Rei is barricading a door to stop a horde of zombies. She stacks boxes of books on a table in front of the door. Each box weighs 30 kilograms, and the table with 8 boxes on top weighs a total of 310 kilograms.
The total weight W of the barricade in kilograms is a function of x, the number of boxes Rei stacks on the table.
Write the function's formula.
W, equals

Answer:

The answer is C

Step-by-step explanation:

5(-8) is equal to -40 and -40 minus 2 would give you -42

You could try it with the others if you want

Answer:

The answer is C

Step-by-step explanation:

to find slope do

-42 - (-17) = -25

and

-8 - (-3) = -5

then

-25/-5 = 5 as the slope

to find the y-intersept look where x = 0

so the y-intersept is -2

linear equation is y=mx+b

m = slope

b = y-intersept

so y = 5x - 2

Answer:

No

Step-by-step explanation:

The angles of the two triangles don't match, and the two sides given aren't congruent, so it is impossible for the triangles to be congruent.

Answer:

50

Step-by-step explanation:

32 - 6 = 26

26 + 18 = 44

44 - 3 = 41

41 + 18 = 59

59 - 9 = 50

Answer: 55 people attend aerobics at Martha’s altogether

Step-by-step explanation:

Martha conducts aerobics three times a week in her home.

Number of members in first group = 19 members

Number of members in second group = 22 members ; and

Number of members in third group = 14 members

To find the number of people who attended aerobics we have to add the number of members in all tge three groups.

So, number of people who attended aerobics at Martha’s altogether = 19 + 22 + 14 = 55 members

Hope it helps.

Answer: See explanation

Step-by-step explanation:

7x - 2(x + 3y) + 3y

= 7x - 2x - 6y + 3y

= 5x - 3y

Will got 5x + 9y because he didn't multiply the values in the bracket by the minus sign outside the bracket. He multiplied the values by +2 rather than -2. This resulted in the wrong answer that he got.

Answer:

0 pints ≤ J ≤ 4 pints

Where J is the amount of juice that Carl bought.

Step-by-step explanation:

Here we need to learn how to use the inequality symbols.

Let's define each one of them:

A < B   (A is strictly smaller than B)

A > B  (A is strictly greater than B)

A ≤ B (A is smaller than or equal to B)

A ≥ B  (A is greater than or equal to B)

A ≠ B  (A is different than B)

Ok, in this case, we know that Carl buys 4 one-pint cartons of milk.

Then the total amount of mil that he buys is 4 times one pint, this is:

4*1 pint = 4 pints

He has 4 pints of milk.

And we know that he buys less juice than milk, then if J represents the amount of juice that he bought, we need to have:

J < 4 pints

This means that the amount of juice that he bought is smaller than the quantity of milk that he bought (4 pints)

If we want to be more correct, we should write:

0 pints ≤ J ≤ 4 pints

Here we say that J needs to be a positive number (we can't buy a negative quantity of juice)

Answer:

$2.50+$1.25 times M

Step-by-step explanation:

$10.75-$8.25=$2.50

$3.50-$2.25=$1.25

$2.50+$1.25=$3.75

As only one-time fee, we cancel out it, then only add on the per-month fee, which is $1.25 every month.

Answer:

d

Step-by-step explanation:

y=2x+23

2x is the for the number of people added every month and 23 is for the number you start with

The equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

In slope-intercept form, an equation of a line is represented as y = mx + b, where m is the slope (or rate of change) and b is the y-intercept (or the point at which the line crosses the y-axis).

Let's represent x is the number of months and y is the number of members.

The number of members y in x months is a linear function of the number of months, with a slope of 2 (the number of members added per month) and a y-intercept of 23 (the number of members at the beginning).

Thus, the equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23

Answer:

377 cm2 !!!!! i hope its correeect!> <

Step-by-step explanation:

Answer:

22 4/5 miles

Step-by-step explanation:

miles per gallon = total miles / total gallons used

[tex]15\frac{1}{5}[/tex] ÷[tex]\frac{2}{3}[/tex]

convert the mixed fraction to an improper fraction

[tex]\frac{76}{5}[/tex] × [tex]\frac{3}{2}[/tex] = [tex]\frac{114}{5}[/tex] = 22 4/5 miles

Raise 5 to the 3rd power:

(5y)^3 = 5^3y^3 = 125y^3

The answer is 125y^3

Answer:

3

Step-by-step explanation:

Finding a GPA is just like finding an average, you add up all of the different outcomes and divide it by the total amount of outcomes and you will get the average. You also need to know how many points each letter grade is worth. It is normally A=4.0 B=3.0 C=2.0 D=1.0 and F=0. In this case here is what you will add,

3+4+3+2=12

Now that you have the total number of points you need to divide the total by the total outcomes which would be,

12/4=3

The correct matches are 1-G, 2-B, 3-C, 4-A, 5-F, 6-D, and 7-E.

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]

where a is a constant and a>1

1. A function in the form of y = aˣ is the exponential function.

2. "x" in the exponential form y = aˣ is the exponent.

3. A logarithm with a natural base of e is called a natural logarithm.

4. The rectangular arrangement used to organize data is a matrix.

5. "a" in the exponential form y = aˣ is the base number.

6. A logarithm with a natural base of 10 is called a common logarithm.

7. The equivalent form of an exponential function is called logarithm.

Thus, the correct matches are 1-G, 2-B, 3-C, 4-A, 5-F, 6-D, and 7-E.

#SPJ5

Answer:

Third option : 9^10 / 9^2

Step-by-step explanation:

9^2 . 9^6

Formula / Identity : -

a^m . a^n = a^( m + n )

Here,

a = 9

m = 2

n = 6

9^2 . 9^6

= 9^( 2 + 6 )

=9^8

9^10 / 9^2

Formula / Identity : -

a^m / a^n = a^( m - n )

Here,

a = 9

m = 10

n = 2

9^10 / 9^2

= 9^( 10 - 2 )

= 9^8

Therefore,

9^10 / 9^2 is equivalent to 9^2 . 9^6.
