A Power is a short way to represent repeated multiplication. The power includes a base and an exponent. The base is the number that is multiplied. The exponent is the number of times the base is multiplied.


 <span>Note: The power of a negative base is positive if the exponent is even, and negative if the exponent is odd.</span><span>  </span><span> </span>


7(4)^2 + 3  substitute \ 4 \ for \ x

Ok guys i have only 1 hr to get this. Determine the y-intercept for the equation 3x + 2y = 12. HELP
sukhopar [10]

Answer:

x= -2/3 y+4

Step-by-step explanation:

Let's solve for x.

3x+2y=12

Step 1: Add -2y to both sides.

3x+2y+−2y=12+−2y

3x=−2y+12

Step 2: Divide both sides by 3.

3x

3

=

Answer:

y = 120x

Step-by-step explanation:

y=mx + b is what we need where m is the slope and b is the y-intercept.

the train travels at about 120km/hour, thus the slope is 120.

y= 120x +b. to find the y intercept plug in any coordinate.

240 = 120(2) +b. you find that the y-intercept is 0.

final equation: y= 120x
