Step-by-step explanation:
(12, -11) represents (x, y)
so 12 is x
-11 is y
now we need to do
x-9 and y+9
x-9=
12 - 9 = ???
y+9=
-11 + 9 = ???
then put into formate (x, y) as before
if you need more help comment and please put as brainiest
Answer:
Component Form: v = <-1,6>
Magnitude of v: ||v|| = √37
Direction of v: θv = 100° (to the nearest degree)
Step-by-step explanation:
Component Form: v = <(5-6),(3-(-3))> = <-1,6>
Magnitude of v: ||v|| = √[(-1)²+(6)²] = √(1+36) = √37
Direction of v: α = tan⁻¹|6/-1| = tan⁻¹|-6| = tan⁻¹(6) = 80.53° which is your reference angle, but to verify that the angle is in the second quadrant, you'll need to do θv = 180° - 80.53° = 99.47°, therefore your direction angle is θv=100° to the nearest degree.
Answer:
Pat would be 32 and Patrick will be 9 before the 5 years
Step-by-step explanation:
pat is older by 23
in 5 years the dad will be 28 years older than his son and 28 x 1/2 = 14
so the son will be 14 in 5 years so he would be 9 now making the dad 23 years older the dad would be 32
Answer:
The solution of the two give equations is (-1,4)
Step-by-step explanation:
i) First equation is y = -x + 3
ii) Second equation is y = x + 5
iii) If we add the two equations we get 2y = 8 ∴ y = 4
iv) Substituting the value of y obtained in iii) in equation i) we get
4 = -x + 3 ∴ -x = 4 - 3 ∴ -x = 1 ∴ x = -1
v) substituting x = -1 and y = 4 in the second equation we see that the equation is satisfied.
Answer:
C. X=27
Step-by-step explanation:
-11+1/3x+9=7
1/3x=7+11-9
1/3x=9
x=9x3
x=27
