Hamburgers cost $2 and hotdogs cost $2. The total cost of buying b hamburgers and d hotdoge can be expressed by C=3b+2d. how can

sveticcg [70]

C= 3b + 2d
Subtract 3b first.

C-3b = 2d
Divide by 2.

C-3b/2 = d

OR

C-3b
-------- = d Your final answer!
2

Answer:

4^3x=4^(4x+4)

Step-by-step explanation:

You can eliminate the first 2 options since those don’t make sense already, and the last option changed 64 to 2^6 which is correct, but when they changed the other side. They should have multiplied 8 to both x and 1 which would have made the whole term 2^(8x+8) and not 2^(8x+1). Left with the third option, 4 to the power of 3 is 64 so the left side makes sense, 4^3x=64^x, on the right side, 4^4 equals 256, so the whole exponent should multiply by 4 so from 256^(x+1) you get 4^4(x+1) giving 4^(4x+4) making the third choice the right answer.

Consider the following polynomial. - 2x * y ^ 5 + 3x ^ 7 - 10x ^ 3 * y ^ 6 + 8x ^ 6 + 4 Which of the following statements are tr

Salsk061 [2.6K]

Option a: polynomial has 5 terms.

Option c: The constant term is 4.

Explanation:

The polynomial is $-2xy^{5} +3x^{7} -10x^{3} y^{6} +8x^{6} +4$

Option a: Polynomial has 5 terms

From the polynomial, we have,

1st term = $-2 x y^{5}$

2nd term = $3 x^{7}$

3rd term = $-10 x^{3} y^{6}$

4th term = $8 x^{6}$

5th term = $4$

Hence, the polynomial has 5 terms.

Thus, Option a is the correct answer.

Option b: The leading coefficient is -2 and the degree of the polynomial is 7.

The leading coefficient is the coefficient of the variable with the largest degree.

The degree of the polynomial can be determine by the adding the powers of the variable.

degree of 1st term = $-2 x y^{5}$ = $1+5=6$

degree of 2nd term = $3 x^{7}$ $=7$

degree of 3rd term = $-10 x^{3} y^{6}$ $=3+6=9$

degree of 4th term = $8 x^{6}$ $=6$

degree of 5th term = $4$ $=0$

Thus, from these 5 terms the highest value is 9 which is the degree of the polynomial.

The polynomial $-2xy^{5} +3x^{7} -10x^{3} y^{6} +8x^{6} +4$ has a largest degree of 9 and the leading coefficient is -10.

Hence, Option b is not the correct answer.

Option c: The constant term is 4.

The constant term is a term in which variable will not occur.

From the polynomial $-2xy^{5} +3x^{7} -10x^{3} y^{6} +8x^{6} +4$ , we can see that the constant term is 4.

Hence, Option c is the correct answer.

Option d: Polynomial is in decreasing degree order

The decreasing degree order is the degree in which each term is no larger than the degree of the preceding term.

From the polynomial, we have,

degree of 1st term = $-2 x y^{5}$ = $1+5=6$

degree of 2nd term = $3 x^{7}$ $=7$

degree of 3rd term = $-10 x^{3} y^{6}$ $=3+6=9$

degree of 4th term = $8 x^{6}$ $=6$

degree of 5th term = $4$ $=0$

where the degree of the 3rd term is not less than the 4th term.

Thus, the polynomial is not in decreasing degree order.

Hence, Option d is not the correct answer.
