Answer:
y=5x+5
Step-by-step explanation:
What you're doing is creating an equation for #1 in slope-intercept form (y=mx+b)
Where m is the slope and b is your y-intercept!
If you already have 5 gallons in the tank and your adding 5 more gallons every minute, let x be your minutes:
For #2 you're going to graph this, but you need to know your slope and y-intercept! In this case your slope is 5 and your y-intercept is 5. your graph would look like the picture attached.
For #3, yes! It does make sense to draw a line because the amount of water is increasing in the tank by 5 gallons every minute, meaning it will increase until she stops it.
For #4 If there had been no water in the tank already then the whole equation would change to just being 
, because there would be no starting amount. This also means that the graph would look different and it would start at 0 rather than at 5.
The coordinates system is used to map out and locate objects throughout space. In navigation, satellites use GPS signals to determine where you are relative to a grid placed on earth. This grid typically follows longitudinal and latitudinal lines. Space uses this system in a similar way. Engineers and astronomers use grids to determine the location of planets, stars, and other celestial bodies in the universe. Finally, archaeology uses grids to help map out a site that is being dug. As artifacts are recovered, archaeologists record their location on a coordinate grid because it helps them interpret the living conditions or other human behaviors on the site.
Answer:
x^4 -2x^2 -24
Step-by-step explanation:
(x^2+4)(x^2−6)
FOIL
First: x^2*x^2 = x^4
Outer: x^2 *-6 = -6x^2
Inner: x^2 *4 = 4x^2
Last: 4*-6 = -24
Add them together
x^4 -6x^2 +4x^2 -24
Combine like terms
x^4 -2x^2 -24
This is in standard form since the powers decrease
Answer:
B
Step-by-step explanation:
It would be -100 because you would be withdrawing, not adding the amount, or staying with the same amount.
10 millions place. This is basic place value.
