No step-by-step explanation, nobody pays attention to them anyway.
Answer:
x=12, y=-3
Step-by-step explanation:
Plug (-4y) in for x in the top equation. The equation will now read 2(-4y) + 7y = 3. Distribute the 2 into the perenthecies getting: -8y+7y=3. -8+7 is -1 giving -y+3. Divide by -1 making y = -3. Plug -3 back into the top equation and solve for x: 2x + 7(-3)=3. 2x-21=3. 2x=24. x=12.
To find the unit price, divide the total price by the number of items. A unit price is a unit rate for one item.
1. 29.68 / 4 = 7.42
So $7.42 is the unit price.
2. 625 / 6 = 104 (rounded to the nearest whole number)
So Jess can type 104 words per minute.
Answer: (B) x^3
Explanation:
If you compare the graphs of
all on the interval -1 < x < 0, you'll find that y = x^3 is the smallest when x = -1
Squaring a negative number leads to a positive result, and similarly that happens with x^4 as well. This is because x^4 = (x^2)^2.
Plugging x = -1 into x^3 leads to y = -1 as a result.
