<span>(8,9) m = 0.5
point slope form
y - y1 = m (x - x1)
so
equation
y - 9 = 0.5(x - 8)
answer
</span>
y - 9 = 0.5(x - 8)
I was again led to this question, Brainly seems to enjoy doing this, and i might as well say something. Glad you figured it out and i hope you get it right.
Answer:
a. 8 years
b. $49.20
Step-by-step explanation:
The computation is shown below:
a. The mark age is
Given that
232 is 8 times of the sum of mark and his sister ages
And, his sister is 21
So,
Let us assume the mark age be x
now
8(x + 21) = 232
x + 21 = 29
x = 29 -21
x = 8
b. The original price of the socks is
As each pair get $3 off
And she bought 6 pairs for $31.20
= $31.20 + 6 × $3
= $31.20 + 18
= $49.20
3:1
