So we have the equation:

Then we need to multiply by 4 on both sides to get rid of the denominator on the left:

Then we subtract 9 on both sides to solve for z:

Therefore the answer is z = -0.6.
Answer:
B
Step-by-step explanation:
The initial value for a function is the value of y when x=0. For function A, we can see from the table that when x = 0, we have y = 4. For function B, we plug in 0 in our equation and solve: y = 3(0) + 5, or y = 5. So, because function B has a larger value of y when x = 0, function B has the greater initial value because the initial value for Function A is 4 and the initial value for function B is 5.
1/2 / 4
which can be rewritten as 1/2 * 1/4 (i bet you learnt how to divide fractions ... if you didnt then comment and ill tell you the rules for dividing)
1/2 * 1/4 = 1/8
Answer:
is equivalent to 24m-28
Step-by-step explanation:
The distributive property enables us get rid of parentheses by multiplying the term outside by each of the term inside; a bit like algebraic expansion
It states that:

Therefore 
Thus 24m-28 is the equivalent expression
Answer:
B
Step-by-step explanation:
given the first 3 terms of the geometric sequence - 4, 20, - 100
with r =
=
= - 5
the n th term formula ( explicit formula ) is
=

here r = - 5 and
= - 4, hence
= - 4
with n ≥ 1
