Solve for y 2x-5y=10
scZoUnD [109]

Answer:

y = 2/5x - 2

Step-by-step explanation:

Step 1: Write equation

2x - 5y = 10

Step 2: Solve for <em>y</em>

  1. Subtract 2x on both sides: -5y = 10 - 2x
  2. Divide both sides by -5: y = -2 + 2/5x
  3. Rewrite: y = 2/5x - 2

I need help ? which linear function is represented by the graph?​
PilotLPTM [1.2K]
<h3>Answer: f(x) = (-1/2)x+1, choice B</h3>

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

Explanation:

The diagonal line passes through 1 on the vertical y axis. So the y intercept is b = 1. This means the location of the y intercept is (0,1).

Start at (0,1) and move down 1 and to the right 2 to arrive at (2,0). This is another point on the diagonal line. The motion of "down 1 and right 2" is effectively the slope

slope = rise/run = -1/2

rise = -1, run = 2

The rise being negative means we have gone downhill as we move to the right.

With m = -1/2 as the slope and b = 1 as the y intercept, we go from y = mx+b to y = (-1/2)x+1

The last thing to do is replace y with f(x) to get f(x) = (-1/2)x+1 as the final answer.

Sarah is paid biweekly. Her annual salary is $33,000.
bezimeni [28]

Answer:

$1269.23

Step-by-step explanation:

Since Sarah is paid biweekly (every 2 weeks), and there are 52 weeks in a year...

52 ÷ 2=26

Sarah is being paid 26 weeks out of the year.

Divide 33,000 by 26 (I only list 4 places after the decimal):

33000 ÷ 26=1269.2307

Round 1269.2307 to the nearest cent (hundredth):

1269.23

disa [49]

Answer:

C. 15 votes

Step-by-step explanation:

B= votes Billy got

K = votes Keeton got

B = 3K


B+K =20

Substitute the first equation into the second equation

3K + K =20

Combine like terms

4K =20

Divide both sides by 4

4K/4 = 20/4

K =5

Keeton got 5 votes

B = 3*K

B = 3*5

B = 15 votes

Billy got 15 votes
