Answer:
f(2) = -2
Step-by-step explanation:
To solve this, you have to plug in 2 for x
f(2) = -2^2 + 2(2) - 10
= 4 + 4 - 10
= 8 - 10
= -2
Step 1
Multiplication property of equality
Multiplying the first equation by 5 and the second equation by 7
Step 2

Adding the two equations you get 31a =217
step 3
Division property of equality
Dividing both sides of the above equation by 31 to get the value of a
step 4
Substitution property of equality
Substituting a with 7 in the first equation
step 5
Simplify
simplifying the equation got above
step 6
Using associative property of addition by taking 14 to the other side of the equation.
step 7
Division property of equality
