Answer:
The ratios are proportional ratios
It takes 3 days to complete one hour of reading. So 3 x 20 = 60 days total.
Answer:
y=-5
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are equal and bisect each other
so
step 1
Find the value of x
substitute the given values
solve for x
Multiply by 2 both sides
step 2
Find the value of y
we have
substitute
substitute the value of x
Answer:
7a 3 −7a+1
Step-by-step explanation: I hope this help.

Polynomial Roots Calculator :
2.1 Find roots (zeroes) of : F(a) = 7a3-7a+1
Polynomial Roots Calculator is a set of methods aimed at finding values of a for which F(a)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers a which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 7 and the Trailing Constant is 1.
The factor(s) are:
of the Leading Coefficient : 1,7
of the Trailing Constant : 1
Let us test ....
P Q P/Q F(P/Q) Divisor
-1 1 -1.00 1.00
-1 7 -0.14 1.98
1 1 1.00 1.00
1 7 0.14 0.02
Polynomial Roots Calculator found no rational roots
Final result :
7a3 - 7a + 1
Answer:
Step-by-step explanation:
We have to vertically stretch the function 
by a factor of 2.
Then the function will become 
.
Then it is reflected across the x-axis.
So, the new function will be 
.
Now, if the function is shifted down 3 units then the final function will become (Answer)
