A.

A function cannot have the more than one of the same x-values (x= 2 y=4, x=2 y=5), but you can have more than one of the same y-value as long as it’s a diff x-value (x=2 y=5, x=3 y=5)

What is the solution to this system of equations? -5.9 x-3.7 y = -2.1. 5.9 x + 3.7 y = 2.1. a. (0, Negative 2.1) b.(0, 2.1) c. i
fenix001 [56]

Assuming your system of equations is

\begin{cases}-5.9 x-3.7 y = -2.1\\ 5.9 x + 3.7 y = 2.1\end{cases}

The answer is C. Infinitely many solutions. If my assumption is incorrect, then the answer will be likely different.

The reason why it's "infinitely many solutions" is because the first equation is the same as the second equation. The only difference is that everything was multiplied by -1. You could say that both sides were multiplied by -1.

Both equations given graph out the same line. They overlap perfectly yielding infinitely many solution points on the line.

The measure of each interior angle of a regular polygon is 120°. Find the number of sides.
Archy [21]

Answer:

6

Step-by-step explanation:

You can memorize these for the smaller shapes

for equilateral polygons:

triangle: 60

square: 90

pentagon: 108

hexagon: 120

Otherwise, I believe the formula is the total degrees in a polygon (s-2)*180 where s is the number of sides.

So the measure of each angle on average would be (s-2)*180/s.

There (s-2)*180/s = 120

180(s-2) = 120s

180s-360 = 120s

60s = 360

s = 6

How many solutions are there to the equation below?
Pepsi [2]

Answer:

C

Step-by-step explanation:

This is a linear equation in one variable and has 1 solution

12x + 6 = 5x ( subtract 5x from both sides )

7x + 6 = 0 ( subtract 6 from both sides )

7x = - 6 ( divide both sides by 7 )

x = - \frac{6}{7} ← 1 solution

AREA ADDITION AND SUBTRACTION ASSISTANCE?
Tom [10]

The shaded area is a segment. The area of a segment is

A_{segment}=A_{sector}-A_{triangle}.

You know radius that is the side of isosceles triangle and measure of angle between two equal triangle sides, then

A_{triangle} =\dfrac{1}{2} a\cdot a \sin \alpha=\dfrac{1}{2} 18.6\cdot 18.6 \cdot  \sin 123^{\circ}=172.98\cdot  \sin 123^{\circ}=145.07 sq. m..

The area of sector is A_{sector}=\dfrac{r^2\cdot \alpha}{2}= \dfrac{(18.6)^2\cdot 0.68\pi}{2}=117.63\pi=369.53 sq. m..

Then A_{segment}=369.53-145.07=224.46 sq. m.

Answer: A_{segment}=224.46 sq. m.
