Miranda earned $c for working 8 hours. Write an expression to show how much Miranda earned for each hour she worked.

1 answer:

3 0

$c/8
You would substitute the c for the pay per hours and follow the expression through to determine each hour's pay, but since it's not asking for an equation, you don't need to add =(amount) to the end

Answer:

x ∈ (-∞ , -2) ∪ (1, 3)

Step-by-step explanation:

The expression is already factored. Note that for the polynomial that appears in the numerator $(x-3)(x + 2)$ there are 2 roots:

$x = 3\\x = -2$

For the polynomial that appears in the denominator there is 1 root:

$x = 1$

Note that $x = 1$ does not belong to the domain of f(x) because it zeroes the denominator of the function and the division between zero is not defined.

With these three roots we do the study of signs to find out when $f(x)$

Observe the attached image

Note that:

$(x-3)$ when $x$

$(x + 2)$ when $x$

$(x-1)$ when $x$

Finally, we have the solution:

x ∈ (-∞ , -2) ∪ (1, 3)

Which equation represents a line that has a slope of -1/2 and passes through point (4, –5)?

Wewaii [24]

Y=-1/2x-3

You can rewrite the equation “y=mx+b” and fill in what you know. So your equation would look like y=-1/2x+b when filling in what you know. Now you can take the (x,y) coordinates that you were given and plug them into the equation and solve for b. So now it would be -5=-1/2(4)+b

Help please ASAP!!!!

Semenov [28]

The answer would be 65.9%. Add both paper numbers together (26.5+51.3) which is to 77.8.. to find paper not recycled just put 51.3/77.8 which would be 0.659 as a decimal.. move the decimal over to the right twice and that'd be your percentage.
