Answer:
<h2>x = -2, y = 1</h2>
Step-by-step explanation:
given the system of equations y=1/2x+2 and y=-2x+-3, since the 2 equations are functions of y, we will equate both equations together and calculate the value of x as shown
1/2x+2 = -2x-3
x/2+2x = -3-2
5x/2 = -5
5x = -10
x = -10/5
x = -2
Substituting x = -2 into any of the equation to get the value of y we have;
y = -2(-2)-3
y = 4-3
y = 1
The solution to the system of equation (x, y) = (-2, 1)
Answer:
<h2><u><em>
8/3 or 2.66.. units </em></u></h2>
Step-by-step explanation:
TSA of cube = 6a²
side = 2/3
= 6 x (2/3)²
= 6 x 4/9
= 2 x 4/3
=8/3
<u>Ans = 8/3 units or 2.66.. units</u>
