Answer:
see attached image
Step-by-step explanation:
F(x) = 2x + 5 is a linear graph because the exponent on x is 1. I tell my students that think of graphs having one less turn/corner that the value of the highest exponent. so since 2x has a exponent of 1, 1-1 =0 so it has no turns or its a straight line.
this has a slope of 2 or 2/1 or up 2 and right 1 from the y intercept which is 5
so mark 5 on the y axis and a from there go up 2 and right 1 and make another point. Join these points and you have your graph
and
g(x) = (x-5)/2 is its inverse and is found:
F(x) = 2x + 5 write it this way y = 2x + 5
now swap the x and y x = 2y - 5
solve for y
x = 2y + 5
- 5 -5
x - 5 = 2y
/2 /2
(x-5)/2 = y
it can be written as y = x/2 - 5/2
and graphed the same way as above with a 1/2 slope and -5/2 y intercept
This should be the correct answer.
Answer:
cups of flour.
Step-by-step explanation:
Given that:
is the number of cups of water to be mixed with flour for making tortillas.
is the number of cups of flour to be mixed with water for making tortillas.
Relation between and
is given by the equation:
To find:
Number of cups of flour to be added if number of cups of water to be used is 1.
Solution:
We are given an equation with two variables.
Value of one variable is given and we have to find the value of other variable.
Number of cups of flour to be added =
