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.
Answer:
60

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.

Here, 10x and 5x are like terms. so add them
10x + 5x + 3y = 15x +3y
2)2x + 7y +4x + 6x = 2x + 4x + 6x + 7y = 12x + 7y

(-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
A cope machine makes 32 copies per minute. How many copies does it make in 4minutes and 15 seconds?
Answer:
136
Step-by-step explanation:
4 times 32 = 128
32/4=8
128+8=136
Answer:
135
Step-by-step explanation:
1. divide 32 by 60 to get how many copies per second
[tex]32/60 = 0.533[/tex]
2. convert 4min and 15 sec to seconds
it is 255 seconds
3. Multiply copies per second by number of seconds
[tex]0.533(255) = 135.91[/tex]
4. Round down to whole number because you can't copy part of a paper
Simplify.

Find the missing dimensions. Use the scale factor 1 inch:12 feet. A plastic toy bird has a wingspan of 5 inches. What is the actual bird wingspan? USE NUMBERS ONLY Your answer
Answer: 60 feet
Step-by-step explanation:
Fron the question, we have been told to use a scale factor of 1 inch:12 feet. This simply means that 1 inch has been represented to 12 feet of the actual dimension.
We are further told that a plastic toy bird has a wingspan of 5 inches. The actual bird wingspan will therefore be 5 multiplied by 12 feet and this will be:
= 5 × 12 feet
= 60 feet
A plastic toy bird that has a wingspan of 5 inches has an actual bird wingspan of 60 feet

[tex]3(x + 6) - 2(x + 2) \geqslant 10[/tex]
Answer:
[tex]x\geq -4[/tex]
Step-by-step explanation:
So we have the inequality:
[tex]3(x+6)-2(x+2)\geq 10[/tex]
First, distribute:
[tex](3x+18)+(-2x-4)\geq 10[/tex]
Combine like terms:
[tex](3x-2x)+(18-4)\geq 10[/tex]
Add:
[tex]x+14\geq 10[/tex]
Subtract 22 from both sides:
[tex]x\geq -4[/tex]

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.
−2x
−2
=

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.
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)
