If m angle RTS = 8x + 18, find x so that line TR is perpendicular to line TS

Kitty [74]

Answer:

Point T is the right angle of the triangle, so RTS = 90 degrees

8x + 18 = 90 (degrees)

8x = 72

x = 9 degrees

Solve the following inequality for the variable and graph the solution on the number line.

Likurg_2 [28]

The solved inequality is t > 12.

Divide both sides by 9 to isolate the variable.

9t becomes t, and 108 becomes 12.

We do not flip the sign because we are dividing by a positive.

Y1=4(5x-1), y2-=5x+1 and y1 is 344 more than 2 times y2

alisha [4.7K]

$y_1=4(5^x-1)$ and $y_2=5^x+1$

$y_1=344+2y_2$
$y_1=344+2(5^x+1)$
$4(5^x-1) = 344 + 2(5^x+1)$
$(4)(5^x)-4=344+2(5^x)+2$
$4(5^x)-2(5^x)=344+2+4$
$2(5^x)=350$
$5^x= \frac{350}{2}$
$5^x=175$
$log(5^x)=log(175)$
$x(log(5))=log(175)$
$x= \frac{log175}{log5}$
$x=3.21$ (rounded to two decimal places)
