Answer:

1) Slope= 2, y-intercept=4, equation: y=2x+4

2.Slope= -10 , y-intercept= 60 , equation: y=-10x+60

Step-by-step explanation:

Slope formula: [tex]\frac{y_{2}-y_1 }{x_2-x_1}[/tex]

1. Plug in two sets of cordinates into the equation

(0,2) (2,8)

2. Solve, slope =2

3. Plug in one pair into the point slope formula

Point slope formula: [tex]y-y_1=slope(x-x_1)[/tex]

4. y-8=2(x-2)

5.y-8=2x-4

6. y=2x+4

Do the same for the other equation

Answer 2

Answer:

1: slope

2: y-intercept

1a: slope= 3

If EF = 6 and EG = 23, find the value of FG.

Answers

Answer:

FG=138

Step-by-step explanation:

Since 23 is a prime number, the only factors of it are 1 and 23.

Which means E is either 1 or 23.

Since 23 is not a factor of 6, E=1. Therefore, G= 23. And, F=6.

So, FG=23*6, which means FG=138.

Answer: 17

======================================================

Explanation:

This is a piecewise function. It's composed of 3 pieces of other functions. A piecewise function is a function that changes its identity based on what the input is.

We have three different situations here

If t = 17, then h(t) = sqrt(17t) based on what the first row saysIf t = 19, then h(t) = -34/t which is the second row of the piecewise function.If t does not equal either 17 or 19 (ie t is anything but those values), then h(t) = 23-t

The notation h(17) means we want to evaluate h(t) when t = 17. So we'll use the first case mentioned above. Plug t = 17 into h(t) = sqrt(17t) to get...

h(t) = sqrt(17t)

h(17) = sqrt(17*17)

h(17) = sqrt(17^2)

h(17) = 17

In the last step, I used the rule that sqrt(x^2) = x when x is nonnegative.

What is the domain of the function graphed below?

Answers

Answer:

Domain: 0, 5

Range: 0, 2

Step-by-step explanation:

The Domain is the first coordinate which is x.

The Range is the second coordinate which is y.

Hope This Helps :)

The domain of the function will be 0 < x ≤ 5. The correct option is A.

What is a domain?

In mathematics, a domain typically refers to a set of values for which a particular function or equation is defined. For example, the domain of the function f(x) = 1/x is all real numbers except for x = 0 since the function is undefined at that point.

The Domain is the first coordinate which is x. The Range is the second coordinate which is y.

The domain of the given graph in the image will be calculated as,

0 < x ≤ 5

Therefore, the correct option is A.

for the past five baseball seasons miguel had 122 45 109 124 and 115 hits what is his median number of hits for the past five seasons

Answers

Answer:

His median hit = 115

Step-by-step explanation:

Given:

122 45 109 124 and 115 hits

To find his median hit, you will either arrange the hits in ascending order or descending order

In ascending order (lowest to highest value)

45, 109, 115, 122, 124

In descending order (highest to lowest value)

124, 122, 115, 109, 45

It can be observed that thehe hits are 5

The median is the middle value

From either the ascending or descending order arrangement, 115 is the middle hit.

Therefore, his median hit = 115

2 factory plants are making TV panels. Yesterday, Plant A produced 6000 fewer panels than Plant B did. Two percent of the panels from Plant A and 5% of the panels from Plant B we’re defective. How many panels did Plant B produce, if the two plants together produced 1140 defective panels

Answers

Answer:

Number panels Plant B produce = 18,000

Step-by-step explanation:

Given:

Plant produces defective panels = 1140

Plant B produce = 5%

Plant A produce = 2%

Find:

Number panels Plant B produce

Computation:

Assume

Number panels Plant B produce = x

Number panels Plant A produce = x - 6000

5%(x) + 2%(x-6000) = 1140

0.05x + 0.02x - 120 = 1140

0.07x = 1260

x = 18,000

Number panels Plant B produce = 18,000

what value of n makes the equation ? 4(0.5-3)=n-0.25(12-8n)

Answers

Answer:

4(0.5-3)=n-0.25(12-8n)

2-12=n-3+2n

-10=-3+3n

-10+3=3n

-7=3n

n=-2.3

Answer: n= -7/3

Step-by-step explanation:

4(0.5 - 3) = n - 0.25(12 -8n) solve for n .

2 - 12 = n - 3 + 2n

-10 = 3n - 3

+ 3 +3

n = -7/3

Alessandra is raising turtles and must keep the air temperature in their enclosure at 32. C , with a relative error less than 3%. Write an absolute value inequality for the actual temperature

Answers

The absolute value inequality for the temperature T is:

|T - 32°C| < 0.96°C

How to write the absolute value inequality?

The general way of writing these inequalities is:

|variable - average value| < accepted error.

Here the variable is the temperature so we can use T for it.

The average is 32°C, and the accepted error is less than 3%, so it is:

0.03*32°C = 0.96°

Then the absolute value inequality will be:

|T - 32°C| < 0.96°C

Where it means that the temperature will be at less of 0.96°C of the 32°C.

Two expressions that denoted the legal fees for x hours:

350x + 22,000 ____(1)

410x+16,000 _____(2)

Where x = number of hours

The number of hours where both the legal fees are equal:

350x + 22,000 = 410x + 16,000

Subtract 350x on both sides.

22,000 = 410x -350x+ 16,000

22,000 = 60x + 16,000

Subtract 16,000 on both sides.

22,000 - 16,000 = 60x

6,000 = 60x

Divide both sides by 60.

x = 100

Thus,

The number of hours of legal assistance that makes the expressions 350x+22,000 = 410x+16,000 true is 100 hours.
