The image of the transformation of the ordered pair is (-2,-6)

<h3>How to determine the image?</h3>

The ordered pair is given as:

(1, -3)

The transformation is given as:

D₂ o Ry-axis

This means a dilation by a scale factor of 2 and then a reflection across the y-axis.

The image of the dilation is:

(x,y) = 2 * (1,-3)

(x,y) = (2,-6)

The rule of reflection across the y-axis is

(x,y) = (-x,y)

So, we have:

(x,y) = (-2,-6)

Hence, the image of the transformation is (-2,-6)

Find the points at which the graph of the equation -4y=15-5x crossed the x- axis and the y - axis.

Lynna [10]

Answer:

see explanation

Step-by-step explanation:

Where the graph crosses the x- axis the y- coordinate is zero.

Let y = 0 in the equation and solve for x

- 4(0) = 15 - 5x, that is

15 - 5x = 0 ( subtract 15 from both sides )

- 5x = - 15 ( divide both sides by - 5 )

x = 3 ← x- intercept ⇒ (3, 0 )

Where the graph crosses the y- axis the x- coordinate is zero.

Let x = 0 in the equation and solve for y

- 4y = 15 - 5(0), that is

- 4y = 15 ( divide both sides by - 4 )

y = - $\frac{15}{4}$ ← y- intercept ⇒ (0, - $\frac{15}{4}$ )

Answer: point estimate = 0.67 and Margin of error = 0.03 .

Step-by-step explanation:

For confidence interval,

Lower limit = point estimate - margin of error

Upper limit = point estimate + margin of error

Given confidence interval: (0.64, 0.70)

i.e. Lower limit = 0.64

Upper limit = 0.70

i.e. point estimate - margin of error= 0.64 (i)

point estimate + margin of error= 0.70 (ii)

Adding (i) and (ii) , we get

2( point estimate) = 1.34

⇒ point estimate = 0.67

Eliminate (i) from (ii) , we get

2( Margin of error ) = 0.06

⇒ Margin of error = 0.03

Hence, point estimate = 0.67 and Margin of error = 0.03 .
