An equation is a collection of variables and constants. The value of x and y for the system of the equation as -2x - 4y = -18 and x = y will be x = 3 and y = 3.

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.

As per the given system of equations,

-2x - 4y = -18 and x = y

Substitute, x = y

-2(y) - 4y = -18

-6y = -18

y = 3 and x = 3

Hence "The value of x and y for the system of the equation as -2x - 4y = -18 and x = y will be x = 3 and y = 3".

Answer:

songs in the final CD 13

Step-by-step explanation:

the 100% = 16

-------------------

16/x=100/62.5

(16/x)*x=(100/62.5)*x

16=1.6*x

16/1.6=x

10=x

x=10

This is the 62.5% of 16

---------------------

now the new 100% is 10 + 16 = 26

but during the editing process 50% are removed

and the 50% of 26 (half of it) is = 13

Every day mass of sunfish is multiplied by factor of (ln(67/50)/6).

In the given question we have a relation between mass of sunfish and time elapsed t. Relation is

M(t) = (67/50) ^(t/6+4) -----(1)

To find out the factor which multiple by mass of sunfish each day, we can take derivative of M(t) function.

Derivative of a function measures the change in fucyion value with respect to change in its argument. It gives rate of change of function with respect to change in given variable value. So, in this problem derivative of mass function M(t) gives the rate of change of M(t) with respect to time , t .. It is represented by dM(t)/ dt.

dM(t)/ dt =( 67/50)^(t/6+4) (1/6)ln(67/50)

We have the used derivative formula d(a^t)/dt = a^t (1) lna

dM(t)/dt = ln(67/50)/6 (67/50)^(t/6+4)

dM(t)/dt = (ln(67/50))/6 M(t)

We can see here that mass funtion is increased by factor ln(67/50)/6 each day.

The required value of RT is 10 units when RS = 7, ST = 3x, and RT = x + 9.

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment RT, where the length of line segment RT refers to the distance between its endpoints, R and T.

RS = 7, ST = 3x, and RT = x + 9

R______________S______________T

⇒ RT = RS + ST ....(i)

Substitute the values of RS = 7, ST = 3x, and RT = x + 9,

⇒ x + 9 = 7 + 3x

⇒ 3x - x = 9 - 7

⇒ 2x = 2

⇒ x = 1

Substitute the values of x = 1 in RT = x + 9

So RT = 1 + 9 = 10

Hence, the value of RT is 10 units.

W=5+v/v-3

then this can be expressed as:

W(v-3) = 5+v

Wv - 3W = 5+v

then we can rearrange the expression as:

Wv - v = 5 + 3W

[tex]x=-9, \quad x=\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=(4x-1)(x+9)[/tex]

The roots of a function are the x-values for which the function equals zero.  Therefore, to find the roots, set the function to zero and solve for x.

Set the function to zero:

[tex]\implies f(x)=0[/tex]

[tex]\implies (4x-1)(x+9)=0[/tex]

Zero Product Property

If a ⋅ b = 0 then either a = 0 or b = 0 (or both).

Apply the zero product property:

[tex](4x-1)=0 \implies x=\dfrac{1}{4}[/tex]

[tex](x+9)=0 \implies x=-9[/tex]

From the information, the laptop he wants is in stores for $749.99 but is on sale for 25% off and after the discount is removed, a tax rate of 5.75% is added on.

This will be:

Answer:

y = -0.5x + 7

Step-by-step explanation:

Equation of a Line is y = mx + c

where m is the slope and c is the y-intercept

Given two lines are Perpendicular

Then [tex]m_{1} m_{2} =-1[/tex]

So we given Line whose Equation is y = 2x +8

Then [tex]m_{1} =2[/tex] (Coefficient of x)

Since the Line we want is Perpendicular to that line

Then [tex]m_{1} m_{2} =-1[/tex]   ,  [tex]2m_{2} =-1 , m_{2} =\frac{-1}{2}[/tex]

So the Equation of the required Line is y = -0.5x +c

Since the Line passes through (2 , 6) , Then y = 6 when x = 2

By substitution , 6 = -0.5*2 + c  ,   6 = -1 + c

Then c = 6+1 =7

Then the Equation will be y = -0.5x + 7

Answer:   y= -1/2x+7

Step-by-step explanation: use the point slope form and use the -1/2x like the slope because the perpendicular lines are negative reciprocals.
