The formula of a distance between A and B = |B - A|.
We have -3 and 4. Substitute:
|4 - (-3)| = |4 + 3| = |7| = 7
<h3>Answer: d) 7</h3>
Answer:
The answer to your question is the second choice (y ≥ 1/3x - 1)
Step-by-step explanation:
Process
1.- Find two points of the graph
A (0, -1)
B (3, 0)
2.- Find the slope
m = (0 + 1)/(3 - 0)
m = 1/3
3.- Find the equation of the line
y - y1 = m(x - x1)
y + 1 = 1/3(x - 0)
y + 1 = 1/3x
y = 1/3x - 1
4.- Find the equation of the inequality
We need the upper part of the line so the inequality must be
y ≥ 1/3x - 1
The simplest form of 18/45 is 2/5
We have y=2x and y=x+2
They both equal y, so substitute the first equation for y in the second equation.
2x=x+2
Let’s get x to one side. Let’s subtract x from both sides.
X=2
Since x=2, just plug in 2 for x.
2+2=4
So,
X=2
Y=4
Answer:
x=-1
Step-by-step explanation:
3x+7=7x+8-3x
3x+7=4x+8
-4x -4x
-x+7=8
-7 -7
<u>-x=1</u>
-1
x=-1
