So we see it times 7 each time
starting with -1
geometric
an=a1(r)^(n-1)
a1=first term
r=common ratio
first term is -1
r=7
is the formula
also can look like this:
Answer:
53
Step-by-step explanation:
65x- 12 = 43x + 10
65x - 43x = 10 + 12
22x = 22
x = 22/22
<u>x = 1 </u>
(65x- 12) =
65 * 1 - 12 =<u> 53</u>
43x + 10
43 * 1 -12 = <u>53</u>
Answer:
lesser x = -4
greater x = 1
Step-by-step explanation:
here's the solution :-
=》
=》
=》
=》
now, there are two cases
case 1) where x + 4 = 0
=》x = -4
case 2) where x - 1 = 0
=》x = 1
Not exactly correct.
y=mx+b Slope is m and y intercept is b.
So, here count the units for the slope. it goes barley to the 7th box. Now, count the units for the y intercept. It goes to the fourth box.
Thus, your equation is y=7x+4
