Mailboxes Plus sends packages overnight for $5 plus $0.25 per ounce. United Packages charges $2 plus $0.35 per ounce. Me. Molina
1 answer:
The package weighs 30 ounces.
Step-by-step explanation:
Mailbox Plus charges;
Charges per ounce = $0.25
Let,
x be the number of ounces.
M(x)=5+0.25x
United packges charges;
Charges per ounce = $0.35
U(x) = 2+0.35x
Cost will be same when the functions are equal;
M(x) = U(x)
Dividing both sides by 0.10
The package weighs 30 ounces.

Answer:
The statement that is true is:
A debt of $17 is a larger value than a debt of $20.
Step-by-step explanation:
Let us look at the statements one after the other to determine if they are true or not:
1) A debt of $17 is a larger value than a debt of $20: This is true because when measuring debts, we will consider the values in the negative sense (-). Therefore, a debt of $17 has a value of (-17) and a debt of $20 has a value of (-20). -17 is larger than - 20 on a number line, hence, a debt of $17 has a larger value for the debtor, than a debt of 20$
2) One half an apple is equivalent to 8 fourths apples:
one half an apple =
8 fourths of an apple = . Therefore, one half of an apple is not equivalent to 8 fourth of an apple.
3) 8.01 is a smaller increase in sales than 8.001: This statement is false because 8.001 is counted before 8.01, and the difference between 8.01 and 8.001 is:
8.01 - 8.001 = +0.009, hence, 8.01 is larger than 8.01 by a magnitude of 0.009
4) is a lower temperature than 6 below zero:
6 below zero = - 6°
On the number line, -6 is smaller than hence the statement is false.
Answer:
Yes, Cora is correct.
The equation of line with point (2,6) and slope of line (-1/3)
is x + 3y - 20 = 0
Step-by-step explanation:
Yes, the equation of a line can be written using a point and a slope of the line equation.
Cora has used the POINT SLOPE FORMULA, to represent the line equation.
In <u>Point Slope formula</u>:
The equation with slope m and points (x0,y0) can be written as:
(y-y0) =m (x-x0)
Here, the point (x0,y0) = (2,6)
and slope m = (-1/3)
So, the equation can be written as:
Hence, the equation of line with point (2,6) and slope of line (-1/3)
is x + 3y - 20 = 0
