Answer:
b) -10
Step-by-step explanation:
x^2 + 3x + k = (x - 2)(x - a)
(x - 2)(x - a) = x^2 - 2x - ax + 2a = x^2 + [-2 - a)x] + 2a
-2 - a = 3
2a = k
a = -5
k = 2(-5) = -10

Is the relation in the table below a function?
Answer:
No
Step-by-step explanation:
A relation is a function if every x-value has exactly one y-value.
Because the x-value 1 has two y-values (-3 and 3), the relation is not a function.
Plotting (1, -3) and (1, 3) will produce a vertical line that intersects the function at two points.
Therefore, the relation is not a function.
Hope that helps.

The scale of a map is 1:4 000 000. Hint: 1:4 000 000 means that 1cm on the map = 4 000 000 on the ground. The distance between Leeds and London on this map is 8.125cm. Calculate the actual distance between Leeds and London. Give your answer in kilometres.
Answer:
325 km
Step-by-step explanation:
Given the scale :
1 : 4 ,000, 000
1cm measure in map = 4000000 on the ground
From the map :
Distance between Leeds and London = 8.125 cm
The actual distance on ground can be calculated thus :
1cm = 4,000,000
8.125cm = x
Cross multiply
x = 32500000 cm
Converting to kilometers :
1 km = 100,000 cm
x = 32500000
Cross multiply
100,000x = 32500000
x = 32500000 / 100000
x = 325
Hence, actual distance between Leeds and London is 325 km

t/1075 = 3/645
t = 1075(3/645) = 5
It will take 5 hours to travel 1075 miles at that rate.
Function c is defined by the equation c(n) = 50 + 4n. It gives the monthly cost, in
dollars, of visiting a gym as a function of the number of visits, n. Find the value of
c(7).
Answer:
The value of function at n = 7 is 78.
Step-by-step explanation:
Given function is:
c(n) = 50 + 4n
Here,
c represents the cost monthly cost of gym
n represents the number of visits to the gym
We have to find the value of c(7).
We will put n = 7 in the function.
Thus,
c(7) = 50 + 4(7)
c(7) = 50 + 28
c(7) = 78
Hence,
The value of function at n = 7 is 78.
The value of c(7) in the function c(n) = 50 + 4n is = 78
The function is defined as follows:
c(n) = 50 + 4n
where
function c is defined by the equation above
n is the number of visit
The function gives the monthly cost in dollars.
Therefore,
The value of c(7) can be found as follows:
c(7) = 50 + 4n
c(7) = 50 + 4(7)
c(7) = 50 + 28
c(7) = 78
