Answer:
negative 9 plus or minus the square root of 17 divided by 8
Step-by-step explanation:
move all terms to one side
4x^2 + 9x + 4= 0
Use the quadratic formula
and you get negative 9 plus or minus the square root of 17 divided by 8
Answer:
(f*g)(x) = 3x^3 + 6x^2
Step-by-step explanation:
Since we are looking for the result of multiplying the equations (f*g), we must multiply the right sides together
(f*g)(x) = (3x^2)(x+2)
To get from here to the solutions, we must multiply the first term by all parts in the second term
3x^2 * x = 3x^3
3x^2 * 2 = 6x^2
from there, just put them back in the equation
(f*g)(x) = 3x^3 + 6x^2
Answer:
y = -7/4x - 11
Step-by-step explanation:
formula is y = mx + b
m is the slope
b is the y intercept
y = -7/4x -11
which is the first one
Answer:
Step-by-step explanation:
if it is linear then it will be a straight line(gradient is the same)
if quadratic then curve(gradeint isnt the same)
y=mx+c
m=[y(2)-y(1)]/[x(2)-x(1)]
you can choose any 2 points from the table
m=2-0.4/0-1
m=-1.6
repeat but 2 different coordinates
m=0.4-0.08/-1--2==>-2.24
m=-2.24
different coordinate therefore quadratic
cant be exponential, because nothing is being raised to some power
Answer: the second one
Step-by-step explanation:
Because this equals x > -5
So the circle would be open with the arrow pointing to the right starting at -5
