Answer:
10 feet 6 inch
Step-by-step explanation:
3 times 42 is 126. 126 to feet is 10 ft 6 inch
The answer should be (C):y=(-3/7)x+3 because:
if you use the slope formula: (Y2-Y1)/(X2-X1) it would look like this:
(0-3)/(7-0) and the slope of the line would be -3/7
then using the slope you just found, plug it into the y=mx+b equation along with one set of coordinates to find b (the y-intercept):
y=mx+b
0=(-3/7)(7)+b
b=3
SO, overall if you put the slope (m) and the y-intercept (b) that you found together, you get the line formula of y=(-3/7)+3
12 boys. 7 * 3 is 21. 21 girls. 4*3 is 12. 12 boys 21 girls
