Answer: 31 nickels and 29 dimes
<u>Step-by-step explanation:</u>
Nickels (.05): x
Dimes (.10): y
Value: .05x + .10y = 4.45 → -20(.05x + .10y = 4.45) → -x - 2y = -89
Quantity: x + y = 60 → 1(x + y = 60) → <u> x + y </u> = <u> 60 </u>
-y = -29
y = 29
Next, substitute "29" for "y" into either equation and solve for "x":
x + y = 60
x + 29 = 60
x = 31
Answer:
It's point W!!!
Step-by-step explanation:
Have a great day :)
Acceleration is simplified by assuming it is the constant -g
a=-g we integrate this with respect to time to get v...
v=-gt+C where C is the initial velocity in this case 14ft/s so
v=-gt+14 integrate again to get the height function
h=(-gt^2)/2 +14t +C we are not given an initial height so C is 0
h(t)=14t-gt^2/2 letting g=32 and neatening up a bit...
h(t)=14t-16t^2

Answer: x-4</h3>
We simply drop the absolute value signs and write whatever is inside
This is because |x-4| is really composed of two equations and it depends on what x is
If x < 4, then we use -(x-4) or -x+4
If x >= 4, then we use x-4
This is from the idea that |x| breaks down into this piecewise function
Replace every x with x-4
Then for each inequality, you would solve for x to get the following
which is the same as
Answer:
all the values
Step-by-step explanation:
so all the values for x are solutions
