Step-by-step explanation:

Hey there!!

Just simply work with it.

We know that we have to use one point formula to find the equation of a st.line passing through point and slope is given.

So, just do accordingly.

The point is (2,-6) and slope is -1.

[tex](y - y1) = m(x - x1)[/tex]

Where, "m" is a slope.

Put all values.

[tex](y + 6) = - 1(x - 2)[/tex]

Simplify them to get answer.

[tex](y + 6) = - x + 2[/tex]

[tex]y = - x - 4[/tex]

Therefore the equation is y= -x-4 OR can be written as x+y+4=0.

Hope it helps....

Answer:

x=-6

Step-by-step explanation:

7x-9x=6+6

-2x=12

x=-6

Answer:

x = -6

Step-by-step explanation:

Step 1: Write out equation

7x - 6 = 9x + 6

Step 2: Subtract 7x on both sides

-6 = 2x + 6

Step 3: Subtract 6 on both sides

-12 = 2x

Step 4: Divide both sides by 2

-6 = x

Step 5: Rewrite

x = -6

Answer:

see explanation

Step-by-step explanation:

Evaluate u for each value of n by substituting value of n into u, that is

n = - 1 → u = - 5(- 1)² + 4(- 1) = - 5(1) - 4 = - 5 - 4 = - 9

n = 0 → u = - 5(0)² + 4(0) = 0 + 0 = 0

n = 1 → u = - 5(1)² + 4(1) = - 5 + 4 = - 1

n = 2 → u = - 5(2)² + 4(2) = - 5(4) + 8 = - 20 + 8 = - 12

Thus

   n          u

   - 1         - 9

     0          0

      1          - 1

      2          - 12

Answer:

Hi there!

Your answer is:

x= 1

Step-by-step explanation:

Goal- get all X's on one side, and all whole numbers on the other

2+3x -x = 4x

First, combine like terms on each side of the equal sign

2+ 2x = 4x

Next, think about the additive inverse property. What, added to 2x, equals 0? 2x + (-2x) =0! So, we subtract 2x from both sides!

2= 4x-2x

Simplify

2= 2x

Divide both sides by the coefficient of x (in this case, 2)

2/2 = x

2/2 is equal to 1

1= x

Hope this helps!

Answer:

x = 1

Step-by-step explanation:

Combining the x terms, we get  

2 + 2x = 4x, or 2 = 2x.

Then, after we divide both sides by 2 to isolate x, we get x = 1

Answer:

3 : 4

Step-by-step explanation:

Men = 40, Women = 30

Ratio of women to men

[tex] = \frac{30}{40} = \frac{3}{4} = 3 : 4 \\ [/tex]

The Ratio of the women to men is 3/4.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, In a small business, 40 of the employees are men and 30 of the employees are women.

Since There are 30 women on 40 men in the company

Thus, ratio of the women to men = 30/40

The ratio of the women to men = 3/4

Therefore, the ratio of women to men is 3/4 in the organization.

Answer:

The answer is B.

Step-by-step explanation:

You have to use area of trapezoid formula, A = 1/2×(a+b)×h where a, b are the side lengths and h is height :

[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]

[tex]let \: a = 6,b = 16,h = 5[/tex]

Answer:

Given MC = 4

AN = 14

To Find, the length of NB

Step-by-step explanation:

AB is a line which has midpoint “C”. Now the line is divided into two equal portion AC and CB.

The AC has midpoint “M” and MC is 4, so AM will also be 4.

N is the midpoint of CB. So, CB = CN + NB

Now we know AC = AM + MC = 4  + 4 =8

Given, AN = 14

AN = AC + CN

14 = 8 + CN

CN = 6

Since N is the midpoint of CB then, CN = NB

Therefore, the NB is 6

Answer:

NQ = 26 cm

Step-by-step explanation:

A line bisector divides a line into two equal segments.

Given that line l is the bisector of segment NQ, it then means it divides NQ into two equal segments, namely, segment NP and segment PQ.

Thus, NP = ½ of segment NQ

Therefore, if NP = 13 cm,

13 = ½*NQ

multiply both sides by 2

2*13 = NQ

26 = NQ

NQ = 26 cm

Answer:

f(- 2) = 21

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x)

f(- 2) = - 5(2(- 2) + 1) + 6 = - 5(- 4 + 1) + 6 = - 5(- 3) + 6 = 15 + 6 = 21

The equivalent expression of 3x + 4y = 15 is y = 15/4 - 3x/4 so option (A) will be correct.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

In another word, the equation must be constrained with some constraints.

Given the expression,

3x + 4y = 15

4y = 15 -3x

y = 15/4 - 3x/4

Hence "The equivalent expression of 3x + 4y = 15 is y = 15/4 - 3x/4".

CORRECT

Answer:

False

Step-by-step explanation: A rational number is any number can be expressed as a fraction. Whereas, a whole number is a positive number without a decimal or fractions. Every rational number is may or may not be a whole number.

The statement "Some rational numbers are whole numbers" is:

True

A rational number is any number that can be expressed as a fraction of two integers, where the denominator is not zero. A whole number is any integer that is not negative.

All whole numbers are rational numbers. This is because any whole number can be expressed as a fraction with a denominator of 1.

For example, the whole number 3 can be expressed as the rational number 3/1.

However, not all rational numbers are whole numbers. For example, the rational number 1/2 is not a whole number, because it cannot be expressed as a fraction with a denominator of 1.

Therefore, "Some rational numbers are whole numbers" is True.
