(Please help I suck at geometry!) Write an equation of a line perpendicular to line AB below in slope-intercept form that passes
solmaris [256]

Answer:

y = 1/2x + 5/2

P.S, this isn't geometry really. It's more like algebra :)

Step-by-step explanation:

Step 1: Find equation of line AB

m = (5 - 1)/(-2 - 0)

m = 4/-2

m = -2

y = -2x + 1

Step 2: Find slope of perpendicular line

<em>Take the negative reciprocal of line AB</em>

m = 1/2

y = 1/2x + b

Step 3: Find <em>b</em>

6 = 1/2(7) + b

6 = 7/2 + b

b = 5/2

Step 4: Rewrite perpendicular equation

y = 1/2x + 5/2

or

y = 0.5x + 2.5

My mom walks 1 mile in 14<br> minutes. If she walked for 56<br> minutes, how far did she walk?
marysya [2.9K]

Answer:

4 miles

Step-by-step explanation

If your mom can walk 1 mile in 14 minutes then 2 miles would take her 28 minutes 3 miles would take her 42 minutes and finally if she walked 4 miles it would take her 56 minutes.

14 + 14 + 14 + 14 = 56

14 x 4 = 56

X^6+3x^3-5 <br> write the expression in quadratic form
Art [367]

Step-by-step explanation:

v =  {x}^{3}  \\  {v}^{2}  + 3v - 5 = 0 \\

Solving this equation using the quadratic formula, we get two real solutions :

1.1926 or -4.1926

Now we know the values of v , we can calculate x since x is ∛ v

{x}^{6}  + 3 {x}^{3}  - 5 = 0

x =  \sqrt[3]{1.1926}  = 1.0605 \\ x =  \sqrt[3]{ - 4.1926}  =  - 1.6125
