Answer:
<em><u>=15a−8</u></em>
Step-by-step explanation:
Let's simplify step-by-step.
4(2a−1)−4+7a
Distribute:
=(4)(2a)+(4)(−1)+−4+7a
=8a+−4+−4+7a
Combine Like Terms:
=8a+−4+−4+7a
=(8a+7a)+(−4+−4)
=15a+−8
Answer:
=15a−8

Answer:
C) 7
Step-by-step explanation:
3^x−2=2187
Step 1: Add 2 to both sides.
3^x−2+2=2187+2
3^x=2189
Step 2: Solve Exponent.
3^x=2189
log(3x)=log(2189) <<Take log of both sides
x*(log(3))=log(2189)
x= log(2189)/log(3)
x=7.000832
Hello from MrBillDoesMath!
Answer:
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Discussion:
The terms are 12, 9, 6, 3 so we are apparently subtracting 3 from each succeeding term. . Hence
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Thank you,
MrB
We have been given that the number of species of coastal dune plants in Australia decreases as the latitude, in °s, increases.
Further we know that there are 34 species at 11°s and 26 species at 44°s.
We can express the given information at two ordered pairs as shown below:
Let us find slope of the line through these points:
Therefore, we can write the equation of line in slope intercept form as:
Where b is the y intercept, and we can find its value using one of the two points.
Therefore, the required equation of the linear function is:
Answer is 3a²b (a + b)
Step-by-step explanation:
- Step 1: Find 3a² (ab²+b²)
⇒ 3a² (ab²+b²) = 3a³b + 3a²b² = 3a²b (a + b)
