2 answers:

5 0

Plug the x and y values in and see which one equals -1.
5x + 2y = -1
A. 5(1) + 2(-3) = 5 = 6 = -1
B. 5(-1) + 2(4) = -5 + 8 = 3
C. 5(2) + 2(-4) = 10 - 8 = 2
D. 5(-2) + 2(5) = -10 + 10 = 0

The answer is A

The easiest way to do this is to plug in the numbers for the variebles and see if they equal the same in both sides. lets try the first one 5(1)+2(-3)=-1, multiply the nmbers to get 5-6=-1 now simplify to get the answer of -1=-1, they both equal the same so this means that the first option is the correct one

Hope this helps

Identify the translation of the parent function for y = |x + 8|. 8 units up 8 units right 8 units down 8 units left

padilas [110]

Hi there

The parent function is the following:
$y = |x|$

We need to translate the function 8 units left to get the function: $y = |x + 8|$

Therefore the answer is: 8 units left.

Zinaida [17]

Answer:

a) Circumference of Ferris wheel.

b) $\text{Circumference} = \pi d$

c) 628 feet

Step-by-step explanation:

We are given the following in question:

Diameter of Ferris Wheel = 200 feet

a) Distance around Ferris wheel

The distance around Ferris wheel is given by the circumference of Ferris wheel.

b) Formula to calculate circumference

$\text{Circumference} = \pi d$

where d is the diameter of he wheel.

c) Distance traveled in one rotation

This will be given by the circumference of the Ferris wheel.

$\text{Distance} = \pi d = 3.14\times 200 = 628\text{ feet}$

Thus, the distance traveled in one rotation is 628 feet.
