The equivalent value of the function f(x) = –2x^2 – 3x + 5 if x = -3 is -4
We are to evaluate the function f(x) = –2x2 – 3x + 5 for the input value –3.
Given the function:
For x = -3, we will have to substitute x = -3 into the expression to have:
f(-3) = –2(-3)^2 – 3(-3) + 5
f(-3) = -2(9) + 9 + 5
f(-3) = -18 + 14
f(-3) = -4
Hence the equivalent value of the function f(x) = –2x^2 – 3x + 5 if x = -3 is -4

Answer: Her total distance was greater this week.
Step-by-step explanation:
Carol jogged 1 3/4 miles on 5 days last week. Converting 1 3/4 miles to decimal, it becomes 1.75 miles. The total number of miles that she jogged last week is
5 × 1.75 = 8.75 miles
She jogged 2 1/4 miles on 4 days this week. Converting 2 1/4 miles to decimal, it becomes 2.25 miles. The total number of miles that she jogged this week is
4 × 2.25 = 9 miles
Since 9 miles is greater than 8 miles, then her total distance was greater this week.
We are given the length of two segments:
WZ = 32
YZ = 6
and we are told that x is the midpoint of the segment WY
We are asked to find the length of the segment WX
Notice that the total length of the segment WZ is 32. from the point Y to the point Z we have 6 units. therefore, between W and Y there is 32 - 6 = 26 units.
SInce X is the midpoint of the distance between W and Y, then it has to cut the segment WY (26 units long) in two equal parts, each of length 13 units (half of 26).
Therefore, WX must be of length 13 units.
