Answer:
x=-5/2,0
Step-by-step explanation:
It is solved by first factorizing it
10x²+25x=5x(2x+5)=0
Finding the zeros
5x=0x=0/5=0
2x+5=0
x=-5/2
Therefore x is -5/2 or 0
Answer:
f(x) = |x - 4| + 3
Step-by-step explanation:
Identify (from the graph) the coordinates of the vertex: (4, 3). That +4 tells us that the vertex of the basic function y = |x| has been translated 4 units to the right; that +3 tells us that the vertex has also been translated 3 units up. Consider y = |x-a| + b. Here, b = +3 and a=+4. Thus, the correct function is f(x) = |x - 4| + 3.

A
Step-by-step explanation:
Answer:
Child tickets sold: 97
Step-by-step explanation:
Step 1: Write out system of equations
5.90x + 9.10y = 1282.10
x + y = 175
Step 2: Rewrite 2nd equation
y = 175 - x
Step 3: Substitution
5.90x + 9.10(175 - x) = 1282.10
Step 4: Distribute
5.90x + 1592.5 - 9.10x = 1282.10
Step 5: Combine like terms
-3.2x + 1592.5 = 1282.10
Step 6: Isolate <em>x</em>
-3.2x = -310.4
x = 97
And we have our final answer!
