Answer:
D.She did not keep the order of the points the same in the numerator
and the denominator
Step-by-step explanation:
Slope of a line is given as
Here we can see that the order of the points to be taken are in the same in numerator and the denominator
our student found the slope of the line between (8, 17) and (1, 4). and She wrote
Hence we can see that the order is not the same . It should be
Hence our answer is D.
Answer:
The additional information required to prove ΔDEF ~ ΔPQR is the value of the ratio DE/PQ which has to be equal to three-halves for ΔDEF to be similar to ΔPQR
Step-by-step explanation:
Given DF/PR = FE/RQ = 3/2
The Side Side Side, SSS, similarity theorem states that where there are two triangles that have corresponding sides that are proportional to each other, the two triangles are said to be similar
Given ΔDEF and ΔPQR, have sides DF/PR = FE/RQ, to prove that ΔDEF and ΔPQR, then the additional information required is the ratio of the third sides of the triangles which is DE/PQ.
If DE/PQ = Three-halves, the two triangles ΔDEF and ΔPQR are similar, if not, that is DE/PQ ≠ Three-halves, then the two triangles ΔDEF and ΔPQR are not similar.
Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side (not x) is sqrt(10). Using Pythagoras, we have 10+10=x^2, x=2*sqrt(5)
Answer:
F) y = 7/6 x - 7
Step-by-step explanation:
7x - 6y = 42
making y the subject of formula
7x - 6y = 42
-6y = 42 - 7x
y = - +
( remember - and - gives a positive ( +) )
-42/6 = - 7
therefore the answer is :
y = - 7 +
the answer is
<u>F) y = 7/6 x - 7</u>
