1. One way to identify congruent triangles is to prove that their matching sides have the
same length. Triangle CDE has vertices at C(1,4), D(1, 1) and E (5, 1).
a) Graph triangle CDE
b) Find the length of side DC and side DE.
c) Reflect triangle CDE over the y-axis then translate it 2 units left. Label the
vertices of the image C'D'E'. Write the coordinates of the vertices of triangle
C'D'E
d) Find the length of side D'C' and side D'E'.
e) Using a piece of patty paper, determine if side CE is the same length as side
C'E'.
f) Are the two triangles congruent?
P

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.
