Answer:
9
Step-by-step explanation:
3-sqrt(x)=0 should be rewritten as 3 = sqrt(x) or sqrt(x) = 3.
To obtain the value of x that satisfies this equation, square both sides:
x = 3^2, or x = 9.
Answer:
Step-by-step explanation:
A. S=strawberry, C=chocolate
S+C=14 equation 1
2s+3c=30 equation 2
B. -2(s+c)=-2(14) multiply equation 1 by -2 to use elimination method
-2s+-2c=-28 modified Equation 1
2s+ 3c=30. Equation 2
C=2 add above two equations.
solve for s
s+c=14
s+2=14
s=12
Used elimination method since it was easier to add the two equations.
check answer by inputting s,c values in either equation.
2s+3c=30
2(12)+3(2)=30
24+6=30
30=30
A coefficient goes before a variable and is a constant. When the coefficients are equal but opposite it means you have an even function.
