Answer:

SAS

Step-by-step explanation:

Given: Two triangles ΔABD and ΔDCA,

We have, AD=AD (normal)

∠A=∠A (Given)

BA=CD (Sides inverse to rise to points are consistently equivalent)

With the SAS rule of congruency,

ΔABD≅ΔDCA

Look at the graph below.<br> what is the slope of the line ?

kykrilka [37]

Answer:

The slope is $-\frac{1}{5}$ .

Step-by-step explanation:

Choose 2 points on the graph.

(7,3) and (2,2)

Use slope formula: $\frac{y2-y1}{x2-x1}$

$\frac{2-3}{2-7}$ = $\frac{-1}{-5}$

The slope is $-\frac{1}{5}$ .

Help me with this plz!,

Pie

Answer:

$\frac{12}{27}$ Simplified version

Step-by-step explanation:

$(\frac{4}{5} + \frac{1}{3})$ × $\frac{5}{9}$

The first step would be to add together what is in the parenthesis. Make sure that both fractions have the same denominator. In this problem they don't, so we have to find the least common number that they both have. The number here would be 15. 5 × 3 = 15 and vise versa.

$((\frac{4}{5} x \frac{3}{3}) + (\frac{1}{3} x \frac{5}{5}))$ × $\frac{5}{9}$

$(\frac{12}{15} + \frac{5}{15})$ × $\frac{5}{9}$

$(\frac{17}{15}$ × $\frac{5}{9}$ Multiply straight across (denominators do <u>NOT</u> need to be the same)

$\frac{85}{135} = \frac{12}{27}$
