Answer:

Step-by-step explanation:

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

Answer:

x = -2

Step-by-step explanation:

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

Answer:

3x^2-4x+12

Step-by-step explanation:

x(2x+3)+(x-3)(x-4)

2x^2+3x+x^2-3x-4x+12

2x^2+x^2+3x-3x-4x+12

3x^2-4x+12

Answer:

3x² -4x + 12

Step-by-step explanation:

x(2x + 3) + (x - 3)(x - 4)

= 2x² + 3x + x² - 4x -3x + 12

= 3x² -4x + 12

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.

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

Answer:

Step 1: multiply

10*10=100*10=1000*10=10000

Step 2: write 1st one out.

(8*10000)

Step 3: multiply

8*10000=80000

________________-

Step 1: multiply

10*10=100*10=1000*10=10000*10=100000*10=1000000*10=10000000*10=100000000*10=1000000000*10=10000000000*10=100000000000*10=1000000000000

step2: multiply

2*100000000000=200000000000

step 3: write it out

80000*200000000000

step 4: solve

80000*200000000000=1.6 to the power of 17

Step-by-step explanation:

so your answer is

1.6 to the power of 17

that was a lot yw

Answer:

The answer is no because 5 is greater than 3

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]

Answer:

36 inches²

Step-by-step explanation:

[tex]A=bh[/tex] where b is the base length and h is the height

The base length of the parallelogram is 12 inches and its height is 3 inches. Plug these values into the equation.

[tex]A=(12)(3)\\A=36[/tex]

Therefore, the area of the figure is 36 inches².

I hope this helps!

Answer:

yes the answer is 36in. Which mean the person is right too

Step-by-step explanation:

sum of all angles should equal 180

Answer:

I certainly can't help you

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

Answer:

11. None of the above

12. 7

Step-by-step explanation:

11. Through exhaustion (Just trying them all) none of them worked and therefore can be ruled out.

12. 12 / 2 = 6 (6 granola bars per box)

42 / 6 = 7 (7 boxes needed to make up 42)

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:

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

Answer:

The answer is 91 bags.

Step-by-step explanation:

You divide 45.5 by 0.5

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.
