X=2
Y=-4
2x - 4y=0
Y=-4
2x-4(-4)
2x+16=0
2x=-16
X=-8
Hope it helps.. Not sure whether it is correct.

(2,-4)(0,-4)...notice how the y's are the same...they are both -4. When the y's are the same, this means it is a horizontal line and a horizontal line is represented by y = a number. So ur equation for this line is : y = -4. No matter what x is, y will always be -4.

Answer:

Step-by-step explanation:

The key and the most critical step is to draw the line first. Don't do anything else before that.

(2,-8) (-2,-8)

What you find out is that the y value is always - 8.

So the line has no slope and any x value

y = 0*x + b

y = - 8 is the equation of the line.

Answer:

The calculated value t = 2.038< 2.145 at 0.05 level of significance

Null hypothesis is accepted

There is the average rate is less than μ ≤ 4

Step-by-step explanation:

Step(i):-

The Population of the mean 'μ' =4

sample size 'n' = 16

sample mean 'x⁻' = 4.53

given sample standard deviation 's' = 1.04

level of significance α = 0.05

Step(ii):-

Null hypothesis:H₀ : There is no significance difference between two means

Alternative hypothesis : H₁: There is significance difference between two means

Test statistic

$t = \frac{x^{-} - mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{4.53-4}{\frac{1.04}{\sqrt{16} } }$

t = 2.038

Degrees of freedom ν = n-1 = 16-1 =15

t₀.₀₂₅ = 2.145

Conclusion:-

The calculated value t = 2.038< 2.145 at 0.05 level of significance

Null hypothesis is accepted

There is the average rate is less than μ ≤ 4

The original point is (-3, -1), what is the new point after a translation of 3 units left and 4 units up?

Zielflug [23.3K]

Answer:

New point is ( - 6, 3).

Step-by-step explanation:

x= -3, after translation 3 units left, we get X = - 3 - 3 = - 6

y = -1, after translation 4 units up, we get X = -1 + 4 = 3

New point is ( - 6, 3).
