Answer:
5+d2
Step-by-step explanation:
We'll make d=day
5+d2
5 is the base price
and 2 is the number that increases by day
Please tell me if it's incorrect
Happy Holidays!
The solution would be like
this for this specific problem:
Since he’d leave the science assignments for
the next day, you just need to remove the y in the equation because y
represents the number of science assignments.
<span>The equation 2x + y = 8 will be
converted to 2x = 8.</span>
2(4) = 8
<span>If he has 8 hours to complete a set of
assignments, then he can complete 4 math assignments if he decides to leave
the science assignments for the next day. </span>
The correct answer between all
the choices given is the last choice or letter D. I am hoping that this answer
has satisfied your query and it will be able to help you in your endeavor, and
if you would like, feel free to ask another question.
Hello,
I)
1 solution with multiplicity 2
(2x+1)²=0
II) ANSWER C (-4.41, -1.59)
-3-√2 and -3+√2
III)
y=x²+2x
y=3x+20
==>x²+2x=3x+20
==>x²-x-20=
Δ=1+4*20=81=9²
(x=(1-9)/2=-4 and y= 3*(-4)+20=8 ) or (x=(1+9)/2=5 and y=3*5+20=35)
You divide the problem on both sides of the equation. Example would be 3x=9x . divide that by 3 and you get "x=3x"
Answer:
20 feet
Step-by-step explanation:
Since the term -(x-7)^2 is negative, the largest height that the ball can reach is when this term is 0. 0+20=20, meaning that the highest the ball can go is 20 feet. Hope this helps!
