Answer:

x = 5

Step-by-step explanation:

For the parallelogram to be a square we use the property

The diagonals of a square are congruent, hence

12x - 23 = 4x + 17 ( subtract 4x from both sides )

8x - 23 = 17 ( add 23 to both sides )

8x = 40 ( divide both sides by 8 )

x = 5

Is the relationship shown by the data linear? If so, model the data with an equation.

Marina CMI [18]

Answer:

4th option

Step-by-step explanation:

The relationship is linear,

putting the value of x in the right side of the equation of option 4, you'll get the value of the left side

putting, x=1

y+4=-1/2(x-1)

y=-1/2(1-1)-4

y=-4

putting, x=7

y+4=-1/2(7-1)

y=-1/2(6)-4

y=-6/2-4

y=-3-4

y=-7

elena55 [62]

Answer:

x = ± $\sqrt{y-7}$

Step-by-step explanation:

Given

y = x² + 7 ( subtract 7 from both sides )

y - 7 = x² ( take the square root of both sides, thus

x = ± $\sqrt{y-7}$
