The answer is y=3x-7.
Sorry the picture is a bit blurry but basically, you use the points given (5,8) and plug it into the equation y=mx+b. They already give you the slope, 3, so you need to find the y-intercept. To do so, plug in and solve. You’ll get -7=b, so the equation is y=3x-7.

Answer:

The answer is: y = 3x - 7

Step-by-step explanation:

Given point: (5, 8).

Slope m = 3

Use the point slope form and solve for y:

y - y1 = m(x - x1)

y - 8 = 3(x - 5)

y - 8 = 3x - 15

y = 3x - 15 + 8

y = 3x - 7

Proof:

f(x) = 3x - 7

f(5) = 3(5) - 7

= 15 - 7 = 8, giving (5, 8)

If mZDCB = 140°, then mZACD = [?]° !!!PLS HELP I WILL MARK BRAINLIEST !!!

Readme [11.4K]

Answer:

40°

Step-by-step explanation:

$m\angle DCB +m\angle ACD = 180\degree$ (Linear pair angles)

$\implies 140\degree +m\angle ACD = 180\degree$

$\implies m\angle ACD = 180\degree-140\degree$

$\implies m\angle ACD = 40\degree$

A dog sits at a corner of a square with side length 44 meters. the dog runs 10 meters along a diagonal toward the opposite corne

wlad13 [49]

Refer to the figure given below while reading the solution.

Suppose the dog reaches position A when traveled 10 m diagonally towards the opposite side.

And then position B when traveled 5 m towards the right turning 90°.

We can observe that APC is a right triangle with legs of equal length AC. And the coordinates of the point A is (AC, AC).

Also we can observe that APB is a right triangle with legs of equal length AD. Then the coordinates of the point D is (AC, AC-AD).
Hence, the coordinates of B will be (AC+AD, AC-AD).

Now, we since we have the coordinates we can calculate the shortest distances of B from each of the sides.
