Draw a conclusion is the statment below always, sometimes, or never true ? Bive at least two examples to support your reasoning. The lcm of two numbers is the product of the two number discuss your conclusion with a partner
Answer:
Sometimes
Step-by-step explanation:
Example 1:
Take two numbers as [tex]7,8[/tex]
LCM of [tex]7,8=7(8)=56[/tex]
In this case, the lcm of two numbers is equal to the product of the two numbers.
Example 2:
Take two numbers as [tex]6,3[/tex]
[tex]6=3(2)[/tex]
So,
LCM of [tex]6,3=3(2)=6[/tex]
In this case, the lcm of two numbers is not equal to the product of the two numbers.
Therefore,
Sometimes, the lcm of two numbers is equal to the product of the two numbers.
What is the slope of line that passes through the points (-3,8) and (1,32)?
Answer:
6
Step-by-step explanation:
use the formula of slopes
[tex] = \frac{y2 - y1}{x2 - x1} \\ = \frac{32 - 8}{1 - ( - 3)} \\ = \frac{24}{4} \\ = 6[/tex]
Answer:
[tex]\frac{31 }{11 }[/tex]
Step-by-step explanation:
The formula to solve this is: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. In this case, the expression would be: [tex]\frac{32 -1 }{8 -(-3) }[/tex] or [tex]\frac{32 -1 }{8 +3 }[/tex]. This is also [tex]\frac{31 }{11 }[/tex].
Hope it helps and is correct!

ty
Im not for sure.. but I think it would be something like 3,9
Answer:
We rearrange the first equation into y = 8x - 42 and we substitute it in to get
-4x - 6 = 8x - 42 so 12x = 36 so
x = 3 and y = -18
hope this helps and brainliest please

What is the solution to the system of equations?
x = -4y
3x + 2y = 20
Answer:
(x, y) = (8, -2)
Step-by-step explanation:
Substitute:
3(-4y) + 2y = 20
-12y + 2y = 20
-10y = 20
y = -2
x = -4(-2) = 8

A city receives 2 inches of snowfall every 3 hours. Write and graph a function that describes the relationship. How long does it take to receive 1 foot of snow? Use x for the independent variable and y for the dependent variable.
Answer:
To receive 1 foot of snow it will take about 18 hours.
Step-by-step explanation:
Given that a city receives 2 inches of snowfall every 3 hours, to write and graph a function that describes the relationship and determine how long does it take to receive 1 foot of snow, the following calculation must be performed:
1 foot = 12 inches
(12/2) x 3 = X
6 x 3 = X
18 = X
Thus, to receive 1 foot of snow it will take about 18 hours.
