Can u make the picture any bigger?

Step-by-step explanation:

Answer:

1 and 2

Step-by-step explanation:

If x is 1: 2 x 1 + 7 = 2 + 7

= 9  This works.

If x is 2: 2 x 2 + 7 = 4 + 7

= 11  This works

If x is 3: 2 x 3 + 7 = 6 + 7

= 13  This does not work since 2x + 7 has to be less than 13.

Answer:

40%

Step-by-step explanation:

There are five pieces of a square.  Two of the five pieces are shaded in orange, since each piece is 20% and there are two shaded pieces, it is your best bet that your final answer is 40%.

Answer:

40%

Step-by-step explanation:

Since there are only two boxes filled, the fraction would be 2/5. Now, by applying that knowledge, you can see that the bow is filled 40% of the way with orange. An easy way to figue this out would be to divide 2 by 5 and get the decimal of .4 which as a percentage would be 40%. Hope this helped!

Answer:

x = 5

Step-by-step explanation:

[tex]\frac{x}{2x - 3} = \frac{10}{14}[/tex] --> Triangle Proportionality Theorem

10(2x - 3) = 14(x) --> Cross Multiplying

20x - 30 = 14x --> Distributing 10 and 14 to the parentheses

20x -30 - 14x + 30 = 14x - 14x + 30 --> Subtracting 14x and adding 30 on both sides

6x = 30 --> Simplifying

6x/6 = 30/6 --> Dividing 6 on both sides

x = 5 --> Simplifying

Hope this helped!

By the way, I'm not so sure you understand the concept of "Triangle Proportionality Theorem" since you asked a similar one before that. So I'll post an image that I found on the internet that explains it. :D

Answer:

Having done everything in his power to secure American independence, Washington decided to retire “from all public employments” after the war. He found true peace back at Mount Vernon and was happy to “move gently down the stream of life until I sleep with my fathers.” Washington’s joyful retirement was interrupted in 1787 when his country called on him again.

Step-by-step explanation:

Answer:

L= 11m

W= 7m

Step-by-step explanation:

Step one:

given data

Let the width W= x

Length = (2x-3)

P= 36 m

Required

The perimeter

P= 2L+2W

36= 2(2x-3)+ 2x

36= 4x-6+2x

collect like terms

36+6= 6x

42= 6x

divide both side by 6

x= 7

the width is 7 m

the length = 2x-3= 2*7-3= 14-3= 11 m

Answer:

this table is exponential

Step-by-step explanation:

the way we can tell this is because we can find a common ratio of 4. we know this because linear tables have a common difference exponential tables have a common ratio. i found this answer by dividing 32,768 and 8,192

32,768/8,192 = 4

you can find a linear function by subtracting point 1 and point 2.

Answer:

  B (rate of change), D (y-intercept)

Step-by-step explanation:

a) The rate of change is found by solving for y. It is the x-coefficient:

  4y = -x +12

  y = -1/4x +3 . . . . divide by 4

The rate of change is -1/4.

__

b) The rate of change can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (10 -4)/(2 -(-2)) = 6/4 = 3/2

The rate of change is 3/2.

__

c) The rate of change can be found by counting grid squares. The line goes down 1 square for each square to the right. The rate of change is ...

  m = rise/run = -1/1 = -1

The rate of change is -1.

__

d) The rate of change is 0.5, the amount paid per box.

__

Of the rates -1/4, 3/2, -1, 0.5, the largest rate of change is 3/2 in relationship B.

_____

a) The y-intercept is the constant in the slope-intercept form equation: +3.

__

b) The y-intercept can be found from the point-slope form equation using the slope we found.

  y -4 = 3/2(x +2)

  y = 3/2x +3 +4

  y = 3/2x + 7

The y-intercept is 7.

__

c) The y-intercept is 4, where the line crosses the y-axis.

__

d) The y-intercept of a proportion is 0.

__

Of the y-intercepts 3, 7, 4, 0, the least y-intercept is 0, in relationship D.

[tex]h=4x^3+18[/tex]

Step-by-step explanation:

Given that,

The area of a triangle, [tex]A=14x^5 + 63x^2[/tex]

Base, [tex]b=7x^2[/tex]

We need to find the height of the triangle.

The formula for the area of the triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times h\\\\\text{h is height}\\\\h=\dfrac{2A}{b}\\\\h=\dfrac{2\times (14x^5 + 63x^2)}{7x^2}\\\\h=\dfrac{2\times 7x^2(2x^3 + 9)}{7x^2}\\\\h=2(2x^3+9)\\\\=4x^3+18[/tex]

So, the height of the triangle is [tex]4x^3+18[/tex].

Answer:

m = 20.2; n = 10.4

Step-by-step explanation:

[tex]\left \bigg \{ { \big {3m + n = 71} \atop \big {2m - n = 30}} \right.; => \left \bigg \{ { \big {3m + n -3m= 71-3m} \atop \big {2m - n-2m = 30-2m}} \right.; => \left \bigg \{ { \big { n = 71-3m} \atop \big { - n = 30-2m}} \right. ; => \\\\=> \left \bigg \{ { \big { n = 71-3m} \atop \big { - n \times (-1) = (30-2m)\times (-1)}} \right.; =>\left \bigg \{ { \big { n = 71-3m} \atop \big { n = -30+2m}} \right..[/tex]

-30 + 2m = 71 - 3m

-30 + 2m + 30 = 71 - 3m + 30

2m = 101 - 3m

2m + 3m = 101 - 3m + 3m

5m = 101

5m ÷ 5 = 101 ÷ 5

m = 20.2

n = 71 - 3m = 71 - 3 × 20.2 = 10.4
