c.8,1
d.19.8
2 answers:
Answer:
B: 7.5
Step-by-step explanation:
Use the formula a²+b²=c² to calculate. a=x b=13 c=15. Simply plug in the numbers to the coresponding letters
a²+13²=15²
a²+169 = 225
-169 -169
__________
a²= -56
a = 7.5
Answer:
b
Step-by-step explanation:
so we now a and b are the legs let's say a=13 and b=x/? we also have c=15 which is the hypotenuse. let's get started.
a²+b²=c²
13²+x²=15²
169+x²=225
225-169=56
x²=56
so we square root both of them.
x=7.5 rounded

Answer:
y = 1/6x + 7/3
Step-by-step explanation:
(-2 ,2) and (-8, 1)
Slope=(1-2)/(-8- - 2) = (-1/-6) = 1/6
b = 2 - (1/6)(-2) = 2 - 2/6 = 2 - 1/3 = 7/3
