this is the best thing i could find for you, good luck with your question,
5x is greater than or equal to -25
The product of 5 and a number is at least –25
we convert the given statement into inequality
product means multiplication
Let x be the unknown number
product of 5 and a number is 5x
5x is at least -25
For word at most we use <=
for word at least we use >=
So the expression becomes 5x <= -25
Answer:
f(7) = -113
Step-by-step explanation:
Hello!
Substitute 7 for x in the equation.
<h3>Evaluate</h3>
- f(x) = -4x² + 10x + 13
- f(7) = -4(7)² + 10(7) + 13
- f(7) = -4(49) + 70 + 13
- f(7) = -196 + 70 + 13
- f(7) = -113
f(7) is -113.

Answer:
2x+4
Step-by-step explanation:
Given that a is the average (arithmetic mean) of 4x and 7, b is the average of 5x and 6, and c is the average of 3x and 11
By definition of arithmetic mean,
we have 
Let us calculate sum of a,b,c in terms of x
a+b+c = 
Average = sum/3 =
