Split the second term in 4x^2 + 17x - 15 into two terms
4x^2 + 20x - 3x - 15
Factor out the common terms in the first two terms, then in the last two terms.
4x(x + 5) -3(x + 5)
Factor out the common term x + 5
<u>(x + 5)(4x - 3)</u>
I think (Keep) because if there’s a negative number you must flip the inequality sign hope these help have a nice day:)!
If I understand ur question, u r looking for a solution set with no solutions.
- 2m + 5 = - 2m - 5
-2m + 2m = -5 - 5
0 = -10 (incorrect...no solution)
u want the answer to be unequal with no variables. U do not want the answers to be equal, such as 0 = 0 or 10 = 10...because that would indicate infinite solutions. And u do not want the answer to contain a variable, because that would indicate 1 solution.
Answer:
D.
Step-by-step explanation:
r = 3
a1 = 2
Our explicit formula is an = a1 (r)^(n-1)
Simply plug in the terms
an = 2(3)^(n-1)

Answer:
x = 2
Step-by-step explanation:
Using the scale factor, we have ...
x/8 = 0.25/1
x = 8(0.25) . . . . multiply by 8
x = 2

<em>Additional comment</em>
I like to write proportions with the variable in the numerator. That way they are easily solved by a single multiplication. The trick is to get corresponding parts in the same positions. Here, the fractions are written ...
B/A = smaller part / larger part = x/8 = 0.25/1
