Factor the expression 12x - 9y + 15
Answer:
3(4x - 3y + 5)
Step-by-step explanation:
Since all coefficients are divisible by 3 (12/3 = 4, 9/3 = 3, 15/3 = 5):
3*4x - 3*3y + 3*5 = 3(4x - 3y + 5)

Pleaseee if you know this can you please answer I’m struggling really bad
Answer:
[tex]L_{1}[/tex] ⊥ [tex]L_{2}[/tex] ; [tex]L_{3}[/tex] ⊥ [tex]L_{2}[/tex] ; [tex]L_{1}[/tex] ║ [tex]L_{3}[/tex]
Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y = mx + b
"m" is slope
"b" is y-intercept (coordinates are (0, b)
Parallel lines have the same slopes and different y-intercepts.
Slopes of perpendicular lines are opposite reciprocals: [tex]m_{1}[/tex] × [tex]m_{2}[/tex] = - 1
~~~~~~~~~~~~~~~~~~~~~~
[tex]L_{1}[/tex] : y = x + 5 , [tex]m_{L_{1} }[/tex] = 1 , b = 5
[tex]L_{2}[/tex] : y = - x + 7 , [tex]m_{L_{2} }[/tex] = - 1 , b = 7
[tex]L_{1}[/tex] ⊥ [tex]L_{2}[/tex]
[tex]L_{3}[/tex] : [tex]m_{L_{3} }[/tex] = 1 , b = - 2
[tex]L_{1}[/tex] ║ [tex]L_{3}[/tex] and [tex]L_{2}[/tex] ⊥ [tex]L_{3}[/tex]

45/46
Answer:
Angle 1 is corresponding angle with Angle 7.Hope this will help you.
Answer:
Angle 1
Step-by-step explanation:
When two parallel lines are crossed by traversal line, the angles in matching corners are called corresponding angles
Angle 7 and angle 1 are corresponding
Give l m n find the value of x
Answer:
x=13
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
9x+17 + 3x+7 = 180
Combine like terms
12x +24 =180
Subtract 12 from each side
12x+24-24 =180-24
12x =156
Divide each side by 12
12x/12 =156/12
x=13

I have an old alarm clock, on which the hands move at only 95% of the speed that they should do.
I need it to wake me up at 7.30 am, so every night, at 10.30pm, I change the time shown on the
clock so that it will show the correct time at 7.30 am when the alarm goes off.
(a) What time does the clock show at 10.30 pm, immediately before I change it?
(b) What time do I change it to?
Please help immediately!!!
9514 1404 393
Answer:
a) 9:45 pm
b) 10:57 pm
Step-by-step explanation:
In the 15 hours between 7:30 am and 10:30 pm, the clock hands will have moved 15×0.95 = 14.25 hours = 14 hours and 15 minutes.
At 10:30 pm, the clock indicates 9:45 pm.
__
b) In the 9 hours between 10:30 pm and 7:30 am, the clock will have moved 9×0.95 = 8.55 hours, or 8 hours 33 minutes. That is, the clock needs to be set 27 minutes ahead of the actual time.
The clock need to be set to 10:57 pm.
_____
Alternate solution
At 95% speed, the clock loses 5%×60 minutes = 3 minutes each hour. In the 15 hours from morning to night, the clock will be 45 minutes slow. It will indicate 9:45 at 10:30 pm.
In the 9 hours from night to morning, the clock will lose 27 minutes so needs to be set 27 minutes fast. It should be set to 10:57 pm at 10:30 pm.

what is the total surface area of the rectangle prism? Help me please someone ASAP!
Answer:
B) 256
Step-by-step explanation:
w = 4
l = 12
h = 5
Formula:
SA = 2(wl + hl + hw)
SA = 2(4*12 + 5*12 + 5*4)
SA = 2(48 + 60 + 20)
SA = 2(128)
SA = 256

please help me with these two problems
Problem 1
With mean = median, the data set is symmetrical. Well it's more accurate to say "roughly symmetrical" due to the phrasing "mean is approximately equal to the median". Using the median as its center is fairly common with many distributions, so there isn't an issue here.
The error is from the phrasing "the quartiles should be used to measure the spread". The quartiles themselves don't measure spread. They are simply single data points and do not tell us the spread. If Ralph said Q3 = 75 is a measure of spread, then he would be incorrect. However, the difference between the third and first quartile will help get the IQR (interquartile range), as described by this equation below
IQR = Q3 - Q1
and this is one tool to measure how spread out data is. The larger the IQR is, the more spread out the data will be.
The IQR is how far of a gap it is from Q1 to Q3. Another tool to measure spread is the standard deviation. Ralph was probably thinking about the IQR when he mentioned the quartiles, but he should be more specific about what he means.
=======================================================
Problem 2
Answer: Skewed left
This is the same as saying "negatively skewed"
---------------
Explanation:
The main cluster of values is on the right side, while a small portion of values are to the left. We consider this the left tail and the left tail is pulled longer compared to the right tail. The further left we go, the shorter the bar and eventually we hit outliers. These much smaller outliers compared to the main cluster pull on the mean to make it smaller than it should be.
One example could be that this curve represents test scores. The majority of the class could get in the range of say 70 to 90. Then there's the unfortunate few outliers who scored much lower (possibly 40 through 60); those outlier scores pull down the mean grade of the class overall.
In short, negatively skewed data indicates that mean < median.
What is the answer to this question? The difference of x and 22 is equal to 8
Answer:
If the difference of x and 22=8
then equation is
X -22=8
X=22+8
X=30
therefore now we put the value of x in the equation
30-22=8
8=8
Answer:
x would be 30
Step-by-step explanation:
x-22=8
x=8+22
x=30
If 5 men can do a piece of work in 20 days, in how many days could 10 men
do the same work?
Answer:
10
Step-by-step explanation:
(U can do mental calculation and guess it will be 10 ..) or else ....
Constant(k) = xy
k= 5 x 20
k= 100
Constant(k) = xy
100 = xy
100 = 10y
y= 100/10 = 10
= 10
I hope im right!!
