When two linear equations have only one solution the two lines on a graph would intersect each other ( they would only touch in one spot).

Make w the subject of <br> Y-aw=2w-1
Luda [366]
So you're gonna take add 1 to both sides and add aw to both sides also
y+1=2w+aw
then you factorize the w
y+1=w(2+a)
divide 2+a in both sides
y+1/2+a=w
the answer is
y+1/2+a=w

Area of the trapezoid:
\frac{12.8 + 4.2}{2} (4.9) = 41.65 cm^2

Area of the rectangle:
4.2 x 3.1 = 13.02 cm^2

Area of each quarter circle:
\frac{ \pi  (3.1)^{2} }{4} = 7.54 cm^2

We have two quarter circles:
7.54 + 7.54 = 15.08

41.65 + 13.02 + 15.08 = 69.75 cm^2

What is the domain of the function represented by the graph?
dezoksy [38]

Answer:  Choice C.  x \ge -3

============================================

Explanation:

The domain is the set of all allowed x inputs.

Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.

We can say the domain is -3 \le x < \infty which can be simplified to -3 \le x or x \ge -3

In short: x can be -3 or larger.
