A data table shows that as the input (x) increases by 1, the output (y) decreases by 7. When x is 0, y is –2. What is the equati

on for this function? A. y = 7x – 2 B. y = 7x C. y = –7x – 2 D. y = –7x + 2

X 0 1 2 ...
y -2 -9 -16...
(y) decreases by 7/<span> (x) increases by 1, so slope =-7,
y- int=-2
this is equation c) y=-7x-2</span>

Answer:

y = 1.44

Step-by-step explanation:

What are you aiming to do here? Please share all instructions with each problem.

If you want to solve 4.5/y = 12.5/4 for y: Multiply both sides by 4y:

18 = 12.5y. Then y = 1.44

Using the segment addition postulate, which is true? What is the measure of AngleDCF? Three lines extend from point C. The space

Flura [38]

Answer:

129

Step-by-step explanation:

If three lines CD, CE and CF extend from point C, then the following addition postulate is true;

<DCE + <ECF = <DCF

If the space between line C D and C E is 75 degrees, then <DCE = 75

If the space between lines C E and C F is 54, then <ECF = 54.

Substitute the given values into the expression above will give;

<DCF =<DCE + <ECF

<DCF = 75+54

<DCF = 129

Hence the measure of <DCF is 129°
