It’s a graph that provides information
Answer and explanation:
This is an example of negative correlation/inverse relationship between two variables. A negative correlation between two variables, independent and dependent variable, occurs when increase in one variable is associated with decrease in the other. In other words, the two variables tend to go in opposite direction.
The independent variable is the variable that causes a change in the dependent variable. For example, an increase in the independent variable in an inverse relationship will bring about a decrease in the dependent variable.
A good real world example is the increase in inflation and the decrease in purchasing power of money.
An equation for this could be
Y=-0.2(x)
Where y is dependent variable purchasing power and x is independent variable inflation
I use my calculator
Y1 (the blue one) = x^2-2x
Graph
2nd trace minimum
X= 1 and y = -1
So the vertex is (1,-1)
Answer:
I think is A
Step-by-step explanation:
-7x -13 ≥ 8
+13 +13
-7x ≥ 21 (then, divide by -7 and when u divide by a negative number, the sign flip)
Answer: x ≤ -3
