What is 3k +2 ( 5k - 3) = 7
polet [3.4K]

Answer:

k= -0.2

Step-by-step explanation:

3+2(5k-3)=7              (original)

3+10k-6=7                 (distribute 2 in (5k-3))

9+10k=7                    (combine like terms 3+-6)

10k=-2                       (subtract 9 on both sides to isolate k)

k=-0.2                       (divide 10 on both sides to get you're answer/isolate k)

Find the slope and y-intercept for this table.​
labwork [276]

Answer:

See below:

Step-by-step explanation:

To find the slope, we use the following formula:

\frac{y_{2} - y_{1} }{x_{2} - x_{1} }

For this case, we can use (6,60) as the first set of points.

We can use (4,70) as the second set of points.

Now, we can use the formula, 70-60 is for the top of the fraction (10)

We can do 4-6 to find the bottom, which is (-2)

Now, if we add the fraction back we get -> 10/-2 which is -5 for slope!

To find out the y intercept, it in simple words is "What is y when x is 0?".

We can do that by using the slope intercept formula: y=mx+b.

Once we insert our slope which is -2 we get: y=-2x+b

We can now substitute a point, lets use (6,60) so we can find out b.

We now get the equation: 60=-5(6)+b.

If we solve for that we get 90!

Once we input that, we get, y=-5x+90

Now we put in x as 0 and we get our y intercept as 90!
