Solve 7x + 2 < 9x - 4

Alexus [3.1K]

Answer:

$\boxed{\bold{x>3}}$

Step By Step Explanation:

Subtract 2 From Both Sides

$\bold{7x+2-2$

Simplify

$\bold{7x$

Subtract 9x From Both Sides

$\bold{7x-9x$

Simplify

$\bold{-2x$

Multiply Both Sides By -1 (Reverse Inequality)

$\bold{\left(-2x\right)\left(-1\right)>\left(-6\right)\left(-1\right)}$

Simplify

$\bold{2x>6}$

Divide Both Sides By 2

$\bold{\frac{2x}{2}>\frac{6}{2}}$

Simplify

$\bold{x>3}$

Solve triangle ABC, when A= 6, B=10 and c=12

valentinak56 [21]

Use cosine rule,

cos(A)=(b^2+c^2-a^2)/(2bc)
=(10^2+12^2-6^2)/(2*10*12)
=13/15
A=29.926 degrees.................................(A)

cos(B)=(c^2+a^2-b^2)/(2ca)
=(12^2+6^2-10^2)/(2*12*6)
=5/9
B=56.251 degrees.................................(B)

cos(C)=(a^2+b^2-c^2)/(2ab)
=(6^2+10^2-12^2)/(2*6*10)
=-1/15
C=93.823 degrees.................................(C)

Check:29.926+56.251+93.823=180.0 degrees....ok
