The value of the function when x = 1/2 is r(1/2) = 3 2/3

<h3>How to evaluate the function?</h3>

The equation of the function is given as:

r(x) = -2/3x + 4

The equation r(x) = r(1/2) means that

x = 1/2

Substitute x = 1/2 in r(x) = -2/3x + 4

r(1/2) = -2/3 * (1/2) + 4

Evaluate the product

r(1/2) = -1/3 + 4

Evaluate the difference

r(1/2) = 3 2/3

Hence, the value of the function when x = 1/2 is r(1/2) = 3 2/3

dmitriy555 [2]

Answer:

$\frac{f}{2} +9=4$

Subtract 9 from both sides:

$\frac{f}{2}+9-9=4-9$

$\frac{f}{2} =-5$

Multiply both sides by 2:

$2*\frac{f}{2} =-5*2$

$f=-10$

One angle of a right triangle measures 80 degrees. what is the measure of the other acute angle

Tanya [424]

Answer:

10 degrees

Step-by-step explanation:

Since a right angle is 90 degrees in total, to find the missing degree subtract 80 from 90.

90-80=10 degrees

Mario claims that if the dinominator of a fraction is a prime number, then its decimal form is a repeting decimal. Do you agree?

vodomira [7]

Answer:

I do not agree because Mario's claim is not general.

Step-by-step explanation:

Prime numbers: These are a set of numbers that are divisible by 1 and itself only. Examples are: 2, 3, 5, 7. 11 etc.

And a denominator is the divisor in a given fraction.

Considering the following fractions whose denominators are prime numbers:

$\frac{2}{3}$ = 0.66666666...

$\frac{1}{7}$ = 0.142857142

$\frac{5}{11}$ = 0.45454545...

$\frac{3}{13}$ = 0.23076923

$\frac{1}{7}$ = 0.142857142

It could be observed that Mario's claim is not a general principle which is applicable to all fractions with a prime denominator. Thus, I do not agree with his claim.
