I just need help with the table
navik [9.2K]
-2, 0, 2, and 4 are the x values. To find y, we must substitute x for each of these values in y = -3/2x + 2.

-3/2 times -2 = 3. 3 + 2 = 5. The y value that goes with -2 in the table is 5.

-3/2 times 0 = 0. 0 + 2 = 2. The y value that goes with 0 is 2.

-3/2 times 2 = -3. -3 + 2 = -1. The y value that goes with 2 is -1.

-3/2 times 4 = -6. -6 + 2 = -4. The y value that goes with 4 is -4.

So, the table/coordinates are:

(-2, 5)
(0, 2)
(2, -1)
(4, -4)

I hope this makes the process clear.

If the current price of bread dropped by 44 cents, 9 loaves of bread would cost as much as 7 do now. What is the current price o
tatiyna
Let current price = x cents
prior price = x+44 cents
9 loaves at current price cost 7 at prior price, so
9x=7*(x+44)
expand and rearrange,
2x=7*44=308
x=154
So the current price is $1.54

The total cost of lunch is $3.50, consisting of a juice, a sandwich, and a pear. The juice cost 1.5 times as much as the pear. T
vodka [1.7K]

The price of the pear is $0.6

Given:

The total cost of lunch is $3.50, consisting of a juice, a sandwich, and a pear.The juice cost 1.5 times as much as the pear.The sandwich costs $1.40 more than the pear.

From above statements

Juice + sandwich + pear = $3.50      -----------eq(1)

Juice = 1.5 * pear

sandwich = pear + $1.40

substitute juice and sandwich values in eq(1)

1.5 pear + pear + $1.40 + pear = $3.50

3.5 pear = $3.50 - $1.40

pear = $2.10/3.5

pear = $0.60

Hence the price of the pear is $0.6
