Answer:
x = 3.8
y = 15.2
Step-by-step explanation:
y = 4x
y = 19 - x,
if y = y then,
4x = 19 - x
5x = 19
x = 19/5 = 3.8 now inputting the answer to x into one of the unchanged equations above (y = 4x),
y = 4x = 4*3.8 = 15.2
Double check:
y = 19 - x = 19 - 3.8 = 15.2
Answer:
There are 3 green marbles in the box.
Step-by-step explanation:
15% = 0.15
To figure out how much 15% of 21 is, you must multipl the decimal form of the percentage by the whole number. This will give you how much of that number that percentage is.
0.15 * 21 = 3.15
But you can't have 0.15 of a marble, so you must round as well.

Step-by-step explanation:
both multiply up to 24
"T<u>he function is decreasing":</u>
This means the slope of the function will be negative at the given point. Anywhere the line is going down, from left to right, is decreasing. This eliminates choices A and C.
<u>"The function is concave down":</u>
This means the curve of the function will be open down (think of an upside down u). This eliminates choice E.
<u>"f(x)>0":</u>
This is anywhere the curve is above the x axis. This eliminates choice D.
The answer is Choice B) x=2.
Hope this helps!!
