Answer:
<h2>there are 22 dimes</h2><h2>there are 44 nickles</h2><h2 />
Step-by-step explanation:
D be dimes and N be nickles
2 nickles as dime
nickle = 5 cents and dime =10 cents
N=2D
0.10 D + 0.05 (N)=4.4 substitute N=2D
0.10 D +0.05(2D)=4.4
0.10D+0.10D=4.4
0.20 D=4.4
D=4.4/0.2 = 22
<h2>there are 22 dimes</h2>
N=2D
N=2(22)
N=44
<h2>there are 44 nickles</h2>
check : 0.10(22)+0.05(44)= 4.4 (correct)

9c
Step-by-step explanation:
8c +c = 9c
Answer:
Step-by-step explanation:
The image on the right is not the answer. It is reflected across the y axis. equations and the inverses are reflections of each other across the line y = x. So that lets out the middle one as well which looks to be reflected across y = - x
That only leaves the left image which is the correct answer.
The degree of a polynomial is the highest exponent or sum of exponents of the variables in the individual terms of a polynomial.
Looking at each the polynomial:
3x5 + 8x4y2 – 9x3y3 – 6y5: Degree is 6 (look at the 2nd and 3rd term)
2xy4 + 4x2y3 – 6x3y2 – 7x4: Degree is 5 (look at 1st, 2nd, and 3rd term)
8y6 + y5 – 5xy3 + 7x2y2 – x3y – 6x4: Degree is 6 (look at 1st term)
–6xy5 + 5x2y3 – x3y2 + 2x2y3 – 3xy5: Degree is 6 (look at 1st and last term)
Therefore, the answer is the second option:
2xy4 + 4x2y3 – 6x3y2 – 7x4
The value of the derivative of functions h'(6) as requested in the task content is; 55.
<h3>What is the value of h'(6)?</h3>
Since it follows from the task content that the function h(x)=4f(x)+5g(x)+1.
Hence, the derivative of h(x) can be evaluated as;
h'(x)=4f'(x)+5g'(x)
On this note, by substitution, it follows that;
h'(6)=4(5)+5(7)
h'(6) = 55.
