What is the slope of a line perpendicular to the line whose equation is x +y = 3.
Fully reduce your answer.

Answers

Answer:

slope = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + y = 3 ( subtract x from both sides )

y = - x + 3 ← in slope- intercept form

with slope m = - 1

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-1}[/tex] = 1

Ms. Dorothy deposited ₱40,000 in a bank new plan paying 7.2% simple interest per annum if withdrawn after 5 years, otherwise the plan will not apply. How much interest will she gain after maturity of the plan

Answers

Answer:

14,400.00

You're going to take 40,000 multiplied by 7.2 which gives you the interest for one year. Multiply that by 5 to get through interest for 5 years.

The amount of interest that she gained after the maturity of the plan will be ₱14,400.

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

I = (PRT)/100

Where I is the interest, P is the principal, R is the rate of interest, and T is the time.

Ms. Dorothy deposited ₱40,000 in a bank new plan paying 7.2% simple interest per annum if withdrawn after 5 years, otherwise, the plan will not apply.

Then the amount of interest that she gained after the maturity of the plan will be

I = (40,000 x 7.2 x 5) / 100

I = 400 x 7.2 x 5

I = ₱14,400

The amount of interest that she gained after the maturity of the plan will be ₱14,400.

If a lost male child is found who is 145 cm tall, determine an interval of likely ages for the child. Give whole numbers.

≤ age ≤

Answers

We can deduce here that for a height of 145 cm, a likely interval of ages could be: 12 ≤ age ≤ 15

What is inequality?

In mathematics, an inequality is a mathematical statement that expresses a relationship between two quantities, indicating that one quantity is greater than or less than another. It represents a comparison or a difference in values.

For a height of 145 cm, a likely interval of ages could be:

12 ≤ age ≤ 15

This range assumes that the child's height falls within the average height range for boys aged 12 to 15 years. However, it's important to consider that individual variations and growth patterns can influence a child's height, so this interval should be interpreted with caution.

Mr. Kimball sells computer software. He earns a base salary of $41,250 and 8% commission on his sales. Write an equation to represent Mr. Kimball’s total pay p after selling d dollars of software.

Answers

Answer:

P=0.08d+41,250

Step-by-step explanation:

The total amount earned, p which is the sum of the base salary and the commision on sale can be expressed as ;

p = 41250 + 0.08d

Given the Parameters :

Base salary = 41250Commission percentage = 8% = 0.08Amount of sales made = d

The total pay after selling software worth $d can be expressed thus :

Base salary + (commission percentage × amount of sales)

Total pay = 41250 + (0.08 × d)

p = 41250 + 0.08d

Therefore, the total pay, p is expressed as 41250 + 0.08d

The slope of the given line is 4.

What is slope?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Given that, a line passing through points (3, 9) and (1, 1) we need to find the slope of the line,

Slope = y₂ - y₁ / x₂ - x₁

So,

Slope = 9-1 / 3-1 = 8/2 = 4

Hence, the slope of the given line is 4.

Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions. PLS HELP ILL GIVE BRAINLIEST

Answers

Answer:

x is eighteen

y is fifty four

Answer:

x= 18 degrees and y=54 degrees

Step-by-step explanation:

Look at the top of the line AB. You can see that

3x+y+72=180

Now, look at the left side of the line CD. You can see that

y+90+2x=180

Hence, you have 2 equations in 2 unknows, which are possible to solve.

In resume, the 2 equations are:

3x+y+72=180

2x+y+90=180

By substracting the second equation to the first one, it yields

x-18=0

which implies x=18.

Now, we can susbstitute this value on the fist equation:

3(18)+y+72=180

54+y+72=180

y+126=180

y=180-126

y=54

We can corroborate these result in the second equation:

2(18)+54+90=

36+54+90=

90+90=

180.

P = 25m - 15

Step-by-step explanation:

Kindly find attached the table of values for your reference.

Step one:

let us set up the coordinate using the value of p and m

p=35

p1=10

m=2

m1=1Tthe cordinate is (p1,p),(m1,m)= (y1,y),(x1,x)

(1,10), (2, 35)

the slop is given as, slope m = (p- p1)/(m - m1)

m=(35-10)/(2-1)

m = 25

from the equation of line y=mx+c

y = 25x + c

10 = 25(1) + bc

c= -15

y = 25x - 15

in term of m and p we have  P = 25m - 15
