Answer:
His new income is $26,910.
Step-by-step explanation:
As Regi has received an increase in his annual salary that has represented $ 910 in his payment, to determine his new salary the following calculation must be performed:
910 / 3.5 = 1% salary
260 = 1% salary
260 x 100 = previous salary
26,000 = previous salary
26,000 + 910 = current salary
26,910 = current salary
Therefore, his new income is $26,910.

Answer:
The system of equations are;
3x + 2y = 170
4x +6y = 360
Step-by-step explanation:
Form simultaneous equations and solve
Let x=price of children tickets
Let y=price of adult tickets
The Brown Family paid $170 for 3 children and 2 adults , this forms the equation as:
3x + 2y =$ 170
3x + 2y = 170 --------------------------equation (i)
The Peckham Family paid $360 for 4 children and 6 adults.
4x + 6y = $360
4x +6y = 360 ---------------------------equation (ii)
Solving the equations by graph will give value of x=30 and y=40
The price of children tickets was $30 and that of adults was $40

Let f(x)=x3(exponent)+kx2(exponent)+x+5
When f(x) is divided by (x+2) the remainder is =3
This is the remainder theorem
so,f(−2)=−8+4k−2+5=3
4k=3+5=8
k=2
