Use formula y = mx+ b Y is your point y in the pair: 7
M is slope : 6
X is your x in the pairs : -3
7 = 6 (-3) + b
7 = -18 + b
7+ 18 = b 25= b
So , it will be Y= 6x + 25
Answer:
$40.82
Step-by-step explanation:
Subtract $11.36 from $100 and you'll get $88.64 and then just subtract $47.82 and the answer is $40.82. Not sure if u know how to subtract but just line the decimals up and take the smaller number away from the bigger one so in this case it would just be 100-11.36=88.64 and since he spent more money it would be 88.64-47.82=40.82
Answer:
- cookie: $1.25
- cupcake: $2.75
Step-by-step explanation:
Let x and y represent the cost of a cookie and a cupcake, respectively.
4x +3y = 13.25
5x +2y = 11.75 . . . . . . the system of equations
___
By Cramer's rule:
x = (3(11.75) -2(13.25))/(3(5) -2(4)) = 8.75/7 = 1.25
y = (13.25(5) -11.75(4))/7 = 19.25/7 = 2.75
The cost of one cookie is $1.25; the cost of one cupcake is $2.75.
