The independent variable (x) is the domain
Steps to solve:
f(x) = 3x³ – 2x² + x; x = -3
~Substitute
f(-3) = 3(-3)³ - 2(-3)² + (-3)
~Solve the exponents
f(-3) = 3(-27) - 2(9) + (-3)
~Multiply
f(-3) = -81 - 18 - 3
~Subtract
f(-3) = -102
Best of Luck!
Answer:
using the first two equations cancelling the z
-2x-2y-5z=-7
6x+8y+5z=9
4x +6y= 2
using the second and the third equations cancelling the z
6x+8y+5z= 9
-2x-3y-5z= -6
4x +5y = 3
4x + 6y = 2
-4x -5y = -3
y= -1
2x + 2(-1) + 5z = 7
2x - 2 + 5z = 7
2x + 5z = 9
6x + 8(-1) + 5z = 9
6x - 8 + 5z = 9
6x + 5z = 17
-2x - 5z= -9
4x = 8
x = 2
2(2) + 2(-1) + 5z= 7
4 - 2 + 5z = 7
2 + 5z = 7
5z = 5
z = 1
(2, -1, 1)
the answer is a.

Answer:
The proportion of all correctly classified violins that are old is equal to the proportion of all new violins that are incorrectly classified.
Step-by-step explanation:
Step-by-step explanation:
y-7=4(x-2)
we need to simplify the y to het a
y-7=4x-8 (i did 4x-8 because of 4(x-2)
now y= 4x-8+(-7)
after calculating -8+(-7) IT becomes
y=4x-15
okay we have the guide Line
y=4x-15
the a is 4
because
a = {y=a.x+b}
now we need to find the points using this guide Line
y=4x-15
x= 2(you can add any number here ,we Just need to know where the point is )
y= 4(2)-15
y=8-15
y= -7
points are (2,7)
