Answer:

40. C. 40
41. B. ∠ACE ≅ ∠ECB

Step-by-step explanation:

The triangle with angle x is isosceles as two sides marked as same.

The two angles opposite to equal sides measure x.

<u>Sum of interior angles of the triangle is:</u>

100 + 2*x = 180
2x = 180 - 100
2x = 80
x = 40

Common angle of the two triangles is angle C.

Correct choice is B

mario62 [17]

Answer: Y-1=-1/8(X-3)

Step-by-step explanation:

Point slope form is Y-y1=m(x-x1)

the slope here is 2-1/-5-3 = 1-/8

so its Y-1=-1/8(X-3)

Which equation could be solved using the graph above?

nevsk [136]

Answer:

Option 3

Step-by-step explanation:

we are given the graph of a parabola

with vertex at (0,-1) and symmetrical about y axis and also open up.

Hence the equation of the graph would be transformation of $y=x^2$

by a vertical shift of 1 unit down.

So new equation after transformation would be

$y+1=x^2$

Or $y=x^2-1$

Hence option 3 is right choice.

Verify:

Put Solving the equation we get

$x^2=1$

$x=±1$

In the graph x intercepts are the same as -1 and 1

Hence our answer is right.
