Simplifying 3(5 + -1e) + 2 = 10 (5 * 3 + -1e * 3) + 2 = 10 (15 + -3e) + 2 = 10 Reorder the terms: 15 + 2 + -3e = 10 Combine like terms: 15 + 2 = 17 17 + -3e = 10 Solving 17 + -3e = 10 Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right. Add '-17' to each side of the equation. 17 + -17 + -3e = 10 + -17 Combine like terms: 17 + -17 = 0 0 + -3e = 10 + -17 -3e = 10 + -17 Combine like terms: 10 + -17 = -7 -3e = -7 Divide each side by '-3'. e = 2.333333333 Simplifying e = 2.333333333

Find the possible value or values of y in the quadratic equation 4 – 4y – y 2 = 0. A. y = –3, y = –1 B. y = 2 C. y = –2 + 2√ 2,

xz_007 [3.2K]

4 - 4y - y² = 0
-y² - 4y + 4 = 0
y = -(-4) ± √((-4)² - 4(4)(-1))
2(-1)
y = 4 ± √(16 + 16)
-2
y = 4 ± √(32)
-2
y = 4 ± 4√(2)
-2
y = 4 + 4√(2) or y = 4 - 4√(2)
-2 -2
y = -2 - 2√(2) or y = -2 + 2√(2)

The answer is C.

At the grocery store, Lily spent m dollars on milk, twice that amount on fruit, and 6 dollars less than 3 times the amount spent

AlladinOne [14]

Answer:

The amount of money Lily had when she left the store, in terms of m, is 86 - 6m

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

m = Milk Lily purchased

2m = Fruit Lily purchased (twice that amount on fruit)

3m - 6 = Bread Lily purchased (6 dollars less than 3 times the amount spent on milk for bread)

Amount of money Lily entered = $ 80

2. How much money did Lily have when she left? Write your answer in terms of m.

Let's write the equation to find out the money left in terms of m, this way:

Money left = 80 - m - 2m - (3m - 6)

Money left = 80 - m - 2m - 3m + 6

Money left = 86 - 6m

The amount of money Lily had when she left the store, in terms of m, is 86 - 6m
