Answer:
Step-by-step explanation:
Let's solve for f.
y=3x−2x2findf(3)
Step 1: Flip the equation.
−6df2inx2+3x=y
Step 2: Add -3x to both sides.
−6df2inx2+3x+−3x=y+−3x
−6df2inx2=−3x+y
Step 3: Divide both sides by -6dinx^2.
−6df2inx2
−6dinx2
=
−3x+y
−6dinx2
f2=
3x−y
6dinx2
Step 4: Take square root.
f=√
3x−y
6dinx2
or f=−√
3x−y
6dinx2
Answer:
f=√
3x−y
6dinx2
or f=−√
3x−y
6dinx2
(Assuming dogs have 4 feet, birds have 2 and buyers have 2)
One possibility is 4 dogs, 2 birds and 2 buyers [16 + 4 + 4]
Answer:
r = 10
Step-by-step explanation:
Solve for r by simplifying both sides of the equation, then isolating the variable.
Answer:
y= -2x
Step-by-step explanation:
To find the slope, convert the standard form of the equation into slope intercept form, y=mx+b.
5x-10y=-12
-10y=-5x-12
y=1/2 x + 1.2
The slope is 1/2 and the slope of the new line will be -2 because the negative reciprocal create a perpendicular line. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-8)=-2(x--4)
y-8=-2(x+4)
y-8=-2x -8
y= -2x +0
