2 answers:
Answer: 80 pounds
Step-by-step explanation:
Let x be the amount of cashews needed to make a 400 pound cashew and peanut mix.
Then the amount of peanuts= 400-x
Now, the price of cashews before mix = 13x
the price of peanuts before mix = 8(400-x)
the price of 400 pound mix = $9(400)=$3600
According to the question:
Hence, he use 80 pounds of cashews .

Given:
A table of values of a linear function.
To find:
The slope, y-intercept and equation of the function.
Solution:
Take any two points on the table.
Let the points are (-1, -3) and (0, -6).
Slope of the line:
m = -3
Slope of the function = -3
y-intercept of the function is the point where x = 0.
In the table y = -6 when x = 0
y-intercept = -6
Equation of a line:
y = mx + c
where m is the slope and c is the y-intercept
y = -3x + (-6)
y = -3x - 6
Equation of a function is y = -3x - 6.
