Answer:

  (a)  (3x +1)(x +1)

Step-by-step explanation:

The values of the factors are represented by the horizontal and vertical dimensions of the area. In each direction, we have a "blue" dimension, and a "red" dimension.

Horizontally, we have a dimension of (3 × blue + 1 × red).

Vertically, we have a dimension of (1 × blue + 1 × red).

We can assign blue = 1, red = x, and we would have (3 +x)(1 +x). This does not match any answer choices.

We can also assign blue = x, red = 1, and we would have (3x +1)(x +1). This matches the first answer choice.

The product which is represented by the algebra tiles is (a)  (3x +1)(x +1)

This refers to the branch of mathematics where letters and symbols are used to represent numbers.

Hence, we can see that from the given image, there are different values which shows the horizontal and vertical dimensions of the area and from the:

Hence, if we represent the values of blue = 1, red = 1, then it would produce (3x +1)(x +1) and this is the correct answer.

Answer:

Reflection

Step-by-step explanation: A reflection is a transformation that acts like a mirror.

Answer:

Reflection

Step-by-step explanation:

Translations are a horizontal and/or vertical movement of a shape. In this case, the points wouldn't match up. A dilation is either growth or reduction, which this pretty obviously is not. A rotation also wouldn't properly match the points up. If we reflect this shape across a line directly in between the two, all the points will match up.

Option A is correct

Answer:

The poster is 11 inches wide and 19 inches in height.

Step-by-step explanation:

We take the given equation: (x^2+2x-15) and we add in 14 as our x variable:

((14)^2+2(14)-15) the answer we get from that is 209. The area of the poster is 209 square inches. Then we find the width by taking (x-3) in this case x is 14 so the width of the poster is 11. In order to find the height we divide the height by the width and we get 19.

Therefore:

Height= 19 Inches

Width= 11 Inches

Total Area= 209 Square Inches

Answer:

Let x represent the number of 2 pointers made.

Let y represent the number of 3 pointers made.

We have to create a system of equations to solve this problem:

Answer:

7/2 = 35/10

3/5 = 6/10

Step-by-step explanation:

To get a common denominator of 10, simply multiply the current denominator by any number to equal 10. The first fraction has a denominator of 2. If we divide 10 by 2, we get the answer 5. This means 2 can be multiplied by 5 to get a denominator of 10. However, what we do to the denominator we must also do to the numerator (multiply by 5).

Step-by-step explanation:

6(x-0,5) > 3
6x - 3 > 3
6x > 6
x> 1

Answer:

There are infinitely many solutions.

Step-by-step explanation:

So there are three possible scenarios. The is a finite set of solutions, there are infinitely many solutions, or there are no solutions.

We can determine which of these scenarios is possible by analyzing the pair of equations.

Y = (1/4)x - 1

Y = (1/4)(x - 4)

For clarity, I have put parentheses around the fractional component 1/4.

Note, the first equation can be rewritten as such:

Y = (1/4)x - 1

Y = (x/4) - 1

And the second equation can be simplified using the distributive property of multiplication

Y = (1/4)(x - 4)

Y = (1/4)x - (1/4)(4)

Y = (x/4) - (1)

Y = (x/4) - 1

Notice, both equation are actually the same. This means whatever values of x or Y you put in, the two equations will always be equal. This means there are infinitely many solutions because there are an infinite combination of x and Y that solve pair of equations given, which is actually the same equation. In the graph, this is represented as a line on top of the existing line.

Step-by-step explanation: (-16,1),(-6,5),(4,1), and (-6,3)

Here , we are given with a circle on cartesian plane , and we need to find the equation of the circle , We are also given that it's centre is at (5,-6) { From graph } and it's radius is 3 units . Now , as we know, the standard equation of a circle is [tex]{\bf (x-h)^{2}+(y-k)^{2}=r^{2}}[/tex] where (h,k) is the centre of the circle and radius is r . Now , our equation will be ;

[tex]{:\implies \quad \sf (x-5)^{2}+\{y-(-6)\}^{2}=3^{2}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{(x-5)^{2}+(y+6)^{2}=9}}}[/tex]

This is the required equation of Circle

Or if you want to proceed it further , then you will get x² + y² - 10x + 12y + 50 = 0

Answer:

$4.95

Step-by-step explanation:

If three people have $1.65 each, to find out how much money they have all together, you just multiply $1.65 by 3 (or add $1.65 3 times)

1.65 x 3 = 4.95

So all together, they have $4.95.

I hope this helps!

Answer:

Altogether they have 4.95$

Step-by-step explanation:

Giana, Kemi, and Matava are three people who each have 1.65$. So if they all combine it they will have 3×1.65$ which is =4.95$.

Step-by-step explanation:

Answer:

so basically you have to multiply all the numbers and divide by 2 and the rest is self explanatory

Answer:

It would be A

Step-by-step explanation:

The other answers do not make sense.

First of all: Area= length x width.

Two of the options were larger than 49.7, so we could cross those out

Then, we look at A and B.  

46.2 x 3.5 = 161.7, which is WAY larger than 49.7.

Since we have no option left to test, we can test A:

14.2 x 3.5= 49.7

Now we cam be sure that the answer is 14.2, or, A.

4x = 161

x=40.25

Question 3

4(2z + 3) = 12

8z +12 = 12

8z = 0

z = 0

Question 4

5(2x − 6) + 20 = 10

10x-30+20=10

10x-10=10

10x =20

x=2
