Can some one help please just need equation worth 15point
1 answer:
Explanation:
Let's say we're buying only 8 dollars of stuff. 8 dollars can only be formed, in this case, by 2 oyster shell grit bags, since they costs 4 dollars each.
Now, we already bought 2 oyster shell grit bags, now we have to buy sunflower seeds. Let's say we're buying only 20 dollars of sunflower seeds. 20 dollars can only be formed, in this case, by 4 sunflower seeds bags since they cost 5 dollars each.
Equation:
x will be the number of oyster shell grit bags and 6 - x will be the number of sunflower seeds bags.
4x + 5(6 - x) = 28 → we combine the price with the corresponding variables.
4x + 30 - 5x = 28
4x - 5x = 28 - 30
-1x = 28 - 30
-1x = -2
x = -2 / -1
x = 2
So, if <em>x = 2</em>, <em>6 - x</em> =<em> 6 - 2</em> which equals 4.

Step 1: 3x + 4y = 15
Step 2: Get in Slope intercept form = y=mx+b
Step 3: Subtract 3x from both sides since your trying to get Y alone
Step 4: 4y = -3x + 15
Step 5: Divide 4 from both sides since 4 cannot go into -3 or 15 leave it as is
Step 6: Y =
+ 
Step 7: Point slope form= y-y=m(x-x)
Step 8: (8, -2) are your points 8x and -2y
Step 9: Substitute
Step 10: y - 2 =
(x - 8)
Step 11: Distribute
Step 12: y - 2 =
+ -6
Step 13: Add 2 to both sides
Answer : y =
+ 4
