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
-3x + 5 > 17 |subtract 5 from both sides
-3x > 12 |change the signs
3x < -12 |divide both sides by 3
<h3>x < -4</h3>
Answer:
F = -44. I have attached the work too
Answer:
58
Step-by-step explanation:
you can find the height of this trapezoid by using the pythagorean theorem where the hypotenuse is 18 and one leg is 8 (33-25)
let x = height
+
= 
= 324 - 64
= 260 therefore, x =

or 2
A =
h x (sum of the bases)
bases are 25 and 33
A = (2
