Can you please solve AND EXPLAIN this equation: -2y is less than or equal to 2 - 2x

grin007 [14]

Answer:

$y\geq -1 + x$

Step-by-step explanation:

$-2y\leq 2-2x\\$ Divide everything by 2

$-y\leq 1-x$ Divide everything by -1 and since y is negative, you flip the sign

$y\geq -1 + x$

Answer:

Step-by-step explanation:

7 no

113+12x+7+90+90=360

300+12x=2=360

12x=360-300

x=60/12

x=5

9 no

10x-6+109+79+20x-2=360

30x+180=360

30x=360-180

x=180/30

x=6

If Logx (1 / 8) = - 3 / 2, then x is equal to

snow_tiger [21]

Answer:

Let's solve!

Step-by-step explanation:

$logx^{\frac{1}{8} } = -\frac{3}{2}$

$then$

$10^{-\frac{3}{2}} = x^{\frac{1}{8} }$

$(10^{-\frac{3}{2} })^{8} = (x^{\frac{1}{8} })^{8}$

$x = 10^{3*4} = 10^{-12}$

$x= 10^{-12}$

If the equation looks like this, then it has the solution

$x= 10^{-12}$

Another answer is

√x = 2 or x = 4

I hope this helps!
