To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.


I hope this helps thank you

The attendence at a water park varies directly as the temperature and invesely as the number of days of rain during the month. I
Margarita [4]
Let A be attendance, t the temperature and n the number of days. Then,
A\alpha\frac{t}{n}
A=k\frac{t}{n}
Where k is a constant of proportionality;
If A=3200, T=88 and n=8, then k,
3200=\frac{88k}{8}
3200=11k
k=\frac{3200}{11}
Rewriting the equation and replacing the value of k,
A=\frac{3200t}{11n}
When t=92 and n=12
The A= \frac{3200*92}{11*12}
A=\frac{294400}{132}
A= 2231

Writing the domain in words: negative infinity to three halves and three halves to infinity

So, Option A is correct.

Step-by-step explanation:

We need to find domain of the function: f(x)=\frac{x-5}{2x-3}

<u>Domain:</u>

The domain of function is defined as all the input values for which the function is defined.

In other words we can say that any value of x that makes the denominator zero is not considered as domain of function.

In the function given: f(x)=\frac{x-5}{2x-3}

if x= 3/2 then the denominator will be zero and the function will not be defined.

So, value of x should be x>3/2 or x<3/2

We can write domain as: (-∞,3/2)(3/2,∞)

3/2 can be written as three halves.

Writing the domain in words: negative infinity to three halves and three halves to infinity

So, Option A is correct.

What is the point slope form of the line with slope −37 that passes through the point (5, 8) ?
Nonamiya [84]

The equation for point slope form is written as :

y - y1 =m(x-x1)

M is the slope which is given as -37

The given point would be X1 and y1, where X1 is 5 and y1 is 8.

The equation becomes:

y - 8 = -37(x -5)
