Answer: (2,2), (4,2)
First, I subtracted 2y from both sides of the second equation. Then, I substituted -2y+6 in for x in the first equation (-2y+6)²+4y²=20. Then, I expanded 4y²-24y+16+4y²=20. Next, I combined like terms, and moved everything to one side 8y²-24y+16=0. Then, I factored out an 8, and then finished factoring 8(y-2)(y-1). This gives me my y-values, y=1,2. Next, I inserted each y-value into the second equation and got x=-2(1)+6 ---> x=4 (The first solution is (4,1). ) and x=-2(2)+6----->x=2 (The second solution is (2,2).
Answer:
100%
Step-by-step explanation:
All of them = 100%.
If your choices are
A. C = 2.99x - 50
B. C = 50 - 2.99x
C. C = 50x - 2.99
D. C = 2.99 - 50x
2.99x
That’s the money you owe for the cherries. That eliminates choices C and D.
50 - 2.99x
When x is zero you should get 50 dollars back, so that eliminates A. You get 50 dollars back minus the money that you owe for the cherries, so that's choice B.
B. C = 50 - 2.99x
Answer:
see explanation
Step-by-step explanation:
A
note from the table that the cost increases by $15 for each package, then this is the multiplier for the cost.
let n be the number of packages , then
cost = 15n
B
to find the cost of 7 packages , substitute n = 7 into the rule
cost = 15 × 7 = $105
I believe the answer would be 3.96 simplified
