You can rewrite every radical as an exponent by using the following property — the top number in the resulting rational exponent tells you the power, and the bottom number tells you the root you’re taking. For example, you can rewrite 3 √(8^2<span>) as 8 (2/3).</span>

Explain what independent and dependent variables mean
g100num [7]

Answer:

please give me brainlist and follow

Step-by-step explanation:

You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.

Answer:

D. m<RST = 2(m<TSU)

Step-by-step explanation:

Given that m<RST = 76°, m<RSU = 48°, and m<TSU = 38°, this implies that:

SU is an angle bisector of angle RST. Thus,

m<RST is twice the measure of <RSU or <TSU.

Therefore, the only option that is correct is:

D. m<RST = 2(m<TSU)

What function is the inverse of y=-3x+6/7
Kisachek [45]
Y = -3x + 6/7
switch the x and y, then solve for y:
y =  -3x  +  \frac{6}{7}  \\ x =  - 3y +  \frac{6}{7}  \\ 3y =  - x + \frac{6}{7} \:
3y  \div  3 =  (- x + \frac{6}{7}) \div 3  \\  y =  - x \div 3 \:  +  \frac{2}{7}
y = -x/3 + 2/7
