Four tenths is 0.4 while four hundredths is 0.04. Four tenths is ten times the amount of four hundredths.
The roots on the graph is basically the x-intercepts So if you see points that are on the x-axis then those are the roots.
Ex
x=0, x=-2 x=3 etc. <span />
Answer:
C. AB=CD not necessarily true
Step-by-step explanation:
A.
AD = DB True because the width of the compass was the same and hence the radius was same for both centers A and B
B. AE=EB True
CD makes the perpendicular bisectors if arcs are made with compass of same width
C. AB=CD . There is no property which says that it is necessarily true
D. AC=CB True because the width of the compass was the same and hence the radius was same for both centers A and B
Answer:
y = 2x + 11
Step-by-step explanation:
The first thing we need to do
is to find the slope of the line that passes through the points (-4,-3) and (4,1)
Mathematically, that would be;
m = y2-y1/(x2-x1)
where (x1,y1) = (-4,-3) and (x2,y2) = (4,1)
substituting these. values we have;
m = (1-(-3))/(4-(-4)) = 4/8 = 1/2 or 0.5
Now we are told this line is perpendicular to another line that passes through another point.
We can find the slope of this other line
Since both lines are perpendicular, the product of their slope is -1.
Thus , -0.5 * m = -1
m = -1/-0.5 = 2
So the slope of the other line is 2
Using the point-slope form;
y-y1= m(x-x1)
The point for the other line is (-4,3)
So the equation will be
y-3 = 2(x+4)
y-3 = 2x + 8
y = 2x + 11
