Answer:

This is a vertical line; there is no change in the x coordinate value; and since the slope is defined to be change in y any attempt to corresponding change in x evaluate the slope would result in an attempt ot divide by zero.

Step-by-step explanation: plz tell me lol

Answer:

a3=15 , n=3

a8=0, n=8

a5 = ?

an = a1+ (n-1)d

a3 = a1 + (3-1) d

a3=a1+2d

and a8 = a1 + (8-1 )d

a8= a1+ 7d

15 = a1 + 2 d-------1

0= a1 +7 d----------2

substacting eq 2 from eq 1

15= - 5d

- 5d = 15

divide by - 5

d = -3

putting the value of d in eq 1

15 = a1 + 7 (-3)

15 = a1 -21

adding 21 on both sides

a1-21+21= 15+21

a1 = 36

a5 = ?, n=5, d= -3, a1=36

a5 = 36 + (5-1) (-3)

= 36+(4)(-3)

= 36-12

= 24

Answer:

this angle is a right angle(90°)

and one of the 2 angles is 30

3x+30=90

3x=90-30

3x=60

x=20

==> B

Answer:

B. Add two -1 counters to each side

Step-by-step explanation:

If you were to do this problem normally you would subtract 2 from each side so B just makes sense.

Answer:

negative trend because the values are decreasing

Answer:

f(1) = 1

Step-by-step explanation:

To go 1 on the x-axis and check to see where it is on the y-axis. In this case, when x = 1, y = 1.

Therefore, f(1) = 1.

64  because its real :)

Answer:

A

Step-by-step explanation:

Multiply:

[tex](\frac{5}{5+\sqrt{10x} } )(\frac{5+\sqrt{10x} }{5+\sqrt{10x} } )[/tex]

Simplify:

[tex]\frac{5(5-\sqrt{10x}) }{(5+\sqrt{10x})(5-\sqrt{10x} ) }[/tex]

Factor:

[tex]\frac{5(5-\sqrt{10x}) }{25-10x}[/tex]

Reduce:

[tex]\frac{5(5-\sqrt{10x}) }{5(5-2x)}[/tex]

Solution:

[tex]\frac{5-\sqrt{10x} }{5-2x}[/tex]

Answer:

  30°

Step-by-step explanation:

The angle a line makes with the x-axis is arctan(slope). Here, that is ...

  angle with x-axis = arctan(√3) = 60°

So, the angle made with the y-axis is the complement of this:

  angle with y-axis = 90° -60° = 30°

The third option with the decimal on top as a fraction

Answer:

C

Step-by-step explanation:

Think of the proportional relationship as algebra.

k*number of MovieTickets = Cost, where k is the constant of proportionality.

To find k, you can substitute values in the table and solve for k.

In this example:

k*5 = $28.75

k = $28.75/5

This answer is C.

Step-by-step explanation:

30% of lightbulbs = 45 lightbulbs

100% of lightbulbs

= 45 * (100/30) = 150 lightbulbs.

Hence there are 150 lightbulbs in the batch.

Answer:

For a function f(x) = y.

The independent variable is the one that we chose to input in the function, in this case, is x, and the dependent variable is the variable that changes in response to the independent variable, in this case, is y.

In this problem we have:

"Sammy has $180 in her savings account and plans to deposit $20 each month."

We can define:

y = money in her savings account

x = number of months that have been passed since she started saving.

Originally, she has $180, and she saves $20 per month, so if x months have been passed, the total amount of money in her savings account is:

y = f(x) = $180 + $20*x

Now we want to know if this function is continuous or discrete, to see this we need to look at the possible values of x.

x represents the number of months that have been passed, then the values that x can take are:

x = 0, 1, 2, 3, 4, ...

So x can only take the values of positive integers, this means that the domain of x is discrete, then the function f(x) is a discrete function.

Answer:

1 7/12

Step-by-step explanation:

Answer:

C) It is one-half the area of a rectangle of length 4 units and width 5 units.

The total area of the triangle is 10, which we get by multiplying the height (5) times the base (4), which will be 20, and then dividing by 2, which is 10!

Given this information, we can start eliminating answers.

A) It is twice the area of a rectangle of length 4 units and width 5 units. This is answer is wrong, as the area of a rectangle with a length of 4, and a width of 5, is 20. Meaning that in order for this to be true, the area of the rectangle must be 40, which it is not.

B) It is one-half the area of a rectangle of length 4 units and width 5 units.

This is answer is right, as the area of a rectangle with a length of 4, and a width of 5, is 20, and half of that would be 10, which is half of the area of the triangle!

C) It is twice the area of a square of side length 5 units.

This answer is also wrong because the area of a square with side lengths of 5 would be 25, which is not half of the area of the triangle. In order for this to be true, the area of the rectangle must be 50, which it is not.

D) It is one-half the area of a square of side length 5 units.

This answer is wrong because the area of a square with side lengths of 5, would be 25, which is not twice the the area of the triangle. In order for this to be true, the area of the rectangle must be 12.5, which it is not.

Answer:

I feel like it might or might not be rectangle because it didn't pass through the vertex so it's almost like it's cutting off the top part of the pyramid.

Answer: Trapezoid

Step-by-step explanation:

I just did the test and got 100

Answer:

1 ½% of x = 15

3/2 × x = 15

x = 15/1.5

x = 10

So

1½ 15

— = —

100 10
