Answer= 6.5y+12

distribute the 5 in the parentheses:
(-6y-3) + (15+12.5y)
(you can take away the parentheses after this step)

then add like terms together.
12.5y + (-6y) = 6.5y
15 + (-3) = 12

make it one expression.
6.5y + 12

Simplify and state the domain for x^2-x-12/x-4

saw5 [17]

The domain of a function is the set of input values the function can take

The domain is all set of real numbers

<h3>How to determine the domain</h3>

The expression is given as:

$\frac{x^2 - x - 12}{x - 4}$

Factorize the numerator of the expression

$\frac{(x - 4)(x + 3)}{x - 4}$

Simplify: Cancel out the common terms

$x + 3$

The above expression can take any value of x.

Hence, the domain is all set of real numbers

2) Which of the following represents an equation of a line parallel to one whose equation is 2y + 8x = 18?

Reika [66]

Parallel has the same slope
2y + 8x = 18
Make it slope in form: y = mx + b
Divide the equation by 2
y + 4x = 9
Now subtract 4x
Y = -4x + 9
The slope is -4
Which equation also has same slope?

Solution: A

A statue is mounted on top of a 42 foot hill. From the base of the hill to where you are standing is 73 feet and the statue subt

larisa [96]

Answer:

19.72 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation between angles and sides of a right triangle:

Tan = Opposite/Adjacent

Then the relations in the attached drawing are ...

tan(α) = 42/73

tan(α +10.3°) = (42 +SH)/73

Solving the first equation for α, we get ...

α = arctan(42/73)

Solving the second equation for SH, we get ...

73 tan(α +10.3°) = 42 +SH

SH = 73·tan(arctan(42/73) +10.3°) -42 = 73·tan(29.91°+10.3°) -42

SH = 73·0.84547 -42 = 19.720 . . . . feet

The height of the statue is about 19.72 feet.

Let f(x)= 8x³ + 16x² -15 and g(x) = 2x+1. f(x)/g(x).

N76 [4]

Answer:

f(x)/g(x) = 4x^2+6x-3 remainder -12

f(x)/g(x) = (4x^2+6x-3)/(2x+1) + (-12)/(2x+1)

((4x²+6x-3)-12)/(2x+1)

Step-by-step explanation:

f(x)= 8x³ + 16x² -15

g(x) = 2x+1.

Using long division,

f(x)/g(x) = 4x^2+6x-3 remainder -12
