1) Create was we already know in the equation. 16=-7(-3)+b. (This is using the initial equation of y=mx+b.)
2) Simplify and solve for b: 16=21+b = -5=b
3) Replug your be value into your equation: y=-7x-5.
Answer
y=-7x-5
Words: y equals negative seven x, minus five.
You have to use the distributive property, therefore you get 2x+13/3.
The next step is to do 2 x 5 because they gave us a number for the variable x. Then you have to do 2 x 13 which gives us 26.
10+26=36 and 36/3=12, hope I helped, Have a nice day! :)
Answer:
x = 3
Step-by-step explanation:
Using the rules of logarithms
ln x = ln y ⇒ x = y
ln e = 1
Given
2 ln e ln 5x = 2 ln 15 ( divide both sides by 2 )
ln e ln 5x = ln 15
ln 5x = ln 15, hence
5x = 15 ( divide both sides by 5 )
x = 3
Answer:
No.
Step-by-step explanation:
No because if we substitute the given values into the equation they do not fit:
y = 7x
x = 1 and y = 4:
Left side = 4
right side = 7*1 = 7.
