y=-2
Step-by-step explanation:
if line has zero slope (b) it means that b is undefined.
if x=0 y=-2 because line has no slope. so b=-2
y=-2
Answer:
x=8+1/2
Step-by-step explanation:
Hope this helps, good luck!
If you mean it costs $1.49 to buy 10 items, then the unit rate is $0.15 or 15 cents
This is because you divide 1.49 over 10 like so: 1.49/10 = 0.149, then round this to the nearest penny to get 0.15
0.15 dollars = 15 cents
so basically whatever this item is, it costs 15 cents per item
Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.
Answer:
The card was worth $160.
Step-by-step explanation:
It is given that:
Percent of gift card used = 42%
Cost of groceries = $67.20
Let,
x be the total amount on gift card.
42% of x = 67.20

0.42x = 67.20

Therefore,
The card was worth $160.
