To make it easier, move the equation around so you can find y easier. add 10x to both sides to get y = 10x + 4
Then plug in each value for x.
-2 -> -10*-2 + 4 = 24
-1 -> -10 *-1 + 4 = 14
0 -> -10*0 + 4 = 4
1 -> -10*1 + 4 = -6
2 -> -10*2 + 4 = -16
Answer:
Constant, $19/sweater
Step-by-step explanation:
You can check each of data by dividing cost/number.
38÷2=19
76÷4=19
133÷7=19
171÷9=19
Doing this will tell you the price of 1 sweater, which is $19.
Answer:
6 bars is .283 each and 4 bars is .2875 SO... 6 bars is the better buy.
Step-by-step explanation:
Answer:
Science problems= 12
Math problems= 27
Step-by-step explanation:
If
x= math problems for solving
y= science problems for solving
x+y=39
y=x-15
Using substitution method:
x+(x-15)=39
2x-15=39
2x=39+15
x=(39+15)/2
x=27
Having "x" lets find out "y" value.
x+y=39
27+y=39
y=39-27
y=12
