Answer:
1 solution
Step-by-step explanation:
y = 1/2x + 4
x + 2y = -8
Solve the second equation for y.
2y = -x - 8
y = -1/2x - 4
The two equations in slope-intercept form are:
y = 1/2x + 4
y = -1/2x - 4
The system consists of two lines with different slopes, so they intercept at a single point which is the solution.
Answer: 1 solution
slope=(-16-5)/(-8-18)=21/26
18%==59.04
20%=65.60. $124.65 +$÷328.=$452.64 $452.64
total $124.65
Answer:
i cant load the picture
Step-by-step explanation:
First we have to simplify
3r + 2 < 5
subtract 2 from each side then divide by 3
r < 1
7r - 10 > 60
add ten to both sides. divide by 7.
r > 10
answer: r<1 or r>10
if you have to graph, you should have a number line going from 0 to 11. You should put an open circle on 1 and an open circle on 10. Shade to the left from the open circle on 1, and then shade from the right from the open circle on 10.
Your union should look like this:
(-♾, 1)U(10,+♾)
