Find the rate of change, (y2-y1)/(x2-x1), from the data given...
(2.16-1.26)/(12-7)=0.18
(1.26-0.72)/(7-4)=0.18
Since the rate is constant, this is a linear equation of the form y=mx+b. Furthermore, since 0 pencils cost 0, b=0, so the cost of the pencils is simply the number of pencils times 18 cents...
c(p)=0.18p (cost with respect to pencils is 0.18 times the number of pencils)
2/5 in percentage is 40%. Since 5/5 represents 100%, 100 divided by 2/5 is 40. Thus 2/5 is 40%
Answer:
A. <BED and <DEA, <AEC and <BEC
Step-by-step explanation:
Supplementary angles add up to give 180°.
m<BED = 90°
m<DEA = 90°
m<BED + m<DEA = 180°
Therefore, <BED and <DEA are supplementary.
m<AEC = 90°
m<BEC = 90°
m<AEC + m<BEC = 180°
Therefore, <AEC and <BEC are supplementary.
The points after Dilation are (0,0), (9,-3), and (9,9).
<u>Step-by-step explanation:</u>
The given points are A(0,0), B(3,-1), and C(3,3).
The scale factor is 3.
(
) = scale factor × (
) .
If the triangle starts form the origin (0,0) retains the same after the dilation.
= (0,0).
For point B(-1,3),
= 3 × (3,-1).
= (9,-3).
For Point C(3,3),
= 3 × ( 3,3).
= ( 9,9).
Refer the graph for dilated triangle.
What table? Maybe if you include the table and the question I could help you more
