Answer:

Third option.

Step-by-step explanation:

In the picture attached, the question is shown. There we can see that as x gets bigger (x → ∞), f(x) gets smaller (f(x) → -∞ ). On the other hand, as x gets smaller (x → -∞), f(x) gets bigger (f(x) → ∞ ).

Answer:

slope: -3

y-intercept: -5

equation: y = -3x - 5

Step-by-step explanation:

The formula for slope is:

(y2 - y1)/(x2 - x1)

Let's use these coordinates:

(-1, -2)

(0, -5)

x1 = -1

x2 = 0

y1 = -2

y2 = -5

Substitute into the formula:

(y2 - y1)/(x2 - x1)

(-5 + 2)/(0 + 1)

Solve:

(-5 + 2)/(0 + 1)

-3/1

= -3

slope = -3

The y-intercept is when the x coordinate is 0.

Looking at the table, we see the coordinate (0, -5).

The y-coordinate is -5.

This means that the y-intercept is -5

y-intercept = -5

Slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept

m = -3

b = -5

Substitute:

y = mx + b

y = -3x - 5

Step-by-step explanation:

A) Cost of canvas = $ x

Cost of  4 canvases = 4 *x = 4x

Money left over after buying 4 canvases = $2.20

Equation:  25 - 4x = 2.2

Solution:     Subtract 25 from both sides

                -4x = 2.2 - 25

               -4x = - 22.8

Divide both sides by (-4)

    -4x/-4 = -22.8/-4

              x =  5.7

B) Money in Molly's account= x

4 times of Molly's account  = 4x

Equation: 4x - 2.2 = 25

Solution:   4x = 25 +2.2

                  4x = 27.2

                    x = 27.2/4

                   x = 6.8

Answer:

Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].

Step-by-step explanation:

Diameter of cylinder, D = 6 feet

Relation between Radius, R and diameter, D is given by:

[tex]R = \dfrac{D}{2}[/tex]

So, radius, R = [tex]\frac{6}{2} \Rightarrow 3[/tex] feet

Let height of cylinder be [tex]h[/tex] feet.

Formula for volume of cylinder is given by:

[tex]V = \pi R^{2} H[/tex]

Where, R is the radius of base of cylinder

and H is the height of cylinder

We are given that,

[tex]V = \dfrac{36 \pi}{5} ft^{3}[/tex]

Using formula for volume, [tex]V = \pi R^{2} H[/tex]

[tex]\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft[/tex]

Hence, Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].

Answer:

x = -24/7

Step-by-step explanation:

To solve, you need to multiply both sides by 10 ( the GCF of 5 and 2) to get rid of the fractions. Once multiplied, you get this:

2(4x-2) + 5(1) = 5(3x+7) - 10(1)

Now, just distribute the parenthesis:

8x - 4 + 5 = 15x + 35 - 10

Now, combine like terms:

8x + 1 = 15x + 25

15x + 25 = 8x + 1 (rearranged the equation)

Subtract the x's:

7x + 25 = 1

Now solve:

7x = -24

x = -24/7

Answer:

(0, -2)

Step-by-step explanation:

A turning point is a point at which the derivative changes sign from positive to negative or vice versa. Then, a turning point coincides with a relative maximum or a relative minimum (also known as local minimum and maximum).

From the table, we see that f(x) decreases from x = -6 to x = 0 and it increases from x = 0 to x = 6. Therefore, there is a minimum at (0, -2)

Answer:

1.5

Step-by-step explanation:

Given the pair of points on the table.

Now the formula for slope, [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

To calculate the slope we only require two pair of points.

Let us take: [tex](x_1, y_1)=(-5,0)$ and (x_2, y_2)=(-3,3)[/tex]

[tex]m=\dfrac{3-0}{-3-(-5)}\\=\dfrac{3}{-3+5}\\=\dfrac{3}{2}\\m=1.5[/tex]

The slope of the linear function represented by the values in the table is 1.5.

Note: You can use any two set of values. The result will be the same.

Answer:

The equation of the line in slope-intercept form is:

[tex]y=-\frac{3}{7} x+3\\[/tex]

In one of the many possible standard forms:

[tex]3\,x+7\,y=21[/tex]

Step-by-step explanation:

First calculate the slope of the segment that joins these two points: (0, 3) and (7,0):

[tex]slope=\frac{y_2-y_1}{x_2-x_1}= \frac{0-3}{7-0}=-\frac{3}{7}[/tex]

Now, knowing that the y-intercept is (0, 3) [point on the y-axis (for x=0) where the line crosses], Then the equation of the line in slope-intercept form is:

[tex]y=m\,x+b\\y=-\frac{3}{7} x+3[/tex]

And now, if you want to write the equation eliminating fractions, we can multiply both sides by "7":

[tex]y=-\frac{3}{7} x+3\\7\,y=-3\,x+21\\3\,x+7\,y=21[/tex]

Answer:

I think it is N= 15.1

Answer: D

Step-by-step explanation:

If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.

x = 9y^2-12.

Then you solve for y.

x = 9y^2-12.

x+12=9y^2

y^2=(x+12)/9

y=sqrt((x+12)/9)

y=sqrt((x+12))/3 which is D

Answer:

Undefined

Step-by-step explanation:

To find the slope, you need the formula, y₂-y₁ divided by x₂-x₁.

That is 1-8 divided by -2-(-2), or -7 divided by 0.

Anything divided by 0 is undefined, so the answer is undefined.

Quadratic Equations! Yes!

Step-by-step explanation:

Now, there are three methods to solving this:

1.Quadratic Formula

2.Factoring

3. Completing the square

Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.

So, Quadratic Formula! To solve it using this method, we have to find x using this: [tex]x=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex](the +- before the square root means it could be both positive or negative)

Where a, b are coefficients and c is a term(in a quadratic equation form: [tex]ax^{2} +bx+c=0[/tex])

So, we just have to input the stuff from our equation into the formula!

[tex]x=\frac{-4+-\sqrt{32} }{2}[/tex]

Now, we can simplify the square root of 32 into 4 times the square root of 2

[tex]x=\frac{-4+-4\sqrt{2} }{2}[/tex]

And, we can divide 2 from it all!

[tex]x=-2+-2\sqrt{2}[/tex]

So, there you have it! The Answer is C, or 3.

Hope this helps!
