What two number adds to 10 but multiply to 16

2 answers:

8 0

Let 2 nos. be x & y

x + y = 10

x * y = 16

from 1st eqn, y = 10 - x

substituting in 2nd eqn

x * (10 - x) = 16

10x - x^2 = 16

x^2 - 10x + 16 = 0

(x - 8)(x - 2) = 0

x = 8 or x =2

y = 10 - 8 = 2 or 10 - 2 = 8

so the two numbers are 2 and 8

Answer:

Step-by-step explanation:

$\bigg( \frac{16}{49} \bigg)^{ - \frac{3}{2} } \\ \\ = \bigg( \frac{49}{16} \bigg)^{ \frac{3}{2} } \\ \\ = \bigg( \frac{ {7}^{2} }{ {4}^{2} } \bigg)^{ \frac{3}{2} } \\ \\ = \bigg( \frac{ {7}}{ {4} } \bigg)^{ \frac{2 \times 3}{2} } \\ \\ = \bigg( \frac{ {7}}{ {4} } \bigg)^{ 3} \\ \\ = \frac{343}{64} \\$

What is the value of 36X negative Y over to when X equals three and Y equals -6

Rus_ich [418]

Note:

Your question is a little unclear. But, from my understanding, I assume you may be asking the evaluation of the expression 36x - y when x = 3 and y = -6.

so I will solve based on my assumption which anyways would clear your concept.

Answer:

The value of 36x - y when x = 3 and y = -6 will be: 114

Step-by-step explanation:

Given

Assuming the expression

36x - y

To Determine

Evaluate 36x - y when x = 3 and y = -6

Given the expression

$36x - y$

substitute x = 3 and y = -6 to evaluate the expression

$36x-y= 36(3) - (-6)$

$= 108+6$

$= 114$

Therefore, the value of 36x - y when x = 3 and y = -6 will be: 114
