Answer:
A
Step-by-step explanation:
Given
x² + 6x
To complete the square
add ( half the coefficient of the x- term )² to x² + 6x
x² + 6x + (3)²
= x² + 6x + 9

State the degree and end behavior of the following polynomial f(x)=4x^3+3x^5-x^2 - 2
Answer:
Degree
Five Degree
End Behavior
When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.
Step-by-step explanation:
[tex]y = 4 {x}^{3} + 3 {x}^{5} - {x}^{2} - 2[/tex]
A five-degree polynomial function. Rearrange the terms.
[tex]y = 3 {x}^{5} + 4 {x}^{3} - {x}^{2} - 2[/tex]
Because it is an odd-degree function, the graph increases from negative infinity and ends by increasing at positive infinity.

When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.

Answer:
A and B
Step-by-step explanation:
Basically all you have to do is combine those equations. How do you do that? You add/subtract the equations from each other, OR use substitution. It's hard to explain I recommend searching it up.
However, in this equation this is not what they are asking for. Only ONE equation has a solution when combined/substituted. Some have false solutions such as 3=0, which is not true. Some have infinite solutions where every number works.
Solving A:
This works because it actually gives us the value of y and x instead of giving us an incorrect statement.
Solving B:
This works as well!
Solving C:
This has no solution. It doesn't work and it ends up with 0 = -6, which is not true.
Solving D:
This has more than 1 solution.
Solving E:
This does not work, it has no solutions. It ends up with 0 = -2.

If f(x) = 2x, which of the following shows the graph of f(x) = 2(x) + 2?
Answer: the first graph
Step-by-step explanation:
The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The correct option is A.
What is the y-intercept of a function?The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At the y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
Given f(x)=2, therefore, the graph will have a y-intercept as 0.
But when the value of f(x) = 2(x) + 2, then the graph of the function will have the y-intercept at 2.
Hence, the correct option is A.

The answer is 6+(-4) = 2
Answer:
2
Step-by-step explanation:
it's just like saying 6-4 is two a negative is like a positiveWhile on vacation in Bloomington, Ashley went out for a dinner that cost $20. If sales tax in Bloomington is 10% and Ashley left a 15% tip on $20, what was the total cost of her meal?
Answer:
$25
Step-by-step explanation:
Given that:
Cost of Ashley's dinner in Bloomington = $20
Sales tax = 10%
Tip = 15% on $20
To find:
Total cost of the meal ?
Solution:
Let us find the sales tax first of all.
Sales tax is 10% of the total bill.
Therefore, sales tax = 10% of $20
[tex]\Rightarrow \dfrac{10}{100}\times 20\\\Rightarrow \$2[/tex]
Tip left is 15% of the total bill.
Therefore, tip = 15% of $20
[tex]\Rightarrow \dfrac{15}{100}\times 20\\\Rightarrow \$3[/tex]
Now, total cost of the meal = Food cost + Sales tax + tip
Total cost of the meal = $20 + $2 + $3 = $25
The slope is -1 and the y-intercept is -5. Write a linear equation in slope-intercept form.
Someone pls help me!
[tex]y = mx + b[/tex]
where m = slope and b = y-intercept.
We have both given slope and y-intercept. We can simply substitute the given slope and y-intercept in slope-intercept form.
SubstitutionSubstitute m = -1 and b = - 5 in the equation.

Step-by-step explanation:
Which equation represents a line which is perpendicular to the line 5x + 2y = 12?
Answer:
y = ²/₅ x - 3Step-by-step explanation:
Changing to slope-intercept form:
5x + 2y = 12 {subtract 5x from both sides}
2y = -5x + 12 {divide both sides by 2}
y = -⁵/₂ x + 6
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇔ m₁×m₂ = -1
{Two lines are perpendicular if the product of theirs slopes is equal -1}
y =-⁵/₂ x + 1 ⇒ m₁ = -⁵/₂
-⁵/₂× m₂ = -1 ⇒ m₂ = ²/₅
So, any line perpendicular to 5x + 2y = 12 must have slope m =²/₅
#1: Solve the inequality below.
-3x + 5 < -19
Explanation: Just like any of your two-step equations,
in this inequality, start by isolating the x term which in this
case is -3x by subtracting 5 from both sides.
That leaves you with -3x < -24.
To get x by itself, divide both sides by -3 but watch out.
When you multiply or divide both sides of an inequality by a
negative number, you must switch the direction of the inequality sign.
So we have x < 8 and put your final answer in
set notation and it look like this → {x: x < 8}.
