Answer:
B. (-2,-4)
Explanation
Given equations:
y = 3x + 2
y = -2x - 8
Solving both equations will yield the values of x and y;
Solution:
y = 3x + 2 ----- (i)
y = -2x - 8 ------ (ii)
Using substitution method, input equation i, into ii
3x + 2 = -2x - 8
Collect like terms and solve;
3x + 2x = -8 -2
5x = -10
x = -2
Then put x = -2 into i, to find y
y = (-2 x 3) + 2
y = -6 + 2 = -4
So, the solution of the equation is B. (-2,-4)
On the computer? You write mixed fractions like: 1 2/4
Obviously, 1 2/4 is an example.

Whatever number is the exponent if negative just move it to the right how much the number is. if it 5 with an exponent of -3 then you just move the decimal point 3 times to the right. The anwer to that question would be .005
You would divide the rate
