Write the equation in y-intercept form slope 2 passes through point (5,-2)
Alenkinab [10]
<h2>Answer</h2>

The equation is y = 2x - 12

<h2>Explanation</h2>

Equation in slope intercept form is

y = mx + b

Where,

m = slope

b = y-intercept

Putting the value of slope in this equation:

y = 2x + b

From this we can solve the equation for b

b = y - 2x

b = -2 - 2(5)

b = -12

Now, the equation of y-intercept becomes

y = 2x - 12

M is between points C and Q. CM=17 and CQ=21. What is MQ?

C_______M_________Q
|___________________|
             21

therefore, CM + MQ = CQ
17 + MQ = 21
MQ = 21 - 17
MQ = 4 <===

Two sides of a triangle are 8cm and 12cm. Which of the following CANNOT be the measure of the third side,
blondinia [14]

Answer:

4 cannot be the measure of the third side. This is because of the Triangle Inequality Theorem, which states that the sum of two sides of a triangle must be greater than the third side (A+B>C, A+C>B, B+C>A) In this example, if side C were 4, side C (4) plus side A (8) would be 12. Since side B is 12, and 12 cannot be greater than 12, 4 would not work.

Answer=8
