Answer:
d. y=5
Step-by-step explanation:
The equation of a line parallel to the x-axis will always be in the form y=b, where b is the y-intercept (where on the y-axis the line crosses). So, for y=5, the line crosses the y-axis when y is equal to 5.
The equation of a line parallel to the y-axis will always be in the form x=d, where d is the x-intercept (where on the x-axis the line crosses). So, for option a, x=5, it is a vertical line that crosses the x-axis when x is equal to 5. It is therefore not parallel to the x-axis.
Option b gives an equation that isn't for a linear relation entirely.
Linear equations are typically given in the form y=mx+b, where m is the slope of the line and b is, again, the y-intercept. Option c presents the equation of y=x, and this can be rewritten as y=1x+0. In other words, the slope of the line is 1 and it crosses the y axis when y is equal to 0. Lines that are parallel to the x-axis will always have a slope of 0, so therefore, this line is not parallel to the x-axis.

Answer:
The correct answer is 2 . (1 , 3)
Step-by-step explanation:
A function is used to denote a particular relationship between variables. They can even be visualized as an input-output machine.
Every function has a domain set and a co-domain set. A function maps elements from domain to the elements of co-domain.
Here the domain can be considered as { 0 , 2 , 5 , 7}.
Here the co- domain can be considered as { 1 , 3, 8 , 2}.
For a function to be a valid function, all elements from the domain should have an image in the co- domain and every element of domain should have exactly one image in the co-domain.
Here the options 1 , 3 and 4 violate the second necessary criteria for the function to be valid.
Hence (1 , 3) is the correct answer.

Answer:
13
Step-by-step explanation:
(3 times 2)+7=x
6+7=x
x=13
We have an equation: 56/? = 4/100
Cross multiply:
4*? = 56*100
⇒ ? = 56*100/4
⇒ ?= 1,400
4% of 1,400 days is 56 days~
