X=0.5
y=1
(4x0.5) + (7x1) = 9
2 + 7 = 9
I don't think there is one. A triangular pyramid has 4 faces and 4 vertices, and a <em>square pyramid</em> has 4 faces and 5 vertices;
Answer:
m=1 b=4
Step-by-step explanation:
slope: y=mx+b m=1
interception: b=4
Answer: Option A. The solution set is (4,5)
Step-by-step explanation:
Solve the equation for<em> </em>y to obtain the form of the equation of the line.
You have:
y=-x+9 (The slope is -1 and the y-intercept is 9)
y=x+1 (The slope is 1 and the y-intercept is 1)
When you graph it you obtain the graph shown in the figure attached.
The solution is the intersection of the lines.
Then, the solution set is (4,5)
