-2x - 4 > 10
Multiply both sides by -1 and reverse the inequality symbol.
2x + 4 < -10
Now subtract both sides by 4.
2x + 4 - 4 < -10 - 4
2x < -14
Divide both sides by 2.
2x/2 < -14/2
x < -7
Answer: f(3) = 14
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given function</u>
f(x) = 4x + 2
<u>Substitute value of the x into the expression</u>
f(3) = 4(3) + 2
<u>Simplify by multiplication</u>
f(3) = 12 + 2
<u>Simplify by addition</u>
f(3) =

Answer:
The answer is 23/33 Brainliest if you can
Step-by-step explanation: I did the test and 69/100 was wrong
1/5k+ 15
= 1/5k+ 15* (5/5) (because 5/5= 1)
= 1/5k+ (15*5)/ 5
= 1/5k+ 75/5
= 1/5k+ 75* (1/5)
= 1/5(k+ 75) (distributive property)
The final answer is 1/5(k+ 75).
