(7x-26) (5x-27) (10x-23)
Answer:
-547
Step-by-step explanation:
(7×-26) = -182
(5×-27) = -135
(10×-23) = -230
-182+ - 135 + -230
= -317 + -230
= -547

Some times it's really very easy to answer the problem just by looking over the given problem.
For the given graph, we need to observe some(or any) point on the graph that can conclude anything to answer the given problem.
Generally we observe x or y-intercepts of the graph first.
Let us observe the y-intercept of the given graph, because we can see a clear picture of y-intercept there.
By looking on the graph, we can see y-intercept is at -1.
Note: y-intercept is a point on y-axis where value of x is 0.
Now let us observe the given functions in the given options.
First option: If we plug x=0 in the given function, we get f(0)=0.
So, y-intercept for first option is 0.
Second option: If we plug x=0, we get a negative -1 inside radical. Cube root of -1 is -1. On multiplying by -1 we get +1.
So, y-intercept for second option is 1.
Third option : If we plug x=0 in that function, we get 0-1 = -1.
So, the y-intercept for third function is -1.
Therefore, function in third option is the correct function for given graph.
Therefore, third option [tex]f (x) = \sqrt[3]{-x} -1[/tex] is correct option.

What is the cubic Function?A polynomial equation with a 3-exponent greatest exponent is called a cubic equation. Despite having many more uses for understanding more complex mathematics, such as calculus, cubic equations are frequently employed to calculate volumes.
Given a graph of a cubic function for calculating the cubic function we need to standardize it. since it's a single aggregate graph that standard function would be.
x = a(y + 1 )³
for the value y tends to -1. "a" will be -1.
Hence,
x = -1 (y+1)³
(y + 1 )³ = -x
y+1 = ∛-x
y = ∛-x -1
Therefore, for the given graph F(x) = y = ∛-x -1.

What is the value of x in the equation - 24

I need help ASAP please :(((((
Step-by-step explanation:
Number 1
For parallelism.....
gradient of the two lines is the same
y = 3/2x -4
y = mx + C
m = 3/2
(-1, 0) = (x1, y1)
y - y1 = m(x - x1)
y - 0 = 3/2[x - (-1)]
y = 3/2(x + 1)
2y = 3x + 3
y = 3/2x + 3/2
Option A
Number 2
For parallelism.....
gradient of the two lines is the same
y = -½x + 2
y = mx + c
m = -½
(-2, -1) = (x1, y1)
y - y1 = m(x - x1)
y - (-1) = -½[x - (-2)]
y + 1 = -½(x + 2)
2(y + 1) = -(x + 2)
2y + 2 = -x - 2
2y = -x - 2 - 2
2y = -x - 4
y = -½x - 2
Option A
Number 3
For perpendicularity... m1 × m2 = -1
y = 4/3x - 5
y = mx + c
m1 = 4/3
m2 = -1/m1
m2 = -1/(4/3)
m2 = -3/4
(3, -1) = (x1, y1)
y - y1 = m2(x - x1)
y - (-1) = -¾(x - 3)
y + 1 = -¾(x - 3)
4(y + 1) = -3(x - 3)
4y + 4 = -3x + 9
4y = -3x + 9 - 4
4y = -3x + 5
y = -¾x + 5/4
Option A
Number 4
For perpendicularity... m1 × m2 = -1
y = -5x + 5
y = mx + c
m1 = -5
m2 = -1/m1
m2 = -1/-5
m2 = ⅕
(5, 4) = (x1, y1)
y - y1 = m(x - x1)
y - 4 = ⅕(x - 5)
5(y - 4) = x - 5
5y - 20 = x - 5
5y = x - 5 + 20
5y = x + 15
y = ⅕x + 15/5
y = ⅕x + 3

1Determine whether the survey sample is biased or unbiased. Explain your answers.
What is your favorite sport? Sample is chosen from people attending a soccer game.
2What is your favorite soft drink? Sample is chosen by picking names out of a telephone book.
4Should more money be put into athletic programs or music programs at school? Sample is chosen from students in the band program.
5What is your favorite vacation destination? Sample is chosen by asking every student in the class.
Answer:
1 is biased, 2 isn't, 3 is biased, 4 isnt
Step-by-step explanation:
If you ask a question to people in a group who are already clearly for a certain topic then it is biased. For survey to not be biased, the people need to be chosen at random. Ask students what their favorite class is, or ask flight attendants where their favorite destination to travel to is. Dont use a group who has any relation to the survey at hand. Asking band students about funding for band is biased, as well as asking people who are at a SOCCER GAME what their favorite sport is.

The area of the triangle △ABC is 12 square units.
The question is incomplete. The actual question is
Triangle ABC is symmetric about the y-axis. Point A is located at (-3,0), and AB is the longest side of ABC. If the perimeter of ABC is 16, what is the area?
What is symmetry?Symmetrical forms or figures are things that can have a line drawn through them so that the representations on both sides of the line mirror each other.
How to solve the problem?As could be seen in the figure the triangle △ABC is symmetric along the y-axis. Hence, the side AC and BC must be of the same length let us call it 'a'. Also, the coordinate of B must be (3,0) because (3,0) is the reflection of (-3,0) corresponding to the y-axis.
And, the length of AB=6 units because the distance between (-3,0) and (3,0) is 6 units.
Now, the perimeter of the triangle is 16 units. Therefore,
2a+6=16
⇒a=(16-6)/2
⇒a=5 units.
Hence, we have an isosceles triangle △ABC we can find the height 'h' of the triangle using the Pythagoras theorem. Consider the triangle △ACE
then we have that
the height of the right triangle △ACE= h
the base of the right triangle △ACE= 3 units
the hypotenuse of the right triangle △ACE= a = 5 units.
Hence, by Pythagoras' theorem
h²+3²=5²
⇒h²=25-9=16
⇒h=4 (we choose the positive value of h because length is always positive)
Hence, the area of the triangle △ABC is
(1/2)×base×height
=(1/2)×AB×CE
=(1/2)×6×4 unit²
=12 unit²
Hence, the area of the triangle △ABC is 12 square units.

Which expression represents the total surface area, in square centimeters, of the square pyramid? A square pyramid. The square base has side lengths of 8.2 centimeters. The triangular sides have a height of 10.3 centimeters.
Answer:
Total surface area of the pyramid is 236.16cm² and the expression is
2bs + s²
Step-by-step explanation:
Total surface area of a square pyramid is expressed as;
TSA = 2bs + Base Area
b is the side length of the base = 8.2cm
s is the slant height of the triangular side = 10.3cm
Base area = s²
Base area = 8.2²
Base area = 67.24cm²
TSA = 2(8.2)(10.3)+67.24
TSA = 168.92+67.24
TSA = 236.16cm²
Hence the total surface area of the pyramid is 236.16cm² and the expression is 2bs + s²
