Y+5=-4(x-3) in standard form

dmitriy555 [2]

Answer:

y + 4x = 7

Step-by-step explanation:

Standard form is the form Ax + By = C. To get this lets put x and y on the same side alone.

y + 5 = -4(x - 3)

y + 5 = -4x + 12

y + 4x = 12 - 5

y + 4x = 7

What are the steps to understanding this problem as well as the answers.

svetlana [45]

Step-by-step explanation:

1

$\frac{1}{3 + 4i} \times \frac{3 - 4i}{3 - 4i} = \frac{3 - 4i}{25} = \frac{ 3}{25} - \frac{4i}{25}$

2)

$\frac{1}{3 - 4i} \times \frac{3 + 4i}{3 + 4i} = \frac{3 + 4i}{25} = \frac{ 3}{25} + \frac{4i}{25}$

3)

1+0i

4)

$\frac{3 - 4i}{3 + 4i} \times \frac{3 - 4i}{3 - 4i} = \frac{ - 7 - 24i}{25} = - \frac{7}{25} - \frac{24i}{25}$

5)

3 - 4i

6)

$\frac{3 + 4i}{3 - 4i} \times \frac{3 + 4i}{3 + 4i} = \frac{ - 7 + 24i}{25} = - \frac{7}{25} + \frac{24i}{25}$

Find sin θ if cot θ = - 2 and cos θ < 0

Masteriza [31]

Given was cotθ=−21 and cot is the reciprocal of tan
therefore
tanθ=1−2
solve for the hypotenuse c since t he opposite side a=1 and the adjacent sides b=−2 were already given. that is,
c2=a2+b2
c=√(1)2+(−2)2
c=√5

Solving for sinθ

sinθ=oppositesideshypoteνse=ab

sinθ=1√5 need to rationalize
sinθ=(1√5)×√5√5

sinθ=√55

Note that the adjacent side of the angle is −2 so the angle
θ is found in the 2nd quadrant.

The 2010 General Social Survey reported a sample where about 48% of US residents thought marijuana should be made legal. If we w

Sati [7]

Answer:

The sample size is $n = 600$

Step-by-step explanation:

From the question we are told that

The sample proportion is $\r p = 0.48$

The margin of error is $MOE = 0.04$

Given that the confidence level is 95% the level of significance is mathematically represented as

$\alpha = 100 - 95$

$\alpha = 5 \%$

$\alpha = 0.05$

Next we obtain the critical value of $\frac{\alpha }{2}$ from the normal distribution table , the values is

$Z_{\frac{\alpha }{2} } = 1.96$

The reason we are obtaining critical value of $\frac{\alpha }{2}$ instead of $\alpha$ is because

$\alpha$ represents the area under the normal curve where the confidence level interval ( $1-\alpha$ ) did not cover which include both the left and right tail while
