What is the value of the function y=2x+3 when x=1? A. 5 B. –5 C. 2 D. 1

OpenStudy (myth1111):

Substitute 1 for x and solve it.

OpenStudy (anonymous):

so its 1 xD @myth1111

OpenStudy (myth1111):

If you sub 1 for x, you get the equation y = 2(1) + 3. Just simplify that.

OpenStudy (anonymous):

x= -1 ..

OpenStudy (anonymous):

y=2*-1+3= 1

OpenStudy (myth1111):

The question you posted has x=1, let me solve this with -1.

OpenStudy (myth1111):

Yes, with -1 the answer is 1.

OpenStudy (anonymous):

oops sorry xD but thanks
