D)
Because Mexico borders the US, but it does not border Canada. The conditional is false.
Answer:
B
Step-by-step explanation:
A proportional relationship is represented by linear function with its linear parameter "b" equal to zero. Since b is equal to zero, the line passes through the origin and the function/relation is proportional.
To verify that we divide the y coordinate over the x coordinate we obtain a constant called k, which is the slope.
For instance:

According to this function we can easily check a proportional relationship among its points:


Answer:
4 rolls
Step-by-step explanation:
We can use logic to find how many rolls of toilet paper you would need.
If you use 10 sheets of toilet paper every time you use the toilet, and this happens 3 times a day, then each person per day uses
sheets of toilet paper per day.
For a 4 family household with 4 people, that would be
sheets every day for the whole family.
For a week (7 days) the whole family would use
sheets per week.
If rolls of toilet paper are shipped by every 250 sheets, then we'd need
rolls.
We can't have 0.36 of a roll, so we round up to 4 so we have enough.
Hope this helped!
The expression 6x^2 will have the shape of a parabola when graphed
<h3>What are quadratic equations?</h3>
Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
<h3>How to determine the shape of 6x^2 when it is graphed?</h3>
The function expression is given as:
6x^2
Express the function as an equation.
So, we have
y = 6x^2
The above equation is a parabola or a quadratic equation.
All quadratic equations have the same shape and the shape is parabola
This means that the expression 6x^2 will have the shape of a parabola when graphed
Hence, the expression 6x^2 will have the shape of a parabola when graphed

Esa expresión es una simple suma, un número negativo más uno positivo ejemplo: le debes 3 dólares a tu hermano lo cual es negativo, pero tu padre te regala 4 dólares lo cual es una valor positivo porque lo tienes en tus manos, pagas los 3 que debes y te sobra un dólar de los 4 que tenias, ahora ya no debes nada y aún te sobra un dólar.
