The formula to convert, temperature measured in degrees Celsius, C, to temperature measured in degrees Fahrenheit, F, is below. F = 9/5 (C) + 32
Mariah records the outside temperature to be 15° Celsius. What is the
temperature, in terms of degrees Fahrenheit?

A. 35
B. 59
C. 47
D. 40

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun
