Let n be the number. The difference of the number and six is n-6. Then three times the difference of the number and six is 3·(n-6). This number 3·(n-6) increased by four times the number n, then
3·(n-6)=4·n.
Solve it:
3·n-3·6=4n,
3n-4n=18,
-n=18,
n=-18.
Answer: n=-18 and expression is 3·(n-6)=4·n.

Answer:
-5
Step-by-step explanation:
The square of x is written x^2. Thus, we have x^2 + 10x + 26 here. Using the axis of symmetry formula x = -b/(2a), we get:
-10
----- = -5
2(1)
Answer:
slope = 
Step-by-step explanation:
Find the slope of the line using the slope formula, 
. The formula requires two points from the line - and looking at the graph, (1, 10) and (6, 9) are two points the line passes through (but any other points the line also passes through would work fine, too). So, substitute the points' x and y values into the formula and solve:
Therefore, 
is the slope.
