The rate of change is the slope.
f(x) is the same as y...
f(x) = 3x + 9.....y = 3x + 9....and in y = mx + b form, the rate of change(slope) can be found in the m position.
y = mx + b
y = 3x + 9....so the slope or rate of change is 3...not 9...so answer is false
Answer:
C 10 in
Step-by-step explanation:
side of P is 
= 6
side of Q is 
= 8
for missing side use Pythagorean theorem
= 
r^{2} = 36 + 64
r^{2} = 100
r = 10 in
Answer:
Step-by-step explanation:
salut :
en utilisant le theorem de Pythagore on obtient :
AC²= AB² + BC²
(a+5)² = 7²+a²
a²+10a+25 = 49+a²
10a+25 =49
10a =24
donc : a = 24/10 = 12/5 = 2.4 unit
Answer: C
Step-by-step explanation:
Rejecting the null hypothesis means we've found a significant difference in the means. That means the probability that we'd see means so far apart by chance is less than our threshold of significance.
