Answer:

Answer:

C- The total is $23.27

The 7% tax is $1.52

Answer:

D

Step-by-step explanation:

The vertex is a point where the slope is 0 so opening up the vertex is the minimum so option (D) will be correct.

A graph is a diametrical representation of any function between the dependent and independent variables.

The graph is easy to understand behavior of the graph.

For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.

Vertex is a point where the rate of change or slope of the function is zero.

Since if the slope is zero it means the tangent at that point will be horizontal.

If the parabola opens up then the point where it is changing its direction will be vertex as shown below.

So vertex has a minimum value of y.

Hence "The vertex is a point where the slope is 0 so opening up the vertex is the minimum so option (D) will be correct".

Answer:

21 is the correct answer

Answer:

The three integers are 12,13 and 14

Step-by-step explanation:

Let

x,x+1,x+2 be three consecutive integers.

Out of these, the smallest one is x and largest is x+2 as it comes at last in the integers.

So according to given statement

[tex]x+(x+1)+(x+2) = 4x-9[/tex]

This is a linear equation in one variable, which can simply be solved by using equality properties

[tex]x+x+1+x+2 = 4x-9\\3x+3 = 4x-9[/tex]

Subtracting 4x from both sides

[tex]3x+3-4x = 4x-9-4x\\-x+3=-9[/tex]

Subtracting 3 from both sides

[tex]-x+3-3 = -9-3\\-x = -12\\x = 12[/tex]

The smallest integer is 12.

The other integers are:

x+1 = 12+1 = 13

x+2 = 12+2 = 14

Hence,

The three integers are 12,13 and 14

Answer:

logarithmic scale

The student might be able to graph these results clearly by taking the log of the values.

For given question,

A student has a range of values from 0.000001 to 1,000,000

We need to find the way so that the student will be able to graph these results.

We can write  0.000001 as [tex]1\times 10^{-6}[/tex]

[tex]\Rightarrow 0.000001=10^{-6}[/tex]

and 1,000,000 as [tex]1\times 10^6[/tex]

[tex]\Rightarrow 1,000,000=10^6[/tex]

If we take the log of these range values, then it would be,

[tex]\Rightarrow log(10^{-6})=-6[/tex]

and [tex]log(10^6)=6[/tex]

This means, the student might be able to graph these results clearly by taking the log of the values.

Answer:  7.2 + L= 19.5

Answer:

Slope: [tex]\frac{7}{2}[/tex]

Y-intercept: (0, 2)

Step-by-step explanation:

7x = 2y - 4

-2y = -7x - 4

y = [tex]\frac{-7}{-2}[/tex] x - [tex]\frac{4}{-2}[/tex]

y = [tex]\frac{7}{2}[/tex] x + 2

The slope is always the coefficient of x and the y-intercept is always the constant. It looks like (0, constant) when written in y-int form.

Answer:

slope (m) is 7/2 (aka 3.5) and y-int is (0,2)

Step-by-step explanation:

I don't really have an explanation, basically rearrange the problem so that to y is on the left but it would be 2y so divide the right side by two. I an explain further in depth if needed

Step-by-step explanation:

1 out of 13 would be equal to the amount of cards that would be a jack.

But you also have to take into regards the coin flip 50%chance so you would just could what the number is divided by to get the right answer. Since out come could be tails or head instead of just being one for sure for example.
