Answer:

The steps to do this :

[tex]2(g - h) = b + 4[/tex]

[tex]g - h = \frac{b + 4}{2} [/tex]

[tex]g = \frac{b + 4}{2} + h[/tex]

[tex]g = \frac{b}{2} + \frac{4}{2} + h[/tex]

[tex]g = \frac{b}{2} + 2 + h[/tex]

2(g - h)=b + 4

Use the distributive property on the left side:

2g - 2h = b +4

Add 2h to both sides:

2g = 2h + b + 4

Divide both sides by 2:

g = (2h + b + 4)/2

Simplify:

g =  b/2 + 2 + h ( note the order of h, 2 and b/2 can be different)

Answer:F(x) = 10x+30

Step-by-step explanation:

X=3

The function which represents the test score determined by the number of correct answers is f(x) = 30 + 10x.

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.

According to the given question

We have

Total number of problems in a math test = 7

Total points given to each problem if it is correct = 10

Every text taker receives  points for taking a test = 30

Let x represents number of correct answers given by the test taker and f(x) be the total score earned by the test taker.

Now, the function or linear equation  in two variable which represent the given scenario is

f(x) = 30 + 10x

Hence, the function which represents the test score determined by the number of correct answers is f(x) = 30 + 10x.

Step-by-step explanation:

Answer:

$2

Step-by-step explanation:

Credits:

Jason initial amount in his account = $6

Amount deposited for the week = $7

Total credit = $7+$6

Total credit = $13

Debit:

Cost of lunch bought on Tuesday = $2

Cost of lunch bought on Thursday = $5

Cost of lunch bought on Friday = $4

Total cost of lunch for the week = $2+$5+$4 = $11

Amount debited = $11

Balance left after he bought lunch on Friday = amount credited - amount debited

Balance = $13-$11

Balance = $2

Hence Jason had $2 balance left after buying his Friday lunch.

The answer is C:41

Step-by-step explanation:

you have to set 6x-7 equal to 5x-1 which equals x=8 which now you replace x in 6x-7 with 8 which makes the equation 6(8)-7 which equals 41.

Answer:

Since M is the midpoint that means that LM is equal to MN so therefore

6x-7=5x+1

-5x from both sides

x-7=1

add 7 to both sides

x=8

then you substutie 8 for x in 6x-7

The value of pi is about 3.14, and it is the same when using both the area and circumference.

The circumference is given by:

Circumference = π * diameter

For circle A:

25.12 = π * 8

π = 3.14

For circle B:

9.42 = π * 3

π = 3.14

The area is :

Area = π * diameter² / 4

For circle A:

50.24 = π * (8²)/4

π = 3.14

For circle B:

7.065 = π * (3²)/4

π = 3.14

Answer:

y = 10x - 6

Step-by-step explanation:

If we know the function is linear then we can use any two coordinate pairs to find the slope of the line.

Note that the first pair is (0, -6) and the last pair is (4, 34).  The 'run' is from x = 0 to x = 4, a 'run' of 4.  The 'rise' is from -6 to34, a 'rise' of 40.  Thus, the slope of this line is m = rise / run = 40/4 = 10.

Again using the coordinate pair (0, -6), along with the slope-intercept form of the equation of a straight line, we get:

-6 = 10(0) + b, so we know that b = - 6 and that the equation of this line must therefore be:

y = 10x - 6

The required slope-intercept form of the function is y = 10x - 6.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
m = (y₂ - y₁) /  (x₂ - x₁)
Substitute 2 pairs from the table in the above equation,
m = (4 + 6)/(1-0)
m = 10
Now put the slope and one pair in the slope-intercept form of the equation

y - y₁ = m (x - x₁)
y + 6 = 10(x - 0)
y = 10x - 6

Thus, the required slope-intercept form of the function is y = 10x - 6

A. greater than 0.3

The Margin of error is 0.3 when assuming a 90% confidence level.

It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.

The formula for finding the MOE:

MOE = z score * s/√n

Where   is the z score at the confidence interval

            s is the standard deviation

            n is the number of samples.

here, we have,

It is given that among 320 randomly selected airline travelers, the mean number of hours spent traveling per year is 24 hours and the standard deviation is 2.9.

It is required to find the margin of error when the confidence level is 90%.

We have in the question:

at 90% confidence interval = 1.645 (From the Z score table)

s = 2.9

n = 320

Put the above values in the formula, we get:

MOE = 0.2666

Rounding the nearest tenth:

MOE = 0.3

Thus, The Margin of error is 0.3 when assuming a 90% confidence level.

The bar that represents the bar that would be the largest in a histogram would be 2/15.

To identify the bar that would be the largest in a histogram we must take each of the options and perform the division to obtain a decimal number. Once we have all the decimal numbers, we must identify which is the largest of them and thus we will know which one would represent a larger bar in a histogram. Here is the procedure:
