1. 20 x 8 = 160 m
2.
January to November = 11 months.
11 flats are painted every year.
100 flats / 11 flats per year = 9 years + 1 month
the next time it will be painted is September 2019.
Answer:
undefined
The problem:
Find the slope for the line going through (3,4) and (3,-4).
Step-by-step explanation:
Line up points vertically and subtract.
Then put 2nd difference over 1st.
( 3 , 4)
-(3 , -4)
------------
0 8
So the slope would have been 8/0 but this is undefined.
So the slope is undefined.
Also notice the x's are the same and the y's are difference so this is a vertical line. There is only rise in a vertical line and no run. Recall, slope is rise/run. You cannot divide by 0 so this is why we say the slope is undefined when the x's are always the same no matter the y.
Answer:
X=3
Step-by-step explanation:
2(4x-3)-t=4+2x
multiply parentheses by 2
8x-6-8=4+2x
Calculate
8x-14=4+2x
Move terms
8x-2x=4+14
Calculate the sum after collecting like terms
6x=18
Divide both sides by 6
x=3
27 is the answer, I can explain how I got that if you need.
