What is f(-2) for the function f(x)= -3x + 8
NISA [10]

Answer:

f(-2)=14

Step-by-step explanation:

Given function:

f(x)=-3x+8

To find f(-2)

For the given linear function the x value represents the input values of the function or the domain of the function while f(x) represents the output values or the range of the function and is often refereed to as the y values of the function.

In order to find f(-2) we will plugin -2 in place of x in the function and evaluate it. It means our input value =-2 and we need to calculate the output value.

Thus,

f(-2)=-3(-2)+8

f(-2)=6+8    [ Product of two negative numbers is a positive number]

∴ f(-2)=14 (Answer)

Helppp easy math please !!!!!
nevsk [136]

Answer:

x = -4       x = 3

Step-by-step explanation:

To find the x intercepts, set y =0

(x+4) (-x+3) =0

Using the zero product property

x+4 =0    -x+3 =0

x = -4       x = 3

-7 2/3 + (-5 1/2) +8 3/4
Vika [28.1K]

Answer:

-4\frac{5}{12}

Step-by-step explanation:

Here we have three terms, none with matching denominators.

Now we have to find the least common multiple of 3, 2, and 4. We can ignore the 2 here because the 4 takes care of that. The least common multiple of 3 and 4 is 12. 12 is also divisible by 2, so we've fulfilled those terms.

Now, let's get to work. We have to convert all of those mixed numbers into fractions with a denominator of 12. I'll skip the explanation and just do the work step by step. Ask questions if you are unsure of something.

First, we'll just put them all in a row.

-7\frac{2}{3} -5\frac{1}{2} +8\frac{3}{4}

Next, I'm going to put them in the forms of improper fractions, just to make this a bit less cluttered.

-\frac{23}{3} -\frac{11}{2} +\frac{35}{4}

Then, I'll adjust the denominators of the fractions by multiplying the whole fraction by whatever it takes to make that denominator 12. Remember, multiply the numerator and the denominator by the same number.

-\frac{23}{3}(\frac{4}{4})-\frac{11}{2}(\frac{6}{6})+\frac{35}{4}(\frac{3}{3})

-\frac{92}{12} -\frac{66}{12} +\frac{105}{12}

Now, let's add them together.

-\frac{53}{12}

You can leave this as an improper fraction, but I'm going to put this into mixed number form for you.

-4\frac{5}{12}
