Step-by-step explanation:

When a dilation in the coordinate plane has the origin as the center of dilation, you can find points on the dilated image by multiplying the x- and y-coordinates of the original figure by the scale factor (here 1.5).

e.g. M (1, 1)

M' should be then (1.5, 1.5).

that eliminates the first and the third answer options.

e.g. J (1, 4)

J' should be then (1.5, 6)

do the second answer option is correct.

Find the value of x

zloy xaker [14]

Answer:

Step-by-step explanation:

EHG is a straight line so it is 180°.

You already know the value of FHG, so you can find the value of 2x.

180° = 48° + 2x

2x = 180° - 48°

= 132

x = 132° ÷ 2

= 66

Answer:

An equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

$y=-6x+7$

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where m is the slope and b is the y-intercept

Given the equation

$6x+y=6$

Writing in the slope-intercept form of the line equation

$y = -6x + 6$

comparing with the slope-intercept form of the line equation

y = mx+b

Thus, the slope of line = m = -6

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line is also -6.

As the line passes through the point (2,−5).

Thus, using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

where m is the slope and (x₁, x₂) is the point

substituting the values m = -6 and the point (2,−5)

$y-y_1=m\left(x-x_1\right)$

$y - (-5) = -6 (x - 2)$

$y+5=-6\left(x-2\right)$

subtract 5 from both sides

$y+5-5=-6\left(x-2\right)-5$

$y=-6x+7$

Therefore, an equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

$y=-6x+7$

Find the percent of increase or decrease?<br> N to 4/5n?

d1i1m1o1n [39]

Answer:

Decrease by 20%.

Step-by-step explanation:

We have to find the percent of increase or decrease from n to $\frac{4}{5}n$ .

Now, $\frac{4}{5}n = 0.8n < n$

So there is a decrease fro n to $\frac{4}{5}n$ .

Now, the percentage of decrease will be given by

= $[ \frac{\textrm {Original Value - Final Value}}{\textrm {Original Value}}]\times 100 \%$

= $[ \frac{n - 0.8n}{n}]\times 100 \%$

= 20% (Answer)
