Answer:
y = -6x +9
y = 9·(1/3)^x
Step-by-step explanation:
In each case, the y-intercept is 9.
Linear
The slope is rise/run = (3-9)/(1-0) = -6, so the equation is ...
y = mx + b . . . . . . . slope m, intercept b
y = -6x +9
Exponential
The ratio of value at x=1 to that at x=0 is 3/9 = 1/3. That is the "growth factor," so the equation is ...
y = 9·(1/3)^x
Answer:
No
Step-by-step explanation:
For a right triangle, according to the Pythagorean Theorem, the 2 sides squared must equal the hypotenuse squared. ()
The hypotenuse is the longest side so
36 + 49 does not equal 169
