Answer 1

Answer:

[tex]d = \frac{4 - 3c}{c + 1} [/tex]

Step-by-step explanation:

To make d the subject of formula, we need to rearrange the equation such that we arrive at d= _____.

[tex]c = \frac{4 - d}{d + 3} [/tex]

Remove the fraction by multiplying (d +3) on both sides:

[tex]c(d + 3) = 4 - d[/tex]

Expand:

[tex]cd + 3c = 4 - d[/tex]

Bring all the d terms to one side and move the others to the other side of the equation:

[tex]cd + d = 4 - 3c[/tex]

Factorise d out:

[tex]d(c + 1) = 4 - 3c[/tex]

Divide by (c +1) on both sides:

[tex]d = \frac{4 - 3c}{c + 1} [/tex]

a fitness club opens up with 80 members. Each month the membership increases by 15 members. Which equation represents the relationship between the number of months the club has opened, x, and the total club membership,y?

Answers

Answer:

15x+80=m

Step-by-step explanation:

where x is the number of months and m is the amount of members

Answer/Step-by-step explanation:

y = 15x + 80

The club start with 80. Then each month 15 people are added so the slope is 15. So replace m in the equation y = mx + b with 15.

Next, replace the variable b of y = 15x +b with 80. because the original 80 members is a one time thing that stays there.

Now you have the equation y = 15x + 80. Which correctly describes the fitness club's situation.

x represents the time that one individual act takes.

y represents the time that one group act takes.

Step-by-step explanation:

the first statement says:

"The first show will last 2 hours, and 12 individual acts, and 6 group acts"

He writes this as:

12*x + 6*y = 120.

then x represents the time that individual acts take.

6 represents the time that group acts take.

120 represents the time in minutes (120 min = 2 hours).

The second statement says:

"The final show will last 30 minutes, and it will include the top 4 individual groups, and the top group act."

this is written as:

4*x + 1*y = 30

And it is consistent with the thing we saw above.

At the right, we have time in minutes, 30 minutes.

x represents the time that each individual act needs, and in this case, we have 4 individual acts.

and y represents the time that the group acts need, and we have only one group act in this case.

Then yes, you must agree with your classmate.

Aro diagrams his river rafting trip, estimating the time it will take him to paddle upstream against the current, and then back downstream with the current. His campsite destination is 5.2 miles upstream. Determine how fast Aro can paddle and how fast the river water is moving. Round to the nearest hundredth as needed.
Upstream:
Downstream:
Let x be the speed of Aro’s paddling and let y be the speed of the river.
Upstream: 1.04 = x – y
Downstream: 2.08 = x + y
Aro can paddle at a speed of
miles per hour.
The river’s speed is
miles per hour.

The grass in Jamie's yard grew 16 centimeters in 10 days. It was growing at a constant rate.

Answers

Answer:

1.6 cm

0.625 day

Step-by-step explanation:

We are given that the grass in Jamie's yard grew 16 cm in 10 days.

It was growing at constant rate.

We have to find number of days taken by the grass to grow 1 cm and how many cm  grass grow in one day.

In 10 days , grass grow=16 cm

In 1 day, grass grow=

Grass takes time to grow 16 cm=10 days

Grass takes time to grow 1 cm==0.625 days

Hence, the grass grow 1 cm in 0.625 days and the grass grow 1.6 cm in one day.

Answer:

1.6cm/day

Step-by-step explanation:

Propoertions:

16cm  ⇔  10 days

Y cm  ⇔  1 day

Y = 16*1/10

y = 1.6cm

The constant rate:

1.6 cm / 1 day

Topic: Functions

If you would like to venture further into mathematics, you can check out my Instagram page (learntionary) where I post notes and mathematics tips. Thanks!

Answer: No

Explanation: I think that the least confusing way to do

this problem is to first write down the ordered pairs that

are represented by this mapping diagram.

So we have {(6,3), (-1, 2), (-1, -1), (4, 3)}.

In order for a relation to be a function, each x-coordinate needs

to appear once unless we have a repeated ordered pair.

Since we have the same x-coordinate in two of

our ordered pairs, this relation cannot be a function.

In terms of the mapping diagram, you can see that we have

an x that is paired with two different y's.

So this does not fit the definition of a function which states

that each x must be paired with exactly one y.

A golf ball is hit with an initial velocity of 100 feet per second. The height of the golf ball can be represented by the equation h=100t−16t^2, where t is the time in seconds since the ball was hit and h is the height of the ball in feet. How long will it take for the ball to hit the ground?

Answers

Answer:

6.25 seconds

Step-by-step explanation:

Using the the equation

h = 100t − 16t^2

The ball hits the ground, when h = 0, solving below equation:

100t − 16t^2 = 04t(25 - 4t) = 0t = 0 seconds, this is the starting point when ball was hit25 - 4t = 0 ⇒ 4t = 25 ⇒ t= 25/4 = 6.25 seconds later the ball hits the ground

The equation of the line is y = 2x - 2.

What is the point-slope form of a line?

If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).

The graph of the line is given.

(1)

The line passes through points (2,2) and (6,10).

The slope of the line is:

m = (10 - 2)/(6 - 2)

m = 8/4

m = 2

(2)

The equation of the line with a slope of m =2 and passes through (2,2) is:

y - 2 = 2(x - 2)

y = 2x - 4 + 2

y = 2x - 2         (1)

(3)

The line passes through points (4,b) and (a,8), therefore, from equation (1):

b = 2(4) - 2

b = 6, and

8 = 2a - 2

2a = 10

a = 5

(4)

Substitute x = 0 into equation (1):

y = 2(0) - 2

y = -2

Hence, the equation of the line is y = 2x - 2.
