X=-8 is the answer so it would be C
Y=12+2x
y represents the number of pieces she now knows, x represents the number of weeks she has taken lessons, 2 is the slope (the number of pieces she'll learn each week), and 12 is the y intercept (the number of pieces she knew before taking lessons).
To solve the equation for 11 weeks, we replace x with 11.
2×11+12= 24
y=24
Answer: d.=28 The last one
Step-by-step explanation:
3.3=9 +5 =14 x 2 =28
