Answer:

Option A, -15

Step-by-step explanation:

Step 1: Look at the function that needs to be outputted when x = -3

Since x = -3, that means it falls into the first category of x ≤ -3

Step 2: Carry out the instructions

The function for the first category is $-x^{2} + 2x$

$f(-3) =-(-3)^{2}+2(-3)$

$f(-3) = -(9) - 6$

$f(-3) = -15$

Answer: Option A, -15

2) Lisa is ordering sand from the Internet, On one site she found sand on sale for

Anastasy [175]

For this case we must find the unit cost (dollars per pound) of each site and then compare.

We take into account that:

1kg equals 2.205 pounds

So, we have:

Site 1:

$C = 2.25 \frac {dollars} {pound}$

Site 2:

$5kg = 5 (2.205\ pounds) = 11.025 pounds$

So, the unit cost is:

$C = \frac {14} {11.025} \frac {dollars} {pound} = 1.27 \frac {dollars} {pound}$

Thus, the best deal is on site 2.

Which function is equivalent to the inverse of y=sec(x)

kipiarov [429]

From the identity:

$sec(x)= \frac{1}{cos(x)}$

$f(x)=sec(x)= \frac{1}{cos(x)}$

the inverse of f is g such that f(g(x))=x,

we must find g(x), such that $\frac{1}{cos[g(x)]}=x$

thus, $cos[g(x)]= \frac{1}{x}$

$g(x)=cos^{-1} (\frac{1}{x})$

Answer: b. g(x)=cos^-1(1/x)

Please help, this is for 8th grade math.

expeople1 [14]

Answer:

(2,-2)

Step-by-step explanation:

The first step is to substitute y in the first equation with the right side of the second equation because they both equal to y.

-3x+4 = 4x-10

-3x-4x+4-4 = 4x-4x-10-4

-7x = -14

-7x/-7 = -14/-7

x = 2

Plugin 2 for x for either equation to solve for y, I'll be using the second equation, but either one is fine.

y = 4(2)-10

y = 8-10

y = -2

Plugin x = 2 and y = -2 into (x,y), and you get (2,-2)
