Answer:
the equation of the perpendicular bisector of segment AB is y = -2x + 7
Step-by-step explanation:
Going from B(-1, 4) to A(3, 6), x increases by 4 and y increases by 2. Thus, the slope of this line is m = rise / run = 2/4, or 1/2.
Any line perpendicular to the one joining A and B has a slope which is the negative reciprocal of 1/2: that'd be -2.
3 - 1 6 + 4
The midpoint of line segment AB is ( --------- , ---------- ), or (1, 5)
2 2
Thus, the perpendicular bisector passes through the midpoint (1, 5) and has slope -2:
Starting from y = mx + b, we get 5 = -2(1) + b, or 7 = b, and so the equation of the perpendicular bisector of segment AB is
y = -2x + 7
The y- intercept of this equation is 4/1=4.00000
Explanation: y tells us how far up the line goes Notice that when x = 0 the value of y is 4/1 so this line "cuts" the y axis at y= 4.00000
<h2>
Answer:</h2><h2>The chance is 100 % since we have not seen it in the past three days.</h2>
Step-by-step explanation:
The odds of seeing a black cat are 25% every day.
It also means that the possibility of seeing a black cat is once in 4 days, since 25%
Given, we have not seen one black cat in 3 days.
The chance of seeing a black cat on the 4th day = ?
= 100 % since we have not seen it in the past three days.
Answer:
Step-by-step explanation:
1)x/4.1=-2
2)multiplyby 4.1 on both sides x/4.1*4.1=-2*4.1
3) x=-8.2
