Answer:
Step-by-step explanation:
Using first equation in the second gives you
x-3(-2x+1)=11
x+6x-3=11
7x-3=11
7x=14
x=2, making y=-2x+1 become
y=-2(2)+1
y=-4+1
y=-3 so the solution is the point
(2,-3)
Option A is right answer that is write a linear function that expresses the book value of the computer as the function of its age. (slop-intercept form)
In y = mx + b form, the slope is in the m position and the y int is in the b position.
y = mx + b...slope(m) = 1/3....y int (b) = -1
y = 1/3x + (-1) or y = 1/3x - 1
Answer:
x < 23 (x is less than 23)
Step-by-step explanation:
x - 3 < 20
x < 20 + 3
x < 23 (x is less than 23)
