Answer:
Mother: 40 years old
Rakhi: 15 years old
Step-by-step explanation:
Solution :
Let present age of Rakhi = x years
Present age of Mother = 4x
5 years later
Age of Rakhi =x+5
Ag of Mother =4x+5
Given 4x+5=3(x+5)
4x−3x=15−5
⇒x=10
Mother's age =4x=40 years
Plug 10 in for x to find Rakhis age
Answer:
x² + 16x + 64
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
Here, a = x & b = 8
(x+8)² = x² + 2*x*8 +8²
= x² + 16x + 64
Its a because you have to do the change in y over the change in x which is
y2-y1
------
x2-x1
3/4% × 75
3/4 of a percent is .0075.
0.0075 times 75 = 0.5625
The answer is B) 0.5625.
Its g is increasing
I guess you could just plug in 0, 1 and -1 and graph it.
