If y = 2x - 3 , what is the value of x
when y = 1?
A-1
B 1
© - 2
D 2

D. 2

Step-by-step explanation:

We know that y=2x-3. We want to find out what the value of x is when y=1. Therefore, we can substitute 1 in for y in the equation.

Equation: y=2x-3

Substitute 1 in for y: 1=2x-3

Now, solve for x.

1=2x-3

3 is being subtracted from 2x. The inverse of subtraction is addition. Add 2 to both sides.

1+3=2x-3+3

1+3=2x

4=2x

x is being multiplied by 2. The inverse of multiplication is division. Divide both sides by 2.

4/2=2x/2

4/2=x

2=x

The correct answer is D. 2

answer: your correct answer is b. d.

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
