Step-by-step explanation:

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

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

5x + 2 = 3x + 4(2x - 1) please solve step by step

Answers

Answer:

x=1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x+2=3x+4(2x−1)

5x+2=3x+(4)(2x)+(4)(−1)(Distribute)

5x+2=3x+8x+−4

5x+2=(3x+8x)+(−4)(Combine Like Terms)

5x+2=11x+−4

5x+2=11x−4

Step 2: Subtract 11x from both sides.

5x+2−11x=11x−4−11x

−6x+2=−4

Step 3: Subtract 2 from both sides.

−6x+2−2=−4−2

−6x=−6

Step 4: Divide both sides by -6.

−6x

Which equation does not have the same solution as the others?

x/4 = 2
x - 9 = 17
x + 12 = 20
2x = 16

Answers

X/4=2 is x=8
X-9=17 is x=26
X+12=20 is x=8
2x=16 is 8
So its the second one
The correct answer choice is B) x-9=17

8/4=2
8-9=-1
8+12=20
2(8)=16

The second one isn’t correct because 8-9 is not 17, it is -1.

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

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

$6 bag divided by 8lb = $0.75 an apple.

Now, simply subtract

0.80

-0.75

0.05

9.96p − 10.01p ≤ 50, so p ≤ 1
9.96p + 10.01p ≤ 50, so p ≤ 2
9.96 − 10.01p ≤ 50, so p ≤ 3
9.96 + 10.01p ≤ 50, so p ≤ 4
