Answer:
Step-by-step explanation:
To solve this, plug 2b+1 in for a. :
4(2b+1)-5. Solve for b.
First use the distributive property:
8b+4-5=?
Combine like terms:
8b-1=?
Solve for b.
add 1 to both sides.
8b=1
Divide both sides by 8.
b=1/8
Hey there!
-x^2 - 2x + 7
To find the vertex, you will rewrite in the vertex form.
f(x) = -(x+1)^2+8
(-1,8)
Hope this helps!
Answer:
i think its -2 or 6 or -6.75, depending on how you phrase it. just use the formula below :) sorry im not much help
Step-by-step explanation:
-5-3/4-1
m=x2-x1/y2-y1
This is a geometric sequence problem.
You have a sequence of;
2/3, 2, 6, 18, 54
Their common ratio is t1/t0 = 2/(2/3) = 3
Formula for G.P n terms is denoted by
ar^(n-1) = nth term
Where;
a - first term
r - common ratio
n - nth term in the sequence
So the exponential formula is basically that.
Example
To find the 3rd term which is 6
ar^(n-1) = (2/3)(3)^(3-1)
-> (2/3)(3)²
-> (2/3)(9)
-> (2)(3)
-> 6
