 first one ( 3, 7, 11, 15) because it is going by 4

Linear means that the y values go up in a fixed increment, k.
In the first one, you see that 3+4=7, 7+4=11, and so on, so you can immediately tell that it's linear.

The second one goes 3+5=8, then 8+7=15, then 15+6=21, which aren't the same numbers.

The third increases and decreases, so it's not linear.

The fourth goes 3+6=9, then 9+18=27, which you can immediately tell is not linear.

Therefore, the only linear table would be the first one.

gregori [183]

Answer:

Step-by-step explanation:

12X-20=5-3X

12X+3X=5+20

16X=25

Which statement best explains whether the table represents a linear or nonlinear function?
Marta_Voda [28]

Answer: A.) It is a linear function because there is a constant rate of change in both the input and output values.

============================================================

Explanation:

Note how x is decreasing by 3 each time

  • -2-3 = -5
  • -5-3 = -8
  • -8-3 = -11

At the same time, y is also decreasing by 3 each time

  • 7-3 = 4
  • 4-3 = 1
  • 1-3 = -2

This means we have a linear function. We have,

slope = (change in y)/(change in x)

slope = (-3)/(-3)

slope = 1

Recall that slope is another term for rate of change, so a constant slope means we have a constant rate of change.

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

Another way to find the slope is to pick any two points from the table and use the slope formula

m = (y2 - y1)/(x2 - x1)

You should find that any two points you pick will lead to a slope of 1. I recommend you try out all possible pairs to help convince yourself the slope is 1.

Find the Domain: Show all steps <br><br> h(x)=2(x+5)^2-5
kobusy [5.1K]

Answer:

The domain is all real numbers (see the explanation)

Step-by-step explanation:

we have

h(x)=2(x+5)^2-5

This is a vertical parabola open upward (the leading coefficient is positive)

The vertex represent a minimum

The vertex is the point (-5,-5)

we know that

The domain of a function is the set of all possible values of x

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

In this problem

The domain is the interval (-∞,∞)

The domain is all real numbers

The range is the interval [-5,∞)

All real numbers greater than or equal to -5

Solve for x 5(x+1)=4(x+8)
joja [24]

Answer:

x=27

Step-by-step explanation:

expanding the above expression we get

5x+5=4x+32

grouping numbers with coefficient of x at the left side and constant at the right side we get

5x-4x=32-5

x=27
