Answer:
A
Step-by-step explanation:
4(0.5x+2.5y-0.7x-1.3y+4)
=2x+10y-2.8x-5.2y+16
=-0.8x+4.8y+16
hope this helps :)
Answer:
X=2.5
Step-by-step explanation:
3x - 5 = 1/2x + 2x
3x - 1/2x - 2x = 5
1/2x = 5
X = 5 ÷ 1/2
X = 2.5
The value of m must be 4 and the value of b must NOT be -3.
No matter what numbers they involve, two equations with the SAME slope (m) and a DIFFERENT y-intercept (b) have no solution. This is because they form parallel lines, never crossing and therefore never giving a solution.
