Bruh- can someone pls help me out kindly I will give 13 points
ycow [4]

Answer:

\huge\boxed{\texttt{Yes. Explanation for why.}}

Step-by-step explanation:

If we have the equation y = \frac{1}{2}x - 4 and we want to test if the point (4,–2) satisfies the equation, we can plug the x and y values into the equation and see if they make the equation true.

4 is the x value, -2 is the y.

-2 = (\frac{1}{2}\cdot4)-4

-2 = 2 - 4

-2 = -2

So this does satisfy the equation.

Hope this helped!

30 meter building casts a shadow the distance from the top of the building to the tip of the shadow is 37 M find the length of t
Pavlova-9 [17]

Answer:  22 meters

<u>Step-by-step explanation:</u>

Draw a picture of a right triangle and label the height as 30 meters and the hypotenuse as 37 meters.  Use the Pythagorean Theorem to find the base (the length of the shadow).

a² + b² = c²

x² + 30² = 37²

x²          = 37² - 30²

x²          = 1369 - 900

x²          = 469

√x²       = √469

        x = 21.656

        x ≈ 22

Which algebraic expression represents “Marcus ran four times as far this week”? 4 + n 4n n – 4
disa [49]

Answer:

The Answer would be 4n

Step-by-step explanation:

Since Marcus ran four times as far this week, we need to know how far he ran last week in order to solve this expression. Since we do not know this information it becomes our variable (n). From the statement we can also infer that there is multiplication since he states the word "times". Therefore our Algebraic Expression would be the following.

P = 4n

P being distance ran by Marcus, and n being distance ran last week by Marcus.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
