3x^2 - 8 = 67
Solve for X

Answer:

−8x^4 + 5x^3 + x^2

Step-by-step explanation:

3x^3  + x^2  + 2 (x^3  − 4x^4)

Apply the distributive property.

3x^3  + x^2  + 2x^3  + 2 (−4x^4)

Multiply −4 by 2.

3x^3 + x^2 + 2x^3 − 8x^4

Simplify by adding terms.

Add 3x^3 and 2x^3.

5x^3 + x^2 − 8x^4

Simplify the expression.

Move x2.

5x^3 − 8x^4 + x^2

Reorder 5x^3 and −8x^4.

−8x^4 + 5x^3 + x^2

Graph (C) shows the equation of line y = 2x -1/2.

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

The given equation of line is,

y = 2x - 1/2         (1)

Standard equation of the line is y = mx + c

By comparison, slope of the line (1),

m = 2

To plot graph, find x and y intercept,

x intercept of line at y = 0,

0 = 2x - 1/2

2x = 1/2

x = 4

y intercept of line at x =0,

y = -1/2

The graph of the line is represented here.

Correct answer is option (3).

Answer:

C 40

Step-by-step explanation:

Using proportions, it is found that the horizontal distance, in feet, between the ends of the ramp is:

c 40

The rule of three is:

5 feet V - 100 feet H

2 feet V - x feet H

Applying cross multiplication:

[tex]5x = 200[/tex]

[tex]x = \frac{200}{5}[/tex]

[tex]x = 40[/tex]

Hence, 40 feet, option c.

Answer: The expression for the retail price of a silver chain is 1.4c.

Step-by-step explanation:

Let the amount of jewelry be c dollars.

Rate of mark up = 40%

So, Amount of mark up would be

[tex]\frac{40}{100}[/tex] times c

= 0.4c

So, Amount after mark up would be

c+0.4c

=1.4c

Answer: The expression for the retail price of a silver chain is 1.4c.

Answer:x=4

Step-by-step explanation:

You can split this up into two equations

x-4=0

x+5=0

To solve each:

x-4=0

Add 4 to each side

x=4

------------

x+5=0

Subtract 5 from each side

x=-5

So your two solutions are -5 and 4 but you want the positive one so the answer is x=4

Answer:

x = 25

Step-by-step explanation:

From the given picture,

In ΔMLN,

m∠NML + m∠MLN + ∠LNM = 180°

61° + 39° + m∠LNM = 180°

100° + m∠LNM = 180°

m∠LNM = 180° - 100°

m∠LNM = 80°

If JK║MN and JN is a transverse intersecting these parallel lines at N and J,

∠LNM ≅ ∠LJK [Alternate interior angles]

(3x + 5)° = 80°

3x = 80 - 5

3x = 75

x = 25

Answer:

The multiplier is 0.85

The depreciation equation is;

P = I(0.85)^t

Step-by-step explanation:

Let us write an equation for the depreciation

It is in the form;

P = I( 1 - r)^t

where P is the present value

I is the value at which it was bought

r is the depreciation percentage = 15% = 15/100 = 0.15

t is the number of years after byte year it was bought

so we can have;

P = 1000(1 - 0.15)^t

P = 1000(0.85)^t

The

multiplier is 0.85

Answer:

15

the answer is 15
