is the number 27 prime composite or neither​

Answer:

5

Step-by-step explanation:

we can write the digits in following form

0+1-2+3-4+5-6+7-8+9

= -1 - 1 -1 -1 +9

=-2-2+9

= -4+9

= 5

Answer:

Yes, it is linear. y=-1/2x+3/4

Step-by-step explanation:

To put it in standard form, you need to get the y by itself.

4y=-2x+3

Divide by 4.

y=-1/2x+3/4

Answer:

5/2 or 2.5

Step-by-step explanation:

Slope formula:

(y₂ - y₁) / (x₂ - x₁)

Two points are given:

(2, 5) and (6, 15)

x₁ = 2

y₁ = 5

x₂ = 6

y₂ = 15

Substitute and solve:

(15 - 5) / (6 - 2)

10 / 4

5/2 or 2.5

Answer:

21 and 9 are the numbers

Step-by-step explanation:

check by doing 21 minus 9, they also add into 30 together. if you haven't already figured it out.

Answer:

C

Step-by-step explanation:

He is already 4 m away from the burrow and the plant is 6 meters away the plant is the goal and each hop brings him 0.4 closer so you would multiply 0.4 by the amount of hops and add 4 and it should equal 6 ex: 4+0.4h=6

if you where to solve for h you would get the amount of hops you need. hope this was helpful :D

Answer:

x^2+4y^2-8x+8y+4=0

Step-by-step explanation:

The general form of the given ellipse is x² +4y² - 8x + 8y + 4 = 0.

An ellipse can be defined as a shape that looks like an oval circle.

The equation of an ellipse is

[tex]\dfrac{\left(x - h\right)^{2}}{a^{2}} + \dfrac{\left(y - k\right)^{2}}{b^{2}} = 1[/tex]

Where (h, k) is the center a and b are the lengths of the semi-major and the semi-minor axes.

The vertices of an ellipse are (0,-1) and (8,-1).

The endpoints of the minor axis are (4,1) and (4,-3).

The following equations take into account the different properties of an ellipse:

[tex]k = -1k=−1, h^{2} = a^{2}h 2 =a 2 , \left(h - 8\right)^{2} = a^{2}[/tex]

[tex]\begin{cases} b = 2 \\ k = -1 \\ h^{2} = a^{2} \\ \left(h - 8\right)^{2} = a^{2} \end{cases}[/tex]

We get that h = 4 k = -1, a = 4, and  b = 2

The standard form of the given ellipse is

[tex]\dfrac{\left(x - 4\right)^{2}}{4^{2}} + \dfrac{\left(y + 1\right)^{2}}{2^{2}} = 1[/tex]

So the general form will be as : x² +4y² - 8x + 8y + 4 = 0.

Thus, the general form of the given ellipse is x² +4y² - 8x + 8y + 4 = 0.

Step-by-step explanation:

a triangle has a total of 180* so 180-40-37 will give yu the missing side which is 103

Answer: 1

From the second sentence, we have AB = BC = CD = DE = y. So AE = 4y and BD = 2y (you can see by drawing a diagram), and AE = 2BD. Substituting 2x + 3 for BD and 6x + 4 for AE in AE = 2BD, we have 6x + 4 = 2(2x + 3), 6x + 4 = 4x + 6. Solving, we see x = 1.

Please mark Brainliest if I am right.

Answer:

18.96 / 12 = 1.58

1.58 = the cost of 1 rose

1.58 X 5 = $7.9

Answer:

12 roses/18.86

12/18.96=5

this proportion is incorrect since the other side just says 5 and it needs to be in fraction form and have a variable as the numerator/denominator.

12/18.96=5/x

cross multiply

12x=18.96*5

12x=94.8

/12 both sides

x=7.9

$7.90

Answer:

A translation 9 units right

Step-by-step explanation:

Given

[tex]f(x) = 4x + 2[/tex]

[tex]g(x) = 4(x -9)+ 2[/tex]

Required

Translation of f(x) to g(x)

To do this, we take the options one after the other.

A translation 9 units right

When an original function f(x) is translated to the right by h points, the resulting function g(x) is

[tex]g(x) = f(x - h)[/tex]

So, we have that:

[tex]f(x) = 4x + 2[/tex]

When translated to the right by 9 points,

[tex]g(x) = 4(x - 9) + 2[/tex]

Hence, option A answers the question

Step-by-step explanation:

The solution to a system of equations given graphically is at the point of intersection of the 2 lines.

If the lines are parallel then there is no point of intersection thus no solution.
