2a-5b=10 solve for b

1 answer:

4 0

Solve for b means that you need to separate b in one side and the other terms in the other side

2a-5b=10 subtract 2a from both sides

2a - 5b - 2a = 10 - 2a combine like terms

- 5b = 10 - 2a divide both sides by -5

b = -2 + 2/5 a

I hope that helps!

There are infinitely How many pairs of numbers of which the sum of their cube roots is zero give two of these pairs

ivanzaharov [21]

Answer:

Infinite pairs of numbers

1 and -1

8 and -8

Step-by-step explanation:

Let x³ and y³ be any two real numbers. If the sum of their cube roots is zero, then the following must be true:

$\sqrt[3]{x^3}+ \sqrt[3]{y^3}=0\\ \sqrt[3]{x^3}=- \sqrt[3]{y^3}\\x=-y$

Therefore, any pair of numbers with same absolute value but different signs fit the description, which means that there are infinite pairs of possible numbers.

Examples: 1 and -1; 8 and -8; 27 and -27.
