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
Answer:
1.7 is what 3^2
Step-by-step explanation:
Answer:
<span>r≤−10∪r≥4</span>
Explanation:
<span><span>|<span>r+3</span>|</span>≥7</span>
SOLUTION 1
<span>r+3≥7</span>
<span>r≥4</span>
SOLUTION 2
<span>r+3≤−7</span>
<span>r≤−10</span>
Since the two inequalities do not intersect when graphed, the solution set is
<span>r≤−10∪r≥<span>4 </span></span>
