8x > = -64
x > = -64/8
x > = -8
10x < 60
x < 60/10
x < 6
-8 < = x < 6
Answer:
the answer is 32%
Step-by-step explanation:
An equation whose roots are x=3 and x=11 is
|(x-3)(x-11)|=0
We can check that, plugging in x=3 or x=11, makes both sides of the equation equal.
Yes, it is a function as for every x value there is only one y value, you could also see that it is not a function by doing the vertical line test, this equation passes it.
You can just substitute the names for the numers: (all sugar was 3.5+0.75=4.25)
<span>a. granulated to brown sugar?
3.5:0.75
b. flour to brown sugar?
4.5:0.75
c. flour to all sugar?
4.5:4.25
but this looks ugly, so we can simplyfy it. Now, we can mupltiply all numbers by 100! (this will get rid of the .)
</span>
<span><span>a. granulated to brown sugar?
350:75
b. flour to brown sugar?
450:75
c. flour to all sugar?
450:425</span>
and they all are mupliples of 25, so let's divide all by 25!
</span>
<span>a. granulated to brown sugar?
14:3
b. flour to brown sugar?
18:3
c. flour to all sugar?
18:17
now they all look good, but the second one can still be simplified:
</span>
<span>a. granulated to brown sugar?
14:3
b. flour to brown sugar?
6:1
c. flour to all sugar?
18:17
that's the answer!
