19. Which graph best represents the solution set of -4x s 6y - 54?
Answer:
I believe the answer is A and I'm sorry if I'm wrong
graph best represents the solution set of -4x <- 6y - 54 graph C. Option C is the correct option.
graph best represents the solution set of -4x < -6y - 54.
Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Since the Question seems to be incomplete, The Correct inequality in the question could be -4x < -6y - 54.
Here, graph C represents the inequality. Because y-intercept is y = -9
and the x-intercept for the inequality is x = 13.5. And it's below shaded and no boundary element can be included because of < sign.
Thus, the graph best represents the solution set of -4x < -6y - 54 graph C. Option C is the correct option.

Answer the following algebraic equation:
3x-5+9(72/8)+4=2(4x-6)
Point Value- 20 points
Answer:
X=18.4
Step-by-step explanation:
3x-5+9(72/8)+4=2(4x-6)
3x-5+9(9)+4=2(4x-6)
3x-5+81+4=8x-12
3x-5+85=8x-12
3x+80=8x-12
3x-8x=-12-80
-5x=-92
x=-92/-5
x=18.4
Checking our work:
3(18.4)-5+9(72/8)+4=2(4(18.4)-6)
55.2-5+9(9)+4=2(73.6-6)
55.2-5+81+4=2(67.6)
50.2+85=135.2
135.2=135.2

[tex]y+1 = \frac{8}{9}(x+4)[/tex]
Step-by-step explanation:
Point-slope form of an equation is given by:
[tex]y-y_1= m(x-x_1)[/tex]
Here m is the slope of the line and (x1,y1) is the point from which the line passes
Given points are:
(-4,-1) and( 5,7)
Slope is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m=\frac{7-(-1)}{5-(-4)}\\m = \frac{7+1}{5+4}\\m = \frac{8}{9}[/tex]
Now we will put the first point and slope in general form of equation of line
[tex]y-(-1) = \frac{8}{9}(x-(-4))\\y+1 = \frac{8}{9}(x+4)[/tex]
Hence,
The correct answer is: Option 2
[tex]y+1 = \frac{8}{9}(x+4)[/tex]

Step-by-step explanation:
We need to find the distance as instructed.
Its formula is:
[tex]d = \sqrt{(x_2 - x_1) ^{2} + (y_2 - y_1)^{2} } [/tex]
Let's plug in according to the formula and solve.

For every `8` boys wearing neon blue, there are `2` girls wearing neon blue. If there are `32` boys wearing neon blue, how many girls are wearing neon blue?
Answer:
8:2
32:8
Step-by-step explanation:
It's pretty simple:
If there's 32 boys, which is 4 times the amount you start with, you have to apply that to the number of girls as well since for every 8 boys, there is 2 girls.
8x4
2x4
32:8 Hope this helps
Answer:
8 girls are wearing neon blue.
Step-by-step explanation:
There are several ways to do this but one of them is to find how many groups of 8 boys are in 32. To do this we divide 32 by 8 which equals 4. We then multiply 2 by 4 which is 8.

A college has a financial aid formula that applies to applicants whose family's income is below a certain threshold. The financial aid can be determined by the function f(x)=15000+3000x, where x is the number of siblings (including half siblings and step siblings) that the applicant has living in their household. Find and interpret the given function values and determine an appropriate domain for the function.
PLZ HELP!
Answer:
This equation shows you how financial aid increases $3000 for every additional sibling, starting at $15,000.
Step-by-step explanation:
This equation means that for every sibling there is an additional $3000 in financial aid. When there are no siblings there is an automatic $15000 in financial aid.
Since you can't have "negative number" of siblings, the domain must begin with 0. You can have a lot of siblings, so let's put the end of domain as infinity.
Domain = [0, ∞)
If you substitute in this domain into the equation, the range will be the output. The least will be $15,000 and the most will be infinity as well.
Range = [15000, ∞)

The angle of elevation from a point on level ground to the top of a 50-ft tree is 25". How much closer to the tree does a point on the ground need to be for the measure of the angle of elevation to be twice the measure of the original angle? Round to the nearest tenth

In this problem, we're dealing with tan since we're working with the opposite and adjacent sides.
Remember SOH CAH TOA which means
Sin: Opposite over Hypotenuse,
Cos: Adjacent over Hypotenuse,
and Tan: Opposite over Adjacent
to remember what sin cos and tan means
So to set up a tan equation we have to do
tan(angle) = opposite side length/adjacent side length
The first equation is tan(25) = 50/x
because we have to find the length of the adjacent side so we can find how far away the tree is.
which is about 107.2 ft
The second equation is tan(50) = 50/x
because now we have to find how far away the tree is once the angle of elevation is twice the measure of the original angle (which is 50)
which is about 41.9 ft
After we subtract the two values, you get 65.3 so the answer is A.
I hope this helps!
Two make the angle from the top of the tree to the ground distance should be 41.95 ft.
What is the right-angle triangle?A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.
Given, The angle of elevation from a point on level ground to the top of a 50-ft tree is 25".
Since it makes a right-angle triangle with the tree that has a height of 50
Also given, At another angle from the ground that is twice the previous angle calculate the base.
Thus, the new angle will be 50°
thus, the base of the triangle:
Since. tan α = height/ base
in our case, α is 50°
height = 50 ft
tan α = 50 / base
base = 50/tan 50°
Base = 41.95 ft
therefore, Two make the angle from the top of the tree to the ground distance should be 41.95 ft.

The sum of two numbers is 8. When four times the smaller
number is added to two times the larger number, the result
is 18. What is the larger number?
7
6
5
4
Answer:
x+x=8
that's mean: 2.x/4 + 4.x/1 = 18/1
we find at least a common multiple of 4 and multiply the units by 4
2x + 16x = 72
18x = 72/:18
x = 4
Answer: 7
suppose: the smaller number is a
the larger number is b
because The sum of two numbers is 8 => a + b = 8 (1)
four times the smaller number is added to two times the larger number, the result is 18 => 4a + 2b = 18 (2)
(1)(2) => a + b = 8
4a + 2b = 18
<=> a = 1
b = 7
=> the larger number is 7
