Answer:

This quadratic equation has 2 solutions.

Step-by-step explanation:

I assume the '?' in your question is meant to be power 2 (²), or else it would not be a quadratic equation. You could write it using the superscript version of 2.

We can solve this equation by expressing it in the form: ax² + bx + c

x² + 9x= -8

x² + 9x + 8 = 0

Now if you know the discriminant, you can simply plug in your values of a, b, and c to see how many solutions there are.

In this case, you would not need the discriminant as there are whole-number factors and hence this can simply be factorised.

x² + 9x + 8 = 0

(x + 8)(x + 1) = 0

For this equation to be true (= 0), x can equal -8 OR -1.

Hence, this quadratic equation has 2 solutions.

Answer:

Oh, it's y=3x-4.

Because it's slope is 3 and it crosses through -4 on the y axis, we know that that would be the equation.

Good luck with the assignment man, let me know of anymore questions. :)

Answer:

6

Step-by-step explanation:

2x + 3y = 18 can be simplified into an y = mx + b equation, where b is the y intercept.

First, subtract 2x from both sides to get 3y alone.

3y = 18 - 2x

Then, divide both side by 3 to get y completely alone.

y = 6 - 2x

Rearrange the equation to be in the form of y = mx + b;

y = -2/3x + 6

6 is our Y intercept.

You can also use a graphing calculator if you want to check your answer, desmos is a great graphing calculator you can use.

Answer:

Step-by-step explanation:

Area = base * height

Area = (10 s) * (5 m/s)

Area = 50 m Area = 0.5 * base * height

Area = 0.5 * (5 s) * (10 m/s)

Area = 25 m

Answer:

1. -5a

Step-by-step explanation:

The definition of combining like terms is adding their coefficients, for example: 2x + 3x = (2+3)x = 5x.

So for this one, -21a+16a = (-21+16)a = -5a.

Answer:

[tex]\iint_D 8y^2 \ dA = \dfrac{88}{3}[/tex]

Step-by-step explanation:

The equation of the line through the point [tex](x_o,y_o)[/tex] & [tex](x_1,y_1)[/tex] can be represented by:

[tex]y-y_o = m(x - x_o)[/tex]

Making m the subject;

[tex]m = \dfrac{y_1 - y_0}{x_1-x_0}[/tex]

∴

we need to carry out the equation of the line through (0,1) and (1,2)

i.e

y - 1 = m(x - 0)

y - 1 = mx

where;

[tex]m= \dfrac{2-1}{1-0}[/tex]

m = 1

Thus;

y - 1 = (1)x

y - 1 = x ---- (1)

The equation of the line through (1,2) & (4,1) is:

y -2 = m (x - 1)

where;

[tex]m = \dfrac{1-2}{4-1}[/tex]

[tex]m = \dfrac{-1}{3}[/tex]

∴

[tex]y-2 = -\dfrac{1}{3}(x-1)[/tex]

-3(y-2) = x - 1

-3y + 6 = x - 1

x = -3y + 7

Thus: for equation of two lines

x = y - 1

x = -3y + 7

i.e.

y - 1 = -3y + 7

y + 3y = 1 + 7

4y = 8

y = 2

Now, y ranges from 1 → 2 & x ranges from y - 1 to -3y + 7

∴

[tex]\iint_D 8y^2 \ dA = \int^2_1 \int ^{-3y+7}_{y-1} \ 8y^2 \ dxdy[/tex]

[tex]\iint_D 8y^2 \ dA =8 \int^2_1 \int ^{-3y+7}_{y-1} \ y^2 \ dxdy[/tex]

[tex]\iint_D 8y^2 \ dA =8 \bigg [ -16+\dfrac{64}{3} + 1- \dfrac{8}{3}\bigg][/tex]

[tex]\iint_D 8y^2 \ dA =8 \bigg [ -15+ \dfrac{64-8}{3}\bigg][/tex]

[tex]\iint_D 8y^2 \ dA =8 \bigg [ -15+ \dfrac{56}{3}\bigg][/tex]

[tex]\iint_D 8y^2 \ dA =8 \bigg [ \dfrac{-45+56}{3}\bigg][/tex]

[tex]\iint_D 8y^2 \ dA =8 \bigg [ \dfrac{11}{3}\bigg][/tex]

[tex]\iint_D 8y^2 \ dA = \dfrac{88}{3}[/tex]

Answer:

21.5625

Step-by-step explanation:

So You would divide 258.75 / 12 = 26.5625

The radius of container is 2.6 inch.

The amount of space occupied by a three dimensional figure as measured in cubic units.

[tex]volume of cylinder= \pi r^{2} h[/tex]

where,

r is the radius

h is the height

According to the given question

shape of the container is cylindrical.

Height of the container, h = 12 inches

Volume of container = 258.75 cubic inches

for the radius of the container

volume of container = [tex]\pi r^{2}h[/tex]

258.75 = 3.14×[tex]r^{2}[/tex]×12

258.75 =37.68×[tex]r^{2}[/tex]

[tex]\frac{258.75}{37.68} =r^{2}[/tex]

[tex]6.9=r^{2}[/tex]

⇒ [tex]r = \sqrt{6.9} =2.62inch[/tex] = 2.6 inch

Hence, the radius of container is 2.6 inch.

Step-by-step explanation:

Sales price = $35

25% rush charge = 35 * 25% = $8.75

Rush charge is taxable = (35 + 8.75) * 8% = $3.5

Total purchase price per unit = 35 + 8.75 + 3.5 = $47.25

Total cost = Total Purchase + Shipping

Answer:

165.34 pounds OR 165 lb

Step-by-step explanation:

Given:

A triangle with vertices A(0,0), B(6,0), and C(0,9) is rotated 360 about the y-axis.

To find:

The volume of the figure.

Solution:

Points A(0,0) and C(0,9) lies on the y-axis. Length of AC is 9 units.

Points A(0,0) and B(6,0) lies on the x-axis. Length of AB is 6 units.

If a triangle with vertices A(0,0), B(6,0), and C(0,9) is rotated 360 about the y-axis, then it will form a cone with radius 6 units and height 9 units.

Volume of a cone is

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

where, r is radius of the base and h is vertical height of the cone.

Putting r=6 and h=9, we get

[tex]V=\dfrac{1}{3}\pi (6)^2(9)[/tex]

[tex]V=\pi (36)(3)[/tex]

[tex]V=108\pi[/tex]

Therefore, the volume of the figure is [tex]108\pi[/tex] sq. units.

20 Mystery DVD’s

Step-by-step explanation:

32/8=4

4*5=20

Answer:

There are 20 Mystery DVD's.

Step-by-step explanation:

Since the ratio of Drama to Mystery is 8:5, then we can conclude that 32:x is another equivalent form of the ratio, given that 32 represents drama, and x represents the unknown number of mystery.  

Set up the ratios as 8/5 as one fraction, and 32/x as another, but make them equal each other.  Cross multiply the numerators and denominators, then you will get 8x=160

divide both sides to solve for x.

x=20

The unit price of 12 gallons of gasoline that costs $39.48 is $3.29 per gallon

The given parameters are:

Gallons = 12

Cost = $39.48

The unit price is calculated as:

Unit = Cost/Gallon

So, we have:

Unit = $39.48/12

Divide

Unit = $3.29

Hence, the unit price of 12 gallons of gasoline that costs $39.48 is $3.29 per gallon
