Answer:

The GCF of 40 and 63 can be obtained like this:

The factors of 40 are 40, 20, 10, 8, 5, 4, 2, 1.

The factors of 63 are 63, 21, 9, 7, 3, 1.

The common factors of 40 and 63 are 1, intersecting the two sets above.

Answer:

(-5 , 2 )

Step-by-step explanation:

hello :

×-5y=-15

5y = x+15

y = (1/5)x+3 for x= - 5 y = (1/5)(-5) +3 so : y = 2

What is an equation of the line that passes through the points (6, 0) and (-1, -7)?

Orlov [11]

Answer:

y = x - 6

Step-by-step explanation:

We want to write a line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

First, we need to find the slope, which is just the change in the y-coordinates divided by the change in the x-coordinates:

slope = m = $\frac{6-(-1)}{0-(-7)} =\frac{7}{7}=1$

Our equation now looks like this: y = x + b

Now, to find the y-intercept, let's use one of the points provided and plug those values of x and y into the incomplete equation we have to solve for b:

0 = 6 + b ⇒ b = -6

So, the equation is: y = x - 6.

Hope this helps!

Katarina [22]

Step-by-step explanation:

You can imagine this figure as a rectangle and cube

If you want volume of this irregular figure than you have to do it like this:

V(figure)= V(rectangle)+ V(cube)

V(figure)= a*b*c+ a³

V(figure)= 4*3*(I don't see dimension on the left)+ 3³

V(figure)=12*(I don't see dimension on the left)+ 27

And only you have to to do is to set this dimension which I can't see.

Suppose y varies inversely with x, and y = 25 when x = 1/5. What is the value of y when x = 5 ?

34kurt

Answer:

y = 1

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 25 when x = $\frac{1}{5}$ , then

25 = $\frac{k}{\frac{1}{5} }$ = 5k ( divide both sides by 5 )

5 = k

y = $\frac{5}{x}$ ← equation of variation

When x = 5, then

y = $\frac{5}{5}$ = 1
