The inequality would start out looking like this:
$-30\ \textless \ \frac{5}{9} (F-32)\ \textless \ 130$
Now it's just a matter of solving the inequalities simultaneously. Get rid of the fraction by multiplying everything by 9:
$-270\ \textless \ 5(F-32)\ \textless \ 1170$
Then distribute the 5 into the parenthesis:
$-270\ \textless \ 5F-160\ \textless \ 1170$
Now add 160 everywhere:
$-110\ \textless \ 5F\ \textless \ 1330$
and finally divide everything by 5:
-22<F<266

TV=3x-24 and VX=2x+1. What is the value of VX? 1. 25 2. 99 3. 5 4. 51

Maslowich

ΔTXV is an isosceles triangle because ∡T = ∡X therefore TV = VX.

3x - 24 = 2x + 1 |subtract 2x from both sides

x - 24 = 1 |add 24 to both sides

x = 25

Given f(x) = 2 sin x, find the exact value of f (7pi/6) in simplest form with a rational denominator.

IrinaVladis [17]

Answer:

$\bold{f(\frac{7\pi}6)=-1}$

Step-by-step explanation:

$f(\frac{7\pi}6)=2\sin(\frac{7\pi}6)=2\sin(\frac{7\pi}6)=2\sin(\pi+\frac{\pi}6)=-2\sin(\frac{\pi}6)=-2\cdot\frac12=-1$
