C is in Q1 bc Q1 is the one in the top right
Answer:
1.
a burger costs $5
an order of fries costs $3
2.
7 pennies
14 nickels
23 dimes
Step-by-step explanation:
x = price of a burger
y = price of a order of fries
5x + 3y = 34
4x + 4y = 32
=>
x + y = 8
x = 8-y
5×(8-y) + 3y = 34
40 - 5y + 3y = 34
-2y = -6
y = $3
x = 8 - 3 = $5
x = number of pennies
y = number of nickels
z = number of dimes
0.01×x + 0.05×y + 0.1×z = 3.07
y = 2x
x + y + z = 44
x + 2x + z = 44
3x + z = 44
z = 44 - 3x
0.01×x + 0.05×2x + 0.1×z = 3.07
0.11×x + 0.1×z = 3.07
0.11×x + 0.1×(44-3x) = 3.07
11x + 10×(44-3x) = 307
11x + 440 - 30x = 307
-19x = -133
x = 7
y = 2×7 = 14
z = 44 - 3×7 = 44 - 21 = 23
Answer:
When applicable, state the domain restriction. g(f(x)) 4 x2 + 1 16 x2 + 3 4 x2 + 7 16 x2 - 8 x + 3 Please help. I thinks that it is 16 x2 + 3. College Algebra. Consider the function f(x)=4 - x^2 for the domain [ 0,∞). Find f^−1 (x), where f^−1 is the inverse of f
Step-by-step explanation:
A is on top
B is the second one (in the middle)
C is the next one
Then D has the how to do it
The sequence whose <em>first</em> term is - 4 and defined recursively by the formula f(n + 1) = f(n) + 3 have the element - 1 as the <em>next</em> term. (Correct choice: B)
<h3>How to determine an element of a sequence</h3>
In mathematics, sequences are sets whose elements observe at least a condition, which is represented by a <em>recursion</em> formula in this question:
f(n + 1) = f(n) + 3
Thus, the following term of the sequence is:
f(2) = f(1) + 3
f(2) = - 4 + 3
f(2) = - 1
The sequence whose <em>first</em> term is - 4 and defined recursively by the formula f(n + 1) = f(n) + 3 have the element - 1 as the <em>next</em> term. (Correct choice: B)
<h3>Remark</h3>
The statement is poorly formatted and reports typing mistakes. Correct statement is:
<em>A sequence is defined recursively by the formula f(n + 1) = f(n) + 3. The first term of the sequence is - 4. What is the next term in the sequence? </em><em>a)</em><em> - 7, </em><em>b)</em><em> - 1, </em><em>c)</em><em> 1, </em><em>d)</em><em> 7</em>
