Answer:
42 Hours.
Step-by-step explanation:
As an equation where y is the total pages and x is hours of class:
y=1+1x since she started with 1 page and does 1 page per hour.
Setting the total pages she needs as 43 (y=43) we get:
43=1+1x
Subtract one on both sides
42=1x
The 1 doesn't need to be written so
x=42
Therefore, it'll take her 42 hours to write all those notes.
Determine whether the equation below has a one solutions, no solutions, or
an infinite number of solutions. Afterwards, determine two values of x that
support your conclusion.
HELP PLEASE
Answer/Step-by-step explanation:
The equation, [tex] \frac{20}{x} = -5 [/tex] has one solution, x.
The value of x that will make the equation true, that is the number we can substitute for x into the equation that will make what we have on our left side equal to what we have on our right side is -4.
Substitute -4 for x in the equation and simplify:
[tex] \frac{20}{-4} = -5 [/tex].
Simplifying the equation:
[tex] -5 = -5 [/tex] (this is true).
A value of x that can make the equation false is 4.
Thus, replace x with 4, then simplify.
[tex] \frac{20}{x} = -5 [/tex]
[tex] \frac{20}{4} = -5 [/tex]
[tex] 5 = -5 [/tex] (false. 5 ≠ -5)

(-3+4k) - (-2+ 7k)
Answer: −1−3k
Step-by-step explanation:
Distribute:
(−3+4k)−1(−2+7k)
(-3+4k)+{2-7k}
Eliminate redundant parentheses:
(−3+4k)+2−7k
-3+4k+2-7k
Add the numbers:
−3+4k+2−7k
−1+4k−7k
Add the same term to both sides of the equation:
−1+4k−7k
−1−3k

Please solve -21+6x=3(3x-5)-x
Answer:
x=-3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−21+6x=3(3x−5)−x
−21+6x=(3)(3x)+(3)(−5)+−x(Distribute)
−21+6x=9x+−15+−x
6x−21=(9x+−x)+(−15)(Combine Like Terms)
6x−21=8x+−15
6x−21=8x−15
Step 2: Subtract 8x from both sides.
6x−21−8x=8x−15−8x
−2x−21=−15
Step 3: Add 21 to both sides.
−2x−21+21=−15+21
−2x=6
Step 4: Divide both sides by -2.

Lcm of 4 and 15?
least common multiple
=================================================
Explanation:
Multiply the two values to get 4*15 = 60
Then divide by the GCF 1 to get 60/1 = 60. The GCF being 1 means the result hasn't changed.

Another example would be: "Find the LCM of 6 and 8". We would first do 6*8 = 48, then divide by the GCF 2 to get 48/2 = 24. The LCM of 6 and 8 is 24.

Function h is a transformation of the parent exponential function, f(x)=2^x. h(x)=-3*2^x Which statement is true?
A. Function h is a vertical translation of function f. B. Function h is a reflection and a dilation of function f. C. Function h is a reflection and a translation of function f. D. Function h is a horizontal translation of function f.
Answer:
Function is a reflection and dilation of function f.
Step-by-step explanation:
A reflection gives the mirror image of function.
A function can be reflected about an axis by multiplying by -1.
To reflect function about the x-axis, multiply f(x) by -1 to get -f(x).
The correct option is: B. Function h is a reflection and a dilation of function f.
-----------------------
The functions are:
[tex]f(x) = 2^x[/tex]
[tex]g(x) = -3 \times 2^x[/tex]
It can be seed that g is f multiplied by -3.
The multiplication by a constant means that a dilation happened.Since the constant is negative, it means that a reflection also happened.In the image at the end of this question, it can be seen that the g, the blue graph, is a reflected and dilated version of f, the red graph.
Thus, the correct answer is:
B. Function h is a reflection and a dilation of function f.

HELPPP PLEASEEEE I NEED THE ANSER Select the most precise and correct definition of parallel lines from among those that are given. Choose 1 answer: (Choice A) A Two distinct lines are parallel if one can be rotated to sit on top of the other. (Choice B) B Two distinct lines are parallel if they point in the same direction. (Choice C) C Two distinct lines are parallel if they are in the same plane and never intersect each other.
Answer:
C. Two distinct lines are parallel if they are in the same plane and never intersect each other.
Step-by-step explanation:
Parallel lines are best defined as 2 different lines that are in the same plane and will never intersect each other at any point in the graph.
They are always the same distance apart and will never touch.
So, C is correct
Answer:
C
Step-by-step explanation:
The very definition of parallel lines is that they have the same slope, if they have the same slope, they will never meet.
Rearrange the equation below to solve for y ax + 6y = 24
y = 4 - ax / 6
ax + 6y = 24
ax - ax + 6y = 24 -ax
6y / 6 = 24 / 6 - ax / 6
y = 4 - ax / 6
How are linear equations and linear inequality similar and different?
Answer:
The graph of linear inequalities include a dashed line if they are greater than or less than but not equal to. Linear equations, on the other hand, include a solid line in every situation. Moreover, linear inequalities include shaded regions whereas linear equations do not.

Choose which property of equality is demonstrated moving from step a to step b. a. If b = 3, and m = 5, and y = mx + b then, b. y = 5x + 3
Answer:
add the = problome
Step-by-step explanation:
The property of equality is demonstrated moving from step a to step b is linear.
What is a linear equation?The linear equation is defined as the equation having a degree of one or the power of the variable will be one. The linear equation is represented by y = mx + c. Here y is the variable, m is the slope and, c is the intercept.
Given that b = 3, and m = 5, and y = mx + b then, b. y = 5x + 3. The equation can be formed as below:-
y = mx + c
y = 5x + 3
Therefore, the property of equality is demonstrated moving from step a to step b is linear.

What is the opposite value of -(-9) ?
Answer:
9
Step-by-step explanation:
two negatives make a positve
Answer:
-9
Step-by-step explanation:
Whenever you are given an expression, first look at it. Since there are two negative signs in the equation, they cancel out, leaving a nine. The opposite value most likely means that the sign is the opposite, so you end up with -9 as the value.

11. Higher Order Thinking Using what you know
about angle pairs formed by parallel lines and a
transversal, how are 21, 22, 23, and 24 related
in the trapezoid? Explain.
3
Answer:
m∠1 + m∠3 = m∠2 + m∠4
Step-by-step explanation:
In the figure attached,
In the given trapezoid if two sides AB and CD are parallel and AD is a transverse,
m∠1 + m∠3 = 180°
Similarly, if AB and CD are parallel and BC is a transverse,
m∠2 + m∠4 = 180°
Therefore, m∠1 + m∠3 = m∠2 + m∠4 is the relation between these angles.
Write an equation of the parabola in vertex form.
Answer:
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. ... When written in "vertex form": • (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.
Answer:
y =0.25(x-4 )^{2}-1
Step-by-step explanation:
The formula of vertex form is as follows:
Y = a(x-h)^2+k
h = the x value for the vertex (in this case it is 4)
k = the y value for the vertex (in this case it is -1)
If you input these into the equation you are left with:
Y = a(x-4)^2-1
To find 'a' I just entered this equation into the Desmos calculator and messed around with the value until the y-intercept was (8,3)
