A) the image on the lower left is correct. Because the equation is set up as “F=“, F goes on the y-axis. The y-intercept is positive 32.

B) the slope is 9/5 because the equation is in the form of y=mc+b, where m is the slope. F increases 9/5 degrees for each increase of 1 C. The F-intercept is 32 and it represents the temperature 32 F corresponding to 0 C.

12. In PQR if mP is 14 less than five times x, mQ is five less than x, and mR is nine less

mash [69]

Answer:

Step-by-step explanation:

mP=5x-14

mQ=x-5

mR=2x-9

we know that all the angles in a triangle= 180

that means (5x-14)+(x-5)+(2x-9)=180

5x-14+x-5+2x-9=180 we add the variables and the numbers

8x=180+28

8x=108

x=26

mP=130-14=116

mQ=26-5=21

mR=43
