It is T(n) = n2 - 2n + 6
Subtract 21 from both sides. If that's + 4t, the answer is (t - 3)(t + 7) and t = 3, -7 If that's - 4t, the answer is (t + 3)(t - 7) and t = -3, 7
2t-6=3-t 3t-6=3 Add t to both sides 3t=9 Add 6 to both sides t=3 Divide both sides by 3
a fraction bar is the horizontal line in a fraction ex: a/b t/r 1/3 2/4 3/5 4/6 5/7 6/8 7/9 8/1 r _ s
The two possible answer are (-7, -6) and (6, 7).
x4 + x2 - 42 Let x2 = t, so that x4 = t2 t2 + t - 42 since -42 = 7(-6) and 7 + (-6) = 1, then t2 + t - 42 = (t - 6)(t + 7) = (x2 - 6)(x2 + 7) By replacing t with x2. So we have, x4 + x2 - 42 = (x2 - 6)(x2 + 7) = [x2 - (square root of 6)2](x2 + 7) = (x - sq. root of 6 )(x + sq. root of 6)(x2 + 7)
13-6=7
means it is 6(1.042)=t+7. so in this equation we have to find the value of t. we just take '7' in opposite side of equal to side. so that t=6*1.042-7 because we know in general that if there is no sign then there is a multiplication.
6t + 7 when t = -3 is 6*(-3) + 7 = -18 + 7 = -11
6-7 tons
You would write 7x7x7x7x7x7 as 7^6 (the ^ means to the power of, 7^6 is the same as 76. You would do this because there are 6 sevens there, and 7^6 means 7 times t times 7 times 7 times 7 times 7.
8. To solve this problem, plug the given t value into the equation. So, given the equation 7t-6 and that t=2, I get 7(2) - 6. This is the same as 14-6, which is 8
2t-3-3 = 7 2t = 7+6 2t = 13 t = 6.5
acquit, piquant
The quotient of 6 and t is 6 over t, or 6 divided by t, depending on what t is. ( 6/t )
7 x 4 t 1
19-2t = 7 -2t = 7-19 -2t = -12 t = 6
