Answer:
a= infinite
b= one sol
c= no solutions
d= infinite
Step-by-step explanation:
I how this helped. Basically solve for X and see if you can. If you can't it is zero solutions, if you can solve it one way then it is one solution, and if will will always solve then it is infinite solutions.
Answer:
16
Step-by-step explanation:
Since this is a right triangle, we can use trig identities
sin theta = opp / hyp
sin 30 = 8 / NO
Multiply each side by NO
NO sin 30 = 8
Divide each side by sin 30
NO = 8 /sin 30
NO = 8 / 1/2
NO = 16
A=andy's age
b=belinda's age
3a=11+2b
a+b=-2+2b
wowie
a+b=-2+2b
minus b from both sides
a=b-2
subsitute b-2 for a
3a=11+2b
3(b-2)=11+2b
3b-6=11+2b
minus 2b from both sides
b-6=11
add 6 to both sides
b=17
subsitute
a=b-2
a=17-2
a=15
andy is 15
belinda is 17
