What am i doing wrong? " write an equation of each line passing through the given pointers. give answers in standard form"a) (-1,2) and (5,7)the answer is 5x-6y=-17i just cant figure out where the negative in the 17 comes from. aside from that i have the right numbers. you!

Im afraid I cant make out the document bu this is how to  solve it:-

First find the slope of the line

slope = rise / run =  (7-2) / (5- - 1) = 5/6

Now use the point-slope form of equation of a straight line:-

y - y1 = m (x - x1)  where m= slope and (x1, y1) is a point on the line. Use the point (-1, 2):-

y - 2 = (5/6) (x + 1)

multiply through by 6:-

6y - 12 = 5(x + 1)

6y - 12 = 5x  + 5

-12 = 5x - 6y + 5

-17 =  5x - 6y

Flipping it over:-

5x - 6y = -17

5x - 6y = -37

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
