Will give brainliest! someone graph these, i can't graph them.

see attached imageStep-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 5so 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 graphand g(x) = (x-5)/2  is its inverse and is found:F(x) = 2x + 5 write it this way y = 2x + 5now swap the x and y    x = 2y - 5solve for yx = 2y + 5- 5       -5 x - 5 = 2y/2        /2 (x-5)/2 = yit can be written as y = x/2 - 5/2and graphed the same way as above with a  1/2 slope and -5/2 y intercept

vertical=18cm horizontal=18cm hypotenuse=25.5

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
