Lm would be 78 because it is halfway between ab and dc and 98-58=40 and half of 40=20, so 58+20=78 or 98-20=78.
Question 4:
2x-3
Because we don’t know how much Fernando has that would be where we fill in the variable giving you 2x then 3 dollars less will give you the -3 therefore 2x-3
Question 5:
1/2x+7
Because we don’t know Deb’s age that would be the variable and we are looking for half of Deb’s age giving you 1/2x then the 7 years more giving you the +7 hence 1/2x+7
Given:
The length of the marathon is L= 46,145 yards.
The length covered by terrence is d = 23,561 yrads.
The objective is to find the remaining distance need to cover by terrence.
To calculate the remaining distance, we will use the relation,
On plugging the values in the above relation, we get,
Hence, Terrence needs to run about 23000 yards.
Let's see if this is better
1: Substitute 0 for x in the equation → y = f(0) = a^0 = 1
Therefore (0, 1) is a point on the graph
2: Substitute 1 for x in the equation → y = f(1) = a^1 = a
Therefore (1, a) is a point on the graph
3: y = f(x) = a^x is an exponential function which has a horizontal asymptote of y = 0 (equation for the x - axis) ... The reason it is above the x-axis is because there is no negative coefficient on "a" to reflect it below the x-axis
