Answer:

7a) 6X + 24

7b) 4X + 17

8) $142

Step-by-step explanation:

7a) you first combine the variables / letters. Then the numbers

1. 4x + 2x = 6x

2. 29 - 5 = 24

6x + 24

7b) you first combine the variables / letters. Then the numbers

1. x + 3x = 4x

2. 10 + 14 - 7 = 17

4x + 17

8) I did 12a + 8b + 6b

1. plug in your numbers into the variables / letters  12( 6 ) + 8 ( 5 ) + 6 ( 5 ) = ?

2. Then do the individual numbers 72 + 40 + 30 = ?

3. Then you can combine them all 142

Answer:

6in²

Step-by-step explanation:

the problem says the two triangular prisms are congruent.

the first triangle's volume is 90in³ and the height of the second triangular prism is 15. we use the formula fro the volume of the shape:

V=B * h

we substitute the values we know:

90in³=B*15

90/15 = B

6in²= B

So the area of the base is 6in²

Hope this helps :)

Answer:

C

Step-by-step explanation:

We want a line of best fit, which means we want to create a line that the data points will lie closest to.

One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.

Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:

(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4

Eliminate A and B.

Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.

The answer is C.

Answer:

C

Step-by-step explanation:

The slope of the line of best fit should be around:

(18-15)/(16-10) = 0.5

And

The y-intercept would be less than 15

Therefore, option C is the most suitable option

Answer:

Perimeter = sum of length of all sides = 8 + 3 + 10 + 11 = 32

Area = (base1 + base2) x height/2 = (3 + 11) x 7/2 = 49

Answer:

Divide each side of 18/4 by 2 to get 9/2.

Answer:

184/10

Step-by-step explanation:

You have to delete the comma (,) so, by doing ×10 you have 18,4 -> 184. By doing ÷10 you have a fraction: 184/10 that is equal to 18.4

Answer:

The inverse of the function y = 5x - 10 would be:

5x - 10 = y

or

5x = y + 10

or

x = (1/5)y + 2

Hope this helps!

:)

The inverse of the function y=5x-10 is given by the formula f^-1(x) = (x + 10)/5. This is found by switching x and f(x) in the original equation, then solving for the new function.

The problem asked us to find the inverse of the function y=5x-10. Finding the inverse of a function involves reversing the variables and then solving for the new y variable. Here are the steps for this:

The multiplicative rate of change of the function is (b) 3/4

The table entries are given as:

x  y

1 3/2

2 9/8

3 27/32

4 81/128

From the above table, we have:

y1 = 3/2

y2 = 9/8

Divide y2 by y1 to get the multiplicative rate of change (r)

[tex]r = 9/8 \div 3/2[/tex]

Evaluate the quotient

r = 3/4

Hence, the multiplicative rate of change of the function is (b) 3/4

Given Function A with points (–5, –2), (–5, 7) and Function B with points (7, –5), (–2, –5) represent linear functions, thus:

Function A has an undefined slope: no slope

Equation for line A would be: x = -5

Function B has a slope value of: 0.

Equation for line B is: y = -5

Recall:

Thus:

Linear Function A with the points (–5, –2), (–5, 7):

[tex]Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 -(-2)}{-5 -(-5)} \\\\[/tex]

[tex]m = \frac{9}{0}[/tex] (can't divide. Undefined)

The equation for function A will therefore be written as: x = -5

Linear Function B with the points (7, –5), (–2, –5):

[tex]Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-5)}{-2 - 7} \\\\[/tex]

[tex]m = \frac{0}{-9} = 0[/tex]

The equation for function A will be written as: y = -5

In summary, given Function A with points (–5, –2), (–5, 7) and Function B with points (7, –5), (–2, –5) represent linear functions, thus:

Function A has an undefined slope: no slope

Equation for line A would be: x = -5

Function B has a slope value of: 0.

Equation for line B is: y = -5

Final answer:

To find out how many one-inch cubes are on a single edge of the larger cube formed by stacking 216 cubes, take the cube root of 216, which is 6. Therefore, each edge has 6 one-inch cubes.

Explanation:

If there are 216 one-inch cubes stacked to form a larger cube, we need to determine how many cubes are along each edge of this larger cube. The volume of a cube is calculated as length × width × height, and since all sides of a cube are equal, we can say that the length, width, and height are all the same. Therefore, to find the length of one side, we take the cube root of the volume. The cube root of 216 is 6, meaning each edge of the larger cube is composed of 6 one-inch cubes.

Answer:A

Step-by-step explanation:

The required profit function is defined for all s and t greater than or equal to zero. Option A is correct.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,

The profit function P=6t+10s represents the profit made by a company based on the number of units of two products: t units of product 1 and s units of product 2.

In general, the domain of the profit function depends on the specific context of the problem, but in the problem, we have no constraints so the domain of the profit function would be all real values for s and t greater than or equal to zero.  

Thus, the required profit function is defined for all s and t greater than or equal to zero. Option A is correct.

The correct answer is:

The possible value for the 6th term is 40. Thus, the answer is B) 70.

To find the common ratio (r) of the geometric sequence, divide the 7th term by the 5th term:

[tex]\[ r = \frac{40}{160} = \frac{1}{4} \][/tex]

Now, we can find the 6th term (T6) using the common ratio and the 5th term:

[tex]\[ T6 = T5 \times r = 160 \times \frac{1}{4} = 40 \][/tex]

So, the 6th term could be 40. Therefore, the answer is:
