An equation in the form

is the line
that goes through the origins and whose tangent equates

. In general, any equation in the form

is the equation of a line.
Answer: OPTION C.
Step-by-step explanation:
For this exercise it is important to remember the following:

Knowing this and based on the information provided in the exercise, you can make the conversion from kilograms to ounces. This is:

According to the exercise, Miriam's procedure was:

So you can identify that she made a mistake.
Notice that:
1. Miriaim multiplied correctly.
2. Butt the third fraction should be
and not
.
We know that
<span>applying a rule of three</span>
if <span>1 japanese yen -------------> equals 0.0079 euros
X </span> japanese yen--------------> 1 euro
x=[1 euro]*[1 japanese yen]/[0.0079 euros]------------> 126.58 japanese yen
the answer is
126.58 japanese yen
Note that: (10x - 61) & (x + 10) are supplementary angles, and (10x-61) & (18y + 5) are vertical angles
10x - 61 + x + 10 = 180
Simplify
11x - 51 = 180
Isolate the x
11x - 51 (+51) = 180 (+51)
11x = 231
Divide 11 from both sides
11x/11 = 231/11
Divide
x = 21
180 = 18y + 5 + x + 10
180 = 18y + 5 + (21) + 10
Simplify
180 = 18y + 36
Subtract 36 from both sides
180 (-36) = 18y + 36 (-36)
144 = 18y
Divide 18 from both sides
144/18 = 18y/18
y = 144/18
y = 8
x = 21, y = 8 are your answers
hope this helps
The answer is A: square root.
If she knows the area is x feet squared, then you have to find the square root of the number, to find the side length. Hope that helps!
