Which table and graphs represents functions?

Answer:

8 unit difference x, stays the same on y

Step-by-step explanation:

5 to -3 = 8 units

Answer:

x = 10

Step-by-step explanation:

Y = x-5 has a slope of 1

3y - 6x = 0 is a clear linear equation with a Y-intercept of 0

y = -5 has no slope

x = 10 is a line going straight up and intersects the point (10, 0)

Which is an undefined slope

Answer:

2(3x+5) OR (6x+10)

Step-by-step explanation:

8 (2x+3)

8

Answer:

x=-3

Step-by-step explanation:

there are three x's and five one's so the equation is 3x+5

on the other side there are 2 negative x's and 10 negative one's so the equation is -2x-10

set them equal to each other

3x+5=-2x-10

5x=-15

x=-3

Step-by-step explanation:

148 - 68 = 80

80 / 5 = 16

Answer:

true

Step-by-step explanation:

y = ab^x

the coordinates of the point are x and y values.

so, we can express "a" by these values :

k = ab^h

a = k/(b^h) = k × b^-h

now we use this identity in the original equation and get

y = k × b^-h × b^x = k×b^(x-h)

and that is exactly the same as the proposed form.

Answer:

If AB crosses at a right angle, it is called the "perpendicular bisector" of PQ. If it crosses at any other angle it is simply called a bisector. Drag the points A or B and see both types. For obvious reasons, the point F is called the midpoint of the line PQ. See also Angle bisector.

CS = x, and since AB = BC = CD = DA = 1cm -> SD = 1 - x

We see that angle DSP = angle APQ (because they simultaneously equal to 90 when added angle DPS)

So, triangle DSP = triangle APQ (equal hypotenuse - square side and equal angle.)

Similarly, we can prove triangle SCE and QBE in the same way

So, all 4 of the triangles are equal to each other.

-> SD = CE = BQ = AP = 1-x

Calculate the area of 4 triangles : [ x(1-x) : 2 ] x 4 = x(1-x) x 2

Area (PQRS) = 1 - [ x(1-x)] x 2 = 1 - 2x + 2x(squared) = [tex]2x^{2} -2x + 1[/tex]

ii) Half area of PQRS = [tex]x^{2} -x+1[/tex]

= [tex]x^{2} -\frac{1}{2} x-\frac{1}{2} x + \frac{1}{2} = x(x-\frac{1}{2} )- \frac{1}{2}(x-\frac{1}{2} ) + \frac{1}{4} = (x-\frac{1}{2})^{2} + \frac{1}{4}[/tex]

We have : [tex](x-\frac{1}{2}) ^{2}[/tex]

has the smallest value of 0 -> The smallest half value of PQRS = 1/4 -> The smallest value of PQRS = 1/2

Answer:

Step-by-step explanation:

In order to develop a function that models the situation regarding the optimal parameters, the following are needed:

It should be noted that a function simply means the relation or expression that has to do with two or more variables.

In this case, to develop a function that models the situation regarding the optimal parameters, one has to introduce the variables and find an equation relating to the variable.

Answer:

A unit is a measure of ratio between two quantities. In this instance, the unit is a pound. The ratio you need to take is the price of each fruit and divide it by the number of pounds each fruit has to get a price per pound. See below for solution.

Step-by-step explanation:

A. 4.19 dollars / 2.5 pounds = 1.676 dollars / pound

B. 5.49 dollars / 4 pounds = 1.3725 dollars / pound

C. 6.99 dollars / 5 pounds = 1.398 dollars / pound

D. 9.59 dollars / 6.5 pounds = 1.475 dollars / pound

The lowest is B, the apples.

Answer:

f [ x ] = [ x - 3] [ x + 8 ] = x^2 + 5x - 24

Step-by-step explanation:

f (x)=[ x - 3] [ x + 8 ]

x [ x + 8 ] -3[ x + 8 ]

x^2 + 8x - 3x - 24

x^2 + 5x - 24

Answer:

The coordinates (12,7) would NOT be a solution to the system of linear inequalities shown below.

Step-by-step explanation:

If you do the graphing and you look at all your options of coordinates, (12,7) is the only one that is not in the shaded areas or in the lines of the inequalities. Therefore, (12,7) should be the answer to that question. :)

Answer:

x-375

Step-by-step explanation:

First, we find a fourth of $1500.

1/4*1500=375

Then we know that you need to pay $375. We will represent the money right before you pay as x, or any variable you choose.

= x-375

Answer:

Domain: (-∞, -5) (-1, ∞)

Step-by-step explanation:

Note:

For f(x) > 0: See the points of x for which the graph of f(x) lies above the x-axis.

For f(x) < 0: See the points of x for which the graph of f(x) lies below the x-axis.

We need to find the domain of f(x) for which f(x) < 0

From the graph, we can tell:

f(x) < 0 on (-∞, -5) ∪ (-1, ∞)

Therefore: The domain on which the given graph f(x) is negative, is (-∞, -5) ∪ (-1, ∞)

Answer:

C

Step-by-step explanation:

The reason it is C is mainly because it is the only line with a negative slope. A negative slope this direct \. It is not A because that is a positive slope (/). It is not B because that line is undefined which means it would look like this x = 2. And D is wrong because that is a zero slope line which looks like this y = 5. So it is C.

Answer:

{7, 5, 2, 0}

Step-by-step explanation:

The domain is essentially all the [tex]x[/tex] values of the function, where the range is the value of [tex]h(x)[/tex].

So in order to solve this we simply plug in each number into the equation and get:

[tex]h(x)=|-2-5| = |-7|=7[/tex]

[tex]h(x)=|0-5| = |-5|=5[/tex]

[tex]h(x)=|3-5| = |-2|=2[/tex]

[tex]h(x)=|5-5|=|0|=0[/tex]

Therefore the range is: {7, 5, 2, 0}
