It’s -37 because -20-17=-37
Answer:
option (b) is correct.
The value of 
is 0.
Step-by-step explanation:
Given: 
and 
We have to find the value of
Consider the given function
First evaluate value of function f(x) at x = 3 and 1 then substitute it in .
f(3) = 1 + 3 = 4
f(1) = 1 + 1 = 2
Substitute, we get
Solving further , we get,
Now evaluate at t = 0 , we get,
Thus, value of is 0.
Thus, option (b) is correct.
Answer:
74
Step-by-step explanation:
Part A:
Variable is a symbol for a number we don't know yet. It is usually a letter like x or y but can be any letter.
Example: 6z means 6 times z, and "z" is the variable.
Hence, the variables are c and w. [ Choose any one for your answer ]
Coefficient is any number used to multiply a variable.
<span>Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.
</span>
Hence, the coefficients are 20 and 5. [Choose any one for your answer]
A constant is a<span> fixed value which does not change regardless of the variables entered.
</span>
Hence, the constant is 95.50
Part B:
Weeks saved (w) = 20
Cars washed (c) = 5
20c + 5w + 95.50 = (20 * 5) + (5 * 20) + 95.50 = 100 + 100 + 95.50 = 295.50
Hence, Marla will have $ 295.50 in her account.
Part C:
In <span>20c + 5w + 95.50, Marla's mom deposits $ 20 after every car wash.
If Marla's mom deposits only $ 10 after every car wash, then, the new equation would be : 10</span><span>c + 5w + 95.50
Hence, the coefficient will change from 20 to 10. </span>
