Are the associative properties true for all integers
Ymorist [56]
Associative property works in addition and multiplication.
Associative property in Addition: (a + b)+ c = a + (b + c)
Associative property in Multiplication: (a x b) x c = a x (b x c)
Associative property in Subtraction: (a - b) - c is not equal to a - (b - c)
Associative property in Division: (a divided by b) divided by c is not equal to a divided by (b divided by c).
Thus, associative property is not true for all integers.

PLSS HELPP BRAINLIEST AND 65 POINTS <br> pls do the graph too
Eddi Din [679]

Answer:

\Large \boxed{ -x+65}

Step-by-step explanation:

Two points are (0, 65) and (10, 55)

Calculate slope <em>m</em>

\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}

\displaystyle m=\frac{55-65}{10-0}=-1

Use slope-intercept form

y=mx+b

y=-1x+b

<em>b</em>  is the y-intercept, y-intercept is (0,65)

y=-1x+65

Answer: V=60

Explanation-
The first step is to find the resistance in the current with 480 volts.
The equation for resistance is= voltage/current(amps)
So the equation would be: 480/12
Solve: 480/12=40 ohms
40 is the resistance
Now you will use this the answer the seconds part.
In the second part you are finding the voltage.
Equation for voltage: V= current x resistance
So the equation would be: 1.5 amps x 40 ohms
Solve: 1.5 x 40= 60 volts
