Standard Form is Ax + By = C
y=2x+5
-2x+y= -2x+2x +5
-2x + y = 5
Answer -2x + y = 5
Seems like a wordplay question.
A "scale" is used for measuring length.
A different sort of "scale" is used for measuring mass.
12.25 is the scale factor if the pre image is 12 and the image is 147
Answer:
(10a+5)²= 100 a( a+1) + 25
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given
(10a+5)²
By using (a+b)² = a² +2ab +b²
= (10a)²+ 2 × 10a× 5 + (5)²
= 100a² + 100a + 25
= 100 a( a+1) + 25
X² + x¹ 11+1
--------- =. ------= 6
2. 2
y² + y¹. 5+(-3).
-------- = ---------- = 1
2. 2
So the midpoint is a) (6,1)
