Step-by-step explanation:

Given

3x + 5 = 2y

Writing in slope intercept form

y = (3x + 5) / 2

y = 3/2 x + 5/2

Hope it will help :)

Answer:

[tex]\text{D. The terms may be combined.}[/tex]

Step-by-step explanation:

Recall that [tex]\sqrt{a\cdot b}=\sqrt{a}\cdot\sqrt{b}[/tex]. Using this, we can simplify and combine the two terms:

[tex]6\sqrt{32}-12\sqrt{72},\\=6\cdot \sqrt{4}\cdot \sqrt{8}-12\cdot \sqrt{9}\cdot \sqrt{8},\\=6\cdot 2\cdot \sqrt{8}-12\cdot 3\cdot \sqrt{8},\\=12\sqrt{8}-36\sqrt{8},\\=-24\sqrt{8}=-24\cdot\sqrt{4}\cdot\sqrt{2}=\boxed{-48\sqrt{2}}[/tex]. Therefore, the terms may be combined.

Answer:

We have a total of 7200 plants.

The plants are distributed in one field with 18 rows of 200 plants and another field with 9 rows of N plants.

Where we want to find the value of N.

The total number of plants in the rows is:

"number of rows times number of plants in each row."

Then the total number of plants is:

18*200 + 9*N

And we know that we have a total of 7200 plants, then:

18*200 + 9*N = 7200

9*N = 7200 - 18*200 = 3600

N = 3600/9 = 400

Then the plants are distributed in 18 rows of 200 plants for one field, and 9 rows of 400 plants in the other field.

Answer:

y-9=-5/2(x+6)

Step-by-step explanation:

y-y1=m(x-x1)

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

An equation in point-slope form for this line would be y-9=-5/2(x+6).

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Which is the required equation of a line in a point-slope form.

Thus,

y-y1= m(x-x1)

A line passes through the point (-6,9) and has a slope of -5/2 So,

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

Hence, an equation in point-slope form for this line would be y-9=-5/2(x+6).

The answer is -5

Step-by-step explanation:

First, let's understand about what are rational number and Integer.

Both rational and Integer are part or rather say subset of Real Number. Real Number can be broken into these categories:

I will not talk about Irrational since It is a bit off-topic for the question.

Rational can be broken into:

Integer is a subset of Rational Number and Real Number. But what is really Integer?

Integer is a whole number or any numbers that don't have decimal, fraction. Integer can be ...,-4,-3,-2,-1,0,1,2,3,4,...

The three dot symbol refers to being endless or countable infinity.

Now that you see Integer cannot be fraction, decimal.

Therefore, the answer is -5

Answer: B) -5

Step-by-step explanation:

An integer is like a whole number, but it also includes negative numbers (e.g. -300, -5, 0, 5, 6, 100).

You can write a rational number as a ratio of two numbers (e.g. 7/1, 1/3, -2/3, -4/7).

None of the answer choices given are integers, except -5. It is also a rational number, since it can be written as -5/1.

The given vector is:

v = -5i+9j

We need to find the angle of this vector.

The angle of this vector form is given by :

[tex]\tan\theta=\dfrac{y}{x}\\\\\tan\theta=\dfrac{9}{-5}\\\\\tan\theta=-1.8\\\\\theta=\tan^{-1}(-1.8)\\\\=-60.94^{\circ}[/tex]

Answer: 127.5km

Step-by-step explanation:

We are informed that Ron cycled 510km last week and that he was under the rain for the 25percent of his journey.

The distance travelled did under the rain will be gotten by multiplying 25% by 510km. This will be:

= 25% × 510

= 0.25 × 510

= 127.5km

He was in the rain for 127.5km

Answer:

first option

Step-by-step explanation:

In a parallelogram consecutive angle are supplementary, sum to 180, so

2a + 122 = 180 ( subtract 122 from both sides )

2a = 58 ( divide both sides by 2 )

a = 29

In a parallelogram the opposite sides are congruent, then

b + 6 = 10 ( subtract 6 from both sides )

b = 4

Answer:

3x^2 - 7x +4

Step-by-step explanation:

see step on the file joint

The quotient of 9x³ - 21x² + 12x divided by 3x is  3x² - 7x + 4.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, A cubic polynomial 9x³ - 21x² + 12x and being divided by 3x.

So, (9x³ - 21x² + 12x)/(3x).

= 9x³/3x - 21x²/3x + 12x/3x.

= 3x² - 7x + 4.

So, The quotient when 9x³ - 21x² + 12x and being divided by 3x is

3x² - 7x + 4.
