Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3.

Y - 2 = -3(x + 7)
Y + 7 = -3 (x - 2)
Y + 2 = -3 (x - 7)
Y - 7 = -3 (x + 2)

Answer:

52 degrees

Step-by-step explanation:

A triangle's angles all add up to 180 degrees so we can create this equation:

x + 20 + 3x + 32 = 180

Combine like terms.

x + 3x + 20 + 32 = 180

4x + 52 = 180

Subtract 52 from both sides.

4x = 128

Divide.

128 / 4 = 32

x = 32

Plug in the value of x.

x + 20

32 + 20

52

Angle D is equal to 52 degrees.

Step-by-step explanation:

Answer: It will take 1.875 hours

Step-by-step explanation:

Given that time t required to do a job varies inversely as the number of people working.

we have it expressed as

t∝1/N

where t is time  required to do a job

N is the number of people working.

Introducing our constant of proportionality, we have tht

t=k1/N

t=k/N

Now since it takes 5 hr for 3 cooks to prepare the food , K becomes

t=k/N

5=K/3

K=5X3=15

Given that there are 8 cooks, time required to prepare dinner will be

t=k/N

t=15/8

t=1.875 hours

Answer:

m=-4/3

Step-by-step explanation:

The equation for slope is y2-y1/x2-x1

m=(y2-y1)/(x2-x1)

m=(12--4)/(1-13)

m=16/-12

m=-4/3

Answer:

260 months.

Step-by-step explanation:

Since there are 12 months in per year,

12 ⋅ 21 = 252.

There are 252 months in 21 years.

Then add the months left over.

252 + 8 = 260.

There are 260 months in 21 years, 8 months.

Step-by-step explanation:

Line is passing through the points (-4, 0) & (0, - 5)

Slope of the line

Answer:

x = 5

Step-by-step explanation:

Since both triangles are similar hence;

m<CAB = m<CDE

Given theta

m<CAB = 50degrees

m<CDE = 10x

Substitute the given angles

50 = 10x

Swap

10x = 50

Divide both sides by 10

10x/10 = 50/10

x = 5

Hence the value of x is 5

Its Intersecting The X- axis At X= -2 and x=6

Answer:

The factors of 18 are: 1, 2, 3, 6, 9, 18

The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

Then the greatest common factor is 2.

The greatest common factor of 18 , 24 and 40 is HCF = 2

The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF

Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers

Product of HCF x LCM = product of two numbers

Given data ,

Let the HCF be represented as H

Let the first number be represented as p

Now , the value of p = 18

Let the second number be represented as q

Now , the value of q = 24

Let the third number be represented as r

Now , the value of r = 40

And , the factors of 18 = 1, 2, 3, 6, 9 and 18

The factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24

The factors of 40 = 1, 2, 4, 5, 8, 10, 20 and 40

So , the HCF of 18 , 24 and 40 is the number 2

Hence , the HCF is 2

Welcome to the concept of the maths.

Here, we can see, that Linear equation always have highest power or degree of its variable as '1' ,

thus here, y = 3/x has degree as -1 and y = x^2 +5 has degree 2 ,

hence,

The equations that are NOT linear are

2.) y = 3/x and 5.) y = x^2 + 5
