The Slope-intercept form of the equation of a line is given by:


y=mx+b \\ \\ where \ m \ is \ the \ slope \ and \ b \ is \ the \ y-intercept


There is a line that is perpendicular to the line we are looking for, so the slope is:

m_{1}=\frac{3}{4}


For two perpendicular lines it is true that:


m_{1}m_{2}=-1 \\ \\ \therefore \frac{3}{4}m_{2}=-1 \\ \\ \therefore m_{2}=-\frac{4}{3}


m_{2} is the slope of the line we are looking for.


Therefore we have that:


y=-\frac{4}{3}x+b \\ \\ For \ the \ point \ (-12,10) \\ \\ 10=-\frac{4}{3}(-12)+b \\ \\ \therefore b=-6


Finally, our line is:


\boxed{y=-\frac{4}{3}x-6}

svlad2 [7]

Answer:

The year is  b =  1995

Step-by-step explanation:

From the question we are told that

   The percentage of the number of babies born out of wedlock in 1990 is  k = 28%

    The percentage by which the number increase per year is  i = 0.6%

     The percentage of of the number of babies born out of wedlock considered is  a = 31%

Generally the difference in between the percentage in 1990 and the percentage considered is  

       d =  a - k

=>    d =  31 - 28

=>   d =  3\%

Generally the number of year require for the percentage to be equal  to  31%  is mathematically represented as

       n = \frac{3\%}{0.6\%}

=>     n = 5\ years

Generally the year which the considered percentage will be attained is  

    b =  1990 + n

=> b =  1990 + 5

=> b =  1995

Please help !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Morgarella [4.7K]

Answer:

60

Step-by-step explanation:

1, Extand line y for which y intercepts CB at point K

2, line y is a straight line and thus KAB=180-110=70

3, AY parallel to CX thus angle CKA=130 which is a alternative angle of BCX (if you can't see then try to extend CX as well

4,BKA=180-130=50 as BC is a straight line

5, the sum of interior angle of a triangle is 180, and we have KAB and BKA, thus angle ABC = 180-KAB-BKA=180-70-50=60
