What equation has a slope of 2 and goes through the point (3, 2)?
kaheart [24]

Answer:

y = 2x - 4

Step-by-step explanation:

We'll write our equation in y = mx + b form, with m being the slope and b being the y-intercept. We already know our slope, so we can replace m with 2 like this: y = 2x + b. But we don't know what b is. We can use the point (3, 2) to figure out b's value, since it has an x-value (3) and a y-value (2):

2 = 2(3) + b

2 = 6 + b

-4 = b

So we have y = 2x + (-4), or y = 2x - 4.

Hopefully that was helpful! If you have more questions, let me know.

-9f +19-1 + f) 12-=8f <br>is this the answer? ​
jeka94

Hi!

-9f + 19 - 1 + f is actually -8f + 18.

To do this we add like terms, -9f and f; and 19 and -1

-9f + f is -8f

19 - 1 is 18

Therefore your answer is -8f + 18

Find the value of x in the following diagram.
boyakko [2]

Answer:

x = 3.5

Step-by-step explanation:

By definition, congruent chords are equidistant from the center of a circle. We are given two congruent chords and their distances(the lines perpendicular), meaning those distances must be equal. We set set up an equation to model the situation:

x + 8 = 3x + 1

8 = 2x + 1

2x = 7

x = 3.5
