Step-by-step explanation:

[tex]cos (90-A).sinA + sin(90 - A).cosA = 1 \\ \\ LHS = cos (90-A).sinA + sin(90 - A).cosA \\ \\ = sinA.sinA + cosA.cosA\\ \\ = sin ^{2} A + cos^{2} A \\ \\ = 1 \\ \\=RHS\\\\ reason \\ cos (90- \theta) = sin \theta \\ sin (90- \theta) = cos \theta \\ sin ^{2} \theta + cos^{2} \theta = 1 \\ \\ thus \: proved \\ [/tex]

Answer:

Option C

Step-by-step explanation:

Given inequality is,

-3(2x - 4) ≤ 7(3 - x)

Solve the given inequality further,

-6x + 12 ≤ 21 - 7x

(-6x + 12) + 7x ≤ (21 - 7x) + 7x

x + 12 ≤ 21

(x + 12) - 12 ≤ 21 - 12

x ≤ 9 Or {x real | x ≤ 9}

Therefore, Option C will be the correct option.

Answer:

0

-20

-7

Step-by-step explanation:

0 x any number = 0

4(-5) = -20

126/(-18) = -7

Answer:

1. 0

2. -20

3. -7

Step-by-step explanation:

1. 0 times anything is equal to nothing times something.

So, the first one is 0.

2. For 4 x -5, you can just do 4 x 5 x -1, which equals 20 x -1, whixh equals -20.

3. Remember, a negative times a negative = a positive. So, the number must be negative. Just do 126 / 18 x -1, which equals -7.

Answer:

2 2/3

Step-by-step explanation:

The quotient of two fractions is [tex]2\frac{2}{3}[/tex].

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given that, 2/3 divided by 1/4

To divide fractions, keep first fraction as it is change division sign to multiplication and inverse the second fraction.

Here, 2/3 ÷1/4

= 2/3 ×4/1

= 8/3

= [tex]2\frac{2}{3}[/tex]

Therefore, the quotient of two fractions is [tex]2\frac{2}{3}[/tex].

Answer:

The slope is : -2/2

Step-by-step explanation:

To find the slope, start on the y-axis. -2 passes through the line on the y-axis so start there. Go up 2 unites, which will bring you to the origin. Now you need to reach -2 on the x-axis. Go left two units, which gives you 2/2. It's rise over run. It's -2 because you went left two units not right. When you go left, or down it'll be negative.

2 = rise

/

-2 = run

(x₁,y₁) = (-2,0)

(x₂,y₂) = (0,-2)

m = (y₂ - y₁)/(x₂ - x₁)

m = (-2 - 0)/(0 - (-2))

m = -2/2

m = -1

Answer:-3<y<2

The answer should be D

Step-by-step explanation:

y = 2x

y = x + 1

y-1 = x

y = 2x

y = 2 (y - 1)

y = 2y - 1

y = -1

Answer:

$0.60

Step-by-step explanation:

Given that:

The ratio of number of cookies to the cost of cookies as:

Number of cookies : Cost of cookies = 15 : 9

It means, we get 15[tex]x[/tex] number of cookies when we pay $9[tex]x[/tex].

To find:

An equivalent ratio to represent the cost of 1 cookie.

Solution:

Here, we have to find nothing but the unit price or the price of 1 cookie.

This can simply be done by dividing the total cost of cookies with the total number of cookies.

Total cost of 15[tex]x[/tex] cookies is given as $9[tex]x[/tex]

Using unitary method:

Let us divide both the sides with 15[tex]x[/tex], we get:

Total cost of [tex]\frac{15x}{15x}[/tex] cookies is given as [tex]\frac{\$9x}{15x}[/tex]

Total cost of 1 cookie is given as $0.60

Answer:

x = 2.5

Step-by-step explanation:

12x - 13 = 17

12x = 17 + 13

12x = 30 (divide both sides by 12 to get x)

12x/12 = 30/12

x = 2.5

Answer:

where a is in the equation put 6.05 and where b is put 3.611

Step-by-step explanation:

-6.05 + (-3.611)

-6.05 - 3.611

-9.661

Answer:

-9.661

Step-by-step explanation:

First of you want to plug in a and b making the equation

-6.05 + (-3.611)  

or

-6.05 - 3.611

*I hope your teacher will allow you to use a calculator because of the decimals

Then you will add -6.05 + (-3.611) together

to get a negative answer of...

-9.661

Answer:

36

Step-by-step explanation:

x² + 12x - 40 = 0

x² + 12x    = 40

Now, 12/2 = 6. So add 6² = 36 to each side

x² + 12x + 36 = 40 +36
