Answer:

18. Slope (m) = 1/2

Y-intercept (b) = -6

19. Slope (m) = 2

Y-intercep (b) = 8

20. y = 1/2 + 6

Step-by-step explanation:

y = mx + b

y - 2x = 8

y = 2x + 8

Answers

Answer:

y= -18

a= -18

Step-by-step explanation:

2y+3 = 3(y+7)

2y+3=3y+21

     -21     -21

2y-18=3y

-2y      -2y

-18=y

Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to its resting place, the cheetah travels an average of 70 mph. If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?
Set up the table as follows. Label the rows “To the River” and “From the River.” Label the columns “Distance,” “Rate,” and “Time (in Hours).” Let t represent the unknown quantity in the problem. Fill in the table.

Answers

Answer:

9.55 minutes

Step-by-step explanation:

x hours to go to the river

0.25-x hours to come back, since 15 minutes is 0.25 hr.

to the river 40 mph * x hours =40x miles

from the river 70 mph (0.25-x) hours=17.5-70x

those two are equal

40x=17.5-70x

110x=17.5

x=17.5/110=0.159 hours

9.55 minutes

-2a + 22 = 22

Answers

What is the multiplicative rate of change of the function?

1/3
2/3
2
9

Answers

Answer:

it is 2/3.

Step-by-step explanation:

please mark as brainliest .

2/3

As x increases by 1
Y decreases by a rate of 2/3.
6x2/3=4
4x2/3=8/3
And so on
To find 2/3, all you need to do is find how y is changing.
First of all, we know that y is decreasing as x increases so the rate is less than 1.
Take y2/y1 to get m or the rate
Ex. 4/6=2/3 which is less than 1!

Hope this helps!!

There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.

Answers

Answer:

Step-by-step explanation:

Given

There are 9 people going on a trip

They purchased coach tickets =$160

first class tickets =$1180

total budget to spend = $4500

Let coach tickets=X

So first class tickets=9-x

160x+1180(9-x)=4500

160+10620-1180x=4500

160x-1180x=4500-10620

-1020x=-6120

X=6120/1020

X=6

So answer

Coach tickets=X=6

First class tickets=(9-x)

=3.

In a class of 42 students, 18 students are in the Math Club, 5 students
are in both the Math Club and the Science Club, and 14 are in neither. How many
students are in the Science Club?

Answers

Answer:

15 maybe?

Step-by-step explanation:

42 - 14 = 28

18 - 5 = 13

28 - 13 = 15

subtract the 14 because it says it is in neither.

Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.

Subtract 13 from the 28 because those 13 are in math and wont be in science also.

Find the slope...........

Answers

First thing to do is find out the coordinates of two points on the graph (I will use the ones that have been marked by the red dots):

Point A: (3, -1)
Point B: (1, 2)

Then we will use the slope formula to work out the slope:

y₂ - y₁ / x₂ - x₁

Substitute in our points:

2 - (-1) / 1 - 3

Then we work out the expression (remember a negative and a negative make a positive!):

3 / -2

Then we check if we can simplify this fraction, which in this case we cannot.

Therefore the slope of that line would be:

3 / -2

(remember to write it as a fraction!)

Answers

Answer:

The ratio of bananas to total fruit is 13:21

Step-by-step explanation:

Since we already know the amount of apples and pears, we can find the total. 13+8=21, and since we know the number of pears, 13, we can say that the ratio is 13:21.

Answer: 13:21

Could someone please find the rate and y-intercept for these two points? (2,2) and (3,4) the help would be greatly appreciated!!

Answers

First use a formula to find rate of change
so a formula most commonly used is (y^1-y^2)/(x^1-x^2)

m= (y^1-y^2)/(x^1-x^2)
=m=(4-2)/(3-2)
=m=2/1
2/1 can also be expressed as just 2 since anything divided by 1 is just itself

Now use the formula y=mx+b to find the y intercept

use either of your two given point to susitute y and x

y=mx+b
Substitute your values
=(4)=(2)(3)+b
Calculate
=4=6+b
Subtract both sides by 6
=-2=b

Therefore the rate of change is 2/1 and the y-intercept is -2
