What is its slope?

Answer: To write a percentage as a decimal, simply divide it by 100. For example, 50% becomes 0.5, 20% becomes 0.2, 1% becomes 0.01 and so on. We can calculate percentages using this knowledge. 50% is the same as a half, so 50% of 10 is 5, because five is half of 10 (10 ÷ 2).

Step-by-step explanation:

Answer:

y = -3x + 3

Step-by-step explanation:

Since the line is parallel, it has the same slope. Plug the point you have into the equation y - y1 = slope (x -x1) to get your answer, which should be y = -3x +3

Hopefully this helps - let me know if you have any questions!

Answer:

C: y = -3x +3

Step-by-step explanation:

Lines that are parallel have the same slope have so the slope of the line in -3, now we have to find the y-intercept, we can do this by substituting -2 for x and 9 for y and solve for b

9 = -3(-2) +b

9 = 6 + b

b = 3

So the line that is parallel to y = -3x -8 and goers through the point (-2,9) is y = -3x + 3 or answer C

Answer:  n = -1

Step-by-step explanation: distribute 7 to n +4 to get 7n +28 = 21

subtract 28 on both sides, to get 7n= -7 divide by positive 7, and get n=-1

plug it in to check 7(-1+4)=21

-1+4= 3

7(3)= 21

it checks out ^_^

Answer:

A. 9

Step-by-step explanation:

So, she has 460 beads, and each braclet she makes requires 50 beads.

Therefore we will divide these numbers to get 9.2. This rounds to A. 9.\

Answer:

16.5

Step-by-step explanation:

(18-7) = 11

11 x 3 = 33

33 divided by 2 = 16.5

Answer:

[tex]16\frac{1}{2}[/tex]

Step-by-step explanation:

[tex]\frac{3 (18 - 7)}{2} =\frac{3*11}{2}=\frac{33}{2}= 16\frac{1}{2}[/tex]

Answer:

28

Step-by-step explanation:

a^2+b^2=c^2

a^2+96^2=100^2

a^2+9216=10000

a^2=784

a^2= √784

a=28

Answer:

Step-by-step explanation:

Let,

The unknown leg be = x

According to Pythagoras Theorem,

[tex] {hypotenuse}^{2} - {base}^{2} = {height}^{2} [/tex]

[tex] = > {100}^{2} - {96}^{2} = {x}^{2} [/tex]

[tex] = > {x}^{2} = 10000 - 9216[/tex]

[tex] = > {x}^{2} = 784[/tex]

[tex] = > x = \sqrt{784} [/tex]

=> x = 28

Hence,

the another leg is 28 in. (Ans)

Step-by-step explanation:

We can just follow what it says.

16 times 3 times 29 = 1392

1392 - 17 = 1375

Answer:

-3/19

Step-by-step explanation:

Given data

We have the coordinates

(12, 2), (-7,5)

x1=12

y1=2

x2=-7

y2=5

The expression for the slope is given as

Slope= y2-y1/x2-x1

Substiute

Slope=  5-2/-7-12

Slope= 3/-19

Hence the slope is -3/19

Answer:

-3<y<=3 or B

Step-by-step explanation:

first we find the smallest y value which is -3

then we find the largest y vlaue which is three

so since there is an open circle at negative three we do not include it while at three we do.

so the answer would be -3<x<=3

Answer: 4= 2 8=3 12=4

Step-by-step explanation:

We see that 1/4 is the x, so we can multiply 4 by 1/4 which gives us 1 and then we add 1 because the equation has a +1. Now we do the same to the 8, 8(1/4 +1) =3.

Answer:

[tex]x=-4+\sqrt{2}[/tex]

[tex]x=-4-\sqrt{2}[/tex]

Step-by-step explanation:

The quadratic formula is an equation that can be used to find the roots of a quadratic equation when one is given the equation in standard form. A quadratic equation in standard form is the following,

[tex]ax^2 +bx + c=0[/tex]

The quadratic formula is the following,

[tex]\frac{(-a)(+-)\sqrt{(x)^2-4(b)(c)}}{2(a)}[/tex]

Substitute in the given coefficients for the following equation,

[tex]2x^2 + 16x + 28 = 0[/tex]

Substitute,

[tex]\frac{-16(+-)\sqrt{(16)^2-4(2)(8)}}{2(2)}[/tex]

Simplify,

[tex]\frac{-16(+-)\sqrt{256-224}}{4}\\\\=\frac{-16(+-)\sqrt{32}}{4}\\\\=\frac{-16(+-)4\sqrt{2}}{4}\\\\=-4(+-)\sqrt{2}[/tex]

The roots of the quadratic equation ([tex]2x^2+16x+28=0[/tex]) are  ([tex]x=-4+\sqrt2[/tex]) and ([tex]x=-4-\sqrt{2}[/tex])

Answer:

(5.240 ; 8.760)

Step-by-step explanation:

Given :

Sample mean, xbar = 7

Standard deviation, s = 2.29

Sample size, n = 9

95% confidence interval for the population mean :

Confidence interval :

Xbar ± Margin of error

Margin of Error = Tcritical * s/sqrt(n)

Tcritical at 0.05 ; df = 8 = 2.306

Margin of Error = 2.306 * 2.29/sqrt(9)

Margin of Error = 1.760

Lower boundary = (7 - 1.760) = 5.240

Upper boundary = (7 + 1.760) = 8.760

(5.240 ; 8.760)
