Step-by-step explanation:

I got this from Khan Academy and thatcrabb1772.

Answer:

Step-by-step explanation:

t5 = a + (5-1)d

t5 = a + 4d

40 = a + 4d

t3 = a + 2*d

t7 = a + 2d + 28 = a + 6d

Start with the seventh term which has 2 equal answers

a + 2d + 28 = a + 6d                    Subtract a from both sides

2d + 28 = 6d                                Subtract 2d from both sides

28 = 4d                                         Divide by 4

28/4 = d

d  = 7

==================

t5 = a + 4d = 40

a + 4*7 = 40

a = 40 - 28

a = 12

===================

First term is 12

10th term is

t10 = 12 + (10 - 1)*7

t10 = 12 + 9*7

t10 = 75

Interesting question. Thanks for posting

Answer:

6

Step-by-step explanation:

2/7 = n/21

How I do it is:

1. I put it like this: n7=2 times 21

then I multiply 2 times 21 which is 42

2. then it becomes n7=42 which basically is 42/7 which is 6 so N=6

Hope this helped! Have a great day!

Answer:

[tex]\$18[/tex]

Step-by-step explanation:

Let the cost of sheet metal per square feet be [tex]x[/tex]

Amount of sheet metal bought is [tex]10.8\ \text{ft}^2[/tex]

Amount of sheet metal used is [tex]3.7\ \text{ft}^2[/tex]

Remaining value of the sheet metal is [tex]\$127.8[/tex]

So we get the equation

[tex]10.8x-3.7x=127.8\\\Rightarrow 7.1x=127.8\\\Rightarrow x=\dfrac{127.8}{7.1}\\\Rightarrow x=18[/tex]

So, cost of sheet metal per square feet is [tex]\$18[/tex].

Answer:

1. x = 8

2. y = 1/2

Step-by-step explanation:

1. Plug the function

5x + 20(0.50) = 50

= 5x + 10 = 50

Subtract 10 from both side

= 5x = 40

Divide 5 on both sides

= x = 8

2. Plug in the function

5(8) + 20y = 50

= 40 + 20y = 50

Subtract 40 on both sides

= 20y = 10

Divide 20 both sides

= y = 10/20 | 1/2

Answer:

1. 8

Explanation: 5x + 20(.50)=50

5x + 10=50. Now do 50-10 to get 40. So,

5x=40. Now divide 40/5 to get 8.

2. .5

5(8) + 20x=50. Now do 5*8

40 + 20x=50. Now, 50-40 to get

20x=10. And divide 10/20 to get .5

Answer:

x=2

Step-by-step explanation:

Hi there! what we have here is something call a corresponding angle. Which means that even though they are not on the same like they are still equal. in order to find the x in the problem you would have to make an equation: 7X+3=8x+1

now its time to solve.

1) add the like terms together on the same side

1-3=8x-7x

2) simplify

x=2

The correct option is;

d. Reflecting about the line y = -1, followed by translating 8 units to the right

Step-by-step explanation:

The coordinates of the vertices of the banner Jane created = A(-4, 3), B(-1, 5) and C(-1, 2)

By reflecting across the line y = -1, we get

A(-4, 3) by reflection across the line y = -1 gives A(-4, -5)

B(-1, 5) by reflection across the line y = -1 gives B(-1, -7)

C(-1, 2) by reflection across the line y = -1 gives C(-1, -4)

By translating 8 units to the right get

A(-4, 3) by translation 8 units right gives A prime (4, -5)

B(-1, 5) by translation 8 units right gives B prime (7, -7)

C(-1, 2) by translation 8 units right gives C prime (7, -4)

Therefore, the two transformation that she could perform so that the transformed vertices become A prime (4, -5), B prime (7, -7), and C prime (7, -4) are;

1) Reflection across the line y = -1

2) An horizontal translation 8 units to the right get.

Transformation involves changing the size and position of a shape.

The sequence of two transformations are: (d). reflecting about the line y = -1, followed by translating 8 units to the right

The coordinates of ABC are given as:

[tex]\mathbf{A =(-4,3)}[/tex]

[tex]\mathbf{B =(-1,5)}[/tex]

[tex]\mathbf{C =(-1,2)}[/tex]

First, the coordinates of ABC are reflected across the line [tex]\mathbf{y =-1}[/tex]

The transformation rule is:

[tex]\mathbf{(x,y) \to (x,-y -2 \times 1)}[/tex]

So, we have:

[tex]\mathbf{A' = (-4,-3 -2 \times 1)}[/tex]

[tex]\mathbf{A' = (-4,-5)}[/tex]

[tex]\mathbf{B' =(-1,-5 - 2 \times 1)}[/tex]

[tex]\mathbf{B' =(-1,-7)}[/tex]

[tex]\mathbf{C' =(-1,-2 -2 \times 1)}[/tex]

[tex]\mathbf{C' =(-1,-4)}[/tex]

Next, the shape is translated 8 units right.

The rule of this transformation is:

[tex]\mathbf{(x,y) \to (x + 8, y)}[/tex]

So, we have:

[tex]\mathbf{A" = (-4 + 8, -5)}[/tex]

[tex]\mathbf{A" = (4, -5)}[/tex]

[tex]\mathbf{B" =(-1+8,-7)}[/tex]

[tex]\mathbf{B" =(7,-7)}[/tex]

[tex]\mathbf{C" =(-1+8,-4)}[/tex]

[tex]\mathbf{C" =(7,-4)}[/tex]

Hence, the sequence of two transformations are:

(d). reflecting about the line y = -1, followed by translating 8 units to the right

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

By reasoning, we can say 50% of 200 is 100

We can say 10% of 200 is 20

We divide 20 by 2 to get 5%

20/2

= 10

Subtract 100 by 10

100 - 10

= 90

45% of 200 is 90

First, we must find the slope of the line using slope formula*.

[tex]m = \frac{-5 - 1}{-4 - 4} = \frac{-6}{-8} = \frac{3}{4}[/tex]

Second, we now find the y-intercept, or b, using slope-intercept form, the slope we found, and one of the given points.

[tex]1 = \frac{3}{4}(4) + b\\\\1 = 3 + b\\\\-2 = b[/tex]

Lastly, we can now create the equation of the line.

The equation of the line that goes through the given points is C. [tex]y = \frac{3}{4}x - 2[/tex]

Answer:

The polynomial is x^3-x^2-33x+63

Step-by-step explanation:

Here, we want to find a polynomial of degree 3 with the given roots

-7 with a multiplicity of 1 and 3 with a multiplicity of 2

if x = -7

x + 7 is a root

if x = 3

x -3 is a root

Since the multiplicity of this is 2, we have x-3 twice

The complete polynomial is;

(x-3)(x-3)(x+7)

= x^2-6x+9(x + 7)

= x(x^2-6x+9) + 7(x^2-6x+9)

= x^3-6x^2 + 9x+7x^2-42x+63

= x^3-x^2-33x+63
