Answer:
x = -1
Step-by-step explanation:
x - 9.5 = -10.5
x = -10.5 + 9.5
x = -1
Solve for x
-2x + 4 = 6x - 12
Answer:
x=2
Step-by-step explanation:
-2x+4=6x-12 Add 2x to both sides.
+2x +2x
4=8x-12 Add 12 to both sides.
+12 +12
16=8x Divide by 8 on both sides.
/8 /8
2=x
Hope this helps you out and have a great day (～^▽^)～
Answer:
x=2
Step-by-step explanation:
-2x + 4 = 6x - 12
First add 2x to each side: 4=6x−12+2x
Now simplify 6x-12+2x: 4=8x-12
add 12 to both sides: 4+12=8x
Simplify 4+12: 16=8x
Divide both sides by 8: 16/8
you end up with x=2
Hope this helps :)

A line passes through (0,4) and (3,0). Which equation does not represent the equation of this line?
a
y - 0 = - 4/3 (x - 3)
b
y = - 4/3x + 3
c
y - 4 = - 4/3 (x - o)
d
x/3 + y/4 = 1
e
4x + 3y = 12
Answer:
A
Step-by-step explanation:
use both points to find the slope using the equation
y2-y1/x2-x1, so , -2-4/2-0 = -6/2 = -3. slope or m = -3
then the y int can be any y point, so either -2 or 4. in this case they used 4.

the massive rear tire of a tractor rotates and moves the tractor 100 yards across a field in 4 minutes. Determine the linear velocity of the outer edge of the massive tire. Is the linear velocity of the outer edge of the smaller tire faster or slower than the massive tire? Which has a greater angular velocity?
9514 1404 393
Answer:
a) 25 yards per minute
b) linear velocity is the same
c) smaller tire has greater angular velocity
Step-by-step explanation:
a) The linear velocity of the edge of the tire is the same as the linear velocity of the tractor: (100 yd)/(4 min) = 25 yd/min
__
b) All parts of the tractor have the same linear velocity. The outer edge of the smaller tire is moving at the same linear velocity.
__
c) Because the smaller tire must make more turns to cover the same distance in the same time, its angular velocity (turns/time) is greater.
The smaller tire has greater angular velocity.
