The last step would be what you want to prove which is a. AC ≠ CE

The only answer that has a as the last step is C.

The answer would be: C. b, d, e, c, a

Answer:

Step-by-step explanation:

b) Assume AC = CE

d) Since C is the MP of BD,

BC = CD

e) AC = CE,

AC - BC = CE - CD

c) AB = DE which is not true

a) Hence our assumption was

incorrect that AC = CE. Therefore,

AC ≠ CE

Help me find the scale factor

Andrews [41]

Answer:

1.5

Step-by-step explanation:

of the similar shapes you are only given the lengths of two corresponding sides, 22mm and 33mm

if you do 33/22 you get 1.5 so your scale factor is 1.5

(in order to go from the original shape to the copy times by 1.5, and divide if you know the length of the copy and want to work out the original)

What is the equation of a line parallel to 3 x plus 4 equal y and passing through open parentheses 4 comma space minus 2 close p

nekit [7.7K]

Step-by-step explanation:

since the two lines are parallel, slope of the line is Sam so it's 3.

let eqn of the line be y = 3x + b.

sub (4, -2):

4 = 3(-2) + b

b = 10

therefore, equation of the line is y = 3x + 10

Im so confused pls help

Answer:

2,3

Step-by-step explanation:

Let the first number be x

Hence, its next consecutive integer = x+1

$Reciprocal\ of\ the\ first\ integer\ = \frac{1}{x} \\Reciprocal\ of\ the\ second\ integer\ = \frac{1}{x+1} \\\\As\ we\ are\ given\ that\ their\ sums\ are\ \frac{5}{6} ,\\\frac{1}{x} + \frac{1}{x+1} = \frac{5}{6} \\\\Through\ butterfly\ method\ of\ resolving\ the\ denominators\,\\\frac{(x+1)+x}{x(x+1)} = \frac{5}{6} \\\frac{2x+1}{x^2+x} =\frac{5}{6} \\6(2x+1)=5(x^2+x)\\12x+6=5x^2+5x\\\\Now, lets\ bring\ all\ the\ terms\ in\ the\ LHS\ to\ RHS.\\\\Hence,\\0=5x^2+5x-12x-6\\5x^2-7x-6=0\\$

By Factorizing the expression on the LHS. we get it equal to :-

$5x^2-7x-6=0\\5x^2-10x+3x-6=0\\5x(x-2) + 3(x-2) = 0\\(5x+3)(x-2)=0$

Hence, we get two solutions for x, x=2, x= -3/5

As x is an integer, x=2 is the most suitable solution in this case.

Hence,

The numbers are 2,3
