Answer:
Slope = 2, Y-intercept = (0, 5)
Step-by-step explanation:
First, isolate y by moving all other terms to the other side of the equation.
2y - 4x - 10 = 0 ⇒ 2y = 4x + 10 ⇒ y = 2x + 5
The coefficient next to the x tells you the slope and the constant on the end tells you the y-intercept.
Therefore, the slope is 2 and the y-intercept is (0, 5).
First, simplify this system:
<span>2x = -10y + 6 and x + 5y = 3
by dividing the first equation by 2. Result: </span><span>x = -5y + 3
Subbing this into the 2nd equation, -5y + 3 + 5y = 3
This equation is always true, so this system has infinitely many sol'ns.</span>
Answer:
D. 31
Step-by-step explanation:
To find the mean of any group of numbers, you simply add up all the numbers and then divide by how many numbers there are.
Using a calculator or a pencil, add the following:
27 + 28 + 30 +28 + 28 + 31 + 29 + 33 + 28 + 28 + 31 + 33 + 41 + 41 + 25
= 461
The last step is to divide 461 by 15:
461/15 = 30.73
Round 30.73 to the nearest whole number and you get D. 31
Answer:
(0, -2)
Step-by-step explanation:
The slope equation is written as y = mx + b where m is the slope and b is the y-intercept. In this equation the slope, which is m, is -2/3 and the y-intercept is -2, which is the value of b. So the y-intercept on the graph would be found at point (0, -2)
