Answer:
Graph B is the answer.
Step-by-step explanation:
We know that both functions are inequalities, however,
The second one (red on the graph) has 'less or equal sign, ≤' meaning that, the line of the function is included as shown on graph B with a continuous line.
The first one has a 'greater than, >' meaning that the line of the function is not included, therefore the line is a dotted line, as shown on graph B.
The shaded area must be between the two inequalities because that where the X's can be met.
Therefore, the answer is graph B.

A nontoxic furniture polish can be made by combining vinegar and olive oil. the amount of oil should be five times the amount of vinegar. how much of each ingredient is needed in order to make 39 oz of furniture polish?
Final answer:
To make 39 oz of non-toxic furniture polish with the ratio of olive oil being five times the amount of vinegar, 6.5 oz of vinegar and 32.5 oz of olive oil are needed.
Explanation:
We know the oil to vinegar ratio is 5:1.
Let x be the amount of vinegar: We can use any variable to represent the unknown amount.
Set up the equation: Since the total volume is 39 oz and the ratio is 5:1, we have the equation: x (vinegar) + 5x (olive oil) = 39 oz.
Combine like terms: 6x = 39 oz.
Solve for x (vinegar): x = 39 oz / 6 = 6.50 oz.
Calculate the olive oil amount: Olive oil = 5 × vinegar = 5 × 6.50 oz = 32.50 oz.
Therefore, you'll need 6.50 oz of vinegar and 32.50 oz of olive oil to make 39 oz of furniture polish.
Remember to always test the polish on a small inconspicuous area of the furniture before applying it to the entire surface. And, for best results, use a clean, soft cloth to apply the polish and buff it to a shine.

Step-by-step explanation:
Given : Functions [tex]f(x) = 3x +1[/tex] and[tex]g(x) = x^2-6[/tex]
We have to choose the correct option from the given options that represents (f-g)(x)
Consider the given functions
[tex]f(x) = 3x +1[/tex] and[tex]g(x) = x^2-6[/tex]
then , (f - g)(x) = f(x) - g(x)
Substitute, we have,

Applying plus - minus rule[tex]-(-a)=a[/tex], we have,
[tex]f(x)-g(x)=3x+1-x^2+6[/tex]
Simplify and write in standard form, we have,
[tex]f(x)-g(x)=-x^2+3x+7[/tex]
Thus, The[tex](f-g)(x)=-x^2+3x+7[/tex]

y = mx + b Which variable represents the slope?
The variable 'm' represent the slope.
What is slope?The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Given:
y= mx + b
The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.
The net change in y coordinate is Δy, while the net change in the x coordinate is Δx.
So the change in y coordinate with respect to the change in x coordinate can be written as,
m = Δy/Δx
where, m is the slope
The slope of a line can be calculated from the equation of the line. The general slope of a line formula is given as,
y = mx + b
where,
m is the slope, such that m = tan θ = Δy/Δx
θ is the angle made by the line with the positive x-axis
Δy is the net change in y-axis
Δx is the net change in x-axis

Four times the larger of two numbers is equal to seven times the smaller. the sum of the numbers is 22. what are the numbers?
The larger is 14 the smaller is 8
Explanation:Let the larger number be L and the smaller be S
So we know that
1) L+S=22
And
2)4L=7S
From equation 1) we get L=22-S
Substitute this into equation 2) to get 4(22-S)=7S
88-4S=7S
88=11S
S=8. The smaller number is 8
As they total 22 the larger number is 14.
Check: 4x14=7x8. Yes
Solution 2:
Let x= larger number
And let y= smaller. umber
Now we are told that:
4x=7y--------eq1
We are also told that:
x + y=22-----eq2
Substitution method looks easier.
From eq1 x=(7/4)y. Substitute this into eq2
(7 /4)y +y=22
(7/4)y+(4/4)y=22
(11/4)y=22 multiply each side by 4
11y=88
y=8
From eq2, x+8=22
x=14
Hope this helps
Final answer:
To find the two numbers where four times the larger is equal to seven times the smaller, and the sum is 22, we set up a system of equations and solve them. We find that the larger number is 14 and the smaller number is 8.
Explanation:
To solve the question "Four times the larger of two numbers is equal to seven times the smaller. The sum of the numbers is 22. What are the numbers?", we use a system of equations. First, we assign variables to the unknowns: let x be the larger number and y be the smaller number. According to the problem, we have two equations:
4x = 7y (because four times the larger number is equal to seven times the smaller)
x + y = 22 (because the sum of the numbers is 22)
Now, we can solve for one of the variables. Let's isolate y in the second equation:
y = 22 - x
Substitute this expression for y into the first equation:
4x = 7(22 - x)
Expand and solve for x:
4x = 154 - 7x
11x = 154
x = 14
Then we find y by substituting x back into the equation y = 22 - x:
y = 22 - 14
y = 8
Therefore, the larger number is 14 and the smaller number is 8.

The height h, in feet, of a projectile t seconds after launch is modeled by the equation h = 32t – 16t2. how long after launch does the projectile return to the ground? 2 seconds4 seconds14 seconds16 seconds
Answer:
The correct option is A. 2 seconds
Step-by-step explanation:
The height h, in feet, of a projectile t seconds after launch is modeled by the equation h = 32·t – 16·t²
Now, we need too find the time after which the fired projectile touches the ground.
So, The fired projectile when touches the ground, The height of the projectile will become 0
⇒ Find the required time t when h = 0
⇒ 0 = 32·t - 16·t²
⇒ 0 = t × (32 - 16·t)
⇒ t = 0 or 32 - 16t = 0
⇒ 16t = 32
⇒ t = 2
So, t = 0 or t = 2
t cannot be 0 because initially the projectile is in the air as it has been already fired
⇒ t = 2 seconds
Therefore, The correct option is A. 2 seconds

What is the measure of ∠D ?
Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.
m∠D=
°
Answer:
[tex]m\angle D=29.05[/tex]
Step-by-step explanation:
We have been given an image of a right triangle and we are asked to find the measure of angle D.
We can see from our given triangle that the opposite side of angle D measures 25 ft and adjacent side of angle D is 45 ft.
Since we know that tangent represents the relation between the opposite and adjacent sides of a right triangle.
[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
Upon substituting our given values in above formula we will get,
[tex]\text{tan}\angle D=\frac{25}{45}[/tex]
[tex]\angle D=\text{tan}^{-1}(\frac{25}{45})[/tex]
[tex]\angle D=29.054604099077[/tex]
Upon rounding our answer to nearest hundredth we will get,
[tex]\angle D\approx 29.05[/tex]
Therefore,the measure of angle D is 29.05 degrees.
4. find the real number roots. sqrt-0.25
Given is square root of a negative real number, i.e. [tex] \sqrt{-0.25} [/tex]
When we find square root of positive real numbers, we get Real answers.
But when we find square root of negative real numbers, we get Imaginary answers. To solve them, we can split the given negative number into product of -1 and the number itself but with positive sign. e.g. -4 = -1 x 4.
For square root of -1, we use english letter 'i' called Imaginary unit i.e. [tex] \sqrt{-1} = i [/tex]
Now we can use -0.25 = -1 x 0.25
[tex] \sqrt{-0.25} =\sqrt{-1*0.25} \\\\
\sqrt{-0.25} =\sqrt{-1}*\sqrt{0.25} \\\\
\sqrt{-0.25} =i*0.5 \\\\
\sqrt{-0.25} =0.5i [/tex]
Hence, "0.5i" is the final answer.
The square root of -0.25 is not a real number because the square root of a negative number is not defined within the set of real numbers.
The square root of a negative number is not a real number. In the case of √(-0.25), the expression is undefined within the set of real numbers because taking the square root of a negative number results in a complex number. The square root of a negative number is typically represented using the imaginary unit "i" in the complex number system. Therefore, √(-0.25) is not a real number.
