Alrighty, so, for the first one the y-intercept is the point on the graph in which the line travels through the y-axis. So the answer is 4 for the first one. For the second one the answer is f(x)=1/2x+3. I recommend Desmos: https://www.desmos.com/calculator It's highly helpful and me and my teachers use it when I do precal.
Hope this helps!

Find the area of a parallelogram with sides of 6 and 12 and an angle of 60°.
Anna007 [38]

ANSWER

36√3 square units.

EXPLANATION

The area of a parallelogram is obtained by multiplying the base by the height.

We use the sine ratio to obtain the height.

\sin(60 \degree)  =  \frac{h}{6}

h = 6 \sin(60 \degree)

h = 3 \sqrt{3}

The area becomes:

12 \times 3 \sqrt{3}  = 36 \sqrt{3} {units}^{2}

What is 3x-10+2x+3x+x+20+2x+10+x-20
kodGreya [7K]

Answer:

12x

Explanation:

3x − 10 + 2x + 3x + x + 20 + 2x + 10 + x − 20

= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20

Combine Like Terms

= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20

= (3x + 2x + 3x + x + 2x + x) + (-10 + 20 + 10 + −20)

= 12x
