Answer:
[tex]-5\:\mathrm{and}\: 11[/tex]
Step-by-step explanation:
We can write the following system of equations:
[tex]\begin{cases}x+y=6\\x-y=16\\\end{cases}[/tex]
Adding both equations together, we isolate [tex]x[/tex] and get:
[tex]2x=22,\: x=11[/tex]
Plugging [tex]x=11[/tex] in any of the equations, we can solve for [tex]y[/tex]:
[tex]11+y=6,\: y=-5[/tex]
Verify that the solution pair [tex](11, -5)[/tex] works [tex]\checkmark[/tex]
Therefore, the two numbers are [tex]\fbox{$-5\:\mathrm{and}\: 11$}[/tex].

Answer:
a). Yes. Area will be less than 100 square in.
b). Area of octagon = 82 in²
Step-by-step explanation:
From the picture attached,
a). Octagon is inscribed in a square having one side = 10 inches.
Since, octagon is obtained by cutting off the four equal corners of the square,
Area of octagon will be less than the area of the square.
Area of square = (side)²
= 10²
= 100 in²
Therefore, area of octagon will be less than 100 in²
b). Since, corner cut off from the square are equal in shape and area,
Area of one corner (right angle triangle) = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(3)(3)[/tex]
= 4.5 in²
Area of 4 corners = 4.5 × 4 = 18 in²
Area of octagon = Area of square - Area of 4 corners removed
= 100 - 18
= 82 in²

Activity
In this activity, you will create a function from two points that satisfy it.
A linear function passes through the points (-2,3) and (-3,5). Complete the following tasks to find the equation of the function.
Part A
To find the equation, first find the rate of change. What is the rate of change for the linear function that passes through the two points?
Answer: The line representing the function has its y-intercept at 40. So, the initial value of the function graphed is 40.
Step-by-step explanation:
The equation of the line passing through the points (-2,3) and (-3,5) will be 2x + y + 1 = 0 and the rate of change is negative 2.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

hiii please help! i’ll give brainliest if you give a correct answer tysm!
Answer:
1/5
Step-by-step explanation:
The volume is found by multiplying the height, width, and length. So to find the height, you need to divide 1/100 by 1/4 and 1/5.
1/100 divided by 1/5 = 1/20
1/20 divided by 1/4 = 1/5

Step-by-step explanation:
Michelle lives 4.5 miles from work. Kelly lives 5.6 kilometers from work. Staci lives 4,200 meters from work. Kyle lives 670,000 centimeters from work.
Answer:
Michelle < Staci < Kelly < Kyle
Kyle is the greatest distance from work, while Michelle is the closest to work.
Step-by-Step Explanation:
1 kilometer = 0.62137119 mile(s)
4.5 miles = 0.62137119 × 4.5 = 2.79617036 kilometers
4,200 meters = 4.2 kilometers
670,000 centimeters = 6.7 kilometers
So,
Michelle = 2.8 kilometers (rounded up)
Kelly = 5.6 kilometers
Staci = 4.2 kilometers
Kyle = 6.7 kilometers
So,
Michelle < Staci < Kelly < Kyle
Kyle is the greatest distance from work, while Michelle is the closest to work.

Kieran, Jermaine and Chris play football.
Kieran has scored 8 more goals than Chris.
Jermaine has scored 5 more goals than Kieran.
Altogether they have scored 72 goals.
How many goals did they each score?
Step-by-step explanation:
Find an equation that explains the problem. We can see how many goals the players have scored in comparison to each other. The person with the fewest goals is Chris. Let us say he score x goals. Then we can see that Kieran has scored 8 more than Chris, i.e. x + 8. Jermaine scored 5 more goals than Kieran, therefore x + 8 + 5 = x + 13. Now we have the amount of goals each person scored relative to each other. The total number of goals scored was 72, thus all of these amounts must equal 72.
x + (x + 8) + (x + 13) = 72
Now we can rearrange and solve for x.
3x + 21 = 72
3x = 51
x = 17
3(x+4) what is this question?
Answer:
Step-by-step explanation:
3×x+4×3
3x+12
Answer:
Step-by-step explanation:
The first step would be to multiply out the bracket. So, using this example we would times each item inside the bracket by 3.
As a result we would get: 3x + 12 = 18
Then we would need to move the 'x' value to one side of the equation and the rest of the equation to the other side. To move '12' onto the other side of the = sign we need to subtract 12 from both sides.
This would then bring us to: 3x = 6
Finally, to find the value of 'x' we then need to divide both side of the equation by 3.
Resulting in the final answer of x = 2
Solve the system of linear equations by elimination.
-3.x – 5y = -7
-4x + 5y = 14
Answer:
(- 1, 2 )
Step-by-step explanation:
Given the 2 equations
- 3x - 5y = - 7 → (1)
- 4x + 5y = 14 → (2)
Add the 2 equations term by term to eliminate y , that is
- 7x + 0 = 7
- 7x = 7 ( divide both sides by - 7 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
- 3(- 1) - 5y = - 7
3 - 5y = - 7 ( subtract 3 from both sides )
- 5y = - 10 ( divide both sides by - 5 )
y = 2
solution is (- 1, 2 )
Answer:
( -1, 2)
Step-by-step explanation:
Since this is asking for elimination, you will need to line up x or y to be the opposite amount:
-3x -5y = -7
-4x + 5y = 14
(notice -5y and 5y are already opposite, therefore no further actions are needed to line them up.)
Next step is to add both equations up to eliminate y and to find x:
-7x = 7
x = -1
After finding x, plug the x back into either one of the equations to solve for y. If you are unsure, you can plug it into the other equations to double check.
If you chose to do equation 1:
-3(-1) -5y = -7
3 -5y = -7
-5y = -10
y = 2
If you chose to do equation 2:
-4(-1) + 5y = 14
4 + 5y = 14
5y = 10
y = 2
After finding x and y, you will find the point ( -1, 2)

Tan A=
Answer:
The value of tan A: 40/9
i.e.
tan A = 40/9
Step-by-step explanation:
Given
Hypotenuse = 41
To determine
m ∠ A = ?
Using the trigonometric ratio
tan A = opposite / adjacent
Here:
Opposite of m ∠ A = 40Adjacent of m ∠ A = 9Thus, substituting opposite = 40 and adjacent = 0 in the equation
tan A = opposite / adjacent
tan A = 40/9
Therefore, the value of tan A: 40/9
i.e.
tan A = 40/9

A factory produces 80,000 candies each day. They produce equal quauntities of four flavors cherry lemon orange and strawberry. The candies are mixed together during packaging . What is the probabillity that a randomly selected cany is orange
Answer: [tex]\dfrac14[/tex]
Step-by-step explanation:
Given: The factory produces equal quantities of four flavors cherry lemon orange and strawberry.
Let orange candy= cherry = lemon = strawberry = x
Total candies = x + x + x + x= 4x
The probability that a randomly selected candy is orange = [tex]\dfrac{x}{4x}=\dfrac14[/tex]
Hence, the probability that a randomly selected candy is orange = [tex]\dfrac14[/tex]

FIND m
Answer:
Angle R is equal to 35 and DE is equal to 48
Step-by-step explanation:
In similar triangles, like these, the angles will always be the same to its correspondent. Angle E in the other triangle is 35 degrees so R, its corresponding angle, will be the same. So therefore R is 35.
This is not the same case for sides. There will always be a ratio between both triangles. The ratio in this case is 1.2 to 1. So multiply RP (DE's corresponding side), by 1.2. You will get 48. So therefore DE is equal to 48.
