Answer:

Step-by-step explanation:

A quadratic equation must contain

an [tex]x^{2}[/tex] term

and must not contain terms with degrees higher than [tex]x^{2}[/tex].

A non/not quadratic equation doesn't have an [tex]x^{2}[/tex] term. It also features a term such as [tex]x^{3}[/tex] which isn't allowed in quadratic equations

Answer:

A quadratic equation contains a quadratic term (x²), as per the name. The quadratic term must be any variable squared. A non-quadratic equation is an equation that does not contain a quadratic term such as x².

The format for a quadratic equation should look like so: ax² + bx + c = 0, in which a, b, and c are all real numbers and a cannot be equivalent to 0. An example of a quadratic could be: 5x² + (-3x) + 5 = 0.

An example of a non-quadratic equation could be: x³ - 81 = 0.

Answer:

Linear

Step-by-step explanation:

The y is increasing constantly by 5 each time. The equation that would represent this is y=5x-7 because when x is 0 y is -7, so that is your y intercept, and the m, or slope, of your graph is 5, because of the constantly increasing y.

The given  table is representing linear function. So Option B is correct.

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Given that,

A table

x   0    1    2    3    4    5  

y   -3   5   13  21   29  37

Lets us first check that data for linear relationship,

Consider a function,

y = mx + c

lets put value (0, -3)

-3  = m0 + c

c = -3

y = mx -3

Now putting second point

5 = mx1 -3

m = 8

y = 8x - 3

If third point satisfies the given condition

then it will be linear function

x = 2 & y = 13

y = 8x -3

13 = 8x2 - 3

13 = 13

hence proved

Thus, the given table represents the linear function.

Answer:

Part A: The time it will take for both of them to painted equal number of feet is 4.875 minutes

The number of feet Benito will have painted when the two sides have equal length is 73.125 feet

Part B: It is not true that Tyler will finish painting his side of the fence before Benito finishes painting his

Part C: Time to rest is 1.864 minutes

Step-by-step explanation:

The given information are;

The length of fence Tyler already painted when Benito started = 19 ¹/₂ feet

Benito paints 15 feet/minute

Tyler paints 11 feet/minute

Length of fence = 150 feet

Part A:

The time it will take for both of them to painted equal number of feet is given as follows;

11×t + 19.5 = 15×t

4×t = 19.5

t = 19.5/4= 4.875 minutes

The time it will take for both of them to painted equal number of feet = 4.875 minutes

The length Benito will have painted when the two sides have equal length = 15 × 4.875 = 73.125 feet

Part B: The time it will take Tyler to finish painting his side of the fence is given as follows;

11 × t + 19.5 = 150

t = (150 - 19.5)/11 ≈ 11.864 minutes

While the time it will take Benito to finish painting his side of the fence is given as follows;

15 × t  = 150

t = 150/15 ≈ 10 minutes

Therefore it is not true that Tyler will finish painting his side of the fence before Benito finishes painting his

Part C: Given that Benito finishes before Tyler, the length of time Benito gets to rest is given as follows;

Time to rest = Time Tyler takes to finish - Time Benito takes to finish

Time to rest = 11.864 - 10 = 1.864 minutes.

Answer:

C. Nonvertical parallel lines will have the same slope but different​ y-intercepts.

Step-by-step explanation:

Parallel lines never intersect, so they must have the same slope. The reason why option A is incorrect is because if they had the same y-intercept, they would be considered the same line directly on top of each other, and parallel lines never touch. :)

Nonvertical parallel lines will have the same slope but different​ y-intercepts. Then the correct option is C.

When the distance between the lines is constant then the lines are called parallel lines. The lines do not intersect when they are separated from each other. And the slope of the lines is equal.

Let the equation of the line be ax + by + c = 0. Then the equation of the parallel line that is parallel to the line ax + by + c = 0 is given as ax + by + d = 0.

The slope of the parallel line will be congruent. And the product of the slopes of the perpendicular lines will be negative 1.

Nonvertical parallel lines will have the same slope but different​ y-intercepts. Then the correct option is C.

102-105

Step-by-step explanation:

Median formula for a group data is expressed as shown;

Median = (N+1)/2 th value/interval

N is the total number of students

From the question N = 36

Median = (36+1)/2

Median = 37/2

Median = 18.5

Therefore we are to cumulate the value of the frequency up till the 18.5th value.

From the table

If we keep cummulating the frequency from the top;

Let's add:

1+3+5+5+8 = 21

Since the 18.5th values falls within the cumulative frequency value (i.e 21), the corresponding interval where we stopped cumulating will be our Median.

From the table, the interval with the frequency of 8 is 102 - 105. Hence the median is located at the interval 102 - 105

Answer:

The degree of f(x) is even and the leading coefficient is positive. There are 3 real zeros and 2 relative minimum values.

Step-by-step explanation:

We have the graph of f(x).

In general, remember these points:

For even-degree functions:

And for odd-degree functions:

P.S. Yes, it's a lot. But grasping these concepts will help you greatly in future mathematics!

Anyways, let's go back to our problem. Our graph has the same end behavior, so it must be an even function.

Moreover, both end behavior are approaching positive infinity, so the leading coefficient must be positive.

The real zeros of a function are whenever the graph touches or crosses the x-axis. We see that it happens only three times (this is circled in blue below in the image).

The relative minimum values are whenever the graph reaches its lowest point between an increasing and decreasing (or decreasing and increasing) curve. This happens twice (this is circled in black below in the image).

Note: The black arrows denote whether the graph is increasing or decreasing (down means decreasing, up means increasing).

So, you can see that our minimums will always be between a decreasing and then an increasing curve.

So, our solution is:

The degree of f(x) is even and the leading coefficient is positive. There are 3 real zeros and 2 relative minimum values.

And we're done!

Step-by-step explanation:

A store has a 20% sale on everything.

So since you are saving 20%, you will only be paying 80% of the original price.

To find the sale price use the following formula:

Sale price = 80% x original price

They told us the original price = 350 AED

This means:

Sale price = 80% x 350

I think it would be easiest to change 80% into a fraction if you don't have a calculator :)

80% = [tex]\frac{80}{100} = \frac{4}{5}[/tex]

This means that the
