Answer:
No, Yes, No, No.
Step-by-step explanation:
"It is not the case that x is equal to 100." This means that x ≠ 100.
"x is not equal to 300." The problem has nothing to do with 300. We know that x ≠ 100, but the fact that x ≠ 300 doesn't prove or deny anything about the statement x ≠ 100.
"x is equal to 100." This is the complete opposite of the original statement! If x = 100, then this completely denies or negates the fact that x ≠ 100.
"It is not the case that x is equal to 400." Again, 400 has nothing to do with the statement x ≠ 100, so the statement neither proves nor denies the statement x ≠ 100.
"x is equal to 300." Same story: 300 has nothing to do with x ≠ 100, so it doesn't change anything about x ≠ 100.

What is the equation of the line that passes through the point (2, 1) and has a
slope of 3/2?
Answers
Given :-
A line having a slope of 3/2 passes through (2,1) .To Find :-
The equation of the line .Answer :-
According to the question ,
m = 3/2 Point = (2,1)We know Point slope form of the line as ,
y - y¡ = m ( x - x ¡ )Substitute ,
y - 1 = 3/2 ( x - 2 ) y - 1 = 3/2x - 3/2*2y - 1 = 3/2x - 3 2( y -1) = 3/2x *2 - 3*22y - 2 = 3x - 6 3x - 2y -4 = 0Hence the equation of the line is 3x -2y-4=0 .
Answer:
Step-by-step explanation:
Use the form y = mx + b and plug in your known point
y = 3x/2 + b
1 = 3(2)/2 + b
1 = 3 + b
b = -2
y = 3x/2 - 2

a. Maximum volume
b. length of side of square: x=

Answers
Answer:
Step-by-step explanation:
V = x(14 - 2x)(18 - 2x)
V = (14x - 2x²)(18 - 2x)
V = (252x - 28x² - 36x² + 4x³)
V = 4x³ - 64x² + 252x
V' = 12x² - 128x + 252
0 = 3x² - 32x + 63
x = (32 ±√(32² - 4(3)(63))) / (2(3)
x = (32 ± √268) / 6
x = 8.06 inches, which we ignore as this would mean we have no material left at all in the 14 inch dimension.
or
x = 2.60488... 2.60 inches
Vmax = 0.60(14 - 2(2.60))(18 - 2(2.60)) = 292.86478... = 292.86 inches³

Find the equation of a line that contains the points (-3,-1) and (-4, -7). Write the equation in slope-intercept form.
Answers
Answer:
y = 6x + 17
Step-by-step explanation:
First you can find the slope:
m = (y2-y1) / (x2-x1)
m = (-7 - (-1)) / (-4 - (-3))
m = (-7 + 1) / (-4 + 3)
m = -6 / -1
m = 6
_______
Then we can plug what we know into the point-slope form:
y - y1 = m (x - x1)
(you can pick either one of the points to plug in as (x1, y1))
y - (-7) = 6 (x - (-4))
y + 7 = 6 (x + 4)
_______
Now we can change the point-slope form into slope-intercept form by solving for y:
y + 7 = 6 (x + 4)
y + 7 = 6x + 24
y = 6x + 17

Consider the parabola given by the equation: y = 1x^2 - 12x + 27
A) the vertex = (_,_)
B) the y-intercept is the point (0,_)
C) find the two values of x that corresponds to the x intercepts of the parabola and write them as a list separated by commas:
X= ___
Answers
Answer:
vertex: (6, -9)
y intercept: (0, 27)
X = 3, 9
Step-by-step explanation:
Finding Vertex (Part A)
Consider the formula -b/2a. This formula gives you the x-coordinate of the vertex.
y = 1x^2 - 12x + 27
a = 1
b= -12
c =27
-b/2a = - (-12)/2(1) = 12/2 = 6 (x-coordinate of vertex)
When solving for the y-coordinate of the vertex you will need to substitute your 'x" back into the equation.
y = 1(6)^2 - 12(6) + 27
y = 36 - 72 + 27 = -9 (y-coordinate of vertex)
--------------------------------------------------------------------------
Y- Intercept (Part B)
When looking for the y-intercept your "x" must always be 0.
Substitute 0 in every "x" in equation.
y = 1(0)^2 - 12(0) + 27
y = 27
y intercept: (0, 27)
------------------------------------------------------------------------------
X- Intercepts (Part C)
To find the values of "x" factor.
y = 1x^2 - 12x + 27
0 = 1x^2 - 12x + 27
0 = (x - 3 )(x - 9 )
(x-3) = 0 (x-9) = 0
x = 3 x = 9

The mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.
The mapping represents y as a function of x, because each x-value is related to exactly one y-value.
The mapping does not represent y as a function of x, because there are more x-values than related y-values.
The mapping represents y as a function of x, because each y-value is related to exactly one x-value.
Answers
Answer:
The mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.
Step-by-step explanation:
See it's not a function
Because In a function every c value has a unique y value.Here there is 4 values for one x .So it's a relationThe statement which is true about this mapping is the mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
WE have been given a domain figure.
We can see that the input values has more than one output values.
therefore, it cannot be a function Because in a function every input value has a unique y value.
Here there is 4 values for one x input.
x = 3
y = 2, 4, 5, 6
So it's a relation
Hence, the statement which is true about this mapping is the mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

guys pls answer my question i am very confused

You’ll have to solve for y:
Start by distributing 5 into (3 + y):
2y = 5(3 + y)
2y = 15 + 5y
Subtract 15 from both sides:
2y - 15 = 15 - 15 + 5y
2y - 15 = 5y
Then, subtract 2y from both sides:
2y - 2y - 15 = 5y -2y
-15 = 3y
Then , divide both sides by 3 to solve for y:
-15/3 = 3y/3
-5 = y
Therefore, y = -5
You’re solving for Y
