Let x = green pepper plants
2x = red pepper plants
2x + x = 12
3x = 12
x = 12/3
x = 4
Answer:
1.25 OR 1 1/4
Step-by-step explanation:
Answer:
The answer is: 5(x+8)(-x+1)
Step-by-step explanation:
To factorize, you can take the FACTORS of 5x^2 and 8. Once you factor them, multiply them cross ways, like CROSS MULTIPLICATION. Moreover, if you do this and get -3x, then you have the factorization. For example
-5x^2 -3x + 8
5x 8
-x 1
Then cross multiply to get: -8x + 5x= -3x (this is correct)
Now you can find the factorization by just going across: (5x+8)(-x+1)
It is basically guess and check.
Since it was stated that the equation is linear, therefore
we can use the slope point formula to find for the slope and intercepts. The
linear equation has a form of:
y = mx + b
where y is the retail price, x the wholesale price, m the
slope and b the y-intercept
m = (y2 – y1) / (x2 – x1)
m = (238 – 112) / (175 – 85)
m = 1.4
So the equation now becomes:
y = 1.4x + b
Plugging in any pair to find for b:
112 = 1.4(85) + b
b = -7
So the full equation is:
<span>y = 1.4x - 7</span>
<span>or</span>
<span>R = 1.4C - 7</span>
