write an equation that represents the relationship between

Answer:

Answer: k=8

Step-by-step explanation: So your equation is 7+k/4=9. Remember, the goal of this problem is to isolate the k. The first thing you should do is subtract 7 from both sides. You should get k/4=2. Then, multiply both sides by 4 to isolate the k. You should get k=8. Hope this helps!

Answer: B is the correct answer

Answer:

[tex]x > 2[/tex]

Step-by-step explanation:

[tex]–1 > –2(x – 4) – 5(4x – 7)[/tex]

[tex]–1 > –2x + 8 –20x + 35[/tex]

[tex]–1 > - 22x + 43[/tex]

[tex] - 1 - 43 > - 22x[/tex]

[tex] - 44 > - 22x[/tex]

[tex] \frac{ - 44}{ - 22} < \frac{ - 22x}{ - 22} [/tex]

[tex]2 < x[/tex]

[tex]x > 2[/tex]

Answer:

x=5 and n=36

Step-by-step explanation:

For the first question: 32/8 = 4/1

4/1 = 20/x

4x = 20

x = 5

For the second question: 63/81 = 21/27

21/27 = 28/x

21x = 756

x = 36

Answer:

<1=55°

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

Answer:

x = 53

Step-by-step explanation:

The entire line is BC, the line DE bisects the line BC, meaning it cut the line in half. So CE is half of BC, so the equation for CE has to be multiplied by 2. Therefore:

5x - 3 = (2x + 25)2

multiply

5x - 3 = 4x + 50

ad 3 to both sides

5x = 4x + 53

subtract 4x from both sides

x = 53

Input into the equation to check:

5x - 3 = (2x + 25)2

5(53) - 3 = (2(53) + 25)2

265 - 3 = (106 + 25)2

262 = (131)2

262 = 262, it's correct :)

Answer:

Step-by-step explanation:

Given:

Center of hyperbola is at (h,k).

To find:

The standard forms of a hyperbola.

Solution:

We know that, standard forms of a hyperbola are

1. For Horizontal hyperbola:

[tex]\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1[/tex]

2. For Vertical hyperbola:

[tex]\dfrac{(y-k)^2}{a^2}-\dfrac{(x-h)^2}{b^2}=1[/tex]

where, (h,k) is center of the hyperbola.

Therefore, the correct option is B.

Answer:

A. -5(x + 2) = -4x - 12 - x + 2

Step-by-step explanation:

The equation that has infinitely many solutions will be the same on both sides.

A is the correct answer.

Simplify the equation by distributing -5 and adding like terms:

-5(x + 2) = -4x - 12 - x + 2

-5x - 10 = -4x - 12 - x + 2

-5x - 10 = -5x - 10

So, this equation is the same on both sides and will have infinitely many solutions.

A is the correct answer.

Answer:

A has infinitely many solutions

Step-by-step explanation:

Once you distribute A you get

-5x-10= -4x-12-x+2

Once you simplfy all that you get

-5x-10= -5x-10

You can check this by putting in a random number and both sides will be equal.

Answer:

57°

Step-by-step explanation:

[tex] \theta = {sin}^{ - 1} \bigg( \frac{36}{43} \bigg) \\ \\ \theta = 56.846591584 \degree\\ \\ \theta \approx 57 \degree\\ \\ [/tex]

Solution :

Here, [tex]$ \hat p$[/tex] = sample proportion of red outcomes

[tex]$ \hat p =\frac{58}{100}$[/tex]

[tex]$ \hat p$[/tex] = 0.58

So we have to test,

[tex]$H_0 : p = 0.5$[/tex]

V/S    [tex]$H_a: p \neq 0.5 $[/tex]

The test statistic is

[tex]$z = \frac{\hat p - p}{\sqrt{\frac{p(1-p)}{n}}}$[/tex]

[tex]$z = \frac{0.58 - 0.5}{\sqrt{\frac{0.5(1-0.5)}{100}}}$[/tex]

  [tex]$=\frac{0.08}{0.05}$[/tex]

  = 1.600

P value using the z table is 0.110

So P value greater than 0.05

Therefore, there is no evidence that roulette wheel is out of balance.

Answer:

y=1/3x

When x of the line is -3, y of the line must be -1.When x of the line is 6, y of the line must be 2. y=1/3x+b. b is what we want, the 1/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the two points (-3,-1) and (6,2).(-3,-1). y=mx+b or -1=1/3 × -3+b, or solving for b: b=-1-(1/3)(-3). b=0.b came out to be zero, so there is no "+b" term.

Answer:

 Triangle A prime B prime C prime. is obtained by dilating Triangle ABC. by a scale factor of 1 over 2. and then rotating it about the origin by 180 degrees

hope it helps!

Step-by-step explanation:

Triangle ABC is similar to triangle A'B'C' because Triangle A'B'C' is obtained by dilating Triangle ABC by a scale factor of 1 over 3 and then rotating it about the origin by 180 degrees.

m=3

4m-1=4*3-1

so then it's 12-1 which is 11

5m-4=5*3-4

15-4 thats 11

wait ok so

11=11

Answer:

Step-by-step explanation:

m = 3

4m - 1 = 4(3) - 1 = 12 - 1 = 11

5m - 4 = 5(3) - 4 = 15 - 4 = 11

4m - 1 = 5m - 4

Ms Patel bought 4 pliers, 2 wrenches and 1 plier set.

        4:2:1

        PLIERS: 4 × 17.50 = $70

        WRENCHES: 2 × 21.50 = $43

        CHISEL SETS: 1 x 28 = $28

        TOTAL = $70 + $43 + $28 = $141

Mrs Patel purchased 2 wrenches, 4 pliers, and 1 chisel set for her shop.

I hoped this helped!

Step-by-step explanation:

So if there are 3 sizes, 2 flavors and 2 Toppings to choose from, then there are

3 * 2 * 2 possible combinations

For example:

S = 3 sizes

F = 2 flavours

T = 2 toppings

Then there are 3 * 2 * 2 = 12 possible combinations
