Ths question is not complete but I will try my best to guide you through it so you can answer it. So what the question is asking you to do is that you have to plug in the coordinates into the equation. I don't want to give you an incorrect answer so I will explain it and you can do it yourself with the full question. First use the second equation as it is a full equation with an equal sign. Once plugged in you can find that c and d do not make the second equation true. A and B both complete the second equation. This means that either A or B is the answer. Since the first equation does not have an equal sign meaning it is not complete I can not answer it and I am sorry. But I have cut the answer down for you to A and B. If this answer helped you in the slightest please check out my channel The Game Rater. Thank you and I appreciate it.

Answer:

y-intercept is (0, -2) and asymptote of y = -2.5

Step-by-step explanation:

If you substitute 0 in for x and simplify, then you will have the y-intercept

y = [tex]\frac{1}{2} (7)^{0} - 2.5 = \frac{1}{2} (1) - 2.5 = \frac{1}{2} - 2.5 = -2[/tex]

The y-intercept is (0, -2)

If the -2.5 were not there, then the graph would have an asymptote at y = 0 or the x-axis

The -2.5 moves the graph down 2.5 units so that y = -2.5 is the asymptote

Therefore, the first answer is correct

Answer:

x = 25

y = 65

Step-by-step explanation:

(I did it on Math Nation)

180 = 130 + 2x

50 = 2x

x = 25

180 = 50 + 2y

130 = 2y

y = 65

The polar form of z is:

Explanation:

z = −2 + 4i

z = 4.4721 · (cos 117o + i · sin 117o)

The polar form of the complex number z = a + bi is:

z = r · (cos θ + i · sin θ)

where, r is the modulus of z and θ is an argument of z. The moduo for a = −2 and b = 4 is:

r = a2 + b2 = · · · = 4.4721 To find argument θ we use one of the following formulas:

b θ=arctan a ifa>0

b o θ=arctan a +180 ifa<0

θ=90o ifa=0andb>0 θ=270o ifa=0andb<0

Inthisexample: a=−2andb=4so:

θ=arctan a +180

θ=arctan 4 +180o −2

b o

θ = arctan (−2) + 180o θ ≈ 117o

Answer:

Step-by-step explanation:

a+bi = -2+4i

arctan(b/a)=arctan(4/-2)=-1.071

Because this falls in quardant 2, you have to add pi

1.071+pi=2.03

The solution of the given inequality is required.

The required graph is attached.

The given inequality is [tex]x+1>3[/tex]

Solving the inequality  we get

[tex]x+1>3\\\Rightarrow x>3-1\\\Rightarrow x>2[/tex]

The points which are greater than 2 all will be the solution set of the inequality.

The solution set will be [tex](2,\infty)[/tex]

In the graph the points towards the right of x = 2 will be in the solution set.

The point x = 2 will not be in the solution set.

Answer:

x = - 1, x = - 11

Step-by-step explanation:

Given

2| x + 6 | - 4 = 6 ( add 4 to both sides )

2|x + 6 | = 10 ( divide both sides by 2 )

| x + 6 | = 5

The absolute value function always gives a positive result, but the expression inside can be positive or negative, that is

x + 6 = 5 or - (x + 6) = 5

solve both

x + 6 = 5 ( subtract 6 from both sides )

x = - 1

or

- (x + 6) = 5 , that is

- x - 6 = 5 ( add 6 to both sides )

- x = 11 ( multiply both sides by - 1 )

x = - 11

Answer:

11, 8

Step-by-step explanation:

x + y = 17

x - y = 5

The "y" cancels out when you add the two equations and you end up with:

2x = 22

x = 11

Then, plug the "x" back into one of the equations to find "y":

11 + y = 17

y = 6

Answer:

x = 2

Step-by-step explanation:

[tex]2log_5 x = log_5 4 \\ \\ log_5 {x}^{2} = log_5 4 \\ \\ \implies \: {x}^{2} = 4 \\ \\ \implies \: x = \pm \sqrt{4} \\ \\ \implies \: x = \pm 2 \\ \\ x = - 2, \: \: x = 2[/tex]

Since, anti-logarithm must be greater than zero.

[tex] \therefore x\neq - 2[/tex]
