Y=mx+b where m=slope which is change in y divided by change in x m=(-8-7)/(4-9)=-15/-5=3 so we have y=3x+b now we can use either point, I'll use (9,7), to solve for b or the y-intercept... 7=3(9)+b 7=27+b b=-20so our line is: y=3x-20
Answer:
x=8.5
Step-by-step explanation:
3 angles of a triangle = 180 degrees
c=45 a=50
180=45+50+b
130=45+b
85=b
b=d
d=85
10x=85
x=8.5
Answer:
17
Step-by-step explanation:
To obtain the tenth term, substitute n = 10 into the n th term formula, that is
n + 7 = 10 + 7 = 17 ← tenth term
