Answer:
7
Step-by-step explanation:
Step-by-step explanation:
an expression (polynomial) with the highest exponent = n has n zeros (solutions, where y = 0, although some of them can be imaginary numbers, or some can fall together into 1 solution).
and it has max. n-1 relative extrema ("bumps" in the curve, where the curve changes direction from up to down or vice versa).
so, in our case of
f(x) = 3x⁵ - x³ + 4x - 2
we have max. 5-1 = 4 relative extrema.
(5r+2)(3r-4)
mutiply both sides together
(5r)(3r)= 15r^ 2
(5r)(-4)= -20r
(2)(3r)= 6r
(2)(-4)= -8
15r^2-20r+6r-8
Answer: 15r^2-14r-8
Answer:
2/1and6/3 because if you do cross multilication they both equal 6
Step-by-step explanation:
Answer:
y = - 2x + 11
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 )
Rearrange y + 2x = m into this form by subtracting 2x from both sides
y = - 2x + m ← in slope- intercept form
with slope m = - 2
Parallel lines have equal slope, thus
y = - 2x + c ← is the partial equation
To find c substitute (4, 3) into the partial equation
3 = - 8 + c ⇒ c = 3 + 8 = 11
y = - 2x + 11 ← equation of line
