If m/n =5, then m2−25n2 =

(1) m > 0

(2) 2m + n= 26

Step-by-step explanation:

No Edginuity answer :If the model is good, then both points will check in the equation. Substituting 8 for x and 5 for y in the equation results in 56 – 50 = 3, which is not true. Therefore, the model is not good. Using (–12, –9) as a check results in –84 + 90 = 3. The constant value in the equation should be 6, not 3. In slope-intercept form, the y-intercept should be –3/5.
