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
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
a part of a line with endpoints on both ends a(n):
The answer is line segment
Answer:A part of a line with endpoints on both ends is a(n):
A line with 2 endpoints is called a line segment. We know that it is a segment because the endpoints make the line finite

An insect is standing next to a flower. The insect is 1 cm tall and makes a shadow of 0.5 cm. If the flower makes a 15-cm shadow, how tall is the flower?
Answer:
30 cm
Step-by-step explanation:
set up a proportion of insect height over its shadow equals flower height over its shadow, then cross-multiply
1/.5 = x/15
.5x = 15
x = 30

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]

Answer:
x = 37.5
Step-by-step explanation:
By Basic Proportionality Theorem:
[tex] \frac{x}{20} = \frac{46 - 16}{16} \\ \\ \frac{x}{20} = \frac{30}{16} \\ \\ x = \frac{20 \times 30}{16} \\ \\ x = \frac{600}{16} \\ \\ x = 37.5[/tex]
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

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

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.
glencoe geometry unit 9: whoever can answer the page gets 100 points and brainliest
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

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.
