so x^2+ 2x -9 = (-4)^2 + 2*(-4) - 9
= 16 - 8-9
= 8-9
= -1

Answer:
x = 15
Step-by-step explanation:
For the lines to be parallel , then
∠ MYX = ∠ PXW = 11x - 25 ( corresponding angles ) , so
∠ ∠ MYX = ∠ ZYN ( vertical angles ) , substitute values
11x - 25 = 7x + 35 ( subtract 7x from both sides )
4x - 25 = 35 ( add 25 to both sides )
4x = 60 ( divide both sides by 4 )
x = 15

Dominic wants to test if one of two types of fertilizer (a standard fertilizer and a new product) is better for producing melons of equal weight after a three-month fertilization program. Dominic has two identical land plots (1 and 2) and is considering how to assign 30 melon plants, each of which has a numbered tag, to the fertilizer. What is the best way to do this as a matched-pairs design?
A. Put all the odd-numbered melons in plot 1 and the even-numbered melons in plot 2. Then give the standard fertilizer to plot 1 and the new product to plot 2.
B. Assign the melons completely at random to the two plots using a coin flip, heads meaning plot 1 and tails meaning plot 2. Then give the standard fertilizer to plot 1 and the new product to plot 2.
C. Obtain pairs of melon plants whose seedling heights are roughly equal at the start of the experiment and randomly assign one of the pair to plot 1 and the other to plot 2. Then give the standard fertilizer to plot 1 and the new product to plot 2.
D. Obtain pairs of melon plants whose seedling heights are roughly equal at the start of the experiment and put the taller of each pair into plot 2. Then give the standard fertilizer to plot 1 and the new product to plot 2.
E. Divide the 30 melon plants into two groups, with the 15 tallest seedlings in one group. Randomly choose which plot to assign the tallest plants and assign the smallest plants to the other plot. Then give the standard fertilizer to plot 1 and the new product to plot 2.
Answer:
C
Step-by-step explanation:
A. is wrong because having a different height for each seedling and not trying to keep it equal is simply worse than making sure the heights are identical.
B. Completely wrong because it would likely result in 1 plot having more melon seedlings than the other.
C. Correct because it makes sure the seedlings are the same height at the beginning of the experiment, allowing less randomness in the experiment.
D. Putting the taller of a each pair for 1 plot makes it the experiment rigged in favor of the plot with taller seedlings
E. Same issue as D.
Lexi took 15 shots on goal during the Columbus Day tournament, and she made 20% of them. How many goals did Lexi score?
Answer:
3
Step-by-step explanation:
First, you have to turn the percent into a decimal. Which would give you 0.20. Then multiple 15 by 0.20. Which gives you 3.

What is the slope of the line y+3=2(x-2) PLEASE SHOW WORK
Answer:
2
Step-by-step explanation:
Put the equation into y = mx + b form, where m is the slope of the line
Distribute 2 to the parentheses:
y + 3 = 2(x - 2)
y + 3 = 2x - 4
Subtract 3 from both sides:
y = 2x - 7
So, the slope is 2.

Puzzle Details
Elevator Mishap
Six people, whose names are Fred Alberts, Larry Smith, Brian Martin, Marty Jones, Bill Edison, and John Fox were in an elevator together.
Suddenly, the lights went out. When the lights came back on, Fred Alberts' wallet was missing.
Detectives have investigated. They have questioned the suspects, the witnesses, and people who know the suspects. They have collected physical evidence (hair samples, fibre samples, etc.) from the crime scene. They have collected 14 clues, but have not been able to solve the crime.
Therefore, they have called in the world's greatest detective, YOU. You must now examine the clues and solve the crime.
No two suspects have the same weight, colour shoes, colour umbrella, colour car, or hair colour.
The suspect who owns a purple car was wearing tan shoes.
The suspect who weighs 180 pounds owns a green car.
Brian Martin owns a green car.
The suspect who owns a black car was wearing blue shoes.
The suspect who weighs 150 pounds was wearing tan shoes.
Marty Jones was carrying a purple umbrella.
John Fox has red hair.
Larry Smith weighs 210 pounds.
The suspect who weighs 190 pounds was wearing blue shoes.
The suspect who was carrying a red umbrella is not the one who was wearing black shoes.
The thief owns a black car.
The suspect who owns a white car is not the one who weighs 170 pounds.
Bill Edison was wearing brown shoes.
The suspect who weighs 190 pounds is not the one who has red hair.
Answer:
Marty Jones
Explanation:
Given that no two suspects have the same weight, colour shoes, colour umbrella, colour car, or hair colour.
There are six people in the elevator including Fred Albert. Fred Albert was the one whose wallet was stolen and so our suspects are the other five people in the elevator.
We know that the thief owns a black car and he was wearing blue shoes
( since the suspect who owns a black car was wearing blue shoes). The thief also weighs 190 pounds( since the suspect who weighs 190 pounds was wearing blue shoes)
Brian Martin has a green car so he is cancelled out
John Fox has red hair and is cancelled out(since the suspect who weighs 190 pounds is not the one who has red hair)
Bill Edison was wearing brown shoes so he is cancelled out(since thief was wearing blue shoes)
Larry Smith weighs 210 pounds and he is cancelled out( since thief weighs 190 pounds)
We are left with one suspect remaining Marty Jones, hence he is the thief

What is Tax?A tax is a mandatory financial charge or other kind of levy placed on a taxpayer by a government agency to pay for government expenses and other public expenditures.
Given:
Sales tax in his city is 8%.
let the price be x.
x( 1+ 8%) ≤ 20
1.08x ≤ 20
x≤ 18.52
So, x can be 18.52 of less than 18.52.

7(1+5m)+2m=7+2m
explain step by step plz
Answer:
m = 0
Step-by-step explanation:
distribute
7 + 35m + 2m = 7 +2m
add 35m + 2m
7 + 37m = 7 + 2m
subtract 2 from 37m
7 + 35m = 7
subtract 7 from 7
35m = 0
0 ÷ 35 = 0
so technically the answer is 0
