Answer:

The first step is A. Subtraction

The second steep is D. Division

Step-by-step explanation:

The first step was done in other to remove the constant at one end of the equality that was with the variable, it was done in order to eradicate the constant and isolate the variable to make the equation easier to solve.

The second step was done in order to remove the coefficient of the variable so as the variable to be on it's own as x alone.

These two steps were just followed in order to find the value of the variable.

Answer:

The first step is to combine the constant terms by using the (B.) subtraction property of equality.

The second step is to use the (D.) division property of equality to isolate the variable.

3. Formulate 900 lbs of a 35% CP ration using Soybean Meal (46% CP) and Oats (12% CP). How many pounds of soybean meal will be u

Anarel [89]

Answer:

The amount of Soyabean = 608.82 pounds.

The amount of Oats = 900-608.82 = 291.18 pounds.

Step-by-step explanation:

Given that the Soybean Meal has 46% CP and Oats has 12% CP.

The total amount of ration is 900 lbs of 35% CP.

Let x pounds of Soyabean has been used, so,

the amount of Oats = 900-x lbs.

The CP amount in 900 lbs mixture will be equal to the sum of CP amounts in x lbs Soyabean and 900-x lbs Oats, i.e

35% of 900 = 46% of x + 12% of (900-x)

$\Rightarrow \frac{35}{100}\times 900=\frac{46}{100}\times x+\frac{12}{100}\times (900-x)$

$\Rightarrow 35\times 900 = 46x + 12\times 900 - 12 x$

$\Rightarrow 34x= 900(35-12)$

$\Rightarrow x = (900\times 23)/34$

$\Rightarrow x = 608.82$ lbs.

So, the amount of Soyabean = 608.82 pounds.

The amount of Oats = 900-608.82 = 291.18 pounds.

The relationship between the slopes of two lines that are parallel is _____________.

a_sh-v [17]

They are the same slope

they are negative inversees (they multily to get -1)

2

-1/2

use the square viewer (on TI)

The relationship between the slopes of two lines that are parallel is they are the same. The relationship between the slopes of two lines that are perpendicular is they are negative inverses of each other (they multiply to -1).
A line that is parallel to a line whose slope is 2 has slope 2.
A line that is perpendicular to a line whose slope is 2 has slope -1/2.

What must be done to make the graphs of two perpendicular lines appear to intersect at right angles when they are graphed using a graphing utility?

Find the length of the side marked x

ruslelena [56]

it's a right angled triangle so we will use hypotenuse formula to get the value of x

hypotenuse formula = a² + b² = c²

a = side of the triangle

b = base of traingle

c = hypotenuse ( can be written as h too)

and the formula can also be written as.

c² = a² + b²

therefore, x = 12.1

hope this answer helps you dear...take care!

For each table, determine whether it shows that x and y are proportional.

myrzilka [38]

9514 1404 393

Answer:

1. proportional, 6

2. not proportional

Step-by-step explanation:

Table 1

Each y-value is 6 times the corresponding x-value, so the variables are proportional, and y = 6 times x.

Table 2

The ratios of y to x are 2, 4, 8, so are not the same. The values are not proportional.
