Steve determines that sides DK and BC are congruent. He also measures angle K and angle C and determines that they are congruent

JulijaS [17]

Answer:

See below

Step-by-step explanation:

SAS requires two sides and the included angle to be congruent

Steve needs to measure sides EK and AC and if they are congruent, he can then complete his proof

<u>Let's find the measure of EK and AC</u>

EC = $\sqrt{(-4-4)^2 + (0-6)^2} = \sqrt{8^2 + 6^2} = \sqrt{100} = 10\\$
AC = $\sqrt{(-2 - 6)^2 + (9 - 3)^2} = \sqrt{8^2 + 6^2} = \sqrt{100} = 10$

As we see EK = AC = 10, so the proof is complete

2. Create a linear function that has a rate of change of 3 and a solution at (6, 12).

Ksivusya [100]

Answer:

$y = 3x - 6$

Step-by-step explanation:

A linear function has the following format:

$y = ax + b$

In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.

Rate of change of 3

This means that $a = 3$

So

$y = 3x + b$

A solution at (6, 12).

This means that when x = 6, y = 12. So

$y = 3x + b$

$12 = 3*6 + b$

$b = -6$

The linear function is:

$y = 3x - 6$
