Which of the following represents the inequality shown below when solved for x?

kkurt [141]

Answer:

Option C. $x < -\frac{14}{5}y$

Step-by-step explanation:

we have

$-\frac{5x}{8} > \frac{14y}{8}$

Solve for x

That means ---> isolate the variable x

Multiply by 8 both sides to remove the fractions

$-5x>14y$

Multiply by -1 both sides

Remember that

When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$5x$

Divide by 5 both sides

$x < -\frac{14}{5}y$

Let R be a ring with identity and let S be a subring of R containing the identity. Prove that if m is a unit in S then u is a un

kumpel [21]

Explanation:

Since m is a unit in S, then, there exists b ∈ S such that m*b = 1, where 1 is the identity. Since S is a subring of R we have that m ∈ R, and therefore b is also the multiplicative inverse of m in R. The converse isnt true.

The set of real numbers is a Ring with the standard sum and multiplication. Every real number different from 0 has a multiplicative inverse. For example, the inverse of 2 is 1/2. However, 2 is not a unit on the subring of Integers Z.

Please help ASAP will give brainlist.

144+64= 178

$\sqrt{178 } = 13.3$

a^2+b^2= c^2

Whenever finding a missing length use the formula up above :

a^2+b^2= c^2

a^2-b^2= c^2

144-64= 80

$\sqrt{80} = \sqrt{16 } \times \sqrt{5} = 4 \sqrt{5} = 8.9$

Answers are 13.3 and 8.9
