Answer:
y - (-9) = -10(x - 1)
Step-by-step explanation:
(1, -9) and (-10, 101)
Slope:
m=(y2-y1)/(x2-x1)
m=(101+9)/(-10-1)
m=110/(-11)
m = -10
Point-slope:
y - y1 = m(x - x1)
y - (-9) = -10(x - 1)
Answer:4y
I got the same answer as the other person but here’s a explanation
Explanation: when subtracting something that’s already a negative it just adds instead, I’ve learned to think of it as looking like a giant plus mark “-(-“ so basically y+3y= 4y
That's what I did and since the zeros would be -5 and 3 the answer would be 3 since it can't be a negative
The interest is $175
The formula we'll use for this is the simple interest formula, or: I=P*R*t
Where:
<span><span>P is the principal amount, $5000.00.
</span><span>r is the interest rate, 7% per year, or in decimal form, 7/100=0.07.
</span><span>t is the time involved, 6....month(s) time periods.
</span><span>Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into"year" as well.
Do this by dividing your time, 6- month(s), by 12, since there's 12 months in 1 year. </span><span>So, t is 0.5....year time periods.
</span></span>
To find the simple interest, we multiply 5000 × 0.07 × 0.5 to get that: $175
