MORE MEDALZ! Solve. |x| + 3 = 7 A. {–10} B. {4} C. {–4, 4} D. {–10, –4}
|x| + 3 = 7 Subtract 3 to both sides, what's 7 - 3?
B. 4 because you subtract 7 from 3.
7-3=4
@r_josh10 Don't give answers, we have to have the asker's participation..plus that's wrong.
@killit!gentlythough. Yes, so our answer is -4 and 4, because the absolute value sign will make -4 positive.
absolute values are always positive, even when they say they are negative
Unless the negative sign is outside of the absolute value sign.
{x} means how far the number is from the number line.
okay thanks you guys!
YW :)
Actually A negativeplus a positive is a ngative
No problem. :)
What does that have to do with this question? @r_josh10
one moar qustin
what
Select the graph that represents the inequality. 2x + 3y < 6
add negative 3 to both side
then divide by both side. and theres your answer
Let's solve for x. 2x+3y<6 Step 1: Add -3y to both sides. 2x+3y+−3y<6+−3y 2x<−3y+6 Step 2: Divide both sides by 2. 2x 2 < −3y+6 2 x< −3 2 y+3 Answer: x< −3 2 y+3
graphs are here:
Theres only on graph.
2x + 3y < 6 temporarily put = in for < 2x + 3y < 6 3y < -2x + 6 y < -2/3x + 2 slope is -2/3 y intercept is (0,2) x intercept can be found by subbing in 0 for y 2x + 3y = 6 2x + 3(0) = 6 2x = 6 x = 3....x intercept is (3,0) so the intercepts are (3,0) and (0,2).....and since it is less then with no equal signs, you use open circles with shading below the line
nvm what I said about temp removing the < sign
line is dashed right?
line is dashed because there is no equal sign..correct
I got it. thank you!
the graph you posted looks correct except it needs a dashed line
