Answer:
Step-by-step explanation:
Given the equation y=-2x+1 and given another equation y=mx+b in order for us to have no solution we must guarantee that both lines do not intersect. Recall that m is the slope of the second equation and b the y-intercept. To guarantee that both lines don't intersect, they must be parallel. To have this result, we must have that they have the same slope but different y intercept. That is take m = -2 and b any value different to +1. For example, the b = 6. So
y = -2x+6 = -2(x-3) is another equation that gives no solution to the system.
The GCF of 8x and 40 is 8.
Answer:
1176
Step-by-step explanation:
A room with dimensions 10 ft by 5 ft has an area of 50 ft².
A room with dimension 7 ft by 21 ft has an area of 147 ft².
Writing a proportion:
400 tiles / 50 ft² = x / 147 ft²
x = 1176 tiles
