Answer: B)

Step-by-step explanation:

If y = z then replace z for y in the second equation.

2 y + z = 12

2y + y = 12

3y = 12

y = 4

This also means z = 4.

Insert both of these values into the first equation:

x + y + z = 8 + 2sqr3

x + 4 + 4 = 8 + 2sqr3

x + 8 = 8 + 2sqr3

x = 2sqr3

Diego was asked to plot these points: (-50, 0), (150, 100), (200, -100), (350, 50), (-250, 0). What interval could he use for ea

ivolga24 [154]

Answer:

Interval of 50 on both axis

Step-by-step explanation:

Given

$(x_1,y_1) = (-50,0)$

$(x_2,y_2) = (150,100)$

$(x_3,y_3) = (200,-100)$

$(x_4,y_4) = (350,50)$

$(x_5,y_5) = (-250,0)$

There are several ways to do this, but I will use the observation method, since the dataset is small.

Considering the x-coordinates

$x = \{-50,150,200,350,-250}$

Each element of the data set is a multiple of 50.

Hence, an interval of 50 can be used on the x-axis

Considering the y-coordinates

$y = \{0,100,-100,50,0\}$

Each element of the data set is a multiple of 50.

Hence, an interval of 50 can be used on the y-axis

<em>So, an interval of 50 can be used on both axes</em>

Problem
After five years of earning interest at an annual rate of 3%, an investment has earned $950 in interest. To the nearest whole dollar, determine the amount of the initial investment.

Result
The initial investment was $6,333.

Solution
P = I/ i · t
P = 950/ 0.03 · 5
P = 6,333.333
