(7x -7) + (6x +6) = 90
take away the parenthesis: 7x - 7 + 6x + 6 = 90
combine like terms: 13x - 1 = 90
add 1 to both sides: 13x = 91
divide both sides by 13: <span>x = 7.
Now: substitute x = 7 into the angles: the first angle is 42 degrees, the second angle is 48 degrees</span>
7.
irt = simple Interest we can fill in what we know so $500 * I * 20 = $250 than we solve for I so $250 / 500 = 0.5 than 0.5 / 20 = 0.025
8. Irt = simple interest fill it in 850 * I * 10 = $255 and then solve for I 255 / 850 = 0.3 than 0.3 / 10 = 0.03
9. Irt = simple interest 1200 * I * 15 = $720 and than solve for I so 720 / 1200 = 0.6 and then 0.6 / 15 = 0.04
Answer:
x=-6
y=-6
The slope is the line that goes on forever, the line isn't in any other area then the cordinites above.
Answer:
-15(7/20) = -307/20 = -15.35, which is less than -15.
