18,54,162,... what is the 8th term.

Answer:

C. x=-2

Step-by-step explanation:

To solve use PEMDAS,

First, distribute

6-x=20+4x-4

Then, combine like terms

6-x=16+4x

Add x to both sides

6=16+5x

Subtract 16 from both sides

-10=5x

Divide both sides by 5

-2=x

The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 147 days. Then the correct option is A.

The quadratic equation is given as ax² + bx + c = y. Then the degree of the equation will be 2.

The table shows the connection between the width in kilometers of an oil slick and the time in days. A capability can be utilized to show this relationship.

The equation at (2.4, 1) will be given as,

2.4 = a (1)² + b (1) + c

2.4 = a + b + c                 ...1

The equation at (9.4, 2) will be given as,

9.4= a (2)² + b (2) + c

9.4 = 4a + 2b + c                 ...2

The equation at (21.1, 3) will be given as,

21.1 = a (3)² + b (3) + c

21.1 = 9a + 3b + c                 ...

Solve equations 1, 2, and 3 with the calculator, then we have

a = 2.35, b = -0.05, c = 0.1

Then the equation is given as,

y = 2.35x² - 0.05x + 0.1

The best prediction of the time required for the oil spill to reach a diameter of 10 km will be

y = 2.35(10)² - 0.05(10) + 0.1

y = 235 - 0.5 + 0.1

y = 235.5

The value of y is nearer to the value of 233. Then the value of y will be 233 days.

The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 233 days. Then the correct option is D.

Answer:

  y = -4x +9

Step-by-step explanation:

The same slope-intercept equation can be used, but with a different y-intercept. That new y-intercept can be found from the given point (x, y) using the formula ...

  b = y -mx

  b = 5 -(-4)(1) = 9

So, the equation with the new y-intercept is ...

  y = -4x +9

Answer:

y = -25x + 170

Step-by-step explanation:

For the graph equation y = ax + b, we have to find a and b.

Pick two points that are on the grid for best accuracy.

e.g., (2,120) and (6,20)

Then a = (20-120)/(6-2) = -25

b is the y coordinate of the line with the y axis: 170

So the formula is:

y = -25x + 170

The monthly rent during the 8th year of living in the apartment will be $2160.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

You rent an apartment that costs $800 per month during the first year, but the rent is set to go up by $170 per year.

Then the monthly rent during the 8th year of living in the apartment will be

Let y be the monthly rent and x be the number of years.

Then we have

y = 170x + 800

The rent after 8 years, then the rent will be

y = 170 × 8 + 800

y = 1360 + 800

y = $ 2160

Thus. the monthly rent during the 8th year of living in the apartment will be $ 2160.

I think that the correct answer is D 3(2x + 4) = 6x + 12

3(2x + 4) = 6x + 12 illustrates the Distributive Property. Correct option is D.

The Distributive Property states that when you multiply a number by a sum or difference inside parentheses, you distribute the multiplication across each term inside the parentheses.

The correct illustration of the Distributive Property among the given options is:

D. 3(2x + 4) = 6x + 12

This is because when you distribute 3 across 2x and 4, you get 6x for the first term (3 * 2x) and 12 for the second term (3 * 4), resulting in 6x + 12.

Step-by-step explanation:

Answer: y=-1/2x+58, decreases 500, begins, 58k

Step-by-step explanation:

I'm not too sure about my equation for the word problem but I can explain how I got it.

The equation is in y=mx+b format, so we need to find the slope. They gave us the graph for a reason. You would take each side of the table and subtract/add. For example: 58-53=-5 (y), 0+10=10 (x).

Then, just put that in rise over run (-5/10).

Simplify. Which gives you -1/2.

They already gave us the y-intercept, so just put it into the equation. y=-1/2x+58.

Keep in mind I don't know if you need to add the 0's because it's thousands of feet, I would just in case though. Hoped this helped!

The equation can be given as  [tex]y= -\frac{1}{2}x +58[/tex], and slope for x and y is m that is [tex]\dfrac{-1}{2}[/tex].

Given to us,

x is time in minutes

y is the height (in thousands of feet) of the UAV

x                      y

0                      58

10                    53

20                   48

30                   43

The equation can be given as y = mx+ c

where,

x is time in minutes,

y is the height,

m is the slope,

c is the constant,

Substituting the values of x and y to get m and c,

Equation 1:

[tex]y = mx+ c\\ 58 = m(0) + c \\ c = 58[/tex]

Substituting the values of c to get m,

Equation2:

[tex]y = mx+ c\\53 = m(10) + 58\\m\times (10) = - 58 + 53\\m\times (10) = -5\\m =- \frac{1}{2}[/tex]

[tex]y= -\frac{1}{2}x +58[/tex]

Therefore, the equation can be given as  [tex]y= -\frac{1}{2}x +58[/tex], and slope for x and y is m that is [tex]\dfrac{-1}{2}[/tex].
