Answer:
-1
Step-by-step explanation:
can you also hep me on something
9(n+3)=7n-3
1) distribute 9 into (n+3)
9n+27=7n-3
2) subtract 7n on both sides
2n+27=-3
3) subtract 27 on both sides
2n=-30
4) divide by 2
n=-15
Answer:
Grayson has to walk 1.7 miles across the field.
Step-by-step explanation:
We have drawn the diagram for your reference.
Given:
Grayson usually walks 1.5 miles west on the side walks
According to Diagram we can say;
CA = 1.5 miles
Also Given:
Grayson also walks 0.8 miles north on the sidewalks
So According to Diagram we can say;
BA =0.8 miles
Now we need to find number of miles Grayson have to walk across the field.
According to diagram we can say;
We have to find CA.
Assuming the diagram to be right angled triangle.
We can find CA using Pythagoras theorem.
Substituting the given values we get;
Taking square root on both side we get;
Hence Grayson has to walk 1.7 miles across the field.
Answer:
production cost f(x), in dollars, for x number of units produced by company 1:
f(x) = 0.05x^2 − 7x + 300
2) Table that represents the production cost g(x), in dollars, for x number of units produced by company 2:
x g(x)
0.6 899.58
0.8 899.52
1 899.50
1.2 899.52
1.4 899.58
3) Comparison: do a table for f(x) with the same x-values of the table for g(x).
x f(x) = 0.05x^2 − 7x + 300 g(x)
0.6 295.818 899.58
0.8 294.432 899.52
1 293.05 899.50
1.2 291.672 899.52
1.4 290.298 899.58
As you can see the values of f(x) are consistently lower than the values of g(x) for the same x-values.
The minimum production cost for company 2 is around 899.50 at x = 1, while the minimum production cost of company 1 is defintely lower (lower than 292.298 for sure, in fact if you find the vertex it is 55).
Answer: Based on the given information, the minimum production cost for company 2 is greater.

Step-by-step explanation:
3y = -9
Divide each side by 3
3y/3 = -9/3
y = -3
