What is the solution to the linear equation 2.8y+6+0.02y=5y-14

1 answer:

6 0

Group all the 'y' terms on the left and all the other terms on the right:

<span>2.8y+6+0.02y=5y-14 => y(2.8+0.02-5)=-14-6

Now add up 2.8, 0.02 and -5; then combine -14 and -6. Can you now solve for y?

Angle 0 lies in the second quadrant and sin 0 = 3/5 cos= coy =

Elza [17]

Consider the right triangle ABC with legs AB=4, AC=3 and hypotenuse BC=5. Angle B has
$\sin B=\frac{opposite}{hypotenuse} = \frac{3}{5}$ and
$\cos B = \frac{adjacent}{hypotenuse} = \frac{4}{5}$ .

Since O lies in second quadrant $\cos O\ \textless \ 0$ and
$\cos O= -\cos B =- \frac{4}{5}$ .
Answer: $\cos O=- \frac{4}{5}$ .

Explain the error. A student was given a graph and asked to use the vertical line test

11111nata11111 [884]

Answer:

The answer is C.

There is a horizontal line test but the question asks to use the vertical line test. Using the horizontal line test you would get that the function is not one to one but using the vertical line test you would get its one to one.
