Marhall made 9 ales this week, earning a base of $186 plus $15 per ale. Vickie earned a base of $48 plus $18 per ale. Since both of them earned the same amount, we can set up the equations
Marhall made 9 ales this week.
Step by explanation
We can use an equation to solve this problem.
Let x = number of ales Marhall made
Marhall's Earnings = 186 + (15 x)
Vickie's Earnings = 48 + (18 x)
Since both of them earned the same amount, we can set up the equations and solve for x:
186 + (15 x) = 48 + (18 x)
15x = 138
x = 9
Therefore, Marhall made 9 ales this week.
Marhall made 9 ales this week, earning a base of $186 plus $15 per ale. Vickie earned a base of $48 plus $18 per ale.

The polynomial function f(x) is represented by the graph.
From the graph, the polynomial function decreases at (-2, 2)
The absolute function is given as;
f(x) = =5|x + 1| + 10
The vertex of the above function is
Vertex = (-1, 10)
Because a is negative (a= -5), the vertex is a maximum.
This means that the function decreases at (-1, ∞)
So, we have
(-2, 2) and (-1, ∞)
Combine both intervals
(-1, 2)
This means that both functions decrease at (-1, 2)

A container is the shape of an inverted right circular cone has a radius of 4.00 inches at the top and a height of 5.00 inches. At the instant when the water in the container is 2.00 inches deep, the surface level is falling at the rate of -2.00 in./s. Find the rate at which water is being drained.
The rate at which the water from the container is being drained is 24 inches per second.
Given radius of right circular cone 4 inches .height being 5 inches, height of water is 2 inches and rate at which surface area is falling is 2 inches per second.
Looking at the image we can use similar triangle propert to derive the relationship:
r/R=h/H
where dh/dt=2.
Thus r/5=2/5
r=2 inches
Now from r/R=h/H
we have to write with initial values of cone and differentiate:
r/5=h/5
5r=5h
differentiating with respect to t
5 dr/dt=5 dh/dt
dh/dt is given as 2
5 dr/dt=5*-2
dr/dt=-2
Volume of cone is 1/3 π[tex]r^{2} h[/tex]
We can find the rate at which the water is to be drained by using partial differentiation on the volume equation.
Thus
dv/dt=1/3 π(2rh*dr/dt)+([tex]r^{2}[/tex]*dh/dt)
Putting the values which are given and calculated we get
dv/dt=1/3π(2*2*2*2)+(4*2)
=1/3*3.14*(16+8)
=3.14*24/3.14
=24 inches per second
Hence the rate at which the water is drained from the container is 24 inches per second.

Which of the following steps would you perform to the system of equations
below so that the equations have opposite y-coefficients?
4x+2y = 4
12X - Y = 26
A. Divide both sides of the top equation by 3
•
B. Divide both sides of the bottom equation by 3
• C. Multiply both sides of the bottom equation by 2
• D. Multiply both sides of the top equation by 2
Answer: Choice C
Multiply both sides of the bottom equation by 2
Reason:
The y coefficient of the first equation is 2. For the other equation, that y coefficient is -1. We need these coefficients to be equal but opposite. One way to do this is to double everything in the bottom equation
The bottom equation 12x-y = 26 doubles to 24x - 2y = 52
At this point we have the equivalent system of
[tex]\begin{cases}4x+2y = 4\\24x-2y = 52\end{cases}[/tex]
And we can see that we have equal but opposite y coefficients (2 and -2). The y terms add to 0 since 2y + (-2y) = 0y = 0 meaning we've eliminated y.

Answer:
10 just find the difference between the two
Step-by-step explanation:
16-6=10
Wangmo have 6 years of teaching experience.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Let Wangmo has x years of experience.
Jigsel has 6 more years of teaching experience than Wangmo.
So, Jigsel has x + 6 years of experience.
According to the question,
the two of them have 16 years of teaching experience altogether.
That means,
we have the equation,
(x+6) + x = 16
