To make t the subject is basically isolating t
S = at + bt
We see on the right side that t is common, so we factor it out.
S = t(a + b)
Divide by (a+b) to isolate t
a + b and a + b cancels out
We are left with the answer:
t = 
Answer:
1/2
Step-by-step explanation:
trust me because to find slope make y 1 so 1÷2=1/2
K = (x + 1) (x + 2) /3x + 7
Hello from MrBillDoesMath!
Discussion:
The slope of the tangent to the curve y = 4x^3 is given by the first derivative.
-----------------------------------
y' = 4 (3x^2) = 12x^2
At (-3,-108), the slope is 12x^2 = 12(-3)^2 = 12*9 = 108
-----------------------------------
-----------------------------------
y = mx + b
From the first part, m = 108 so y = 108x + b.
Substituting y = -108 when x = -3 gives
-108 = 108(-3) + b => add 3* 108 to both sides
-108 + 108(3) = b => as 3 -1 = 2
108*2 = b = 216
y = 108x + 216
-----------------------------------
Thank you,

Answer: B
Step-by-step explanation:
The question asks for [n≥-5] to be true, which means any value that is greater or equal to -5 will be considered.
A. {-5, -5.5, -6}
-5 TRUE
-5.5 FALSE
-6 FALSE
B. {-5, -4.5, -3}
-5 TRUE
-4.5 TRUE
-3 TRUE
C. {-6, 0, 5}
-6 FALSE
0 TRUE
5 TRUE
D. {-6, -7, -8}
-6 FALSE
-7 FALSE
-8 FALSE
As shown above, we can clearly see that Set B is the set that makes the inequality true.
