300
Step-by-step explanation:
3x = 150
6x = z
Z=6x*150/3=300
Answer:
y = 2/3 x - 2.
Step-by-step explanation:
The slope of the line = rise/run = 2/3 and the y-intercept is at y = -2.
The equation is y = mx + c where the slope m = 2/3 and c = -2.
A= 9 b= 224
Just add them to find ur anwser make sure to get these
I'd suggest you get rid of the fraction first. Mult. every term by 3. You will get
3y^2 + 10y + 3 = 0
From inspection, with coefficient a=3 and coeff. c = 3, the binomial factors could possibly begin with y or 3y: for example, y+1; also, the binom. factors may end in +1. Let's try the possible binomial factor 3y + 1.
Note that 10y separates into 9y+1y.
Then 3y^2 + 10y + 3 = 0 becomes
3y^2 + 9y + 1y + 3 = 0
Let's apply factoring by grouping:
3y^2 + 9y + 1y + 3 = 0
3y*(y + 3) + 1(y + 3) so y+3 is indeed a common factor.
Factoring y+3 out, we get (y+3)(3y + 1), which prove to be the correct set of factors. Multiply these together to ensure that the product is indeed y^2 + (10/3)y + 1.
