Answer:

1) x=6, y=-6 which is (6,-6) as an ordered pair

3) x=10, y=-1 which is (10,-1) as an ordered pair

Step-by-step explanation:

Question 1:

Solve them like an addition problem:

-4x-2y=-12

4x+8y=-24

________

(-4x+4x)+(-2y+8y)=(-12+-24)

0x+6y=-36

6y=-36

y=-6

Plug value of y into one of the original equations:

4x+8(-6)=-24

4x-48=-24

4x=24

x=6

Question 3:

Solve them like an addition problem:

x-y=11

2x+y=19

_______

(x+2x)+(-y+y)=11+19

3x+0y=30

3x=30

x=10

Plug value of x into one of the original equations:

10-y=11

-y=1

y=-1

Answer:

Smaller than

Positive numbers

Step-by-step explanation:

The absolute value of a number is the distance from the zero. This can be positive or negative forming the absolute number. The distance is negative when the number is positive. The absolute numbers are used in the equations for the solutions. The numbers greater than zero are positive numbers.

Answer:

No. If the second positive integer is larger than the first positive integer in a subtraction problem, the difference will be negative.

Answer:

x = 114°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus

x + 18° = 132° ( subtract 18° from both sides )

x = 114°

The value of angle x in the triangle will be equal to 114°.

When one side of a triangle is extended, an external angle of the triangle is created. The external angle of the triangle is the non-straight angle (the one that is not simply the extension of the side) that is outside the triangle but close to an interior angle.

Given that a side of the triangle below has been extended to form an exterior angle of 132°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus

x + 18° = 132° ( subtract 18° from both sides )

x = 114°

Therefore, the value of angle x in the triangle will be equal to 114°.

Answer:

The correct option is;

{10, 11, 12, 13. or 14}

Step-by-step explanation:

The given function for the total cost, c, to create calendars is c = 5.5u + 25

The domain of a function are the values of the input variables of the function with which the output (the values) of the function are found

Therefore, the domain of the given function are the values of the variable, u, in the function

Where;

u = The number of calendars made

Answer:

6

Step-by-step explanation:

I hope this helps!

The LCM of 3 and 6 is 6, which is the smallest positive integer that is a multiple of both numbers.

The least common multiple is defined as the least positive integer that is dividable by both given numbers.

A group's Least Common Multiple (LCM) is the smallest number that is a multiple of all the numbers.

We can use the prime factorization method to find the LCM. We can write each number as a product of its prime factors:

3 = 3

6 = 2 x 3

The LCM is the product of the highest powers of all the prime factors.

Here, the highest power of 2 is 2, and the highest power of 3 is 3. So, the LCM is:

LCM(3, 6) = 2 x 3 = 6

Thus, the LCM of 3 and 6 is 6, which is the smallest positive integer that is a multiple of both numbers.

Step-by-step explanation:

slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

The second y point is 16 and the first is -4, so:

(16) - (-4)

Which can be written as 16 + 4 because a double negative makes a positive. Do the same for the x points, -7 and -3:

(-7) - (-3)

(-7) + (3)

Now solve both of them:

16 + 4 = 20

(-7) + 3 = -4

Remember, the slope formula is y over x, so we still need to put it into the fraction form:

[tex]\frac{20}{-4}[/tex]

You can reduce this to [tex]-\frac{5}{1}[/tex], or 5.

The slope of the line will be "-5".

Given points are:

As we know the formula,

→ Slope, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

By substituting the values, we get

                  [tex]= \frac{16-(-4)}{-7-(-3)}[/tex]

                  [tex]= \frac{16+4}{-7+3}[/tex]

                  [tex]= -\frac{20}{4}[/tex]  

                  [tex]= -5[/tex]

Answer:

A. I only

Step-by-step explanation:

Given the functions

h(x)= -2x - 1 g(x)= -1/2x + 1/2

h(g(x) =h( -1/2x + 1/2)

=f((-x+1)/2)

We are to replace x in h(x) with -x+1/2

h((-x+1)/2) = -2(-x+1)/2 + 1

h((-x+1)/2) = -(-x+1)+1

h((-x+1)/2)= x-1+1

h((-x+1)/2) = x

h(g(x) = x

Also for g(h(x))

g(h(x)) = g(-2x-1)

Since g(x) = -x+1/2

g(-2x-1) = -(-2x-1)+1/2

g(-2x-1) =2x+1+1/2

g(-2x-1) = 2x+2/2

g(-2x-1) = 2(x+1)/2

g(-2x-1) = x+1

Sine g(h(x)) ≠ h(g(x)), hence both functions are not inverses of each other

Hence I. The function h(g(x)) = x is the only correct option. Option A is correct

The correct option is: A. I only

We have functions:

[tex]h(x)= -2x - 1 \\g(x)= -\frac{1}{2} x +\frac{1}{2} \\h(g(x)) =h(-\frac{1}{2} x +\frac{1}{2}) \\h(g(x))=f(\frac{-x+1}{2} )[/tex]

Now, replace x in h(x) by [tex]\frac{-x+1}{2}[/tex]

So,

[tex]h(\frac{-x+1}{2} ) = -2(\frac{-x+1}{2}) + 1\\h(\frac{-x+1}{2} ) = -(\frac{-x+1}{2}) + 1\\h(\frac{-x+1}{2} )= x-1+1\\h(\frac{-x+1}{2} )=x\\h(g(x)) = x[/tex]

Now, g(h(x))

g(h(x)) = g(-2x-1)

Since [tex]g(x) = \frac{-x+1}{2}[/tex]

[tex]g(-2x-1) = \frac{-(-2x-1)+1}{2} \\g(-2x-1) =\frac{2x+1+1}{2}\\g(-2x-1) =\frac{2x+2}{2}\\g(-2x-1) = x+1[/tex]

As g(h(x)) ≠ h(g(x)),

Therefore, both functions are not inverses of each other.

Hence A. I only

The function h(g(x)) = x is the only correct option.

So, option A is correct.

the total amount of animals in McDonald's farm is missing, so I looked for a similar question and found the attached image:

McDonald can earn:

15 cows x $250 = $3,750

2 horses x $250 = $500

20 sheep x $200 = $4,000

25 goats x $200 = $5,000

17 chickens x $50 = $850

total = $14,100

I think it would be 1,200ml or 800 try 1,200ml first

Answer:

Its A. 600 ml.

Step-by-step explanation:

1st. Find the ml of milk for one pancake. So 400 divided by 10, it equals 40ml. So to find how many ml for 15 pancakes...you multiply 15 and 40 ml, and that will give you 600ml needed.

Answer:

1.) x = 110

[tex]\frac{3}{22} =\frac{15}{x}[/tex]

So for 3 to become 15 it would have to be multiplied by 5 because 3 x 5 = 15. And if I multiply the numerator by anything I always have to do the same to the denominator. So I multiply 22 x 5 = x. x = 110

[tex]\frac{3 * 5}{22*5} =\frac{15}{110}[/tex]

2.) x = 72

[tex]\frac{x}{16} =\frac{9}{2}[/tex]

For 16 to become 2 it has to be divided by 8 because 16 ÷ 8 = 2. And I have to do the same to the numerator of course, so i have to find x ÷ 8 = 9. I know the answer by memory, but for some it's easier to rewrite this as 9 × 8 = x. x=72

[tex]\frac{72}{16} =\frac{9}{2}[/tex]

3.) c = 24

[tex]\frac{3}{5} =\frac{c}{40}[/tex]

For 5 to become 40 it must be multiplied by 8 because 5 × 8 = 40. I have to multiply 8 by the numerator as well and 3 × 8 = 24. c = 24

[tex]\frac{3*8}{5*8} =\frac{24}{40}[/tex]
