2y = -x + 3 or y = -1/2 x + 3/2
y = -5x - 1
where they intersect they are equal....so equate them
-1/2 x + 3/2 = -5x-1
4 1/2 x = - 5/2
x = -5/2 / 4 1/2 = -5/2 * 2/9 = -5/9 this is 'x' put this value in one of the equations to compute 'y'
If 5x - 17 = -x + 7 add 17 to both sides of the 'quation
5x = -x + 7 + 17 add 'x' to both sides
6x = 24 divide both sides by 6
x = 4
Hit the 2nd button upper left....then the cos button turns into 'acos' which is inverse cosine
Area of a triangle = 1/2 b * h b = base =20 ft h = height = 16 ft
W = .2 B
W/.2 = B
or B = 5W 5 is 500% this situation comes up often when dealing with % on this forum
while Boss's salary is 500% of Werner's it would take a 400% INCREASE from his present salary to match B
i.e. W + 400% * W = B
5W = B
3(y+41)=3y+123
3y + 123 = 3y + 123 ANY value of y will be a 'solution' .... infinite answers
[ (2y+1)(y+2)][ 1/(y+2) - 4/(2y+1) + (3y-4)/(2y^2+5y+2)] =
2y+1 - 4y-8 + 3y-4 = 0
y -11=0
y=11
Similar to the ship question above in the forum listing: d = 50 t
the ship travels 25 miles (d) each hour (t)
d = 25 t or t = d/25 Cannot really give you a hint.....so there is the answer
