Answer:
The answer is below
Step-by-step explanation:
A linear function graph can be represented by:
y = mx + b; where m is the slope and b is the y intercept, x is the independent variable and y is the dependent variable.
a) From the graph we can see the graph passes through the point (0, 100) and (20, 400). Hence we can use the following formula to find the equation:

b) An example of real life linear function is the energy consumed per day in kWh. Let us assume 5 kWh is consumed each day by the person. Since the independent variable is the days, it would be on the x axis, while the dependent variable (energy consumed) would be on the y axis.

To solve the problem find the value of (45)^2 at first


The answer is 25 with the remainder 75

You can simplify the fraction to be 25/26
Answer: option c or 3 because you gotta take out the 6 so u do -6 which left is negative and right is positive and then get rid of the +2 exponent so up is positive and down is negative so you move -2 which is down.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
this equation is in the form of ax^2+bx+c
so a is 4, b is -9, and c is 8
