>, When 2=x 6 times 8-2x is 44 while 6(5+x) is 42
They consists of equations and unknown variables. There are 4 PCs and 8 Mac in the room
<h3>System of equation</h3>
They consists of equations and unknown variables
Let the number of PCs be x
Let the number of Mac be y
If Mke has 12 computers, then;
x + y = 12
If there are two Macs for every PC in his classroom, then;
y = 2x
Substitute
x + 2x = 12
3x = 12
x = 4
Recall y = 2x
y = 2(4)
y = 8
There are 4 PCs and 8 Mac in the room

Step-by-step explanation:
2x+98=180° (angles in straight line )
2x=180-98
x=2/2
x=1
Answer:
When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.
Answer:
Step-by-step explanation:
Parallel lines have the same slope.
<u>Use the given point (6, 14) and point-slope form:</u>
- y - 14 = -4/3(x - 6)
- y = -4/3x + 8 + 14
- y = -4/3x + 22
Correct choice is B
