Answer:

See attached picture.

Step-by-step explanation:

To graph the line, start at (0,-3) since b = -3 in the equation. This is the y-intercept. Mark this point. From this point, move down 2 units and to the right 1 unit. Mark this new point at (1,-1). Connect the points with a line. See attached picture.

EleoNora [17]

X represent the number of laps Marcy swam, 1 1/4x represent the number of times Toni swam.

20 + 0.80(1 1/4x) + 15 + 0.85x = 257
20 + x + 15 + 0.85x = 257
1.85x + 35 = 257

Required equation is 1.85x + 35 = 257

Which equation represents a line which is parallel to the line y=-4x-8y=−4x−8?

melisa1 [442]

Answer:

Step-by-step explanation:

y = -4x - <u>8</u>

Any equation with an equal slope will be parallel to the line

Example: y = -4x or y = - 4x + 8

As long as the equation has a different y-intercept and equal slope it will be parallel!

kondaur [170]

Answer: Total number of students will be 112.

Step-by-step explanation:

Since we have given that

The ratio of boys to girls in the top 10% of their class at Bixby High School was

$3:5$

So, Let the number of boys be 3x

Let the number of girls be 5x

According to question,

$\frac{3x+6}{5x+2}=\frac{2}{3}\\\\3(3x+6)=2(5x+2)\\\\9x+18=10x+4\\\\18-4=10x-9x\\\\14=x$

So, total number of students will be

$3x+5x=8x\\\\8\times 14=112$

Hence, Total number of students will be 112.
