y= -2x+3
Step-by-step explanation:
y= 2x-1 is wrong
First, we will start by identifying the y-int, the y-int is when x is zero. The y-int is 3 since when x is 0, y is 3, (0,3).
y= 2x+3 (So that means -1 is actually 3)
Plus even if your slope is 2, since from the 2 points you go up 2 and run by 1, if you're not going to calculate it with 2 points, you need to see if its uphill, downhill, etc. (More info in the image below) The slope is actually negative meaning it is -2.
So the equation of the line is actually y= -2x+3
Answer:
factor and get 4 ( 3x + 2y )
Step-by-step explanation:
4 x 3 is 12 and 4 x 2 is 8
We are given
(x) = –4x and g(x) = 5x²
The composition of f with g should be done this way:
<span>[f o g](x) = f [ g(x) ]
= f ( 5x</span>² )
= -4 (5x²)
- 20 x²<span />
Answer:
x = 0.3
Step-by-step explanation:
AM + MN = AN
But AN = 5
Therefore it does not matter where M is
7x + 0.1 + 10x - 0.2 = 5 combine like terms on the left
7x + 10x + 0.1 - 0.2 = 5
17x - 0.1 = 5 Add 0.1 to both sides.
17x - 0.1+0.1=5+0.1
17x = 5.1 Divide by 17
17x/17 = 5.1/17
x = 0.3 Answer
