An easy way to find it (aka the avarage) is to add the two numbers together and divide the result by 2 so
15+37=52
52/2=26
another way is to subtract 15 from 37 and divide the result by 2, then you add this to the smaller number so
37-15=22
22/2=11
15+11=26
also
37-11=26
C. It’s graph must have a slope of 1
Answer:(d): y=ax+b (a≠0); (d1)y=-4x+13
because of (d)⊥(d1) --> a.(-4)=-1 --> a=
(d): y=+b. (d) pass through P(-1;-2) so we have
-2=(1/4).(-1)+b ---> b=
(d) y=
Answer:
b=18
Step-by-step explanation:
1) Add 2/9b to both sides:
3=5/9b-7
2) Add 7 to both sides:
5/9b=10
3) Multiply both sides by the reciprocal of 5/9: (9/5)
b=90/5
4) Simplify:
b=18
