Step-by-step explanation:

2x + y = 7,  y is a function of x

Explanation:

2x + y = 7 is a function

===================

Rewrite into slope intercept form

y = 7 - 2x

y = -2x + 7

The vertical line touches the graph only one time. Thus y is a function of x.

Answer:

Given equation:  [tex]2x+y=7[/tex]

Definition of a function

The given function is in the standard form of a linear equation: [tex]ax+by=c[/tex]

If the given equation is rearranged to make y the subject:

[tex]y=-2x+7[/tex]

it is now in the general form of a linear equation, [tex]y=mx+b[/tex] (where m is the slope and b is the y-intercept).

A linear equation is one of a straight line, and so, by definition, each value of y corresponds to one value of x.  Therefore, this is a one-to-one function.

Answer:

option C

Step-by-step explanation:

area of rectangle = length * width

12x^2 - 5x - 3 = (4x - 3) * width

12x^2 - 9x + 4x - 3 = (4x - 3)* width

3x(4x - 3) + 1(4x - 3) = (4x - 3)*width

(3x + 1)(4x - 3) / (4x - 3) = width

3x + 1 = width

Answer:

5 feet

Step-by-step explanation:

So you know the cross-sectional area of the circle at the bottom of the cylinder is 28 square feet and you are told the volume of the cylinder is 140 cubic feet which means the height must be 5 feet as the 28 square feet must continue going up to fill the 140 cubic feet.

Answer:

4 Nickles

Step-by-step explanation:

to find this out we can devide the total cost (20 ¢) by the worth of the coin we are using (1 Nickel = 5 ¢) as shown below

20 ÷ 5 = 4

what this equation shows is that 4 nickels are needed to add up to a total of 20 ¢

hope this helps

side note, i dont usually say this but at the moment i am 2 crowns away from my next level, so if the answer seems fit to you a crown would be, depending on the other answer, thank you

EDIT:
Additional Example

this method can be applied to most situations, even if you need multiple coin types

say Ron wants to buy a 57 ¢ apple pie slice in exact change, lets assume he has a surplus in the four common coins in his wallet book or pocket

first he uses a quarter and divides as follows

57 ÷ 25 = 2 with a remainder of 7

then he can take a coin of less value then the remainder (in this case a nickel since 5 < 7, and not a dime since 10 > 7)

7 ÷ 5 = 1 with a remainder of 2

and finally with the pennies

2 ÷ 1 = 2

with this info we know that Ron will need 2 quarters, 1 nickel and 2 pennies to have exact change in the least amount of coins

Answer:

8%

Step-by-step explanation:

8 out of 100 are green

8/100  * 100% = 8 %

Answer:

8% of the beads are green

Step-by-step explanation:

Step 1:  Determine what percentage of the beads are green

This problem is known as a probability problem which basically tries to determine the proportionality between certain numbers.  In this example we are trying to figure out the proportionality between the green beads and the total sample.  

(8 green beads) / (100 total beads)

0.08

0.08 is the probability but if we want to determine what the percentage is of the number we just multiply it by 100.

0.08 * 100 = 8%

Answer:  8% of the beads are green

The equation of function g(x) is g(x) = 2(x -7)² - 1, and the values of h and k are 7 and -1, respectively

The function is given as:

f(x) = 2x² - 1

When the function is translated 7 units left, the transformation rule is:

(x,y) -> (x + 7, y)

So, we have:

g(x) = 2(x -7)² - 1

A quadratic function is represented as:

g(x) = a(x -h)² + k

By comparison, the values of h and k are 7 and -1, respectively

Answer:

20079.05 cm^2,

Step-by-step explanation:

Surface area of the box without the lid

=  90*42 + 2(90*34) + 2(42*34) = 12756.

Now find Surface area of the half cylinder:

The diameter of the 2 half circles = 42 so the radius = 21.

The area of the lid  

= 2 + 1/2 π (21)^2 + π r * 90

= 7323,052

Total = 20079.052

Answer:105

Step-by-step explanation:

area of rectangle (b*h) (7*12)

Area of triangle 1/2 (b*h) 1/2(7*6)

Rectangle=84

Triangle=21

84+42= 105

Answer:

105

Step-by-step explanation:

Well, this figure, as you can see, is made of two figures - a triangle and a rectangle.

To find it's area we will find the areas of the triangle and the rectangle separately and then sum them. I hope you get why we do that.

So, let's start with the rectangle.

The area of the rectangle is very easy to find simply just multiply the lenghts of its two sides:

A1 = 7 * 12 = 84

Now, the triangle.

You can see that one of the smaller sides of the rectangle is equal to 7. The side in front of it is also 7. Notice that this side is also equal to one of the sides of the triangle, its base.

So from the figure we can tell that the base of the triangle is equal to 7, we are also given its height.

There is a formula we can use here to find the area. The area of a triangle is equal to its base (a) multiplied by the height(h) and divided by 2. I'll call the area of the triangle A2.

We know the height

h = 6

I hope you noticed that we also know the base

a = 7

So we just use the formula:

A2 = (6 * 7) / 2 = 42 / 2 = 21

Now that we have the areas of the two figures, A1 and A2, all we have to do is to sum them to find the area of the big one.

So, let's do it:

A = A1 + A2

A = 84 + 21 = 105
