SOMEONE DO NUMBER 2 FOR ME WHERE IT SAYS "What percent is shaded" IM GIVING BRAINLIEST

Answer:

The answer is (7,3)

Step-by-step explanation:

the answer is the point where the two lines intersect.

Answer: The answer is the second option

Step-by-step explanation:

Divide each term by 4 and simplify x>8

Answer:

The answer to the first one is y=3/2x-27/2

The answer to the second one is y=-3/5x+6/5

Step-by-step explanation:

1. 2y-3x=-27

first, you want to add '3x' to both sides.

2y=3x-27

then you want to divide '2' from both sides. you do not want to use the 'y' because you want to keep the 'y' on its own side.

y=3/2x-27/2

2. 5y+3x=6

First, you want to subtract '3x' from both sides.

5y=-3x+6

Now, you want to divide '5' from both sides.

y=-3/5x+6/5

Answer:

y= -1/3x+2

Step-by-step explanation:

A slope intercept equation follows the format of y=mx+b. The m means slope and the b means y-intercept.

To find slope use the two points given(0,2) and (3,1). Start at the point highest on the line(0,2), and subtract the y values, for this graph 2-1. Then do the same with the x values, for this graph 3-0. Now you have your y and x values. Slope = y/x, so substitute the variables and you get 1/3. From left to right, the line is slanting downward, so it's a negative slope, which makes your slope -1/3.

To find the y-intercept, find where the line crosses the y axis and use the y value from that point. The line on this graph crosses at the point (0,2), so 2 is the y-intercept.

Lastly, put your new values into the slope intercept equation. Substitute m for your new slope and b for the y-intercept. That gives you your answer y=-1/3x+2.

Answer:

w = 13

Step-by-step explanation:

Right angle: 90°

Write an equation:

(4w + 5)° + 33° = 90°

Solve for w.

(4w + 5)° = 90° - 33°

(4w + 5)° = 57°

You can take away the brackets.

4w + 5 = 57

Isolate w.

4w = 57 - 5

4w = 52

w = 52 ÷ 4

w = 13

Step-by-step explanation:

7x + 10 = 4x + 16

3x + 10 = 16 (subtract 4x on both sides)

3x = 6 (subtract 10 on both sides)

x = 2 (divide 3 on both sides)

Answer:

Step-by-step explanation:

Step-by-step explanation:

Case 1 :

[tex]3x + 2y = 6 \\ 4x + y = 2 \\ 3x = 6 - 2y \\ x = \frac{6 - 2y}{3} = \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) + y = 2 \\ 8 - \frac{8y}{3} + y = 2 \\ - 1.67y = - 6 \\ [/tex]

[tex]y = 3.59 \\ x = 2 - \frac{2y}{3} \\x = 2 - \frac{2 \times 3.59}{3} \\ \\ x = - 0.39[/tex]

Case 2 :

[tex]3x + 2y = 6 \\ 4x - y = 2 \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) - y = 2 \\ 8 - \frac{8y}{3} - y = 2 \\ - 3.67y= - 6 \\ y = 1.63[/tex]

[tex]x = 2 - \frac{2y}{3} \\ x = 2 - \frac{2 \times 1.63}{3} \\ x = 2 - 1.087 \\ x = 0.913[/tex]

Answer:

1

Step-by-step explanation:

74/2 = 37/x so u have to cross multipy these two so 74*x = 2*37

then 74x =74 so x=74/74 which is 1 :)

Answer:

40 people

Step-by-step explanation:

Step one:

given data

let the total number of persons be x

There are 28 women

The number of men = 30% of x

Step two:

So the total person is given as

30/100*x+28= x

solve for x

0.3x+28= x

collect like terms

x-0.3x= 28

0.7x= 28

divide both sides by 0.7

x= 28/0.7

x= 40 people

Answer:

x = 4

y = 10

Step-by-step explanation:

7x - 3 = 25

7x = 28

x = 4

12y + 35 = 155

12y = 120

y = 10

Hey there!

There are actually a few possible equations, but I will choose these:

FOR X:

7x - 3 = 25

7x = 28

x = 4

FOR Y:

12y + 35 = 155

12y = 120

y = 10

Hope it helps and have a great day!!

Answer:

Step-by-step explanation:

Trigonometric identities are used to show the equality of expressions involving trigonometric functions. These trigonometric functions are the sine, the cosine, and the tangent as well as their respective reciprocals which are cosecant, the secant, and the cotangent,

Some trigonometric identities are:

tanθ = sinθ / cosθ; secθ = 1 / cosθ; cosecθ = 1 / sinθ; cotθ = 1 / tanθ = cosθ / sinθ

The angle addition formula for cos is given as:

cos(α + β) = cosαcosβ - sinαsinβ

Therefore:

cos(a + b) = cosacosb - sinasinb
