The system of equations is graphed on the coordinate plane.
cricket20 [7]

It would be: (x,y) = (-1,-1)

-x-2 = 3x+2

3x+x = -2-2

x = -4/4

x = -1

Put that value in 1st equation, y =  -(-1)-2 = 1-2 = -1 SOLVED

e-lub [12.9K]

Answer:

4.08%

Step-by-step explanation:

% error = error/actual length × 100

Error = 20.4-19.6

Three to the sixth power divided by three to the third power
mrs_skeptik [129]

let's first convert this to number form.

3^6 / 3^3= what?

to divide a number with the same base but different exponent, we simply subtract the second exponent by the first exponent.

3^6 / 3^3 = 3^6-3=3^3

1. Using the diagram below, answer the following question. Arthur is at the coordinate A(20,35), Cameron is at the coordinate C(
statuscvo [17]

Answer:

(42.5, 37.5)

Step-by-step explanation:

Given:

Arthur = A(20, 35)

Cameron = C(65, 40)

Jamie = J(45, 20)

Required:

Coordinate of the midpoint of the distance between A and C.

SOLUTION:

Midpoint (M) of AC, is given as:

M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})

Let A(20, 35) = (x_1, y_1)

C(65, 40) = (x_2, y_2)

Plug the values into the given formula:

M(\frac{20 + 65}{2}, \frac{35 + 40}{2})

M(\frac{85}{2}, \frac{75}{2})

M(42.5, 37.5)

Coordinate Jamie should run towards is (42.5, 37.5)
