x + 4 = 0

⇒

x = -4

Hence, we can say that the equation of directrix of the parabola will be x = -4.

Answer:

1.2 minutes

Step-by-step explanation:

6 divided by 5 = 1.2

To do this, you take the total number of minutes, which is 6, and divide by the number of laps that Lin ran, which was 5.

Answer:

1.2 minutes

Step-by-step explanation:

5 laps/6 minutes = 1 lap/x minutes

To convert the ratio from 5 laps to one laps, 5 was divided by 5. Therefore, to keep the same ratio, 6 must also be divided by 5, making the answer:

1 lap/1.2 minutes

Answer:

12.5 + (16.25 * 1.0716)x ≤ 175

Step-by-step explanation:

The state tax is approximately 7.16%, so it's why I multiplied 16.25 with 1.0716.

Answer:

Step-by-step explanation:

Total points Mario scored = total 1-point free throw + total 2-point field goal + total 3-point field goal.

In 80 attempts 1-point free throw, Mario had 75% success rate. That is, Mario had 80 x 75/100 success

80 x 75/100 = 60

Thus, Mario scored 1 x 60 (since for each success, 1 points is added) points = 60

In 60 attempts 2-point field goal, Mario had 90% success rate. That is, Mario had 60 x 90/100 success

60 x 90/100 = 54

Thus, Mario scored 2 x 54 points (since for each success, 2 points are added) = 108

In 60 attempts 3-point field goal, Mario had 25% success rate. That is, Mario had 60 x 25/100 success

60 x 25/100 = 15

Thus, Mario scored 3 x 15 points (since for each success, 3 points are added) = 45

Therefore, the total points Mario scored = 60 + 108 + 45

= 213

Answer:

(7.46-2.66)/5 do that and you have the answer (I'm lazy)

Step-by-step explanation:

The equation for jj is ($7.46 - $2.66) / 5 and the cost of each bottle of juice is $0.96

The first step to take in order to determine jj, is to determine the total cost of the  5-pack of juice bottles.

Cost of the  5-pack of juice bottles = Total cost before tax - cost of the bag of oranges

Cost of the  5-pack of juice bottles = $7.46 - $2.66 = $4.80

The second step is to determine the cost of each bottle of juice

The cost of each bottle of juice = Cost of the  5-pack of juice bottles / total number of bottles

$4.80 / 5

= $0.96

The previous steps can be summarized into this equation :

The cost of each bottle of juice = (Total cost before tax - cost of the bag of oranges) / total number of bottles

= ($7.46 - $2.66) / 5

= $0.96

Answer:

41 ft 2 in

Step-by-step explanation:

Since the two triangles in question, that means that the triangles have the same proportions. We know that GH = 16 ft 7 in = 199 in (16x12+7) and HN = 6 ft 3 in = 75 in (6x12+3). GH/HN is 199/75. This is the same ratio that GO/AN will have as well. GO is unknown so we will denote it as x and AN = 15 ft 6 in = 186 in (15x12+6). We know that these two fractions are equal. 199/75 = x/186 solving for x, we get x = 493.52 in and converting that into feet we get 41 ft 1.52 in which rounds to 41 ft 2 in.

Answer:

m = -35/49

c = -48

y = -35/49 x - 48

Step-by-step explanation:

Given the coordinate point

(-98, 22), (0, -48)

Slope m = y2-y1/x2-x1

m = -48 - 22/0 -(-98)

m = -70/98

m = -35/49

Substitute m = -35/49 and (0, -48) into the equation y = mx+c

-48 = 0(-35/49) + c

-48 = c

c = -48

Hence the y-intercept is -48

Get the equation

Recall that y = mx+c

y = -35/49 x - 48
