Drag and drop each pair of lines into the correct category to indicate whether the pair of lines are parallel, perpendicular, or neither.
Answer:
Step-by-step explanation:
to know:
-to be paralel the lines have to have the same slope
-to be perpendicular the slope has to be negative invers of thhe other
-to be neither has to be none of the above two
equation to compare to is
y=mx+b where m is the slope
if your equation does not have this form make it have this form
2y=3x+1 so divide by 2
y=[tex]\frac{3}{2}[/tex] x+1 so here the slope is [tex]\frac{3}{2}[/tex]
4x+6y=14 so subtract 4x and then divide by 6 to isolate y
6y= -4x+14
y=[tex]\frac{-4}{6}[/tex] x + [tex]\frac{14}{6}[/tex] symplify
y=[tex]\frac{-2}{3}[/tex] x + [tex]\frac{7}{3}[/tex] so the slope here is [tex]\frac{-2}{3}[/tex]
So if you compare the slopes you can see that are negative reciprocal of eachother so the lines are perpendicular
and so on...

What are the x intrcepts?
Equation= y=x^2-9x+20. (Factored its (x-4)(x-5)
What is the Y intercept? Hint: use the equation y=x^2-9x+20
Answer:
x intercept (4,0) and (5,0)
y intercept (0,20)
Answer:
y- intercept = 20
Step-by-step explanation:
Given
y = x² - 9x + 20
To find the y- intercept let x = 0 in the equation, that is
y = 0² - 9(0) + 20
= 0 - 0 + 20 = 20 ← y- intercept or (0, 20) in coordinate form

Answer:
8 workers
Step-by-step explanation:
This a ratio type of question, you want to identify the similarities between 6 workers and 3 days. Ignore the 8 hours part, it's to mess with you!
6=The amount of workers
3=The amount of days it took them to complete a wall
6/3=2
So by increasing the amount of workers by to you'll get 8 workers.

Matthew is paid $8.50 for each acre he mows on his grandparent's estate. He mows 50% of an acre in 3/5 of an hour.
Question
At the rate, how much will Mathew be paid for two hours of moving? Round to the nearest cent.
Answer:
exact answer =$19.83
rounded answer = $20
Step-by-step explanation:
3/5 = 0.6, so in 0.6 hours he can do 50% so in 2 hours that has 3 0.6 so 150% and the remaining time is 0.2 hours thats 1/3 of 0.6 so just divide 50% by 3 you'll get around 16.7% so in 2 hours he finished 166.7%
16.7% = 1/3 of 50% = 8.50 = 8.50/3 = 2.83
so 8.50 + 8.50 + 2.83 =
$19.83

What is the equation of the line in slope-intercept form that passes through the point (-9, 3) and has a slope of 2/3?
Answer:
y= -2/3x-3
Step-by-step explanation:
The formula for slope-intercept form is y=mx+b. m=Slope. b=y-intercept. Therefore the equation would be y= -2/3x-3
Answer:
y=2/3x + 9

A set of average city temperatures in May are normally distributed with a mean of 20.66 degrees and a standard deviation of 2 degrees. The average temperature of Singapore is 26 degrees
Answer:
0.9962
Step-by-step explanation:
The objective of this question is to determine the proportion of average city temperature that is lower than that of Singapore.
Suppose X is a random variable that follows a normal distribution:
Then;
[tex]X \sim N ( \mu = 20.66, \sigma = 2)[/tex]
[tex]P(X< 26) = P \bigg ( Z < \dfrac{26 - 20.66}{2} \bigg)[/tex]
[tex]P(X< 26) = P \bigg ( Z < \dfrac{5.34}{2} \bigg)[/tex]
[tex]P(X< 26) = P \bigg ( Z < 2.67\bigg)[/tex]
From the z tables;
P(X< 26) = 0.9962
Thus, there is 0.9962 proportion of average city temperature are lower than that of Singapore.
Answer:
0.9962
Step-by-step explanation:
A set of average city temperatures in May are normally distributed with a mean of 20.66 degrees and a standard deviation of 2 degrees. The average temperature of Singapore is 26 degrees
What proportion of average city temperatures are lower than that of Singapore?
Solution:
The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation[/tex]
Given that μ = 20.66, σ = $2
For the average temperature of Singapore of 26°, the z score is:
[tex]z=\frac{x-\mu}{\sigma}=\frac{26-20.66}{2} =2.67[/tex]
From the normal distribution table, P(x < 26) = P(z < 2.67) = 0.9962
