Answer:
y = - x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 2 ← is in slope- intercept form
with slope m = 1
Given a line with slope m then the slope of a perpendicular line is
= -
= -
= - 1, hence
y = - x + c ← is the partial equation of the perpendicular line
To find c substitute (4, - 1) into the partial equation
- 1 = - 4 + c ⇒ c = - 1 + 4 = 3
y = - x + 3 ← equation of perpendicular line
Answer:
the 1st answer is H, yw
Step-by-step explanation:
quadrant I is on the top right, quadrant II is on the upper left, quadrant III is on the bottom left, and quadrant IV is on the bottom right. H is located in the top left (quadrant 2)
200.85in
This is because
25.12^2 = 631
631/π = <span>200.85
</span>
Therefore the diameter would be <span>200.85in</span>
B. Subtract both numbers to find the refund amount
Answer:
19 birds
Step-by-step explanation:
First, I wrote my two equations:
5.5x +8.5y = 291.5
x + y = 41
Next, I got the variable y by itself in the second equation. Subtract x to get y = -x + 41. Then, I substituted what y equaled into the first equation. It should look like this: 5.5x + 8.5(-x+41) = 291.5. Distribute 8.5 to get 5.5x -8.5x + 348.5 = 291.5. Subtract 5.5x and 8.5x to get -3x. It should look like this: -3x + 348.5= 291.5. Subtract 348.5 from 291.5 to get -57. Now, you should have -3x = -57. Divide -3 from both sides, to get x = 19. So, there are 19 birds. If you want to go even further, 41-19= 22, which means there are 22 cats. Hope this helped!
