The number of solutions of the system of equations is 904 086
Answer:
x = 4
Step-by-step explanation:
Step 1: Write equation
-2x + 1 = -4x + 9
Step 2: Solve for <em>x</em>
- Add 4x to both sides: 2x + 1 = 9
- Subtract 1 on both sides: 2x = 8
- Divide both sides by 2: x = 4
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-2(4) + 1 = -4(4) + 9
-8 + 1 = -16 + 9
-7 = -7
Answer:
it's 88.9
Step-by-step explanation:
5 - 8x < 2x + 3
5 - 8x < 2x + 3
<u>-3 - 3 </u> Step 1.
2 - 8x < 2x
<u> +8x +8x </u> Step 2. Missing step
2 < 10x
<u>÷10 ÷10</u> Step 3.
<u>2/10 < x</u>
<u>1/5 < x
The missing step is add 8x to both sides of the inequality.</u>
To find n-therm of a geometric sequence, we are going to use the formula

where:

is the term we are looking for

is the first term

is the ratio

is the position of the number in the sequence
From the question we now that

,

, and

. Lets replace those values into our formula to get:



We can conclude that in our geometric sequence

; therefore, the answer is
A.
