Answer:
A point (a, b) rotated around a point (x, y) 180 degrees will transform to point (-(a - x) + x, -(b - y) + y). A point (a, b) rotated around the origin 270 degrees will transform to point (b - y + x, -(a - x) + y).
Step-by-step explanation:
Hi,
Let's solve the equation step by step.
6(a+3)=18+6a
Step 1: Simplify both sides of the equation.
6(a+3)=18+6a
(6)(a)+(6)(3)=18+6a(Distribute)
6a+18=18+6a
6a+18=6a+18
Step 2: Subtract 6a from both sides.
6a+18−6a=6a+18−6a
18=18
Step 3: Subtract 18 from both sides.
18−18=18−18
0=0
Answer:
All real numbers are solutions.
Have a great day!
Answer:
y= 3/5 x + 4
Step-by-step explanation:
the difference between (0,4) and (-5, 1) is the slope of 3/5. you add the intercept at the end and boom! equation!
Answer:
Original height = 144 cm
Increase height = 148.5 cm
Change in height = 148.5 - 144 = 4.5 cm
Percentage change = change/original ×100
= (4.5 / 148.5) × 100
= 3.03%
The height increased by 3.03%.
