Answer: I think it's the 2nd option

Step-by-step explanation: (y=3) on the graph would be right between 4 and 2, going Horizontally across the graph

The (y=2x−1) goes diagonally down the graph: intercepting with the numbers shown on the following question

Also according to my calculations, the line is diagonally on the y intercept just like the second option

Neporo4naja [7]

Answer:

  about 0.0143 microfarads

Step-by-step explanation:

The effective capacitance of capacitors in series is the reciprocal of the sum of their reciprocals:

  1/(1/0.02 +1/0.05) = 1/(50+20) = 1/70 ≈ 0.0143 . . . microfarads

What is the value of side "a" in the triangle shown below?
maks197457 [2]

Answer:

a = 5

Step-by-step explanation:

Since the triangle is right use the sine ratio to solve for a and

sin30° = \frac{1}{2}, thus

sin30° = \frac{opposite}{hypotenuse} = \frac{a}{10}, hence

\frac{a}{10} = \frac{1}{2} ( cross- multiply )

2a = 10 ( divide both sides by 2 )

a = 5

Slove the system of the linear equations by either sus substitution or elimination 8x-12y=20 4x-4y=-4
marissa [1.9K]

Answer:

x = -8 and y = -7

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

8x−12y=20;4x−4y=−4

Step: Solve8x−12y=20for x:

8x−12y+12y=20+12y(Add 12y to both sides)

8x=12y+20

8x

=

12y+20

(Divide both sides by 8)
