Question 1016072
.
Is this supposed to be: {{{(7-5x)^1/2 >= 8}}} -OR- {{{(7-5x)^(1/2) >= 8}}} . (exponent=1/2)
.
{{{(7-5x)^1/2 >= 8}}} . Multiply each side by 2.
{{{7-5x>=16}}} . Subtract 7 from each side.
{{{-5x>=9}}} . Divide each side by -5. . (reverse inequality)
{{{x<=-(9/5)}}}
.
-OR-
.
{{{(7-5x)^(1/2) >= 8}}} . Exponent is 1/2.
{{{sqrt(7-5x)>=8}}} . Square both sides.
{{{7-5x>=64}}} . Subtract 7 from each side.
{{{-5x>=57}}} . Divide each side by -5. . (reverse inequality)
{{{x<=-(57/5)}}}
.
