For what value of x is 1/2 x = -9<br><br> x = 18<br> x= -4<br> x=-18<br> x= -36
Luda [366]

Answer:

x = -18

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

Multiply 2 to both sides:

(x/2) * 2 = (-9) * 2

x = -9 * 2

x = -18

x = -18 is your answer.

Deffense [45]

Answer:

170 heart beat per minute.

Step-by-step explanation:

So, if my age is 21 years i.e. x = 21, then the number of recommended heart beats per minute for my age will be

y = f(21) = - 0.85(21) + 187 = - 17.85 + 187 = 169.15 ≈ 170. (Answer)
