5.50+0.85x=

The function rule to find the cost to ship a package that weighs [x] ounces is c[x] = 0.85x + 5.5.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is the cost of shipping a package overnight from San Antonio to Dallas, which is $5.50 plus $0.85 per ounce.

We can write -

Fixed cost of shipping overnight = $5.50

Cost per ounce for shipping = $0.85

The function rule that could be used to find the cost to ship a package that weighs [x] ounces will be -

c[x] = 0.85x + 5.5

Therefore, the function rule to find the cost to ship a package that weighs [x] ounces is c[x] = 0.85x + 5.5.

Answer:

The answer is one pair of socks = $10

Step-by-step explanation:

I subtracted 42 by 12 and got 30. I then divided 30 and 3 and got 10.

42-12=30

30/3=10

Or you can subtract 12 from both sides to get the variable on one side. Then you divide the variable by the coefficient (3) and divide 30 by 3 to get 10.

Answer:

-6 * (x+2y=8)

Step-by-step explanation:

1.) lost negative sign  

2.) correct

3.) lost negative sign

-6 * (x+2y=8) = (-6x-12y=-48)

h(x) = -4 + 6

h(x) = 2

h(-2) = 2 because It's a constant function, when you substitute any x-values, you still get the same y-value.

Even if you substitute x = 1000, you still get y = 2.

Therefore, h(-2) = 2

-----------

If you mean h(x) = -4x+6

then h(-2) = 8+6 = 14

therefore, h(-2) = 14 for h(x) = -4x+6

Answer:

y= -3x+6

Step-by-step explanation:

Multiply 3.25*4+3.75= 16.75

Answer:

B

Step-by-step explanation:

First, we can set up an equation to determine how much it will cost for any amount of time greater than one hour.

[tex]c=total cost[/tex]

[tex]h=[/tex] additional hours after the first hour

The equation I came up with is:

[tex]c=3.75+3.25h[/tex]

Now, using the information given to us in the problem, we can solve using this equation. You're using the bike for 5 hours, but since the first hour has a different rent, [tex]h=[/tex] 4.

So,

[tex]c=3.75+3.25(4)[/tex]

[tex]c=3.75+13\\c=16.75[/tex]

The cost of renting a bike for 5 hours is $16.75.

Angle 1 and the angle that is 138 degrees is on the same line. A line is 180 degrees, so you subtract 138 from 180 and you get 42. I hope this helps (:

Answer:

42 degrees

Step-by-step explanation:

every line is 180 degrees, right, so you need to subtract the number you know another angle to find the missing number.

180-138

Given:

The equation of line is

[tex]y=-\dfrac{1}{2}(x-18)[/tex]

The perpendicular line intersect the y-axis at (0,-1).

To find:

Equation of perpendicular line.

Solution:

Point slope form of a line is [tex]y-y_1=m(x-x_1)[/tex], where m is slope.

We have,

[tex]y=-\dfrac{1}{2}(x-18)[/tex]

Thus, the slope of this line is [tex]m_1=-\dfrac{1}{2}[/tex].

Product of slopes of two perpendicular lines is -1.

Let the slope of perpendicular line is [tex]m_2[/tex]. Then,

[tex]m_1\times m_2=-1[/tex]

[tex]-\dfrac{1}{2}\times m_2=-1[/tex]

[tex]m_2=2[/tex]

Slope of perpendicular line is 2 and it passes through (0,-1). So, the equation of perpendicular line is

[tex]y-(-1)=2(x-0)[/tex]

[tex]y+1=2x[/tex]

[tex]y=2x-1[/tex]

Therefore, equation of perpendicular line is [tex]y=2x-1[/tex].
