When a nursery owner orders plants from the distributor, 92% of the plants arrive alive. If the nursery owner wants their inventory of a particular plant to be 540 living plants, how many plants should the owner order?

Answer:

Option B (3x - 4y = -4).

Step-by-step explanation:

Parallel lines are the straight lines that never meet. This is only possible when the gradients of both the lines are same. This means that the slopes of all the parallel lines in a group can be calculated by calculating the slope of one of the lines. Therefore, the slope of the line that is parallel to the line 3x-4y=7 is the same as the original line. Hence, the gradient can be extracted from the original line by converting the equation in the form y=mx+c, where m is the slope.

3x - 7 = 4y.

y = (3/4)x - 7/4.

The slope of the line which has to be found is 3/4 and it passes through (x0, y0) = (-4, -2). Using the following formula:

(y - y0) = m*(x - x0).

(y + 2) = (3/4)*(x + 4)

Cross multiplying:

4y + 8 = 3x + 12.

3x - 4y = -4.

Hence, Option B is the correct choice!!!

Answer:

3.6

Step-by-step explanation:

replace x with -3

f(-3)=0.6(3-(-3))

f(-3)=0.6(6)

f(-3)=3.6

Answer:

3.6.

Step-by-step explanation:

Replace x by -3 in the function and work it out:

f(-3) = 0.6(3 - (-3))

= 0.6(3 + 3)

= 0.6*6

= 3.6 (answer).

x/-9 ≥ 3

To solve for x, multiply both sides by -9

x ≥ 3 *-9

Because the number is negative reverse the inequality sign.

x ≤ -27

the answer is A. the commutative property of addition. this property states that no matter what order you put the numbers, the outcome will be the same.

Hope this helps!

Answer:

The solution of the system of equations are the points (1,2) and (-1,-2)

a0=1, a1=-1,a2=-2

Step-by-step explanation:

we have

[tex]x^{2} +y^{2}=5[/tex] ----> equation A

This is the equation of a circle centered at the origin

[tex]y=2x[/tex] ----> equation B

This is the equation of a line, that passes through the origin (a direct variation)

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection points both graphs

using a graphing tool

The intersection points are (1,2) and (-1,-2)

see the attached figure

therefore

The solution of the system of equations are the points (1,2) and (-1,-2)

a0=1, a1=-1,a2=-2

Answer:

We need to find the increasing function with constant slope.

Let us check each option one by one.

A) 6x -5y =10.

Let us solve it for y to get slope-intercept form

6x-5y =10.

-5y =-6x +10.

y =6/5 x-2.

Slope is 6/5 positive, therefore, it's an increasing function.

A linear function always has a constant slope.

Therefore, correct option is option A.

A. 6x -5y =10

All other options are incorrect.

Answer:

300+85670=85970

Answer:

85,970

Step-by-step explanation:

This is simple, just add 300 or 3 hundreds to 85,650 on a calculator to get 85,970. 6 + 3 = 9.

Answer:

see explanation

Step-by-step explanation:

Note that 9x² and 49y² are perfect squares.

9x² = (3x)² → 3x is the first term

49y² = (7y)² → 7y is the second term

Hence

(3x + 7y)² = 9x² + 42xy + 49y²

Answer:

[tex] \frac{3}{x - 3} - \frac{5}{x - 2} = \frac{3(x - 2) - 5(x - 3)}{(x - 3)(x - 2)} = \frac{3x - 6 - 5x + 15}{(x - 3)(x - 2)} = \frac{9 - 2x}{(x - 3)(x - 2)} [/tex]

To simplify the expression 3/x-3 - 5/x-2 into one fraction, you need to find a common denominator. The simplified expression is (-2x+9) / [(x-3)(x-2)].

To simplify the expression 3/x-3 - 5/x-2 into one fraction, we need to find a common denominator.

The denominator of the first fraction is x-3 and the denominator of the second fraction is x-2.

The common denominator will be (x-3)(x-2) since that is the product of the two denominators.

Multiplying the numerator and denominator of the first fraction by (x-2) and the numerator and denominator of the second fraction by (x-3), we get:

[(3)(x-2)] / [(x-3)(x-2)] - [(5)(x-3)] / [(x-3)(x-2)]

= (3x-6) / [(x-3)(x-2)] - (5x-15) / [(x-3)(x-2)]

Now that we have a common denominator, we can combine the terms in the numerator:

(3x-6 - 5x+15) / [(x-3)(x-2)] = (-2x+9) / [(x-3)(x-2)]

Therefore, the simplified expression is (-2x+9) / [(x-3)(x-2)].

Answer:

A. Down on the left, down on the right

Step-by-step explanation:

Let x be negative infinity

f(-∞) = -3 (-∞)^4+ 7(-∞)^2 - 12(-∞) + 13

f(-∞) = -3 (∞)^4+ 7(∞)^2 + 12(∞) + 13

The term that dominates is ∞^4

That term is negative because of the -3, so it goes down

f(∞) = -3 (∞)^4+ 7(∞)^2 - 12(∞) + 13

f(∞) = -3 (∞)^4+ 7(∞)^2 - 12(∞) + 13

The term that dominates is ∞^4

That term is negative because of the -3, so it goes down

It is down at -∞ and down and +∞

The end behavior of the function is determined by the sign of the leading coefficient and the degree of the highest-powered term. Since the leading coefficient for f(x) = -3x^4 + 7x^2 - 12x + 13 is negative and the degree is even, it results in a down on the left, down on the right end behavior.

To determine the end behavior of a polynomial function, like f(x) = -3x^4 + 7x^2 - 12x + 13, you look at the coefficient and degree of the highest-powered term. The highest-powered term in the function is -3x^4.

Since the highest degree of the function is even (4), the arms of the graph will go in the same direction. That direction is determined by the sign of the leading coefficient, which is negative in this case. Therefore, the end behavior of f(x) is: Down on the left, down on the right.

So, the correct answer is Option A.

Answer:

(1, - 6.75 )

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y + 6.75 = 0.25(x - 1) ← is in point- slope form

with m = 0.25 and (a, b) = (1, - 6.75) ← point on line

Answer:

(1, - 6.75 )

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y + 6.75 = 0.25(x - 1) ← is in point- slope form

with m = 0.25 and (a, b) = (1, - 6.75) ← point on line

Answer:

x ≥ 6

Step-by-step explanation:

Lets solve the first inequality:

7x - 6 > 8

7x > 8 + 6

7x > 14

x > 14/7

x > 2

And now the second inequality:

3x + 4 ≥ 22

3x ≥ 22 - 4

3x ≥ 18

x ≥ 18/3

x ≥ 6

So, from the 2 answers, which region is overlapping ?? x ≥ 6

So this is the solution.

Note: we disregard x from 2 to 6 because that region is ONLY solution to the first one

The answer is:

The function intercepts de x-axis at "x" equal to 1.631.

To find the x-intercept of the function, we need to make f(x) or "y" equal to 0, and then, isolate "x".

So, isolating we have:

[tex]f(x)=3^{(x-1)} -2\\\\0=3^{(x-1)} -2\\\\3^{(x-1)}=2\\\\Log_{3}(3^{(x-1)})=Log_{3}(2)\\\\x-1=0.631\\\\x=0.631+1=1.631[/tex]

Hence, we have that the function intercepts de x-axis at "x" equal to 1.631.
