Answer:

the slope is: Positive

slope is: 1/5

y-intercept: -4

equation is: y = 1/5x - 4

Answer:

Slope: Postive

Slope: 5

Y-Intercept: -4

Equation: y = 5x - 4

Step-by-step explanation:

A positive slope rises left to right, a negative slope rises right to left.

The slope is [tex]\frac{rise}{run}[/tex].

The y-intercept is where the line meets the y-axis.

The equation is written in the form y = mx + b, where m is the slope and b is the y-intercept.

Hope it helps and is correct!

Given

[tex]7x - 2 = 26[/tex]

Step 1

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.

Answer: 3

Step-by-step explanation:

The larger triangle is 5 times the size of the smaller triangle. Notice 6 increased to 30. How? 5x6 = 30, so it increased in size 5 times. The rise of the larger triangle is 15. If we know that 15 is 5 times as large as the smaller rise, then 15 divided by 5 = 3. So the smaller rise is 3

Answer:

Missing rise is 3

Step-by-step explanation:

[tex]\frac{30}{15} =\frac{6}{x}\\[/tex]

30x=90

x=3

1 x 20

2 x 10

4 x 5    (these go the other way round as well, like 10 x 2, etc)

all factors of 20 = 1,2,4,5,10,20

Answer:

£ 6,564.70

Step-by-step explanation:

Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years

Compound Interest formula =

A = P(1 + r/n)^nt

A = Final Amounrt

P = Principal = £6,000

r = Interest rate = 4.6%

t = Time in years = 2 years

n = Compounding frequency = Yearly = 1

First, convert R percent to r a decimal

r = R/100

r = 4.6%/100

r = 0.046 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 6,000.00(1 + 0.046/1)^(1×2)

A = £ 6,564.70

The amount in his account after 2 years = £ 6,564.70

Answer:

850.9 feet

Step-by-step explanation:

The horizontal distance between Ryan and the dolphin is 850.907 feet.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.

Using trigonometry

tan 15 = 228/ x

x= 228/ tan 15

x= 228 / 0.26794919243

x = 850.907  feet

Answer:

Step-by-step explanation:

-40x + 8y = -24

 3x  -  8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24     (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3

Options B,D, and E are correct as per the given Function of the revenue.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

A. At $2 per coffee mug, the revenue will be $196.

This statement is incorrect.

If the price per mug is $2, then the revenue would be (220 - 12x) * 2. If x = 12 (i.e. 12 mugs are sold), then the revenue would be (220 - 12(12)) * 2 = $176.

B. The school expects to sell 160 mugs if the price is $5 each.

This statement is correct.

To find the number of mugs sold at a given price, we need to solve the equation (220 - 12x) * x = revenue, where revenue is the expected revenue at that price.

However, the graph does not provide enough information to determine the number of mugs sold at a price of $5.

C. The school will lose money if it sells the mugs for more than $10 each.

This statement is incorrect. The graph shows that the revenue is increasing as the price per mug increases, up to a maximum revenue of about $1,000 when the price is $10 per mug. Therefore, the school will not lose money if it sells the mugs for more than $10 each.

D. The school will earn about $1,000 if it sells the mugs for $10 each.

This statement is correct. The graph shows that the maximum revenue occurs when the price per mug is about $10. At this price, the revenue is approximately $1,000.

E. The revenue will be more than $700 if the price is between $4 and $14.

This statement is correct.

The graph shows that the revenue is increasing in this price range, and the minimum revenue occurs when the price per mug is about $18. Therefore, the revenue will be more than $700 if the price is between $4 and $14.

F. The expected revenue will increase if the price per mug is greater than $10.

This statement is incorrect. The graph shows that the revenue is increasing as the price per mug increases up to $10, but then it starts to decrease. Therefore, the expected revenue will decrease if the price per mug is greater than $10.

Answer:

Yes, that is true.

Step-by-step explanation:

The bounded regions of the two inequalities do not overlap, so there is no solution set. However, the existence of parallel lines does not necessarily indicate that there is no solution, it just means that there is the possibility of no solutions.
