Shes is wrong because 30% of 80 is 24
X= <span>√(54-3x)
square both sides:
x^2=54-3x
bring everything to the left:
x^2 + 3x - 54= 0
solve using quadratic formula:
x= (-3 +/- </span>√(9- 4(-54)))/2=
(-3+/- <span>√(9+216))/2=
(-3 +/- </span><span>√225/2=
(-3 +/- 15)/2=
two options:
1) x= (-3+15)/2= 12/2=6
2) x= (-3-13)/2= -18/2= -9</span>
Answer:
B
Step-by-step explanation:
In slope intercept form, y = mx + b, the m is the slope, the b is the y intercept, and x and y can be subbed in from the point you are given of (1, 3). We are told the slope, so everything we have fills in like this:
Now we just need to solve for b:
and
so
Answer:
Noah
Step-by-step explanation:
For Andre you would divide 208 words by 4 minutes getting 52 words per minute. Then, for Noah divide 342 words by 6 minutes getting 57 words per minute. Noah types faster because he can type more words per minute.
