The model can be used as follows;
The model shows a total of 1 whole and 6
tenths. After regrouping 1 tenth into 10
hundredths, there is 1 whole, 5 tenths, and
10 hundredths. After crossing out 3 tenths
and 2 hundredths, there is 1 whole, 2 tenths, and 8 hundredths.
<h3>Place value</h3>

Answer:
The domain ⇒ x ∈ real number
The range ⇒ y ≥ -3
The y-intercept ⇒ (0 , -1)
Step-by-step explanation:
∵ y = 2Ix - 1I - 3
∴ y = 2(x - 1) - 3
∴ y = 2x - 2 - 3 = 2x - 5 ⇒ positive slope
∴ y = 2(-x + 1) - 3
∴ y = -2x + 2 - 3 = -2x - 1 ⇒ negative slope
∴ 2x - 5 = -2x - 1 ⇒ 4x = 4 ⇒ x = 1
∴ Y = 2(1) - 5 = -3
∴ The two lines intersect each other at (1 , -3)
∴ The domain is x ∈ real number
∴ The range is y ≥ -3
∴ The y-intercept = -1 ⇒ (0 , -1)
90 x 135% = 90 x 1.35 = 121.5 (notice that instead of finding 35% and adding it on, I included the 90 by mutliplying by 1.xx) - in this case xx - 35 since it was a 35% increase.
