Answer:
Step-by-step explanation:
Option A
(-2)(-49)
=2×49
=98
Option B
(4)(-27)
=-108
Option C
(-7)(14)
=-98
Option D
(-9)(11)
=-99. As a result, there us only one correct option that equal -98 which is Option C. Hope it help!
The equation of the line is:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
Substituting values:
m = (8-4) / (6-2)
m = (4) / (4)
m = 1
Then, the equation is:
y-4 = 1 * (x-2)
Rewriting:
y = x-2 + 4
y = x + 2
The midpoint is:
k = ((x1 + x2) / 2, (y1 + y2) / 2)
k = ((2 + 6) / 2, (4 + 8) / 2)
k = ((8) / 2, (12) / 2)
k = (4, 6)
Then, the equation of the perpendicular line that passes through k is:
y = -x + b
Looking for b we have:
6 = -4 + b
b = 6 + 4
b = 10
Substituting:
y = -x + 10
Answer:
An equation of a line perpendicular to jl and passing through k is:
y = -x + 10
Answer:
Step-by-step explanation:
To find the amount deposited, we will simply use the formula for calculating simple interest.
Simple Interest = pxrxt/100 (fraction)
Where p = principal
R= Rate
T= Time
Principal is the initial amount deposited which we are ask to find.
R is given to be 6% and T is the time which is given in years
Simple interest is the interest earned over the year which is given to be $400
Lets substitute our variable into the equation
Simple Interest = pxrxt/100 (fraction)
$400 = P × 6 × 3 / 100
$400 = 18p/100 (fraction)
We will then cross multiply
$40 000 = 18 P
To get the value of P, we divide both-side of the equation by 18
4000/18 = 18p/18 (fractions)
$2222.22 = P
P = $2222.22
