Answer:
6
Explanation:
According to secant-secant theorem,
(PB)(PA)=(PD)(PC)
(7)(12)=(PD)(14)
NOW
84/14 = PD
PD = 6
Answer that goes in the box on the left: 2
Answer that goes in the box on the right: 4
--------------------------------------------------------
The slope is 2 since each time x increases by 1, y increases by 2. Or put another way, each time we go up 2 units, we move to the right 1 unit.
So that's why 2 goes in the box on the left.
You can use the slope formula m = (y2-y1)/(x2-x1) to get the same result
The line goes through 4 on the y axis, so this is the y intercept and the value you type into the second box (box on the right).
Recall that y = mx+b is the general slope intercept form
m = slope = 2 = 2/1
b = y intercept = 4
The equation y = mx+b turns into y = 2x+4. This is known as a linear equation as it produces a straight line graph.
If 90 is 80% of the whole value, then 1/4 of 90 added to 90 will be the value, because 1/4 of 80% (which is 20%) added to 80% will give us 100%
So,
90/4=12.5
90 + 12.5=102.5
At least, that's my take on it
