Answer:
21
Step-by-step explanation:
The x intercept is represented by the coordinate (x,0) on x axis.
So, to find the x intercept ,we need to equate y=0 in the equation 20x+70y=420
=> 20x+ 70*0=420
=> x=420/20 =21.
x intercept is (21,0).
Answer:
twelve
Step-by-step explanation:
4 times 3= twelve
(x+2)(1-x)=-4
subtract 2 from both sides: x(1-x)=2
simplify:x-2x=2
subtract: -x=2
switch the negatives
x=-2
63= 60 then... 60/6 = 10
108=100 then... 100/ 8= 12. 5
60 sec in 1 min so ...
12.5 * 6 = 75
10*6= 60
75 - 60= 15 feet apart.
