Assuming that your equation is <span>y= (-1/4)x +2, then the slope of a line perpendicular to this one will be +4.
Thus, y = mx + b becomes 3 = 4(-4) + b, or 19 = b. Then y = 4x + 19 (ans)</span>
1) 50*50, our 2500
2) 1500
3)1500
4) 900
just multiply t the number of people by the amount each pays
The speed of the airplane = 2951 / 6.5 = 454 mph
Step-by-step explanation:
1. a) q=4+0.8(7)
q=4+5.6
q=9.6
b) q=4+0.8(100)
q=4+80
q= 84
2. a) 12=4+0.8p
-4 -4
<u>8</u>=<u>0.8p</u>
0.8 0.8
10=p
b) 60=4+0.8p
-4 -4
<u>56</u>=<u>0.8p</u>
0.8 0.8
70=p
Answer: True because every 10 millimeters are equal to 1 centimeter
So, that as well means 1 millimeter is equal to .1 centimeter
