Answer:

  y = 7x +10

Step-by-step explanation:

Given a y-intercept of 10 and a slope of 7, you want the equation of the line in slope-intercept form.

The slope-intercept form equation of a line is ...

  y = mx +b . . . . . . . where m is the slope, and b is the y-intercept

You are given a slope of 7 (m=7) and a y-intercept of 10 (b=10), so the equation is ...

  y = 7x +10

Answer:

[tex]C = 0.10n[/tex]

Step-by-step explanation:

If you study the graph you will see that there is no cost for producing zero gadgets. Cost = $0

For 100 gadgets the cost is $10

For 200 gadgets the cost is $20

etc

So the cost in $ is 1/10 times the number of gadgets

For 1 gadget, it costs [tex]\$\dfrac{1}{10}[/tex] or $0.10

For n gadgets it should cost $[tex]0.1n[/tex] same as [tex]\$\dfrac{n}{10}[/tex]

Mathematically speaking the graph represents the equation of a straight line which is of the form

y = mx + b

where y represents the vertical axis and x the horizontal axis

The variable m represents the slope of the line which is the increase of y for every unit increase in x.

The slope, m can be determined by using the formula [tex]\displaystyle \dfrac{y2-y1}{x2-x1}[/tex] where x1, y1 and x2, y2 are two points on the graph

This is also called rise/run

b is called the y-intercept and it represents the value of y where the line crosses the vertical axis

The difference here is that instead of y, we are using C as the variable for the vertical(y) axis and n as the variable for the horizontal(x) axis

So we get the modified equation as
C = m·n + b

We can see that when n = 0, C = 0 so b = 0 because the vertical intercept is zero

To calculate m, take any two points on the line

I choose (0, 0) and (100,10)

[tex]\rm Slope \;m = \dfrac{10-0}{100-0} = \dfrac{10}{100} = \dfrac{1}{10} = 0.10\\\\[/tex]

This means that for every gadget produced the cost will increase by $0.10

The equation becomes C = 0.10n + b and since b is 0 we get

[tex]C = 0.10n[/tex]

slope intercept form is: y = mx + b

where: m = slope and b = y-intercept.

slope = 5 and y-intercept = 5

y = 5x + 5

1x+5

Step-by-step explanation:

the rate of change or slope is the factor of x, when we have the function in the form y = ...

so, it is 2.

that means y changes by 2 whenever x changes by 1.

Answer:

Step-by-step explanation:

a is correct

The model of the exponential functions is written as

21:

f(x) = 50(0.9)ˣ

average rate of change

22:

f(x) = 25(0.8)ˣ

average rate of change

Considering the given problem,  f(x) = a(b)^x

the initial value = a

the base = b

the exponents = x

21.

Initial value: 50

Decay factor: 0.9

1 ≤ x ≤ 4 and

5 ≤ x ≤ 8

x = 1

f(x) = 50(0.9)^1

f(x) = 45

x = 4

f(x) = 50(0.9)^1

f(x) = 32.805

average rate of change for x = 1 and x = 4

average rate of change = (32.805 - 45) / (4 - 1)

average rate of change = -4.065

average rate of change for x = 5 and x = 8

average rate of change = (50(0.9)^5 - 50(0.9)^8) / (5 - 8)

average rate of change = 8.0011 / -3

average rate of change = -2.667

22.

Initial value: 25

Decay factor: 0.8

2 ≤ x ≤ 4 and

6 ≤ x ≤ 8

f(x) = 25(0.8)^x

average rate of change for x = 2 and x = 4

average rate of change = (25(0.8)^2 - 25(0.8)^4) / (2 - 4)

average rate of change = 5.76 / -2

average rate of change = -2.88

average rate of change for x = 6 and x = 8

average rate of change = (25(0.8)^6 - 25(0.8)^8) / (6 - 8)

average rate of change = 2.3593 / -2

average rate of change = -1.1797

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Answer:

Eight 6-packs

Step-by-step explanation:

6-pack of hot dogs for 5.10$

8-pack of hot dogs for 6.88$

To figure out the answer, we compare the prices:

The price of six 8-packs is $41.28 ($6.88 x 6)

The price of eight 6-packs is $40.80 ($5.10 x 8)

As we can see, the cheaper option would be to buy eight 6-packs, which is our answer.

System:

5b+2m=5.5
6b+10m=12.3

Variables:

b = cost of bananas
m = cost of mangoes

Explanation:

Zachary bought 5 bananas and 2 mangoes so you multiply each by the cost of them (5b and 2m) and then add them together (5b+2m) to find the total cost (5.5). This is the same for Olivia. If you solve the system you can figure out how much the bananas and mangoes cost.

The cost of the bananas and the mangoes will be $0.80 and $0.75, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Zachary went into a supermarket and purchased 5 bananas and 2 mangos, costing a sum of $5.50. Olivia went into a similar supermarket and purchased 6 bananas and 10 mangos, costing a sum of $12.30.

Let 'x' be the cost of a banana and 'y' be the cost of a mango. Then the equation is given as,

5x + 2y = 5.50               ...1

6x + 10y = 12.30            ...2

From equations 1 and 2, then we have

6x + 10[(5.50 - 5x) / 2] = 12.30

6x + 27.5 - 25x = 12.30

19x = 15.2

x = $0.8

Then the value of the variable 'y' is given as,

5(0.8) + 2y = 5.50

4 + 2y = 5.5

2y = 1.5

y = $0.75

The cost of the bananas and the mangoes will be $0.80 and $0.75, respectively.

a ((13 - 6 a) a - 3) - 2

Step-by-step explanation: hope this helps.

Slope-intercept form is: y = mx + b

where m is the slope and b is the y-intercept.

Since you're told the slope is 1/8 and the y-intercept is -7, you just plug those into the form:

    y = 1/8 x - 7

Note that the "–" in front of the 7 is already part of the answer on paper, so you don't need to add a second one.
