Absolute value- the
real number without regard to its sign.

Multiplication- *Negative* x *Negative* = Positive alwayss

Multiplication- *positive* + * Negative* = Negative always (same vise versa)

Division- *Negative* x *Negative* = Positive alwayss

Division - *positive* + * Negative* = Negative always ( same vise versa )

Additon- You do keep change change with this one ( example- -7 + 6 change this too- (-7 - (-6) = -1)
no matter weather its a positive or negative number KEEP THE SIGN OF THE BIGGER NUMBER!

Subtraction- You do keep change change with this one also ( example- 6 - -12 change this too- (6 + (12) = -18)
no matter weather its a positive or negative number KEEP THE SIGN OF THE BIGGER NUMBER!

Hope this helped

timurjin [86]

Answer:

  • $10 per hour
  • 0.1 hours

Step-by-step explanation:

To find Carys' earnings in one hour, fill in h=1 in the formula:

  E = 10·1 = 10

Carys earns 10 dollars per hour.

__

To find the number of hours required to earn 1 dollar, fill in E=1 in the formula:

  1 = 10h

  0.1 = h . . . . . divide by 10

It takes 0.1 hours for Carys to earn 1 dollar.

A certain insect can beat its wings 120 times per second write an equation in slope intercept from that shows the relationship b
dalvyx [7]

Answer:

The relationship between flying time in seconds in the number of times the insect beats its wings:

  • y = 120x

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the rate of change or slope
  • b is the y-intercept

In our case,

Let 'x' be the flying time in seconds

Ley 'y' be the number of times the insect beats its wings

Given that a certain insect can beat its wings 120 times per second.

It indicates that the rate of change or slope = m = 120

In our case the y-intercept b = 0, as there is no initial condition mentioned here.

Now, substituting m = 120 and b = 0 in the slope-intercept form

y = mx+b

y = 120x+0

y = 120x

Therefore, the relationship between flying time in seconds in the number of times the insect beats its wings:

  • y = 120x
