Answer: x = -28
Step-by-Step Explanation:
3(2x + 12) = 2(2x - 10)
3 * 2x + 3 * 12 = 2 * 2x - 2 * 10
6x + 36 = 2 * 2x - 2 * 10
6x + 36 = 4x - 20
6x - 4x + 36 = -20
2x + 36 = -20
2x = -20 - 36
2x = -56
x = -56/2
=> x = -28
Therefore, x = -28
Answer: f(x) = 5x3-3x2+x
f(x) —> - ♾ as x —> - ♾
and f(x) —> ♾ as fx —> ♾
Step-by-step explanation:
We can see it is cubic polynomial with positive leading coefficient.
Degree of polynomial is 3 and leading coefficient +3
End behavior depends on two parameter degree and leading coefficient.
It would be negative infinity as x approaches to negative infinity and positive infinity as x approaches to positive infinity.
We can see in graph also. Please take a look attached graph.
Collect like terms
(8xy + 13xy) + (12x - 6x)
Simplify
<u>21xy + 6x</u>
Let’s do 3x - 8 ≤ 23 first.
You need to rearrange this so that x is on its own.
+8 to both sides
3x ≤ 31
/3 on both sides
x ≤ 31/3
Then the second, -4x + 26 ≥ 6
-26 from both sides
-4x ≥ -20
/-4 on both sides
x ≥ 5
So x is greater than or equal to 5, which can also be written as 5 ≤ x
And for the first one, x is less than or equal to 31/3, which can still be written as x ≤ 31/3, so your final answer is:
5 ≤ x ≤ 31/3
(1) -(5y - 2)= -5y+2
(2) -5 (3n + 1)= -15n - 5
(3) too long to do
