  an = 13 -5(n -1)

Step-by-step explanation:

The "take away 5" rule means the common difference between terms is d=-5. For first term a1=13, the n-th term is ...

  an = a1 +d(n -1)

  an = 13 -5(n -1)

Answer:

9/8 of a bag

she doesn't have enough beads.

Step-by-step explanation:

Bag of bead poppy has = 1

Bag of bead needed for necklace 1 = 3/8 of a bag

Bag of bead needed for necklace 2 = 1/8 of a bag

Bag of bead needed for necklace 3 = 5/8 of a bag

Total bag of beads needed = 3/8 + 1/8 + 5/8

= (3+1+5)/8

= 9/8

She needs 9/8 of a bag of bead

9/8 = 1 1/8

Therefore, she doesn't have enough beads.

Answer:

∠S = 151°

Step-by-step explanation:

Hello there!

This is an irregular pentagon

If you didn't know the sum of the interior angles add up to equal 540

We must solve for x to be able to find the measure of angle S

we can use this equation to solve for x

540 = 5x + 2 + 10x - 3 + 7x - 11 + 13x - 31  + 8x - 19

step 1 combine like terms

2 - 3 - 11 - 31 - 19 =-62

5x + 10x +7x + 13x + 8x = 43x

so now we have

540 = 43x - 62

step 2 add 62 to each side

-62 + 62 cancels out

540 + 62 = 602

now we have

602 = 43x

step 3 divide each side by 43

43x/43 = x

602/43=14

we're left with x = 14

Now we want to plug in x for angle S

13(14) - 31

13*14=182

182-31=151

So we can conclude that the measure of angle S is 151 degrees

Step-by-step explanation:

y = 6x-11

substitute y into 2x+3y=7

2x+3(6x-11)=7

2x + 18x-33 = 7

20 x = 7+33

x = 2

y?

y= 6(2)-11

y = 12-11 = 1

so, x = 2 and y = 1

Answer:

x = 9

m∠1 = m∠2 = 54°

Step-by-step explanation:

Two lines r and s are the parallel lines and a transversal line is intersecting these lines at two distinct points.

a). ∠1 ≅ ∠2 [Corresponding angles]

    Therefore, m∠1 = m∠2

    (63 - x)° = (72 - 2x)°

    2x - x = 72 - 63

    x = 9

b). m∠1 = (63 - x)°

            = 63 - 9

            = 54°

    m∠2 = (72 - 2x)°

             = 72 - 18

             = 54°

Answer:

2 should be added to the data

Step-by-step explanation:

Hope this helps!

If im wrong im sorry!

Answer:

18 should be added

Step-by-step explanation:

So we have one 10 and one 11 in this data set, and we need to figure out which number we need to add to get a mean of 13

let's make this unknown number x

to find the mean, we add up all the values of the numbers on the data set, and divide it by how many numbers we have.

we have 3 numbers, and our numbers are 10, 11, and x. When we add 10, 11, and x together, and then divide by 3, the value is 13

as an equation we will have:

(10+11+x)/3=13

combining like terms in the numerator, it will be:

(21+x)/3=13

We need to solve this equation, and the denominator of 3 just makes harder to do that.

Clear the fraction by multiplying both sides by 3

21+x=39

subtract 21 from both sides

x=18

so that means that 18 should be added to the data set to get a mean of 13.

Hope this helps!

Answer:

-14

Step-by-step explanation:

Line is passing through the points (5, -8) and (4, 6).

Therefore,

[tex]slope = \frac{ - 8 - 6}{5 - 4} \\ \\ = \frac{ - 14}{1} \\ \\ = - 14[/tex]

Answer:

a) The value of [tex]y[/tex] is 6.

b) This line does not pass through the point of origin.

c) [tex]y = \frac{1}{2}\cdot x + 3[/tex] intersects with [tex]y = -x+32[/tex].

d) Both [tex]y = \frac{1}{2}\cdot x + 3[/tex] and [tex]y = -x+32[/tex] intersect in the first quadrant.

Step-by-step explanation:

a) By Analytical Geometry, we know that an equation of the line can be found by knowing the coordinates of two distinct points on the plane. The equation of the line is defined by this formula:

[tex]y = m\cdot x + b[/tex] (1)

Where:

[tex]x[/tex] - Independient variable.

[tex]y[/tex] - Dependent variable.

[tex]m[/tex] - Slope.

[tex]b[/tex] - x-Intercept.

To determine the slope and x-intercept of the equation of the line, we have to solve the following system of linear equations:

[tex]m\cdot x_{1}+b = y_{1}[/tex] (2)

[tex]m\cdot x_{2}+b = y_{2}[/tex] (3)

If we know that [tex](x_{1}, y_{1} ) = (2,4)[/tex] and [tex](x_{2}, y_{2}) = (-2, 2)[/tex], then the solution of the system is:

[tex]m = \frac{1}{2}[/tex], [tex]b = 3[/tex]

Then, the equation of the line is [tex]y = \frac{1}{2}\cdot x + 3[/tex]. If we know that [tex]x = 6[/tex], then the value of [tex]y[/tex] is:

[tex]y = 6[/tex]

The value of [tex]y[/tex] is 6.

b) If this line passes through the point of origin, then the value of [tex]y[/tex] must be zero for [tex]x = 0[/tex]. If we know that  [tex]y = \frac{1}{2}\cdot x + 3[/tex] and [tex]x = 0[/tex], then the value of [tex]y[/tex] is:

[tex]y = 3[/tex]

The line does not pass through the point of origin since x-intercept is not zero.

c) A system of two linear equations always has an unique solution if and only if slopes and x-intercepts are different to each other. This condition is satisfied by [tex]y = -x+32[/tex], so we conclude that both lines intersect each other.

d) (Note: Question was incorrectly written. Correct form is: If your answer was yes in c, in which quadrant did they intersect?)

First, we solve the following system of linear equations:

[tex]\frac{1}{2}\cdot x -y = -3[/tex] (4)

[tex]-x-y = -32[/tex] (5)

The solution of this system is [tex](x,y) = (19.333, 12,667)[/tex], which means that both lines intersects each other in the first quadrant.

Answer:

La²+8La+16 = La²+70

Step-by-step explanation:

8La+16 = 70

8La=70-16

La=54/8

La= 6.75

Area b = (6.75+4)*(6.75+4)

Area b = 10.75*10.75

Area b =115.563

The area of a square is the square of its side lengths

The area of square B is 116 centimeter square

Let the side length of square A be (a), and the side length of square B be (b)

So, we have:

[tex]\mathbf{A_a = a^2}[/tex]

[tex]\mathbf{A_b = b^2}[/tex]

From the question, we have:

[tex]\mathbf{A_b = 70 + a^2}[/tex]

[tex]\mathbf{b = 4 + a}[/tex]

Take square of both sides

[tex]\mathbf{b^2 = (4 + a)^2}[/tex]

[tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex]

Substitute [tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex] in [tex]\mathbf{A_b = b^2}[/tex]

[tex]\mathbf{A_b = 16 + 8a+ a^2}[/tex]

So, we have:

[tex]\mathbf{16 + 8a+ a^2 = 70 + a^2}[/tex]

Subtract a^2 from both sides

[tex]\mathbf{16 + 8a = 70}\\[/tex]

Subtract 16 from both sides

[tex]\mathbf{8a = 54}[/tex]

Divide both sides by 8

[tex]\mathbf{a = 6.75}[/tex]

Recall that:

[tex]\mathbf{A_b = 70 + a^2}[/tex]

So, we have:

[tex]\mathbf{A_b = 70 + 6.75^2}[/tex]

[tex]\mathbf{A_b = 115.5625}[/tex]

Approximate

[tex]\mathbf{A_b = 116}[/tex]

Hence, the area of square B is 116 centimeter square

Answer:

Slope is equal to the change in y over the change in x , or rise over run.

m=change in y/ change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change  in y is equal to the difference in y-coordinates (also called rise).

m=y2−y1/x2−x1

Substitute in the values of x and y into the equation to find the slope.

m=0−(2)/9−(5)

Simplify.

Answer:

Yes, They are similar by SSS PMK similar to LMQ.

Step-by-step explanation:

Similar triangles corresponding side lengths are in a proportion.

KM corresponds with MQ

PM corresponds with LM.

Set up this proportion.

[tex] \frac{km}{pm} = \frac{lm}{mq} [/tex]
