Step-by-step explanation:
hope u enjoy!!! add me in the brainly list
5x-9 = 3x+3
2x-9 = 3
2x = 12
x= 6
plz mark branliest, hopoe this helps :)
Answer:
y = 189.8
Step-by-step explanation:
Apply trigonometric function to find y.
Reference angle (θ) = 50°
Adjacent side = 122
Hypotenuse = y
Apply CAH, since the Hypotenuse and the Adjacent are involved.
Thus:
Cos θ = Adj/Hypo
Plug in the values
Cos 50° = 122/y
y*Cos 50° = 122
y = 122/cos 50°
y = 189.8 (beater tenth)
1,110,000.
You look at the ten thousands value and look at the number after it. If it is less than 5 then it is that number, just add zeros to the rest of the values after it.
Answer: (in point slope form as asked)
9: y-1=3(x-0)
10: y+3=-1(x-2)
Why?
Point slope equation: y-y1=m(x-x1)
M=slope
Y1= y for first point
X1= x for first point
9: First I found the slope but moving up 3 over 1 from point 0,1 up to point 1,4 because slope = rise/run this gave me 3.
10: I started at point 2,-3 and moved up to point 1,-2 which shows that the slope is 1, BUT it is a negative line so it’s a -1. Then because the equation for point slope is subtraction and -3 is negative it becomes addition
Hope this helps :D (comment if you need me to explain better)
