Answer: Given that Li is making beaded necklaces for each necklace, she uses 27 spacers, plus 5 beads per inch of necklace length.

The equation to find how many beads Li needs for each necklace can be obtained as follows:

A. The input variable is the number of inches of the necklace length (x).

B. The output variable is the number of beads Li needs for each necklace (y).

C. The required equation is given by

y = 5x

Answer:

d) XY > RS

Step-by-step explanation:

When comparing triangles, the angle opposite to the side in question determines the length. In this case 99 is greater than 75. Since XY is the side opposite to 99, it is the larger side

Answer:

x²+y²=13

Step-by-step explanation:

x+y=5

now,

squaring both side

(x+y)²=5²

x²+2.x.y+y²=25

x²+y²+2×6=25 (putting value of xy=6)

x²+y²=25-12

x²+y²=13

Answer:

8/17 and 9/17

Step-by-step explanation:

8:9

both add up to 17

so it can be 8/17 or 9 but it cannot be simplified unless if you want them both as a mixed number which is

8/17 as a mixed number is 2 1/17

9/17 as a mixed number is 1 8/17

Answer:

$1473

Step-by-step explanation:

cost of cloth= rs.950

He spent rs.150  for stitching a shirt

total cots= 950+150

total cost=1100

gain= rs.375

we know that

gain= selling price- cost price

substitute

375= selling price- 1100

selling price= 1100+373

selling price=$1473

Hence the selling price is $1473

Answer:

y- intercept = - 2.5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)

m = [tex]\frac{-25+7}{5-1}[/tex] = [tex]\frac{-18}{4}[/tex] = - 4.5 , then

y = - 4.5x + c

To find c substitute either of the 2 points into the equation

Using (1, - 7), then

- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5

y- intercept c = - 2.5

Answer:

width= 15

length=25

Step-by-step explanation:

width= x

length= 10+x

2(10+x+x)= 80

2(10+2x)= 80

20+4x= 80

4x=60

x= 15

width= x= 15

length= 10 +x= 10+15= 25

Answer:

-5 or (-5,0)

Step-by-step explanation:

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

The solution is : the equation of the axis of symmetry is  x= -5 or (-5,0).

The parabola is a plane curve which is mirror symmetrical and is approximately U-shaped. It fits several superficial different mathematical descriptions.

here, we have,

we know that,

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves.

The axis of symmetry always passes through the vertex of the parabola .

The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Hence, The solution is : the equation of the axis of symmetry is  x= -5 or (-5,0).

The nth term of the given sequence

[tex]a_{n} = a_{n-1} + (2n-1)[/tex]

Step-by-step explanation:

Explanation:-

Given sequence  -5,-4,-1,4,11,20,31

a₀ = -5

a₁ = a₀ +1 = -5 +1   = -4

a₂ = a₁ + 3 = -4+3  = -1

a₃ = a₂ + 5 = -1 +5 = 4

a₄ = a₃ + 7 = 4 + 7  =11

a₅ = a₄ + 9 = 11+9 = 20

a₆ = a₅ + 11 =  20+11 = 31

a₇ = a₆ + 13 = 31 +13 =44

and so on

The nth term of the given sequence

Answer:

There is no x-intercept, only a y-intercept, which would be 1

Step-by-step explanation:

The conjugate of the complex root must also be a zero of the function if the complex root is already a zero.

Conjugate of -4 + 3i is -4 - 3i.

Hence -4 - 3i is also a zero of the function.

Answer:

-4 - 3i

Step-by-step explanation:

If a zero of a function is a+bi, there is at least one other zero, a-bi, called the conjugate.

Answer:

We conclude that the slope of the graph of y = 5 x is 5.

Step-by-step explanation:

We know the slope-intercept form of the line equation

y = mx+b

where

Given the line

y = 5x

comparing with the slope-intercept form of the line equation

The slope of the line = m = 5

Therefore, we conclude that the slope of the graph of y = 5 x is 5.

Negative numbers dont have real roots, so you cannot have a square root of -1

Example: -1 x -1 does not equal -1, so this means you cannot do the same the other way

Answer:

Real numbers can be positive or negetive and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers. Imaginary numbers are numbers that cannot be quantified, like the square root of -1.
