Answer:
Both lines are perpendicular
Step-by-step explanation:
We want to determine the relationship between the two lines.
The best thing to do is to calculate the slope of the two lines;
Mathematically;
Slope = y2-y1/x2-x1
For PQ; slope will be;
(-3-17)/(1-(-4) =-20/5 = -4
For RS
slope = (4-3)/(-5-(-9)) = 1/4
Now we have -4 and 1/4 as slopes
The product of both is 1/4 * -4 = -1
When two lines are perpendicular, the product of their slopes is -1
We can conclude that both lines are perpendicular to one another
Answer: All real numbers
Step-by-step explanation:
You can take the cube root of positive and negative numbers, as well as zero.
Step-by-step explanation:
Simplifying 40 = 15 + -9x + -2
Reorder the terms: 40 = 15 + -2 + -9x
Combine like terms: 15 + -2 = 13 40 = 13 + -9x
Solving 40 = 13 + -9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9x' to each side of the equation. 40 + 9x = 13 + -9x + 9x
Combine like terms: -9x + 9x = 0 40 + 9x = 13 + 0 40 + 9x = 13
Add '-40' to each side of the equation. 40 + -40 + 9x = 13 + -40
Combine like terms: 40 + -40 = 0 0 + 9x = 13 + -40 9x = 13 + -40
Combine like terms: 13 + -40 = -27 9x = -27
Divide each side by '9'. x = -3
Simplifying x = -3
Hello!
First you have to add the number of fish
52 + 61 + 87 = 200
Then you find the percentage of grass carps
61/200 = 0.305
Then you multiply what you just got with the estimated sample
800 * 0.305 = 244
The answer is 244
Hope this helps!
