Pls help <br>Lcm of 4 and 15? <br>least common multiple
kakasveta [241]
<h3>Answer:  60</h3>

=================================================

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.

What is the slope of the line that passes through the points (1, 1) and (4, 4)?
gizmo_the_mogwai [7]

Answer:

The answer is 1

Step-by-step explanation:

Formula for finding the slope: \frac{y2-y1}{x2-x1}

Take y2 and y1 from (4,<u>4</u>) (1,<u>1</u>)

Take x2 and x1 from (<u>4</u>,4) (<u>1</u>,1)

\frac{y2-y1}{x2-x1}  = \frac{4-1}{4-1} = \frac{3}{3} = 1

This is how the answer is 1

Hope it helps :)

Which is it? , 30 points
goldenfox [79]

Answer:

It's choice B.

Step-by-step explanation:

Let's look the one you have chosen (A):

f(x) =  x - 2/ 7  + 8

x-2 / 7 = f(x) - 8

x- 2 = 7(f(x) - 8)

x = 7(f(x) - 8) + 2

The inverse)= 7(x - 8) + 2

So it's not A.

B.  f(x) = 5(x/4) - 3

5x / 4 = f(x) + 3

5x = 4(f(x) + 3)

x = 4(f(x) + 3 / 5

So the inverse is  4(x + 3) / 5

So it is B.

Simplify:<br> 5/4x-8y-1/4x+7y+3<br> A)x-y+3<br> B)3/2x+y+3<br> C)3/2x-y+3<br> D)x+y+3
Dovator [93]
<span>A)x-y+3 is your answer 

Proof:

(5 x)/4 - 8 y - x/4 + 7 y + 3
Put each term in (5 x)/4 - 8 y - x/4 + 7 y + 3 over the common denominator 4: (5 x)/4 - 8 y - x/4 + 7 y + 3 = (5 x)/4 - (32 y)/4 - (x)/4 + (28 y)/4 + 12/4:
(5 x)/4 - (32 y)/4 - x/4 + (28 y)/4 + 12/4
(5 x)/4 - (32 y)/4 - x/4 + (28 y)/4 + 12/4 = (5 x - 32 y - x + 28 y + 12)/4:
(5 x - 32 y - x + 28 y + 12)/4
Grouping like terms, 5 x - 32 y - x + 28 y + 12 = (28 y - 32 y) + (5 x - x) + 12:
((28 y - 32 y) + (5 x - x) + 12)/4
28 y - 32 y = -4 y:
(-4 y + (5 x - x) + 12)/4
5 x - x = 4 x:
(-4 y + 4 x + 12)/4
Factor 4 out of -4 y + 4 x + 12:
(4 (-y + x + 3))/4
(4 (-y + x + 3))/4 = 4/4×(3 + x - y) = 3 + x - y:
Answer:  3 + x - y
