Write an equation of the line that passes through (1,-3) and is perpendicular to the line <img src="https://tex.z-dn.net/?f=y%3D
Lubov Fominskaja [6]

Answer:

y = 3x

Step-by-step explanation:

Given line slope = m = -1/3

   perpendicular line slope = - 1/m = 3

Point slope form through point 1, - 3

(y+3) = 3 ( x-1)       expand and rearrange

y -3 = 3x- 3

  y = 3x - 6

$2,500 for 25 years at<br> 2.75% annual simple<br> interest
xxMikexx [17]

Answer:

4,218.75

Step-by-step explanation:

Lets say that P is your starting principal (spelled -pal and not -ple, because Your Money is Your Pal), r is the interest rate (expressed as a decimal), and Y is the number of years you invest. Then your future value will be:

P (1 + rY) (Simple Interest)

P (1 + r)Y (Annually Compounded Interest)

Note the two formulas give the same answer for one year. After that, compound interest takes off.

7x²=9+x
so
for
0=ax²+bx+c

x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}
so

7x²=9+x
mins 9 from both sides and minus x
7x²-1x-9=0
a=7
b=-1
c=-9


x=\frac{-(-1)+/-\sqrt{(-1)^2-4(7)(-9)}}{2(7)}
x=\frac{1+/-\sqrt{(-1)^2+4(7)(9)}}{2(7)}
so the 4th one

Line m passes through C(-2, 0) and D(1, -3). What is the equation of the line m in standard form?
Serga [27]
From general equation of a line;
y=mx+c
m=\frac{change in y}{change in x}
m=\frac{0--3}{-2-1}
m=-1
y=-x+c 
Finding value of c;
using point (-2,0)
0=-(-2)+c
c=-2
y=-x-2
