What is the equation of the line containing the points (-1,9) and (2,18)

Answer:

y=-2

x=4

Step-by-step explanation:

4x+y=14

x-2y=8 then x=8+2y

substitute for x in 4x+y=14

4(8+2y)+y=14

32+8y+y=14

reduce

32+9y=14

32+9y-32=14=32

9y=-18

9y/9=-18/9

y=-2

x=8+2(-2)=4

Answer: The odds of drawing a King or a heart are P(E)/P(E') = (4/13)/(9/13) = 4/9. What is the probability of getting at least one black card in a 7-card hand off a shuffled 52-card deck

Step-by-step explanation:

Answer:

Step-by-step explanation:

It would be 11 x 13, because 11 x 13 = 143.

Check: 11 and 13 are both consecutive odd numbers.

Check: 11 x 13 = 143.

Answer:

11 x 13

Step-by-step explanation:

You just sort of have to tinker around! That will help you gauge the range of the answer and eventually find it!

Hope that helps!

Answer:

neither; neither; supplementary

Step-by-step explanation:

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.

First picture: 32° + 48° = 80°

80° < 90° and 80° < 180°

Therefore they are neither

Second picture: 101° + 77°  = 178°

178° > 90° and 178° < 180°

Therefore they are neither

Third picture: 107° + 73° = 180°

180° < 90° but 180° = 180°

Therefore they are supplementary

neither neither and supplementery cus i smrt

Answer:

D-$4,900

Step-by-step explanation:

Answer:

The answer is D. $4,900

Step-by-step explanation:

$196 in commissions  => a = 196

s = a / 0.04 = 196 / 0.04 = $4900 = Ann's sales

so the answer for Ann's sales is $4,900

Answer:

the answer is 9.4

Step-by-step explanation:

9 4/10= 9+1/10

we know that 4/10 is the same as 4÷10.

therefor:

9 4/10=9+(4÷10)

then using long division for 4 divided by 10 we have:

=9+0.4=9.4

Answer:

Answer:

5 - x=90°

6- angle c= 75°

7- angle a = 90°

Answer:

c = 75

Step-by-step explanation:

All triangles add up to 180. Add the two angles which you have, and then subtract that from 180. that will be your third angle value.

Answer:

4 equation 4

Step-by-step explanation:

did math in head

Answer:

Equation 4.

Step-by-step explanation:

2+6=8

2 times 2+4=8

3 times 2+2=8

5 times 2-4=6

The 6 is different.

Answer:

The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.

Answer: Choice C.   (3,-2)

A diagram is shown below.

===============================================

Explanation:

There are two approaches we can take. Since we're given a list of choices, we can plug each of the coordinates one at a time into the inequality. If we get a true statement, then it is a solution.

For choice A, we have x = 2 and y = 3 paired up together. Plugging them into the given inequality leads to...

y < (-1/2)*x + 2

3 < (-1/2)*2 + 2

3 < -1 + 2

3 < 1

This is false because 3 is not smaller than 1. So (2,3) is not a solution. You should find that choice B leads to a similar situation because

y < (-1/2)*x + 2

1 < (-1/2)*2 + 2

1 < -1+2

1 < 1

and 1 cannot be smaller than itself. So (2,1) isn't a solution either.

However, choice C is the answer since,

y < (-1/2)*x + 2

-2 < (-1/2)*3 + 2

-2 < -1.5 + 2

-2 < 0.5

This is true because -2 is to the left of 0.5 on the number line. So that's why (3,-2) is a solution.

For choice D, you should find that (-1,3) doesn't make the inequality true.

-----------------------------------------------------------

An alternative approach:

As a visual way to solve this problem, we can graph the given inequality by following these steps

We make the boundary line dashed because points on the boundary do not count as solution points. This is due to the lack of "or equal to" in the inequality sign. We shade below the boundary line because of the "less than".

As the diagram below indicates, the blue region consists of every (x,y) solution point that makes y < (-1/2)*x + 2 true.

The diagram also shows that only point C is in that blue region, making it a solution point. Point B on the boundary does not count as a solution. You can think of the dashed line as an electric fence you can only get closer to, but can't touch, in terms of determining a solution point.

So effectively, this is a quick and easy way to find solutions if you have a graphing calculator or online graphing tools (such as Desmos or GeoGebra).

Answer:

Area=15in²

Perimeter=16in

Step-by-step explanation:

area=L×W

Perimeter=L+L+W+W

Answer:

Your answer is

Area  =  ( 5 * 3) = 15 inch ^2

Perimeter = 2(5+3) = 16 inch
