Answer:
x = 12
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
9x + 11 + 3x - 15 + 2x + 16 = 180, simplify left side
14x + 12 = 180 ( subtract 12 from both sides )
14x = 168 ( divide both sides by 14 )
x = 12

What is the equation of the line?
Answer:
y = -7
Step-by-step explanation:
As the slope is m = 0, that means there is no slope. All values of x in the domain will always output -7. Therefore, your equation would be y = -7.
Answer:
y = -7
Step-by-step explanation:
Use the formula:
y = mx + b
Where m is the slope and b is the y-intercept.
The slope of the equation is equal to 0.
The y-intercept is at (0, -7)
y = (0)x + -7
y = -7
The equation of the line is y = -7.

The vertex of this parabola is at (4,-3). Which of the following could be its
equation?
A. x==3(y - 3)2 + 4
B. X=-3(+4)2-3
C. X=-3(-4) 2-3
D. X=-3(y + 3) - 4
Answer:
Option D.
Step-by-step explanation:
From the given graph it is clear that it is a parabola along to the x-axis.
Vertex form of a parabola along the x-axis is
[tex]x=a(y-k)^2+h[/tex]
where, (h,k) is vertex.
From the graph it is clear that the vertex of the parabola is (4,-3). So, substitute h=4 and k=-3 in the above equation.
[tex]x=a(y-(-3))^2+(4)[/tex]
[tex]x=a(y+3)^2+4[/tex] ...(1)
The graph passing through (1,-2), so substitute x=1 and y=-2 in the above equation.
[tex]1=a(-2+3)^2+4[/tex]
[tex]1-4=a(1)^2[/tex]
[tex]-3=a(1)^2[/tex]
Substitute a=-3 in equation (1).
[tex]x=-3(y+3)^2+4[/tex]
Therefore, the correct option is D.

Step-by-step explanation:
Natalia wants to attend Louisiana State University. One year at Louisiana State University costs approximately $24,000. She currently has $4,000 in savings. Natalia has received a one-time grant of $1,500 and an annual academic scholarship for $3,500. She plans to enroll in the work study program that will pay $12,000 annually for part-time work. How much will Natalia need to borrow in student loans in order to attend Louisiana State University for 4 years?
Answer:
He needs to borrow $28,500 to attend the University for 4 years.
Step-by-step explanation:
One year at the University costs $24,000. The total she has to pay are 4 * $24,000 = $96,000
minus the $4,000 she has in savings: $96,000 - $4,000 = $92,000
minus the $1,500 she received one time: $92,000 - $1,500 = $90,500
minus $3,500 per anual
4* $3,500 = $14,000
$90,500 - $14,000 = $76,500
minus $ 12,000 per anual
4 * $12,000 = $48,000
$76,500 - $48,00 = $28,500
There are 32 students in a class. They are taking either biology or chemistry or both. The
number of students taking biology is three times as many as the number of students
taking chemistry. If 4 students are taking both biology and chemistry, how many
students are in biology?
Answer:
27
Step-by-step explanation:
Let's call the number of students taking chemistry x which makes the biology students 3x. Since the overlap is 4 the amount of students who take chemistry only or biology only is x - 4 and 3x - 4 respectively therefore we can write:
x - 4 + 3x - 4 + 4 = 32
4x - 4 = 32
4x = 36
x = 9
Since x = 9, the amount of biology students is 3x which is 3 * 9 = 27.

27

Identify the parent function of f(x)=(x+3)3
Answer:
g(x) = x^3
Step-by-step explanation:
f(x)=(x+3)^3
The parent function is
g(x) = x^3
The function was shifted to the left 3 units from the parent function
f(x) = ( x- -3) ^3
f(x) = ( x+3) ^3

2 g + 6 x - 14 = 0 2 g = -2 (3 x - 7)
x = 7/3 - g/3
Step-by-step explanation:
Solve for x:
2 g = 14 - 6 x
2 g = 14 - 6 x is equivalent to 14 - 6 x = 2 g:
14 - 6 x = 2 g
Subtract 14 from both sides:
-6 x = 2 g - 14
Divide both sides by -6:

At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x-axis?
The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of factor
(x-5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis
(x+2)^2 has the power of 2 which is an EVEN number. An Even power means that the graph will touch the x-axis
To find where it will touch the axis set the factor equal to zero and solve .
(x + 2) = 0
Subtract 2 from both sides
x=-2

Solve the equation. 1.25 =0.75+r
Answer:
0.50
Step-by-step explanation:
Do the opposite of addition
So 1.25 - 0.75
The solution to the equation 1.25 = 0.75 + r for r is r = 0.5
How to determine the solution to the equation for rFrom the question, we have the following parameters that can be used in our computation:
1.25 = 0.75 + r
Add -0.75 to both sides of the equation
so, we have the following representation
-0.75 + 1.25 = 0.75 + r + -0.75
Evaluate the like terms on the right hand side
This gives
-0.75 + 1.25 = r
Evaluate the like terms on the left hand side
This gives
0.5 = r
Rewrite as
r = 0.5
Hence. the solution is 0.5

Answer:
y > 4/3 x - 2.
Step-by-step explanation:
First find the equation of the dashed line:
The slope (-6-2)/(-3-3)
= -8/-6
= 4/3.
y - y1 =m(x - x1) where m = slope and (x1,y1) is a point on the line.
y - 2= 4/3(x - 3)
y = 4/3(x - 3) + 2
y = 4/3 x - 2
As the shading is above the line the answer is
y > 4/3 x - 2.
Answer: A

Answer:
Function f(x) is positive for the values x ≤ -6 and x ≥ -2 and negative in the interval -6 ≤ x ≤ -2.
Step-by-step explanation:
As given in the graph,
Given function is a quadratic function, f(x) = (x + 2)(x + 6)
With x-intercepts of the function, x = -6 and -2
Graph below the x-axis represents the negative values of the function.
Graph above the x-axis represents the positive values of the function.
Therefore, function f(x) is positive for the values x ≤ -6 and x ≥ -2 and the function is negative in the interval -6 ≤ x ≤ -2.
