Answer:

A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides.

By law of the sine we have:
sine (y) /35.2=sine (95) / 86
Clearing we have:
sine (y) = (sine (95) / 86) * (35.2)
y = asine ((sine (95) / 86) * (35.2))
y = 24.0632456
Rounding:
y = 24 degrees
Answer:
The answer for this case is given by:
y = 24 degrees
option 1

Answer:

Yes

Step-by-step explanation:

The two rules for a proportional relationship are

The line is straight (Check)
The line goes though the origin (Check)

Because of that it is a proportional relationship.

Hope this helps :)

Answer:

(-2, 4)

Step-by-step explanation:

One of the equations is already solved for y, so let's solve the other one for y and by the transitive proprerty of equality, if y = y, then what those y's are equal to are equal to each other. Solving the first equation for y:

x + y = 2 so

y = -x + 2

Let's fill that in for y in the second equation. Where

$y=\frac{1}{2}x+5$ , making the substitution,

$-x+2=\frac{1}{2}x+5$

Combining like terms and getting the x on one side and the constant on the other side of the equals sign:

$-\frac{3}{2}x=3$

The product of a fraction and its reciprocal is 1 so we will multiply both sides by

$-\frac{2}{3}$ to get:

$(-\frac{2}{3})(-\frac{3}{2})x=(3)(-\frac{2}{3})$

and we end up with x = -2.

Now that we know that, we can sub that in for x in either one of the original equations. I chose the first one:

If x + y = 2, then -2 + y = 2

and y = 4

Therefore, the solution set is (-2, 4)

If the equation shows a straight line then it’s a linear equation if the equation doesn’t shows a straight line then it’s non linear
