Answer: 20

Step-by-step explanation: We have to put the given x and y values into the equation, so 2(7) + 2(3)  is the same thing as 14+6, so the answer would be 20.

Answer:

20

Step-by-step explanation:

2x+2y

2(7)+2(3)

14+6

20

Answer:

Train B is traveling faster

Step-by-step explanation:

From the picture, we want to know which train is traveling faster

We can know this by knowing the speed of the trains

Mathematically;

speed = distance/time

Train A

12.5 m in 1 second

speed = 12.5/1 = 12.5 m/s

Train B

100 m in 4 seconds

speed = 100/4 = 25 m/s

So train B is traveling faster

This is because it covered a distance of 100 m in 4 seconds as opposed to train A which covered a distance of 12.5 m

in 1 second

3.2 is the answer. Your welcome

Answer:

369600 feet per hour

Step-by-step explanation:

1m = 5280ft

5280 x 70 = 369600

Answer:

369,600 feet per hour

Step-by-step explanation:

1 mile = 5,280 feet

70 mph (cheetah's speed) x 5,280 feet (feet in 1 mile) = 369,600 feet (cheetah's speed in feet)

The stock market went up 30 1/2 points, then down 90 3/4 points. The total change is equal tor 121 1/4.

Answer:

Cool Down 2:

y = -2x+4

y=1x+1

Part 2:

y = -5/1x +3

y = -6/1x +4

Step-by-step explanation:

Answer:

n=5

Step-by-step explanation:

3/9 = 1/3

so

1/3=n/15

by cross multiplication

15×1 =n×3

15=3n

so

n=15÷3

n=5

Step-by-step explanation:

The intercept is the point where the graph crosses over the y-axis

Answer:

Line s and Line t are parallel.

Step-by-step explanation:

Now, we know that angles 1 and 2 are congruent, because they have the same angle measures. Now, looking at their positions, we can see that they are alternate exterior angles.

By the converse of the Alternate Exterior Angle, (I do not remember exactly how the theorem went) if two lines are cut by a transversal and have congruent alternate exterior angles, then the lines are parallel. Using this theorem, we can find that lines s and t are parallel, because they are cut by a transversal and their alternate exterior angles are congruent.

Answer:

slope of perpendicular line is -1/4

Step-by-step explanation:

slope of standard equation of line that is ax+ by = c is

slope m = -a/b

given equation is

12x – 3y = 81

comparing it with ax+ by = c

a = 12

b = -3

thus

slope of given line = -12/-3 = 4

we also know product of slope of two perpendicular line is -1

let the slope of other line be m

thus,

product of given line line and perpendicular line is -1

4*m = -1

m = -1/4

Thus,

slope of perpendicular line is -1/4

Answer:

y = -1/4x + 4

Step-by-step explanation:

x+4y=28

4y = -x + 28

y = -1/4x + 7

slope m = -1/4

Parallel lines have similar slope so we'll use -1/4 from above and given point (8,2) to find y-intercept.

y = mx +b

2 = -1/4(8) + b

2 = -2 + b

b = 4

Using m and b from above we can now form the new equation of line that is parallel to y = -1/4x + 7.

y = mx + b

y = -1/4x + 4

Answer:

draw a straight line

draw a point and name it A

place your compass at A and expand it to draw an arc

Name point where arch meets the line B

place compass at B and draw arch to pass through the big arc

Draw a line through point of intersection to meet at A

Answer:

9 9/16

Step-by-step explanation:

The first step is to find the LCD of 16 and 2

It is 16, and you can multiply the 6 1/2 by 8 which equals 6 8/16

Then you add

3 1/16 + 6 8/16 is equal to 9 9/16, which is your answer.

Answer:

f=2 and f=11/8

Step-by-step explanation:

Let's solve your equation step-by-step.

f(−4)=−8

Step 1: Simplify both sides of the equation.

−4f=−8

Step 2: Divide both sides by -4.

−4f

−4

=

−8

−4

f=2

Let's solve your equation step-by-step.

f(−8)=−11

Step 1: Simplify both sides of the equation.

−8f=−11

Step 2: Divide both sides by -8.

−8f

−8

=−11/−8

f=11/8

Answer:

length is 15 cm

Step-by-step explanation:

4 * 4 * x = 240

16x=240    : divide by 16 on both sides

x = 15

then to check

15 cm x 4 cm x 4 cm = 240 cm^3
