2(5x-7)=2x+10 what Is the distributive property
Answers
2(5x)= 10x
2(-7)=-14
10x-14=2x+10
Solve:
10x-2x=8x
8x-14=10
14+10=24
8x=24
24/8=3
X=3

Ok so we can see for every 2 cups of medium coffee, the balance goes down 5.30$. So that means that for every coffee, her balance goes down 2.65$. Solving for the x-intercept means how many medium coffees can I get until my balance is 0. First, we have to find the y-int so it's easy. The slope is -2.65 because for every medium coffee, her balance goes down 2.65$. So we have y=-2.65x+b. Plugging in any point, I choose (4,14.40), we get 14.4 = -2.65 × 4 +b. Solving for b we get 25 for the y intercept, meaning the equation is y = -2.65x + 25 . To find the x intercept, we set y=0. So we have 0 = -2.65x+25. Solving for x we get approx. 9.4. We can't have decimals so we round down to 9. So the x int is ≈ 9.4 meaning we can only buy 9 coffee and have a little extra. But, if the problem said how many more coffees can she get, then here is how we do it. Since she already got 4 coffees, and the max is 9, we do 9-4 and we get 5, so she can buy 5 coffeed more.

I can't imagine. All you have to do is pick any old number, divide the
top and bottom of the fraction by it, and you'll have a new fraction that's
equivalent to 50/100 . And if the number you pick is 2, 5, 10, or 25,
then the new fraction will even have whole numbers on top and bottom.
You can even pick any old number, multiply the top and bottom of the
fraction by it, and you'll have a new fraction that's equivalent to 50/100 .
Can't imagine what's so hard about that.

When you round to the nearest 10 thousand. Find the number in the 10 thousand place, that would be the 6 in this case, now look at the number to the right of it, if that number is 5 or higher, then your 67,000 becomes 70,000.
If the number to the right of place value is lower than 5 then it would have been rounded to 60,000.
Hope this helps you. :-)
Round the number BEHIND the ten thousand and you have your answer.

Find slope-
x-intercept-
y-intercept-
Answers
get the equation in slope intercept form
2x-3y=9
subtract 2x from each side
-3y = -2x +9
divide by -3
y = 2/3 x -3
slope = 2/3
y intercept = -3
x intercept set y=0 and solve
0 = 2/3 x -3
add 3 to each side
3 = 2/3 x
multiply each side by 3/2
9/2 = x
the x intercept is 9/2 or 4 1/2
y=(2x-9)/3
y=(2/3)x-3
slope(m)=2/3
finding x-intercept..
if y=0
2x-3(0)=9
x=9/2
finding y-intercept..
if x=0
2(0)-3y=9
y=-3
