Answer: -2.

Here’s how you solve questions like these:

First of all, you have to learn the rule on the number line.

if it’s an addition problem, go forward.

if it’s a subtraction problem, go backwards.

if the number is positive, turn to the right.

if the number is negative, turn to the left.

So pretend you’re in between a number line that goes from -10 to 10, or on 0.

< -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 >

Take the first number and look at the rule. Since 2 is positive, you start at that number and face to the right.

< -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 >
>
Next, you take the symbol in between the two numbers. Since it’s the minus sign, or a subtraction problem, you have to get ready to walk backwards But before you do that, check the last number. Since 4 is positive, you still have to face to the right and move 4 spaces backwards.

< -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 >
< < < <

If this is confusing, I’ll demonstrate it in the comments again.

Please help! Given the function problem
dedylja [7]

Answer:

B

Step-by-step explanation:

So we have the function:

f(x)=\frac{9}{5}x+32

To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:

x=\frac{9}{5}f^{-1}(x)+32

Subtract 32 from both sides:

x-32=\frac{9}{5}f^{-1}(x)

Multiply both sides by 5/9. The right side will cancel. Thus:

f^{-1}(x)=\frac{5}{9}(x-32)

Our answer is B.

And we're done!

4 less than a number n is - 15 as a equation
Nikitich [7]

Answer:

I believe the equation would be n - 2 = -15.

Step-by-step explanation:

"4 less than a number (n)" is subtraction. You can write it as "n minus 4". "is -15" means this is the difference. This can also be written as "equals -15".

n - 4 = -15

Hope this helps,

HELP HELP HELP Find X for the log function!<br><br> Please include the steps
Keith_Richards [23]

Answer: yield x

Step-by-step explanation: Definition. The logarithm is denoted "logb x" (pronounced as "the logarithm of x to base b" or "the base-b logarithm of x" or (most commonly) "the log, base b, of x"). In the equation y = logb x, the value y is the answer to the question "To what power must b be raised, in order to yield x?".
