Answer:
7 and 3
Step-by-step explanation:
We know that all 4 sides have to add up to 20 and that 2 of the sides are the same because it's a rectangle. To find the area, we have to do length times width. Two different sides have to equal 21 when multiplied. The factors of 21 are 1, 3, 7, and 21. Let's try 1 and 21. We need an area of 21. 1 x 21 = 21 so it satisfies that. Now let's find the perimeter.21 + 21 + 1 + 1 = 44, but we need an perimeter of 20. Now, let's try 7 and 3. 7 x 3 = 21, so it satisfies the area. 7 + 3 + 7 + 3 = 20, so it also satisfies the perimeter. Therefore, 7 and 3 are the dimensions of the table.

1. Solve the simultaneous equations 3x - 2y = 4and 2x + 3y = -6 using elimination method.
Answer:
Multiply the first equation by 2
2(2x+y=5) to get 4x + 2y = 10
add the second equation 3x-2y=4
4x + 3x + 2y + -2y = 10 + 4
7x = 14
x = 2
...
Multiply the first equation by 3 and the second equation by -2 then add
3(2x+y=5) to get 6x + 3y = 15
-2(3x-2y=4) to get -6x + 4y = -8
add them
6x + -6x + 3y + 4y = 15 + -8
7y = 7
y = 1
...
x = 2 , y = 1
(2, 1) is the solution
...
check
2(2) + 1 = 5
4 + 1 = 5
5 = 5
Correct
Hope it helps

2. Consider the following system of equations.
y = 2x - 4
y = -x + 5
{
a. Identify the slope and y-intercept of the graph of each equation.
b. Based on your answer for part (a), are the graphs of the two lines intersecting lines, the
same line, or parallel lines? Explain your reasoning.
Answer:
see below
Step-by-step explanation:
a.
first equation: slope = 2, y intercept = (0,4)
second equation: slope = -1, y intercept = (0,5)
b.
They are intersecting lines. They don't have the same slope so they aren't parallel and they obviously aren't the same equation so they aren't the same line.
M,p, and z represent the lengths of the three sides of this right triangle. Select all the equations that represent the relationship between m,p, and z .
Answer:
The equations are:
[tex]m^2 = p^2 + z^2[/tex] [tex]m^2 = z^2 + p^2[/tex]
[tex]z^2 + p^2 = m^2[/tex] [tex]p^2 + z^2 = m^2[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Select all true equations
From the attachment:
[tex]m = hypotenuse[/tex]
[tex]p\ and\ z = other\ legs[/tex]
Using Pythagoras theorem:
[tex]m^2 = p^2 + z^2[/tex]
This can be rewritten as:
[tex]m^2 = z^2 + p^2[/tex]
or
[tex]z^2 + p^2 = m^2[/tex]
or
[tex]p^2 + z^2 = m^2[/tex]

2/5 divided by 3/4
9/4 divided by 3/4
-5/7 divided by 1/3
-5/3 divided by 1/6
2/5 ÷ 3/4 = 8/15
9/4 ÷ 3/4 = 3
-5/7 ÷ 1/3 = -15/7
-5/3 ÷ 1/6 = -10
5 points A farmhouse shelters 10 animals. Some are goats and some are ducks. Altogether there are 36 legs. How many ducks and goats are there?
Answer:
2 ducks and 8 goats
Step-by-step explanation:
let goat be g
let duck be d
d + g = 10
ducks have 2 legs, 2d
goats have 4 legs, 4g
2d + 4g = 36
making d the subject in the first equation;
d = 10 - g
put in second equation
2(10 - g) + 4g = 36
20 -2g + 4g = 36
2g = 36 - 20
2g = 16
g = 8
if g is 8
d = 10 - 8
d = 2

Step-by-step explanation:
14. K' = x + a, y + b
= -1 + 2, 6 + 3
K' = 1, 9
K" = (x, y) → (-x, y)
= (1, 9) → (-1, 9)
K" = -1, 9
15. D. Octagon
Since it has 8 angles, of 360 ° is divided by 8 angles, then each corner has an angle of 45 °
16. P' = x + a, y + b
= -2 + 6, 4 + 5
P' = 4, 9
17. H' = x + a, y + b
= 5 + 10, 4 + (-11)
= 15, -7
18. A (6, -1)
A' = (x, y) → (x, -y)
= (6, -1) → (6, -(-1)
= 6, 1
19. J' = x + a, y + b
= -2 + (-3), 1 + (-3)
= -5, -2
J" = (x, y) → (x, -y)
= (-5, -2) → (-5, -(2))
= -5, -2

A construction company can remove 3/3/4 metric tons of dirt from a construction site in 1/1/8 hours what is the unit rate in metric tons per hour write your answer as a fraction or a mixed number in simplest form
Answer:
3 1/3 metric tons per hour
Step-by-step explanation:
To find the unit rate, divide 3 3/4 metric tons by 1 1/8 hours (notice that the correct format is 3 3/4, not 3/3/4).
3 3/4 metric tons 3.75 metric tons
---------------------------- = --------------------------
1 1/8 hours 1.125 hours
It's easier to deal with decimal fractions here than with proper fractions.
The unit rate then comes out to be 3.75/1.125 metric tons per hour, or
3.33333 metric tons per hour, or 3 1/3 metric tons per hour

Which of the following functions has a graph with a vertex that is a translation 5 units horizontally to the right of the vertex of the graph of g(x) = (x + 2)2 + 2?
Answer:
g(x) = (x -3 )^2 + 2
Step-by-step explanation:
f(x) = (x + 2)^2 + 2
We want to shift this 5 units to the right
The parabola is written in the form
y = a(x-h) ^2 +k where (h,k) is the vertex
The vertex is at ( -2, 2)
We want to shift it 5 units to the right
-2+5 = 3
g(x) = (x -3 )^2 + 2
Answer:
g'(x) = (x-3)² + 2
Step-by-step explanation:
g'(x) = (x+2 - 5)² + 2

I didn't pay attention in class for a few days and now I'm lost. if somebody could at least explain proportions I would be very thankful.
Answer:
A proportion is a comparison of two numbers that each represent the parts of a whole. Essentially, a proportion says that two fractions are the same, even if the amount is different. For example, 1/2 of 10 marbles is the same proportion as 1/2 of 50 marbles.
