Answer:

  5x -2y = 30

Step-by-step explanation:

The slope of the line ...

  Ax +By = C

is -A/B. This means we can use A=5 and B=-2 in the equation we're looking for. The value of C will be one that makes the equation true at the given point.

  5x -2y = 5(4) -2(-5)

  5x -2y = 30

Step-by-step explanation:

10x - 10y = -20

-10y = -20 - 10x

y = -20/-10 - 10x/-10

y = 2 + x

-10x + 4y = -16

-10x + 4(2 + x) = -16

-10x + 8 + 4x = -16

-6x = -24

x = -24/-6

x = 4

y = 2 + x

y = 2 + 4

y = 6

Solution = (4,6)

Answer:

a. locate the rise over run between points

b. y2-y1/x2-x1

c. m=slope in y=mx+b

Step-by-step explanation:

a) Use rise over run,

() count how far apart up/down the y's are, and how far apart left/right the x's are

() down in the y's mean it is negative

b) change in y over change in x

() y2 - y1 / x2 - x1

c) find the "m" when it is in slope-intercept form

() y = mx + b

Using proportions, it is found that the hedgehog loses 3.45 ounces after 115 days of hibernation.

A proportional relationship is modeled by:

[tex]y = kx[/tex]

In which k is the constant of proportionality.

In this problem, the ratio between the weighs loss after x days in hibernation is given by:

[tex]k = \frac{0.24}{8} = \frac{0.84}{28} = \frac{2.25}{75} = \frac{2.79}{93} = 0.03[/tex]

Since this ratio is constant, the relationship is proportional, modeled by:

[tex]y = 0.03x[/tex]

The weight lost after 115 days of hibernation is y(115), hence:

[tex]y = 0.03(115) = 3.45[/tex]

The hedgehog loses 3.45 ounces after 115 days of hibernation.

Answer:

x=-5

Step-by-step explanation:

Group all constants on the right side of the equation

Subtract 3 from both sides:

x/5+3-3=2-3

Simplify the arithmetic:

x/5=2-3

Simplify the arithmetic:

x/5=-1

Isolate the x

Multiply to both sides by 5:

x/5 ·5= -1 · 5

Group like terms:

1/5 · 5x = -1 · 5

Simplify the fraction:

x = -1 · 5

Simplify the arithmetic:

x = -5

Step-by-step explanation:

The minimum point of a parabola is its vertex.

The equation of the parabola is [tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex]

The minimum point of the parabola is given as:

[tex]\mathbf{Minimum = (1.5,-1.5)}[/tex]

This represents the vertex (h,k).

So, we have:

[tex]\mathbf{(h,k) = (1.5,-1.5)}[/tex]

A parabola is represented with the following equation

[tex]\mathbf{y =a(x -h)^2 + k}[/tex]

Substitute values for h and k

[tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex]

Hence, the equation of the parabola is [tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex], where a does not equal to 0

The equation that is not equal to 54x-12 is (12x-3)4

(12x-3)4 equals 48x-12 while the other ones equal 54x-12

Answer: (12x-3)4

54x-12 is not equal to (12x-3)4

Answer:

Assuming the equation is: _x+5=4(–x–5) and not -x+5=4(–x–5),

Step-by-step explanation:

_x+5=4(–x–5)

_x+5=–4x–20

_x =–4x–25

_x +4x=–25

(4+_x) = -25

There is nothing left to do without more information.

Otherwise:

-x+5=4(-x-5)

The solution to the expression 12 ÷ (2+2/3)² is 1 11/16

Here, we have,

given that,

In this question, we have been given an expression.

12÷(2+23)2

The correct expression is: 12÷(2+2/3)²

We need to evaluate given expression.

Consider given expression,

12 ÷ (2+2/3)²

= 12 ÷ (8/3)²

= 12 ÷ 64/9

= 12/(64/9)

= 12 * (9/64)

= 3 * 9/16

= 27/16

We write above fraction as improper fraction.

= 1 11/16

Therefore, the solution to the expression 12 ÷ (2+2/3)² is 1 11/16

Step-by-step explanation: since the problem says that ”Quadrilateral JKLM is reflected in the X-axis the opposite of x is y, so when reflected off of the X-axis the y becomes the opposite sign.

Answer:  Forest B has 71 more trees than forest A after 100 years.

Step-by-step explanation:

I'm assuming that both functions should read as follows:  (the time, t, is shown as a power, instead as a multiplication).

A(t)=115(1.025)^t

B(t)=82(1.029)^t

Although A starts out with more trees (115), B is growing at 2.9% per year [1.029], versus 2.5% [1.025]for A.

A(100)=115(1.025)^(100)

A(100) = 1359

B(100) = 82(1.029)^(100)

B(100) = 1430

Forest B has 71 more trees than forest A after 100 years.
