describe the steps you would take to transform the equation 10x + 2y = 25 into the equation y = -5x + 25/2
saveliy_v [14]
10x + 2y = 25
Then rearrange the equation to get 10x on the same side as 25.

Keep in mind, once bringing to the other side, your constant and variable will switch to a negative or positive for example,
-10x will become +10x. Another example is +20x will become -20x once brought to the other side.

Continuing on once rearranged, your equation will look like,
2y = - 10x + 25

Then we have to get rid of the 2 on 2y so you will have to divide both sides by 2.
\frac{2y}{2} = \frac{ - 10x + 25}{2}
Dividing both sides by 2, you will get,
y = - 5x + \frac{25}{2}
The reason why we don't divide and rather keep the 25/2 (25 divded by 2) is because 25 divided by 2 will give an answer with a decimal and that we don't want a decimal in our equation so we just keep it the way it is. If you ever get a decimal, make sure you keep it in its fraction form.

To paint a house, a painting company charges a flat rate of $500 for supplies plus $50 for each hour of labor. What is the slope
Nataly_w [17]
The slope of the line is 50. You can try looking at the equation, which is

y=50x+500

500 is your y-intercept, and is where the cost starts.

50 is your slope, since the cost goes up by $50 every time.

x is how many hours, which determines how many $50s there are.

I hope this helps. All in all, the slope is 50.

Write an exponential function that passes through the points (0, 3) and (-1, 6)
FinnZ [79.3K]
Standard form of an exponential function is y=ab^x
when x=0, y=3, 3=ab^0, so you can figure out that a=3
when x=-1, y=6, 6=3b^(-1), b^(-1)=2, b=1/2
so the equation is y=3(1/2)^x
