1.) the relationship between y and 76 is that they are congruent; perpendicular to each other. They equal the same
y= 76
not sure abt the other one
Answer: f(x)=22
Explanation: 5(5)-3= 25-3=22
We substitute the x in the first problem with five because in the second equation, x is said to be five
80
8 x 10
2 x 4 x 5 x 2
2 x 2 x 2 x 2 x 5 <===
Answer:
8 ads
Step-by-step explanation:
To start off, we know we have a budget of $500 which means we cannot go above that amount. Ads cost $75 each but in our case they are now 20% cheaper. Lets figure out the new price of the ads. Remember to change 20% into its decimal form (20% -> 0.2)
75 x 0.2 = 15
Now we subtract 15 from 75 to get our new ad price.
75 - 15 = 60
Now to figure out how many ads we can get with a budget of $500, we simply divide 500 by 60. Don't forget to round the answer to the nearest whole number since we cannot go over our budget.
500 / 60 = 8 ads
the slopes of these lines are equal when the determinant of the coefficient matrix is zero. Thus, for homogeneous systems we have the following result: A nxn homogeneous system of linear equations has a unique solution (the trivial solution) if and only if its determinant is non-zero.
