y= 3x+7
y = -2x-3
What would be the x and y for that solution

Answer:

Step-by-step explanation:

Strictly speaking, 15% isn't precisely the same as 0.15; 0.15 is the decimal fraction used to calculate 15% of some quantity.

15% of 52 is indeed 7.8.  $7.80 is the discount that is to be SUBTRACTED  from the regular price ($52).  Adding $7.80 to $52 is incorrect.  

Also, 52 + 7.8 - 59.8 is incorrect:  it's not an equation (but should be one), and we should be subtracting $7.80 from $52.

The area of the hexagon is the amount of space on it

The area of the hexagon is 374.112 square inches

The perimeter is given as:

P = 72 inches

The length of the hexagon is calculated using:

L = P/6

So, we have:

L =72/6 = 12

The area is then calculated as:

A = 1.5[tex]\sqrt 3[/tex] * L^2

This gives

A = 1.5[tex]\sqrt 3[/tex] * 12^2

Evaluate the product

A = 374.112

Hence, the area of the hexagon is 374.112 square inches

Answer:

a) (1 , 4)

b) (-1 , 0) and (3 , 0)

Step-by-step explanation:

The turning point also call the vertex of the function is shown by in this case the maximum which is at the point (1 , 4). The roots, also known as zeros, are the values at which the graph crosses the x-axis. In this case it is at points: (-1 , 0) and (3 , 0)

Answer:

point - slope form: y+1 =2(x+2)

slop - intercept form:  y =2x +3

standard form : 2x -y = -3 or -2x+y = 3

Step-by-step explanation:

find slope from given points using slope formula y₂ -y₁ / x₂ -x₁

slope m =5-(-1)/1-(-2) =6/3 =2

point - slope form is y - y₁ =m (x - x₁) where x₁ and y₁ are coordinates of one of the given points so

y - (-1) = 2(x -(-2))

y+1 =2(x+2)

slop - intercept form is y =mx +b where m is a slope and b is y intercept

now if you rearrange y+1 =2(x+2) as y =......

y+1 =2(x+2) → y+1=2x+4 → y = 2x+4-1 → y =2x +3

standard form is Ax +By = C where A,B,C are numbers; then by rearranging the equation again, it will be

2x -y = -3

graphing is done by using  slop - intercept form:  y =2x +3

Step-by-step explanation:

The formula to find a discriminant is b^2-4ac.

ax^2+bx+c is the quadratic equation. In your equation, -1 is a, -1 is b, and 5 is c. Now we can plug in the numbers into the discriminant formula b^2-4ac!

(-1)^2-4(-1)(5)=

Answer:

4/5

Step-by-step explanation:

4x-5y=0  

subtract 4x on both the sides  

4x-4x-5y = 0-4x  

-5y = -4x

divide by -5 on both the sides  

-5y/-5 = -4x/-5

y =( 4/5 )x

36 / pi = h

Using 3.14 for pi

h =11.46496815 inches

Using the pi button

h =11.45691559 inches

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the volume and the radius

576 = pi ( 4)^2 h

576 = pi 16 h

Divide each side by 16 pi

576/16 pi = pi 16 h/ 16 pi

36 / pi = h

Using 3.14 for pi

h =11.46496815 inches

Using the pi button

h =11.45691559 inches

Answer: (x,y)=(-2/3,15)

Negative 2 over three

Answer:

For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is not necessary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x - 1).

since the strongest correlation is either 1 or negative 1, and weakest is closer to 0,

now, lets order from weakest to strongest:

[tex]\sqrt{45^{2} + 45^{2}} = \sqrt{4050}[/tex]

Answer:

If x is greater than 0, then y is greater than x

For example:

x = 2 => y = 4(2) = 8, 8 > 2

x = 3 => y = 4(3) = 12, 12 > 3

If x is = 0, then y is equal to x, because x = 0 => y = 4x = 4(0) = 0 => x = y = 0

If x is less than 0, then y is smaller than x

For example:

x = -2 => y = 4(-2) = -8, -8 < -2

x = -3 => y = 4(-3) = -12, -12 < -3

Let's start by subtracting 3 from both sides

2x=x-7

Now, subtract x from both sides

x=-7

Let's plug it in to make sure!

2(-7) +3= (-7)-4
