Answer:
Any negative integer and any positive integer.
Like -5 and 3.
Step-by-step explanation:
In multiplication, <u>a positive number and a negative number will result in a negative product</u>.

There is no solution for the first one
if you eliminate y you get 2 equations
-13x - 13z = -25
-13x - 13x = -15
- there is no solution to theses
a23 means the element in the second row and the 3rd column
so its -5
Answer:
A four mile ride would cost $10
Step-by-step explanation:
Let T be the total ride cost
Let M be the amount of miles driven
T = 1.75M + 3
You can now sub in any distance in miles into the equation, but for this instance lets sub in 4 miles
T = 1.75*(4) + 3
T = 7 + 3
T = 10
Therefore, a four mile ride would cost 10 dollars
The difference of the given functions is x^2 + 10
<h3>Difference of functions</h3>
Given the following functions
f(x) = 2x^2 + 3 and
g(x)=x^2-7
Take the difference
(f-g)(x) = 2x^2 + 3 - (x^2 - 7)
(f-g)(x) = 2x^2 - x^2 +3 + 7
(f-g)(x) = x^2 + 10
Hence the difference of the given functions is x^2 + 10
