Answer: B

Step-by-step explanation: I took the quiz and got it right

Also, if you graph the equations on a graphing calculator, the lines are right on top of each other, so the first equation can't be less than -1, so no solutions

C=.41+.26(z-1) solve for z

Ksivusya [100]

$c=0.41+0.26(z-1) \\0.26(z-1)=c-0.41 \\z-1=(c-0.41)/0.26 \\\boxed{z=(c-0.41)/0.26+1}$

Hope this helps.

Which of the following equations is equivalent to y + 3 = -4(x - 2)?

Allushta [10]

Answer:

D. y= -4x +5

Step-by-step explanation:

The equation $y+3=-4(x-2)$ can be transformed by doing some algebra.
If we solve the second term of the equation -4(x-2)= 8 - 4x, then we have $y+3=8-4x$ (this is done by distributing the multiplication into the two terms: remember that the product of -4x(-2)=+8 because the product of two negative numbers is a possitive number).
Then, by subtracting both sides 3, we have $y=5-4x$ . Rearranging terms in the right side, we have $y=-4x+5$ , which is option D.
