Answer:
it's actually none of these.
Step-by-step explanation:
if we divide 15 by 3 we also have to divide 42 by 3. We end up with 5:14. 15 isn't divisible by any number other than 1, 3, 5, and 15.

Which point is a solution to the linear inequality y<
-1/2x+2
O (2, 3)
O (2,1)
O (3,-2)
O (-1,3)
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
Draw a dashed line through the points (0,2) and (4,0). This forms the graph of y = (-1/2)x + 2Shade below the dashed lineWe 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).

Step-by-step explanation:
Classify each pair of angles as complementary, supplementary, or neither.
Drag and drop the choices into the boxes to correctly complete the table. Each pair of angles may belong to more than one category.
complementary supplementary neither
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
does anyone know the area and the perimeter of this??
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

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

Ann receives a 4% commission on her sales. Her last paycheck included $196 in commissions. Solve the formula C = 0.04s for s, where C is the amount of commission and s is the amount of sales. Then substitute to find her sales.
A.
$195.96
B.
$196.04
C.
$7.84
D.
$4,900
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

What type of solutions to quadratic equations can be solved by factoring and using the zero product property?
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.

lynn has one red shirt one blue shirt and one yellow shirt to choose from. She also has one blue and one yellow necklace to choose from for work today are these values dependent or independent
I would say the answer is depending. the reason I choose this answer because she chose a random shirt, which she probably chose a necklace that would look best with the shirt she had randomly had choosen.

Solve the following system using the substitution method.you must show ALL work and use the substitution method.
4x+y=14
x-2y=8
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
