In a park, the locations of a drinking fountain, a streetlight and a flagpole form a right triangle. The drinking fountain is 12 yards north of the streetlight, and the flagpole is 5 yards east of the drinking fountain.
What is the shortest distance, in yards, from the streetlight to the flagpole?

7

11

logv3(x+2)=1
rewrite in exponential form:
logb(x) = y is equal to b^y =x
b = 3, y = 1
now solve for x:
3^1 = x+2)
x = 3-2
x = 1
see the picture for the graph.
x = -3
y = -18
step-by-step explanation:
to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.
x-1/3(3x-9) = -3 since y=3x-9 substittute y.
x-1/3(3x-9)=-3
x + x +3 = -3
2x+3=-3
2x+3-3= -3-3
2x=-6
x=-3
substitute again into y=3x-9
y=3(-3)-9
y=-9-9
y=-18
5x + 5
step-by-step explanation:
you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.
(f + g)x = -x^2 +3x + 5 + x^2 + 2x
(f + g)x = 5x + 5
the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
