X = -1 y = -0.5
7 times -1 = -7.
2 times -0.5 = -1, -1+-7= -8
8y= -4, 4x= -4,
Hope this helps!

A statue that is 80 m tall stands on a 625 m2 base. An artist creates a replica using a ratio of 1:15. What is the area of the r

Sholpan [36]

Answer: $2.78m^{2}$

Step-by-step explanation:

given data:

height of the statue = 80m.

base of the statue = $625m^{2}$ .

scale of the statue replica = 1:15.

solution:

$= 1:15^{2} \\\\\= 1:225\\\\$

$= \frac{625m^{2} }{225}$

= $2.78m^{2}$

the area of the replica is $2.78m^{2}$

Which is equivalent to 4y-2x=16

ad-work [718]

X-intercept. y-intercept
4*0-2x=16. 4y-2*0=16
-2x+0=16. 4y-0=16
-0. -0. +0 +0
-2x. /-2 = 16/-2 4y/4 =16/4
x = -8. y = 4
(-8,0) (0,4)

Mrs. Sloan draws two figures on the board.

Trava [24]

A dilated shape will either be enlarged or compressed.

Allen did not make any mistake, and the scale factor is 3.

The dimension of the smaller rectangle (figure Z) is:

3 units by 4 units

The corresponding dimension of the bigger rectangle (figure Z') is:

9 units by 12 units

The scale factor (k) is calculated by dividing the dimensions of Z' by Z.

So, we have:

$k = \frac{9}{3}$

$k = 3$

$k = \frac{12}{4}$

$k = 3$

Notice that both values of k are the same (i.e. 3)

This means that the scale factor is 3

Also figure Z and Z' share the same center of origin at point X

This means that the center of dilation from Z to Z' is X

Hence,

Allen made no mistake, and she is correct about the scale factor.
