Answer:NUMERATORS
Step-by-step explanation:
Answer:
y=-9x-4
Step-by-step explanation:
Perpendicular lines meet the following condition:
m2*m1= -1 (a)
where m is the slope of a line
m1 is given through equation of line 1, y =1/9 x+2
m2 must be -9 -> from eq. (a)
The Line has the following equation: y=mx+b, where m=-9 and the b is the interception with y axis.
Evaluating the above equation in (-1,5) we have the following equation
5= -9*(-1)+b, we have b=-4
The line has the following equation
y=-9x-4
Slope intercept form
Answer:
P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Step-by-step explanation:
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
Answer:
X=-5
x=-7
Y=12
Step-by-step explanation:
Answer:
x=16
Step-by-step explanation:
We can use ratios to solve
8 11
---- = -----------
x 6+x
Using cross products
8(6+x) = 11x
Distribute
48 +8x = 11x
Subtract 8x from each side
48 = 11x-8x
48 = 3x
Divide by 3
48/3 = 3x/3
16=x
