Answer:
69
Step-by-step explanation:
Add the two equations together
2x+5y+6x-5y=17-9
Combine like terms
8x=8
Divide
x=1
Plug the x value in
2(1)+5y=17
2+5y=17
5y=15
y=3
Final answer: (1,3)
Answer:
- second kick goes farther
- first kick goes higher
Step-by-step explanation:
Assuming the kick started from ground level, the path of the ball is assumed to be symmetrical about the high point. That is, the first kick will land 2×20 = 40 yards downfield.
The equation for the second kick can be rewritten as ...
y = 0.008x(50 -x)
The value of y will be zero at x=0 and at x=50. The second kick will land 50 yards downfield, a greater distance than the first kick.
At x=25, the height of the second kick is ...
y = 0.008(25)(50-25) = 5 . . . yards
The second kick travels farther (50 yds vs. 40 yds).
The first kick travels higher (8 yds vs. 5 yds).
Answer:
If you are to express 5000 in scientific notation form, it would be:
5 ·
Step-by-step explanation:
Looking at it, there is only 1 sig fig (significant figure) and this means if you are to change it to number from between 1 - 10
it would be: 5
so it would look like 5.000 or just 5.
5,000. vs. 5.000 are both completely different things, that are expressed in different ways. But in this case, you can see that we have move the decimal place 3 times, which is why we have
That is how you get your answer!
<span>Starting with x−24/x<10 multiply everything by x.
x^2-24<10x
Subtract 10x from both sides.
x^2-10x-24 < 0
Factor.
(x-12)(x+2) < 0
(x+2) is always positive since x > 0, but (x-12) is negative when x is a value between 0 and 12. This negative value for (x-12) satisfies that the left side is less than 0. Thus the solution set for x is (0,12).</span>
