Answer: r = 1
Step-by-step explanation:
The slope of a line can be represented as 
. Plugging in the following values would provide you with:
Hope it helps :) and let me know if you want me to elaborate on anything.
AC = x, CD = 2x cause of 30° angle. Use pythagoras then
<h2><u>Solution</u>:-</h2>
• Surface area of a cylinder = 2πr(r + h) sq. units.
In the above diagram,
Radius (r) of the cylinder = 13 cm.
Height (h) of the cylinder = 39 cm.
<h3>• Taking value of π = 3.14</h3>
Hence, Surface area of the cylinder = 2 × 3.14 × 13(13 + 39)
Surface area of the cylinder = (81.64 × 52) cm²
Surface area of the cylinder = 4245.28 cm²
The surface area of the cylinder is <u>4</u><u>2</u><u>4</u><u>5</u><u>.</u><u>2</u><u>8</u><u> </u><u>cm²</u>. [Answer]
What you want to first is substitute the numbers in for the variables in the equation
Since b= -5 , we will plug it in for -b
-5 + c = -13x
Now plug in -8 for c
-5 + (-8) = -13x
Add the numbers on the left side, which gives you -13.
-13 = -13x
Lastly, divide both sides by -13x, which will give you 1.
So x = 1
Answer:
Y must be negative
Step-by-step explanation:
Use this equation as an example: 5 + -7 = negative
If you add both of them you end up with -2
-2 is a negative integer
