4n-3=4n-2 subtract 4n from both sides
-3=-2
Since -3!=-2, there is no solution.
So your answer is a.
Answer:
(3, 3 )
Step-by-step explanation:
Under a translation < 8, 0 > then
A(- 5, - 3 ) → (- 5 + 8, - 3 + 0 ) → (3, - 3 )
The line with equation y = 0 is the x- axis
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(3, - 3 ) → (3, 3 )
Answer:
three (3)
Step-by-step explanation:
4x is the first term
-4 is the second term
3y is the third term
Answer:
The solutions to the quadratic equations will be:
Step-by-step explanation:
Given the expression
Let us solve the equation by completing the square
Add (-6)² to both sides
simplify
Apply perfect square formula: (a-b)² = a²-2ab+b²
i.e.
so the expression becomes
solve
add 6 to both sides
Simplify
also solving
add 6 to both sides
Simplify
Therefore, the solutions to the quadratic equation will be:
Answer:
7
Step-by-step explanation:
An easy way to find any percentage of a number is to multiply with decimals. To do this you have to first convert the percentage to a decimal. Do this by moving the decimal point in the percentage 2 places to the left. This means that 2.0% becomes 0.02. Then, multiply this decimal by the whole number. So, 0.02*350. This equals 7, which is 2% of 350.
This same trick will work with any problem. For example 38% of 435 is the same as 0.38*435, which equals 165.3.
