Answer:

1/8

Step-by-step explanation:

First you substitute b for -6.

-6 + 7 = -1

Then you substitute a for -4

2× -4 = -8

Now you have -1/-8, but because they are both negative the solution becomes positive

PLEASE HELP!!!!!
kipiarov [429]

Answer:X + Y ≥ 4

$2.20X + $2.95Y ≤ $10.00

Strawberries cost $2.20 per pound

Raspberries cost $2.95 per pound

Jada only has $10.00 to spend

She wants to buy at least 4 pounds

Assumption: She buys X pounds of strawberries and Y pounds of raspberries.

<u />

<u>Solution:</u>

Number of pounds can't be less than 4

i.e X + Y ≥ 4

The cost of buying strawberries and raspberries has to be $10.00 or less than $10.00

i.e $2.20X + $2.95Y ≤ $10.00

So the system of equations is;

X + Y ≥ 4

$2.20X + $2.95Y ≤ $10.00

Step-by-step explanation:

Hopefully this helped, if not HMU and I will get you a better answer.

<em>-Have a great day! :)</em>
