slope of 1?

**Answer:**

y =1x+4

**Step-by-step explanation:**

Explain why the product of a non-0 rational number and an irrational number is irrational?

**Answer:**

An irrational number is a number that can not be written as the quotient of two integer numbers.

Then if we have:

A = a rational number

B = a irrational number.

Then we can write:

A = x/y

Then the product of A and B can be written as:

A*B = (x/y)*B

Now, let's assume that this product is a rational number, then the product can be written as the quotient between two integer numbers.

(x/y)*B = (m/n)

If we isolate B, we get:

B = (m/n)*(y/x)

We can rewrite this as:

B = (m*y)/(n*x)

Where m, n, y, and x are integer numbers, then:

m*y is an integer

n*x is an integer.

Then B can be written as the quotient of two integer numbers, but this contradicts the initial hypothesis where we assumed that B was an irrational number.

Then the product of an irrational number and a rational number different than zero is always an irrational number.

We need to add the fact that the rational number is different than zero because if:

B is an irrational number

And we multiply it by zero, we get:

B*0 = 0

Then the product of an irrational number and zero is zero, which is a rational number.

can someone plz help with this? geometry:)

**Answer:**

One property of rectangles is that the diagonals of rectangles bisect each other, meaning 2 of JN is equal to JL.

We can form an equation off of this, 2(x+3) = 3x + 1 and then solve for x

2(x+3)= 3x + 1 First, distribute the 2 to each term in x+3,

the result should be:

2x + 6 = 3x+ 1 then subtract 2x from both sides

-2x -2x

the result should be :

6 = x + 1 subtract 1 from both sides

-1 -1

the result should be x=5

plug that into the equations and JN= 5+3, JL=15+1

The two correct options are

NM = 8 ( both of the diagonals are equal to eachother )

JL = 16

**Step-by-step explanation:**

Find the value of y. Round your answers to the nearest tenth

**Answer:**

y ≈ 4.3

**Step-by-step explanation:**

Since the figures are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AB}{RS}[/tex] = [tex]\frac{ED}{VU}[/tex] , substitute values

[tex]\frac{6}{4}[/tex] = [tex]\frac{8}{y+1}[/tex] ( cross- multiply )

6(y + 1) = 32

6y + 6 = 32 ( subtract 6 from both sides )

6y = 26 ( divide both sides by 6 )

y ≈ 4.3 ( to the nearest tenth )

**Answer:**

4.3 Is the answer like the value of X in the nearest tenth.

A type of fish for your aquarium costs $7 each. You can spend at most $56. How many of these fish can you buy? Write an inequality to model the problem. Then solve the inequality to find the number of fish.Over the next 13 months you have to read more than 65 books. You have to read x books per month. The inequality 13x>68represents this situation. Solve the inequality to find the number of books you have to read per month.

**Answer:**

**x <= 8 ** ... you can buy a max of 8 fishes

**6 books or more per month**.

**Step-by-step explanation:**

Given the information provided, we can create the following inequality which multiplies the cost per fish ($**7**) by the number of fish we can buy (**x**) and it has to be less than or equal to **$56**

**7x <= 56**

We can now solve this inequality by isolating x

**7x <= 56 ** ... divide 7 on both sides

**x <= 8** ... you can buy a max of 8 fishes

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

**13x > 68** ... divide both sides by 13

**x > 5.23**

Since the number of books needs to be a whole number then we round this decimal up to 6. Meaning that you must read **6 books or more per month**.

Write the slope-intercept form of the equation of each line.

**Step-by-step explanation:**

you look at how the line intersects with an integer point.

on the y-axis, the line has a value of -2 so it has a y-intercept value of -2

so the slope formula is rise/run.

As we can see on the graph, there is no line on the graph that truly lines up with a point besides (0,-2)

if we look at all of the slopes

from A,B,C, and D, and there are not any slopes besides d that are on the graph.

y=mx+b

m=slope

b=y-intercept

If we expand the graph a little bit we can see that the point (0,-2) goes up 7 and goes to the left of 4 units.

so the answer is D : y=-7/4x-2

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

and since we go up and to the left or we go down and to the right that determines that the slope is negative.

If we started on a point on the y-axis, and started and went up and to the right or down and to the left.

Hope that helps :)

6.A = 23 × 3 × 5 B = 22 × 3 × 52

Write down the highest common factor (HCF) of A and B.Required to answer. Single line text.

(1 Point)

**Given:**

The two numbers are

[tex]A=23\times 3\times 5[/tex]

[tex]B=22\times 3\times 52[/tex]

**To find:**

The highest common factor (HCF) of A and B

**Solution:**

We have,

[tex]A=23\times 3\times 5[/tex] ...(i)

[tex]B=22\times 3\times 52[/tex]

All the factors of A are prime but the factors of B are not prime. So, it can be written as

[tex]B=2\times 11\times 3\times 13\times 2\times 2[/tex] ...(ii)

From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,

[tex]HCF(A,B) = 3[/tex]

**Therefore, the highest common factor (HCF) of A and B is 3.**

A triangle was translated 4 units down.

In the graph, which figure is the pre-image and which

figure is the image?

O AFGH is the image and A ABC is the pre-image

AFGH is the pre-image and AABC is the image.

Both triangles are images.

The image cannot be determined from the graph.

**Given:**

A graph that contains image and preimage.

**To find:**

Which figure is the preimage and which figure is the image.

**Solution:**

Initial figure is known as preimage and translated figure is known as image.

It is given that a triangle was translated 4 units down. It means, the upper triangle is preimage and the lower triangle is the image.

So, ΔFGH is the pre-image and ΔABC is the image.

**Therefore, the correct option is B.**

the answer is B :0

i got it right on my assignment !!!!

I need help ASAP!!!!!!

**Answer:**

1. YES 2. NO

**Step-by-step explanation:**

1. Since x=0.121212... and the question is asking for 100x, we need to multiply each side by 100. 0.121212... multiplied by 100 is 12.1212... So YES, 100x is still a repeating decimal.

2. 12.121212... minus 0.121212... would just be 12. This is because if we know that all the numbers behind the decimal point is 0.121212 and so on, 12.121212... minus 0.121212... the numbers behind the decimal would cancel out. So we are left with 12. So NO, the answer for 99x is NOT a repeating decimal.

How do i find this slope?!?!?!

The slope is 3/4 because it is 3 units up and then 4 units to the right.

**Answer:**

**Step-by-step explanation:**

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

Here are the equations you can use to find the slope;

Slope. y2 - y1 / x2 - x1 = slope.

Slope Intercept form. y = mx + b.

Point slope form. y - y1 = m ( x - x1)
