Answer:
a = -2
Step-by-step explanation:
You first have to open the equation ie 3a + 4.5 = -1.5. you then group like terms that is 3a = -1.5 - 4.5. This gives you 3a = -6. You then divide both side by the number attached to the variable 'a' ie 3. Which is 3a/3 = -6/3 making a = -6/3 which gives you a = -2
The slope of the given line is ∆y/∆x = (4-6)/(5-1) = -2/4 = -1/2. The slope of the desired (perpendicular) line is the negative reciprocal of this, -1/(-1/2) = 2.
The point-slope form of the equation for a line with slope m through point (h, k) is
... y - k = m(x - h)
For slope 2 and the given point, your equation can be
... y + 6 = 2(x + 2)
Yes Amir should switch because it's a nickel less
Answer:
He has 386 egg laying hens.
Step-by-step explanation:
First we must take away the amount of Roosters Uncle Ben has.
440 - 39 = 401
Then we take away the amount of non-egg laying hens he has
401 - 15 = 386
Thus you get your answer:
Uncle Ben has a total of 386 egg laying chickens.
Answer:
y = 1/4x - 4
Step-by-step explanation:
If you put the equation in slope-intercept form y=mx+b, then you have y=-4x+3, so the slope is -4. Then take the negative reciprocal of that so you have the perpendicular slope 1/4. Plug in x, y, and, m into the equation and solve for b.
-3 = 1/4(4) + b
-3 = 1 + b
-4 = b, then rewrite the equation with the new slope and the b you found.
y = 1/4x - 4
