<u>Answer:</u>
The correct answer option is b. Darius will get the better deal buying one 16 ounce bottle.
<u>Step-by-step explanation:</u>
We know that a 16 ounce bottle of the salad dressing is for $3.36 while a 10 ounce bottle is priced at $2.30.
Darius has a coupon for 40 cents off if he buys two 10 ounce bottles. We are to determine what is the better buy.
Price of one 16 ounce bottle = $3.36
Price of two 10 ounce bottles = (2.30 × 2) - 0.4 = $4.2
Therefore, Darius will get the better deal buying one 16 ounce bottle.
[(upper legth + lower length) x height] divided by 2
Put the values of x to the equations of the functions:
1. f(9) → x = 9; f(x) = -3x + 10
f(9) = -3(9) + 10 = -27 + 10 = -17
2. f(-2) → x = -2; f(x) = 4x - 1
f(-2) = 4(-2) - 1 = -8 - 1 = -9
3. f(-5) → x = -5; f(x) = -2x + 8
f(-5) = -2(-5) + 8 = 10 + 8 = 18
Answer:
y=-x-2
Step-by-step explanation:
To find the slope of the line, you can use the slope formula. I did this with (-3,1) and (2,-4) to get: (1+4)/(-3-2). This ends up as -5/5, which simplifies to -1.
next I plugged in the slope and one point into the line equation: y=mx+b. I plugged in (-4)=(-1)(2)+b. This equated to b=-2.
