What is the equation for the line with slope m=−4 and y-intercept b=3
andreev551 [17]

Answer:

ok so i am going to give you a litle saying to help you remember the way it goes ok. this problem is in slope-intercept form

"y=mx+b,,b is my y-intercept you'll see,m is my slope which is rise over run"

so if -4 is your slope it will go where the m is in the formula y=mx+b so it would now be y=-4x+b and then the b is your y-intercept so 3 would go where the b is in the formula now now since we plugged in all the parts.

<u>the answer is y=-4x+3 </u>

Step-by-step explanation:

Jerry climbed 210 feet in elevation. he want down 300 feet. what integer represents his toal changes in elevation.
babymother [125]

For every action you want to record the "Distance", you do not want to find the displacement. 210 feet + 300 feet = 510 feet. His total distance traveled is 510 feet

Displacement however would be -90 = 210 - 300 because he is now -90 feet from where he begun. The reason the 90 is negative is because he is lower now than he was before because the downward movement was greater than the upward movement.

11. Kamala borrowed 26400 from a bank to buy a scooter at a rate of 15% per annum compounded yearly. What amount will she pay at
oee [108]
<h2>Answer </h2>

Amount (A) = P[1 + (r/100)]n

Principal (P) = ₹ 26400

Time period (n) = 2 years 4 months

Rate % (R) = 15% compounded annually

<h3>Steps </h3>

First, we will calculate Compound Interest (C.I) for the period of 2 years

A = P[1 + (r/100)]n

= 26400[1 + (15/100)]²

= 26400[(100/100) + (15/100)]²

= 26400 × 115/100 × 115/100

= 26400 × 23/20 × 23/20

= 26400 × 1.3225

= 34914

C.I. = A - P

= 34914 - 26400

= 8514

Now, we will find Simple Interest (S.I) for the period of 4 months

Principal for 4 months after C.I. for 2 years = ₹ 34,914

<h3>We know that ,</h3>

S.I = PRT/100

Here T = 4 months = 4/12 years = 1/3 years

S.I. for 4 months = (1/3) × 34914 × (15/100)

= (1/3) × 34914 × (3/20)

= 34914/20

= 1745.70

Total interest for 2 years 4 months = 8514 + 1745.70

= 10259.70

Total amount for 2 years 4 months = 26400 + 10259.70

= ₹ 36659.70

<h3>So , the correct answer is ₹ 36659.70 . </h3>
