Nataly_w [17]3 years ago
5 0

Answer:

3x - 18 = 2y

5x - 6y = 14

5x - 3*(2y) = 14

5x - 3*(3x - 18) = 14

5x - 9x + 54 = 14

-4x = -40

x = 10

3*10 - 18 = 2y

30 - 18 = 2y

12 = 2y

y = 6

You invest $1600 in an account paying 5% interest compounded daily. What is the account's effective annual yield? Assume 360 day
Pavlova-9 [17]

Answer:

5.13%.

Step-by-step explanation:

Amount  accumulated in 1 year

= 1600(1 + 0.05/360)^360

= $1682.03

Account's effective annual yield

= 82.03 * 100  / 1600 %

= 5.13%.

In the diagram below, PQ and RS are parallel. Based on the angle measures in the diagram, what is the value of X?
Butoxors [25]

Answer:

x would be equal to 70 grades

Step-by-step explanation:

The angle QRS is equal to 180 - 130 = 50 grades.

We add up that with the other 60 grades on the left, and we encounter ourselves with a simple equation:

60 + x + 50 = 180

x = 70

Hope this was helpful

Is the function shown in the graph one-to-one?
Cloud [144]

Answer:

  yes

Step-by-step explanation:

The graph is of a function (one output for every input) that also passes the horizontal line test (one input for every output). Hence it is one-to-one.

For a <em>function</em>, the key for it being one-to-one is that it pass the horizontal line test.

HD Straight line graphs
Taya2010 [7]

Answer:

The equation of the sraight line  3x- y+ 6 =0

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the gradient of the function

   |gradf| = 3  and point (-1,3)

Given that the slope of the line

 m = 3

The equation of the straight line passing through the point(-1,3) and slope m =3

y -y_{1} = m(x-x_{1} )

y-3 = 3(x-(-1))

y-3 = 3x+3

3x +3-y+3=0

3x- y+ 6 =0

<u><em>Final answer:-</em></u>

The equation of the sraight line  3x- y+ 6 =0

<u><em></em></u>
