Use the following sets to answer the question.
A={1,2,3,4,5}
B={5,6,7,8,9}
Which answer shows the intersection of A and B?

{1,2,3,4,5,6,7,8,9}
{1,2,3,4,6,7,8,9}
{2,4,8}
{5}

Given:

The function is

[tex]f(x)=-3x^2+2x-7[/tex]

To find:

The value of f(-1).

Solution:

We have,

[tex]f(x)=-3x^2+2x-7[/tex]

Putting x=-1, we get

[tex]f(-1)=-3(-1)^2+2(-1)-7[/tex]

[tex]f(-1)=-3(1)-2-7[/tex]

[tex]f(-1)=-3-9[/tex]

[tex]f(-1)=-12[/tex]

Therefore, the value of f(-1) is -12.

Answer:

13/30

Step-by-step explanation:

There are seventeen red and thirteen green apples in a bag. I am going to take out an apple without looking. What is the probability that the apple will be green?

The Probability that the apple that will be picked is green is calculated as:

Number of green apples/ Total number of apples

Total number of apples = 17 red apples + 13 green apples

= 30 apples

Hence:

P( Green apples) = 13/30

Answer:

10

Step-by-step explanation:

Turn this into multiplication by doing 12*(5/6) = 10

The graph formed by equation y= -2/3x+10 will be perpendicular to the graph by equation y=3/2x-10.

A line in the form of ax + by + d = 0 will be a linear equation and if we convert it into the form of y = mx + c where m will be the slope of that equation.

If two lines are perpendicular to each other then the product of their slope of them will be (-1).

⇒  m₁ ₓ m₂ = -1

The slope of line 2x + 3y = 10 will be -2/3

To be any line perpendicular whose slope m with the 2x + 3y = 10

⇒ -2/3 × m = -1

⇒   m = 3/2 so the slope of that line should be 3/2

Hence, line y=3/2x-10 will be perpendicular to the 2x + 3y = 10.

Answer:

156 square feet

Step-by-step explanation:

The area of Brian's rectangular garden, in square feet, can be found by using the expression 6(2x + 5y).

If x = 3 and y = 4

Substituting

6(2 × 3 + 5 ×4) square feet

6(6 + 20) square feet

Using Distributive property

6(6 + 20) square feet =( 6 × 6) + (6 × 20) square feet

6(6 + 20) square feet =(36+ 120) square feet

6(6 + 20) square feet = 156 square feet

Therefore, the area of Brian's rectangular garden, in square feet is 156 square feet

Answer:

KA = 28

∠KBL = 90°

Step-by-step explanation:

KA = KB (both are radii)

KB = 28, so KA = 28

∠KBL = 90° because tangents are perpendicular to the radius

Answer:

Hank

8x+12x=180

Step-by-step explanation:

Hank is correct because the angles that are given are supplementary so they are going to add up to 180. Jill is incorrect because the angles are not congruent

This is the correct answer once again because the angles are supplementary so the two added with equal 180

Answer: y = 2/1x + 2

Step-by-step explanation:

A slope of 2 means rising 2 and run 1 on a graph. This would make x = 2/1. The + 2 allows the line to pass through (0,2) and therefore it will also pass through (-2,-2).

Answer:

A

Step-by-step explanation:

multiply 0 by 2 | 0 x 2 = 0

subtract 5 from 0 | 0 - 5 = -5

multiply 2 by 2 | 2 x 2 = 4

subtract 5 from 4 | 4 - 5 = -1

The table that represents the same linear relationship as the linear equation y = 2x - 5 is; Table A

The given equation is; y = 2x - 5

For the first table;

At x = 2, we have;

y = 2(2) - 5

y = -1

This and other values with input of x corresponds with the table.

For the second table;

At x = 2, we see that y = 1 instead of -1 and so this table is not correct.

For tables 3 and 4, we see that when we see that they both give the wrong values of y at x = 0 and so they are both wrong.

Answer:

range = 6

IQR = 3.5

Step-by-step explanation:

range is greatest - least

18-12=6

IQR is the difference between quartile 3 and quartile 1

to find IQR you would want to put the numbers in order first

12, 12, 13, 13, 14, 15, 17, 18

then find the median of that set of numbers (you don't need to find the exact number just know where it is)

12, 12, 13, 13, || 14, 15, 17, 18

so the median is between 13 and 14 (where the || is)

then we find the median on both sides of the ||

find the median of 12, 12, 13, 13 and 14, 15, 17, 18

12, 12, || 13, 13  and  14, 15, || 17, 18

the medians are 12.5 and 16

subtract 12.5 from 16 to get 3.5

the IQR is 3.5
