91 divided by 7 is 13. so he can paint 13 in 1 week. 13 x 4 equals 52 so he can paint 52 portraits in 4 weeks.
There is word form(which means write the number down, so lets just say I have the numbers 82,7,and 12. So I'll write eighty-two, seven, and twelve. There's also standard form, so lets say I have the numbers 27 and 15 I'll write 20+ 7, then 10+5.) I hope you got it! Good luck

Answer:
x = 14
Step-by-step explanation:
-1/5(x - 4) = -2
-1/5x + 4/5 = -2
-1/5x = -2 - 4/5
-1/5x = -10/5 - 4/5
-1/5x = - 14/5
x = -14/5 * - 5
x = 70/5
x = 14 <====
Answer:
The graph of f(x) passes through (1,1) , (2,1.4...), (3,1.7....),(4,2)......
As, this curve is not linear.
To find the graph of a inverse function if a function is given
As we can see that ,
√1=1
√2=1.414..
√3=1.732..
√4=2
it means, √x=y is f(x).
So, to find the inverse of f(x), follow the procedure
Squaring both sides
Replace x by y and y by x to get inverse of f(x)
So,there will be two inverses of f(x)
1. x=√y
2. x= -√y
Domain of g(x)∈[0,∞], means y≥0.
Option A, 2nd graph below. and Option B. 3 rd Graph below is true regarding graph of g(x).
Use the power, product, and chain rules:
• product rule
• power rule for the first term, and power/chain rules for the second term:
• power rule
Now simplify.
You could also use logarithmic differentiation, which involves taking logarithms of both sides and differentiating with the chain rule.
On the right side, the logarithm of a product can be expanded as a sum of logarithms. Then use other properties of logarithms to simplify
Differentiate both sides and you end up with the same derivative:
