0.4(−0.45)=9.2
2(−0.45)5=9.2
Step-by-step explanation:
=23.45
Answer:
a₇ = 2.375
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r = 
= 
= 
= - 
This indicates the sequence is geometric with nth term
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 152 and r = - , then
= 152 
, so
a₇ = 152 
= 152 × 
= 2.375
Answer:
A
Step-by-step explanation:
Think about the square root of 64, which is 8. It will only be slightly higher than 8, which will not even be .5, so 8 is the closest number.
Answer:
y = 2x - 5
Step-by-step explanation:
y-intercept form is y = mx + b, where m is the slope and b is the y-intercept. We know the slope is 2, so all that's left is to find the y-intercept. To do this, for every 1 we subtract from x in (4,3), we take away 2 from y because the slope is two. We keep doing this until x is zero. The remaining y-value is the y-intercept.
Answer:
Infinite solutions.
Step-by-step explanation:
If an equation is an identity, then there will be infinite solutions that the identity will have.
Let, us assume that an identity equation is given by
(a + b)² = a² +2ab + b².......... (1)
Now, putting any real values of a and b the identity will be satisfied.
Therefore, there are infinite solutions for an identity equation. (Answer)
