Y=mx+b
m=slope=-5
b=yintercept=7
y=mx+b
y=-5x+7
Answer:
Step-by-step explanation:
So we have the expression:
For both the numerator and the denominator, factor out a 5:
The term in the numerator can be factored. This is the difference of two squares pattern:
Both layers have a 5(x+2). Cancel them, Since we know that x <em>cannot</em> be -2, we can safely do so:
And we're done!
Notes:
If we weren't told that x ≠ -2, then we cannot divide them because if x <em>did</em> equal -2, the equation would be undefined. However, since we were given that, we can simplify.
However, even if we weren't given x ≠ -2, we can <em>still</em> simplify, but we need to add the restraint ourselves. This must be done, or else the equation won't be correct.
Answer: I think you somehow managed to try to make an answer and then accidentally clicked "add a question" and then just so happened to not realize, so you made your answer as a question...
Step-by-step explanation:
Kidding, but I'm not sure what this is supposed to be answering... There is not much context given lol.
Answer:
Step-by-step explanation:
R means Rosa
given:
R+b+c=36
R R c-2=b, (R+2)+2=c
b-2=R, R+2=b
.
R+b+c=36 substitute for b and c
R+(R+2)+((R+2)+2)=36 add like terms
3R+6=36 subtract 6
3R=30 divide by 3
R=10
.
check
R=10
b=12
c=14
10+12+14=36
36=36
Answer:
8th term is 3980.
Step-by-step explanation:
0 12 72 240 598 1250 2322
Differences in successive terms
are:
12 60 168 358 652 1072
48 108 190 294 420
60 82 104 126
22 22 22
So calculating the 8th term , working from the last line to the first:
126 + 22 = 148
148 + 420 = 568
1072 + 568 = 1658
Finally the 8th number = 2322 + 1658 = 3980
