Answer:
See the attached for a graph.
Step-by-step explanation:
The edge of the solution space is marked by the line ...
... y = 4 - 2x
This is in slope-intercept form. It has a y-intercept of 4 and a slope of -2. Because the relation symbol is "less than" (with no "or equal to"), the line itself is not part of the solution space. It is graphed as a dashed line for that reason.
The values of y in the solution space are those <em>less than</em> the ones that make up the line, so the shading is of the half-plane <em>below</em> the line.
Answer:
SHEEEESSSHHHH
Step-by-step explanation:
that looks hard
First you want to combine like terms. on the first equation we can combine 2x+x=3x. So now we have 3x-3. On the right side we can combine 12+1 so we now have -x+13. Now we will take add an x to -x so it's 0 but we have to do it to the other side as well so now we have 4x-3=13. now we will add three to -3 to make it 0 but again we have to do it to the other side. Now we have 4x=16. We want to figure out what x is so we now divide 4x by 4 so we are just left with x but we need to do it to the other side so your answer is x=4
Answer:
yes
Step-by-step explanation:
12 + 3t = 72
Let t = 20
12 + 3*20 = 72
12 + 60 = 72
72 = 72
This is a true statement so t =20 is a solution
