Answer:

-44

Step-by-step explanation:

Since a is -2 and y equals 7 we can plug them both into the expression to get -2 - 6(7) which after simple math results in the answer of -44.

Answer:

30.5

Step-by-step explanation:

Let ;

Sunny = S ; Medium = M ; Cold = C

_____ S _____ M ___ C

__X : 50 ____ 35 ___ 10

P(X) : 0.2 ____ 0.5 __ 0.3

P(M) = 1 - (0.2 + 0.3)

P(M) = 1 - 0.5 = 0.5

Expected profit per day, E(X)

E(X) = sum of (X * p(x)

E(X) = (50 * 0.2) + (35 * 0.5) + (10 * 0.3)

E(X) = 10 + 17.5 + 3

E(X) = 30.5

Answer: A: (6, 5)

Step-by-step explanation:

When graphing a system of equations, you can find the solution by finding where the graphs intersect. In this case, the graphs intersect at (6, 5).

To verify that this is indeed a solution to the system of equations, we can substitute (6, 5) into both of the given equations:

[tex]y = \frac{1}{2}x + 2[/tex]

[tex]5 = \frac{1}{2} * 6 + 2[/tex]

[tex]5 = 3 + 2[/tex]

[tex]5 = 5[/tex]

[tex]y = x - 1[/tex]

[tex]5 = 6 - 1[/tex]

[tex]5 = 5[/tex]

Since both equations hold true when plugging in the given coordinate (6, 5), we know that this is a solution to the system of equations.

Answer:

150 square centimeters

Step-by-step explanation:

Area of a triangle:

The area of a triangle is the multiplication of 0.5, the base length and the height length.

What is the area of a triangle having a height of 20 centimeters and a base length of 15 centimeters?

[tex]A = 0.5*20*15 = 10*15 = 150[/tex]

The area of the triangle is 150 square centimeters.

Answer:

the first mixed number is 1 8/10 which is reduced to 1 and 4/5 and the seconde is 2 and 3/5 added equals 4 and 2/5

Step-by-step explanation:

1 plus 2 equals 3

and 3/5 plus 4/5 equals 7/5

turn it into a mixed number which equals 1 and 2/5 the add 3 and u get 4 and 2/5

Answer:

1. 3x-7y and -7y+3x

Step-by-step explanation:

1. 3x -7y and -7y +3x

This is correct because the terms remain unchanged. The -7y stays a -7y and the positive 3x stays a positive 3x.

2. 3x -7y and 7y -3x

This is not correct because the signs of the 3x and 7y switch. For the expressions to be equivalent, the signs must remain unchanged.

3. 3x -7y and 3y -7x

This is not correct because the variables of the 3 and 7 switched. The variables need to stay the same, for the expressions to be equivalent.

4. 3x-7 and -3y+7x

This is not correct because both the variables and the signs of the expressions changed. Both the signs and variables would need to stay the same in order to be equivalent.

The ordered pair does not lie on the graph of the exponential function

is (12, 0).

Option A is the answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To check whether an ordered pair lies on the graph of the exponential function f(x) = [tex]3(1/4)^x,[/tex]

We need to substitute the values of x and y into the function and see if the equation holds true.

A. (12, 0)

Substituting x = 12 and y = 0 into the function, we get:

[tex]f(12) = 3(1/4)^{12} = 0.000002861[/tex]

This does not equal y = 0, so (12, 0) does not lie on the graph of the function.

B. (-2, 48)

Substituting x = -2 and y = 48 into the function, we get:

[tex]f(-2) = 3(1/4)^{-2} = 48[/tex]

This does not equal y = 48, so (-2, 48) does lie on the graph of the function.

C. (2, 3/16)

Substituting x = 2 and y = 3/16 into the function, we get:

[tex]f(2) = 3(1/4)^2 = 3/16[/tex]

This equals y = 3/16, so (2, 3/16) does lie on the graph of the function.

D. (0, 3)

Substituting x = 0 and y = 3 into the function, we get:

[tex]f(0) = 3(1/4)^0 = 3[/tex]

This equals y = 3, so (0, 3) does lie on the graph of the function.

Therefore,

The ordered pair does not lie on the graph of the exponential function

is (12, 0).

Answer:

59

Step-by-step explanation:

16 + 4 + (42-3) = 59. Do parentheses first. (42-3) = 39. Which changes the equation to 16 + 4 + (39). 39 + 4 = 43. Then the equation changes to 16 + 43. These added together equal 59. Hope this helps!

Answer:

  inverse

  y = 10/x

Step-by-step explanation:

Inverse variation is described by an equation of the form ...

  y = k/x

The value of k is a constant equal to ...

  k = xy = 5·2 = 10·1 = 15·2/3 = 20·1/2 = 10

__

Here, the products of the x- and y-values are all 10, so the inverse variation equation is ...

  y = 10/x

Answer:

I'm pretty sure it's 4.3?

Step-by-step explanation:

Because you divide the larger triangles side first because you are figuring out the scale factor of the small triangle to the larger triangle, not the other way around.

Sorry if i'm wrong

Answer:

first, find the area of the small triangle: 3 times 3 equals 9 divided by 2 equals 4.5.

second, find the area of the big triangle: 13 times 13 equals 169 divided by 2 equals 84.5.

Find difference: 84.5 minus 4.5 equals 80
