A. one solution
B 4(2x-5) = 4
2x-5 = 1
2x = 6
x=3
Answer:
y = 6x - 4
Step-by-step explanation:
slope (m) is 6
y intercept (b) is -4
plug values into y = mx + b:
y = 6x - 4
Given:
Time spend on every 2 questions = 5 minutes.
To find:
The missing values for the given table.
Solution:
Let x be the number of questions and y be the number of minutes.
We have,
Time spend on every 2 questions = 5 minutes
Time spend on 1 question =
minutes
Time spend on x questions =
minutes
Now,

For x=0,

For x=1,

For x=2,

For x=3,

For x=4,

Therefore, the required table is
Questions : 0 1 2 3 4
Time (minutes) : 0 2.5 5 7.5 10
creo que quieres decir la suma
si es la suma eso da 2.8
Answer:

Explanation:
h

is defined for all Real values of
x
except those values for which
x

−
x

So if
