Answer:
B
Step-by-step explanation:
First create the equation that has slope of -1 in the form of y=mx+b. Because the slope is -1, m=-1, so the equation is y=-x+b. Now we see that we are given the point (-3, 8) as an intersection point. Substitute x and y for -3 and 8 in our equation. With this information, our equation becomes 8=3+b. Solving, b=5. Our equation is now y=-x+5.
Simplifying all of the answer choices, we have
A. y=-x-5
B. y=-x+5
C. y=-x-5
D. and E. as what they already show
The only answer that matches is B.
Okay, move the decimal behind the 8. There are 4 places before the decimal so it is nagitive. If there are places Infront of the decimal is nagitive. So the answer is 8.235×10-4
Hi ty for the points, answer is the light blue one
Answer:
90
Step-by-step explanation:
I believe it is 90 because when you take 30 minutes plus 30 minutes that makes 1 hour, and when you take 5 plus 5 equals 10. So, that means 10 every hour. So 10 times 9 is 90. Which gives you the answer of 90 mirror frames.
Complete question is;
If Pablo invests $4200 for 3 years and earns $630
A) what is the simple interest rate?
B) Pablo’s goal is to have $5000 after 4 years. Is it possible with a rate of 6%? Explain.
Answer:
A) Rate = 5%
B) Yes, it is possible for him to earn $5000 after 4 years with an interest rate of 6%
Step-by-step explanation:
A) Formula for interest is;
i = PRT
We are given;
i = 630
P = 4200
T = 3
Making R the subject;
R = i/PT
R = 630/(4200 × 3)
R = 0.05
This is 5%
B) Formula for value of principal after interest period is;
A = P(1 + RT)
P = 4200
R = 6% = 0.06
T = 4 years
Thus;
A = 4200(1 + (0.06 × 4))
A = $5208
Thus, it is possible for him to earn $5000 after 4 years with an interest rate of 6%
