Answer:

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Answer:

The domain represents the possible inputs of a function.

Step-by-step explanation:

The domain of a function is all of the possible x values that it can include.

These x values can also be called inputs of the function.

The x values are the inputs, and the y values are the outputs, in a function in the form of f(x) =

So, the statement best describing the domain of a function is The domain represents the possible inputs of a function.

Answer:

C) The y-intercept will always be the vertex.

Step-by-step explanation:

We have the quadratic function in the form:

[tex]f(x)=ax^2+bx+c[/tex]

And we want to determine the true statement when b = 0.

Let's go through each of the choices and examine its validity.

Choice A)

Recall that according to the quadratic formula, the roots of a function is given by:

[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

If b = 0, then we acquire:

[tex]\displaystyle x=\frac{-(0)\pm\sqrt{(0)^2-4ac}}{2a}=\pm\frac{\sqrt{-4ac}}{2a}[/tex]

As we can see, as long as the inside of the square root is positive, the graph will have x-intercepts. So, b equalling zero does not guarantee that the graph does not have any x-intercepts.

A is false.

Choice B)

A quadratic has a minimum if it curves upwards and a maximum if it curves downwards.

This is decided by the leading coefficient a. b does not affect whether a quadratic curves downwards or upwards.

B is false.

Choice C)

The vertex of a quadratic is given by:

[tex]\displaystyle \text{Vertex}=\left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]

If b = 0, then the x-coordinate of the vertex is given by:

[tex]\displaystyle x=-\frac{(0)}{2a}=0[/tex]

Then the y-coordinate will be:

[tex]f(0)=a(0)^2+b(0)+c=c[/tex]

So, the vertex is (0, c).

This is also the y-intercept as, by definition, the y-intercept is the value when x = 0.

So, Choice C is the correct choice.

Choice D)

The axis of symmetry is the x-coordinate of the vertex. As we saw earlier, the x-coordinate of the vertex will always be:

[tex]\displaystyle x=-\frac{(0)}{2(a)}=0[/tex]

Zero is neither positive nor negative. Thus, D is false.

Answer:

The y-intercept will always be the vertex.

Since the denominators are unequal, we find the L.C.M (lowest common multiple) for both denominators.

The L. C. M for 7 and 8 is 56.

Now,

➺[tex] \: \frac{ - 3 \times 8}{7 \times 8} + \frac{7 \times 7}{8 \times 7} [/tex]

Now that the denominators are equal, we can add them.

Answer:

x=2

Step-by-step explanation:

15x-10=20

+10 to both sides

15x=30

divide both sides by 15

x=2

Answer:

x = 2

Step-by-step explanation:

15 x - 10 = 20

15 times 2 = 30

30 -10 = 20

20 = 20

So x equals 2

Answer:

3x-8

Step-by-step explanation:

9x²-64  is the same as

(3x)² - 8²

now we have the difference of 2 squares, a²-b² =(a -b)(a +b), where a=3x, b=8

9x²-64 =  (3x-8)(3x+8)

2x - 4 = 1

2x = 1 + 4

2x = 5

x = 5/2

Answer:

x=2

Step-by-step explanation:

the minimum value of y is when x = 2.

Answer:

The minimum is at x = -2

Step-by-step explanation:

f(x) = (x+2)^2 -3

This is in vertex form

f(x) = ( x-h)^2 +k  where (h,k) is the vertex

Since this is an  upwards  opening  parabola the vertex is the minimum

f(x) = (x- -2)^2 -3

The vertex is (-2,-3)

The minimum is at x = -2

Answer:

y=8x-26

y=-1/8x-13/8

Step-by-step explanation:

Y=kx+b

When the two lines are parallel,

k1=k2

k2=8 And passes through the point (3, -2)

So y+2=8(x-3)

Get the answer y=8x-26

When the two lines are perpendicular,

k1*k2=-1

K2=-1/8 And passes through the point (3,-2)

So y+2=-1/8（x-3）

Get the answer y=-1/8x-13/8

Step-by-step explanation:

To Find :

The area of green shaded region in given image.

Solution :

The area of green shaded region is given by :

Area = Area of outer square - Area of inner rectangle

Area = x² - ( x - 20)×( x - 25 )

Area = x² - ( x² - 25x - 20x + 500 )

Area = 45x - 500

Hence, this is the required solution.
