Answer: y=(10/9)x+19

Step-by-step explanation:

The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We are given the slope, m:

y=(10/9)x+b

To find b, enter the given point (0,19) and solve for b:

y=(10/9)x+b

19=(10/9)*(0)+b

b = 19

So we have y=(10/9)x+19

Step-by-step explanation:

Answer:

y = x + 1

Step-by-step explanation:

The gradient of a line can be defined by the equation:

m (gradient) = (y1 – y2 ) ÷ (x1 – x2) ----> "1" and "2" should be in subscript

For (-7,-6) we use x2 and y2 (because this point can be anywhere along a line):

x2 = -7, y2 = -6

Plug these values into the formula above:

m = (y-(-6)) ÷ (x-(-7))

m = (y+6) ÷ (x+7)

At this stage, the equation can't be solved as there are two unknowns. Therefore, the gradient must be found another way. Two lines are parallel if they have the same gradient - in their y=mx+c equations, m will be equal.

x - y=7 is the line alluded to in the question. Rearranging this equation into the line equation format gives:

y = x-7 ---> The gradient (coefficient of x) is 1.

Therefore, the gradient of the other parallel line must also be 1.

This can be substituted into the previous equation to give:

1 = (y+6)÷(x+7)

x+7 = y+6

x+1 = y

Therefore, the answer is y=x+1

Answer:

x=-44

x=-44

Answer:

Step-by-step explanation:

Answer:

(2x - 3)(x + 9)

Step-by-step explanation:

A = 2

B = 15

C = -27

when we plug these numbers into the equation  (Ax^2 + Bx + C) we get

2x^2 + 15x - 27

using the "X" method we have to multiply the A term and C term together

so -27 x 2 = -54

so we have to find factors of -54 that also add to the middle term, 15

- 3 and 18 add to 15 but also multiply to -54 so we can add these numbers into the X (refer to drawing)

Answer:

See below

Step-by-step explanation:

The test is one-tailed (left-tailed in this case) because you are trying to prove that the true proportion is less than the proposed proportion of 11%

The test statistic, z, is given to us as z=-1.34 when rounded to 2 decimal places.

The p-value, p, is given to us as p=0.0908 when rounded to 4 decimal places.

The null hypothesis is [tex]H_o:p<0.11[/tex] because the original claim was that the proportion was less than 11%.

Hope this helped! It's been a while since I've done Statistics, but I believe this is all correct.

Recall that for |x| < 1, we have

[tex]\displaystyle \frac1{1-x} = \sum_{k=0}^\infty x^k[/tex]

It follows that, for |-x²| = |x|² < 1, or just |x| < 1,

[tex]\displaystyle \frac1{1+x^2} = \frac1{1-(-x^2)} = \sum_{k=0}^\infty (-x^2)^k = \sum_{k=0}^\infty (-1)^k x^{2k}[/tex]

Taking the antiderivative of both sides gives us

[tex]\displaystyle \arctan(x) = C + \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]

where C is a constant, which we determine to be 0, since taking x = 0 on both sides makes the series vanish, while arctan(0) = 0 since 0 = tan(0). So

[tex]\displaystyle \arctan(x) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]

Since tan(π/4) = 1, it follows that π/4 = arctan(1), so in the series we replace x = 1, then solve for π :

[tex]\displaystyle \arctan(1) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} 1^{2k+1}[/tex]

[tex]\displaystyle \frac\pi4 = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1}[/tex]

[tex]\displaystyle \pi = \sum_{k=0}^\infty \frac{4(-1)^k}{2k+1}[/tex]

[tex]\pi = 4 - \dfrac43 + \dfrac45 - \dfrac47 +\cdots[/tex]

Answer:B. 17%

A.83%

B.17%

C.20%

D.10%

The unemployment rate in this hypothetical country is equal to 17%.

First of all, we would determine the percentage of people that are employed and then subtract this percentage from the total percentage of 100%.

The table below gives the complete information about the population and employment numbers for a hypothetical country:

Mathematically, employment rate can be calculated by using this formula:

[tex]Employment\;rate = \frac{Employed}{Labor\;force} \times 100\\\\Employment\;rate =\frac{500}{600} \times 100\\\\[/tex]

Employment rate = 83.3 ≈ 83%.

For the unemployment rate, we have:

Unemployment rate = 100 - 83

Unemployment rate = 17%.

Answer:

x=4

Step-by-step explanation:

2(10 -6x)=x -8x

Multiply 2*10 and 2*-6x

20-12x=x-8x

Add 12x

20=x-8x+2x

Combine x and -8x

20=-7x+12x

Combine -7x and 12x

20=5x

Divide 5x/5 and 20/5

4=x

So x=4

The solution to the equation is x = -4.

To solve the equation 2(10 - 6x) = x - 8x, you can follow these steps:

1. Distribute the 2 to the terms inside the parentheses:

  20 - 12x = x - 8x

2. Simplify the expressions on each side by combining like terms:

  20 - 12x = -7x

3. Move all the x terms to one side and the constant terms to the other side by adding or subtracting:

  -12x + 7x = 20

  Simplifying further, we have:

  -5x = 20

4. Divide both sides of the equation by -5 to solve for x:

  x = 20 / -5

  x = -4

Therefore, the solution to the equation is x = -4.

Answer:

x=6

Step-by-step explanation:

I don't know if you are solving for x but x=6

9(8 - x) = 3x

Multiply 9x8 and 9-x

72 - 9x = 3x

Add the 9x

72 = 3x + 9x

Add 3x+9x

72 = 12x

Divide 12x/12 and 72/12

12x/12 = 72/12

x = 6

Answer:

9(8 - x) - 3x

⇛72 - 9x - 3x

⇛72 - 12x

⇛12x = 72

⇛x = 72/12

Therefore, x = 6. Ans.
