Answer:

The coordinates of the image are

W'(2,-4)

X'(3,-6)

Y'(6,0)

Z'(5,-2)

Step-by-step explanation:

we know that

The translation is 8 units right and 3 units down

The rule of the translation is

(x,y) ----> (x+8,y-3)

Apply the rule of the translation to the coordinates of the pre-image WXYZ to obtain the coordinates of the image W'X'Y'Z'

coordinate W'

W(-6, -1) ----> W'(-6+8,-1-3)

W(-6, -1) ----> W'(2,-4)

coordinate X'

X(-5, -3) ----> X'(-5+8,-3-3)

X(-5, -3) ----> X'(3,-6)

coordinate Y'

Y(-2, 3) ----> Y'(-2+8,3-3)

Y(-2, 3) ----> Y'(6,0)

coordinate Z'

Z(-3, 1) ----> Z'(-3+8,1-3)

Z(-3, 1) ----> Z'(5,-2)

therefore

The coordinates of the image are

W'(2,-4)

X'(3,-6)

Y'(6,0)

Z'(5,-2)

10-12 please help, find the missing number and once you found the missing number and answered it you make sure it’s the solution

irinina [24]

10. Infinitely many solutions:

$2(x-1)+6x=4(?-1)+2.$

Simplify this equation:

$2x-2+6x=4\cdot ?-4+2,\\ \\8x-2=4\cdot ? -2,\\ \\8x=4\cdot ?$

When $?=2x,$ the equation becomes

$8x=8x \text{ or } 0=0.$

This equality is true for all x, thus the equation has infinitely many solutions.

11. The equation $5x-(x-2)=2x-(?)$ should have one solution x=-1.

First, simplify the equation:

$5x-x+2=2x-?,\\ \\4x+2=2x-?,\\ \\2x+2=-?,\\ \\?=-2x-2.$

This equation will have solution x=-1 when

$?=-2\cdot (-1)-2=2-2=0.$

Therefore, the initial equation is

$5x-(x-2)=2x.$

12. The equation $-(x-8)+4x=2\cdot ?+x$ should have infinitely many solutions.

Simplify it:

$-x+8+4x=2\cdot ?+x,\\ \\2x+8=2\cdot ?,\\ \\2(x+4)=2\cdot ?.$

When $?=x+4,$ this equation will have infinitely many solutions.

Find $y$ if the point $(-6,y)$ is on the line that passes through $(-1,7)$ and $(3,-2)$.

vichka [17]

Answer:

y = 18.25

Step-by-step explanation:

The 2-point form of the equation of a line can be used to write the equation of the line through the given points.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (-2 -7)/(3 -(-1))(x -(-1)) +7

y = -9/4(x +1) +7

For x = -6 this evaluates to ...

y = -9/4(-6 +1) +7 = (9/4)(5) +7 = 45/4 +7

y = 18 1/4
