Answer:
(2,5)
Step-by-step explanation:
(X<em>m</em>, Y<em>m</em>)= ( (x1+x2)/2, (y1+y2)/2 )
= (5 + (-1))/ 2, (5+5)/2
= (4)/2, (10)/2
= 2, 5
Answer:
1 no
2 I don't know
3 no
4 yes
5 2.5 is the slope
6 -0.5
7 no slope
Step-by-step explanation:
1 no because the y overlaps
2 not sure
3 it over laps
4 it never overlaps
5 y=2.5x-3
6 y=-0.5x+1
7 no slope it's just x=-2
for the 5-7 you can type that into demos and get more info
y=mx+b
m is the slope and b is y intercept
Given that Nicholas has a 115 fantasy and science fiction books which is 46% of his collection.
Now we have to find what is total number of books in his collection.
Let number of books in Nicholas collection = x
then number of fantasy and science fiction books = 46% of x = 0.46x
We already know that he has 115 fantasy and science fiction books, so both values will be equal and give equation:
0.46x=115
now we can solve this equation to find the answer.
x= 250
Hence final answer is:
Nicholas has 250 books in his collection.
Answer:
-4/3x + -28/3
Step-by-step explanation:
First you rearrange 4y-3x=1
y= 3/4x +1/4
then you reciprocate and change the sign the slope since you are trying to find a line perpendicular to it.
Slope(m) =-4/3
then you use the formula <em>y-y1= m(x-x1)</em>
y-0= -4/3 (x--7)
y= -4/3 +-28/3
