Answer:

Step-by-step explanation:

This is an even polynomial because both ends end up. This means the degree of the polynomial is even. This means b and c are not solutions since their degrees are odd.

To determine between A and D look at the x-intercepts. The x-intercepts of a polynomial graph have a special relationship with its equation. The x-intercepts are the solutions or roots of the factors. This means that when each factor is set equal to 0 and solved, its solution is an x-intercept. Here the x-intercepts are x = -1, 0,3. This means the factors are x(x+1)(x-3).

Notice at x = -1, the function touches but does not cross? This means the factor has an even exponent on it.

So the expression is likely x(x+1)^2 (x-3).

Since only one factor has an exponent, the answer is A.

M–[(m–n)÷(−2)](−5), if m=−4, n=−6

jeka94

Answer:

-9

Step-by-step explanation:

We are given the expression m–[(m–n)÷(−2)](−5). Substituting -4 for m and -6 for n, we get:

-4–[(-4 + 6)÷(−2)](−5)

We must do the work that appears inside parentheses first:

-4–[( 2 )÷(−2)](−5)

Next we must do the work that appears inside square brackets:

-4–[ -1 ](−5)

Multiplication comes next. The above expression becomes:

-4 - [ 5 ]

which in turn comes out to -9

Joe has a total of 14 pennies, dimes and quarters in his pocket, which total $1.52. The number of dimes and quarters combined is

Nonamiya [84]

<span><span>5 quarters 2 dimes and 7 pennies
</span>
You know that the quarters and dimes together equal to the pennies, do you divide the number of coins by half, from there you find how much money worth you have of quarters and dimes, using that you use : 0.25X+0.1Y=1.45, from there you common factor by 0.05 and you divide both sides by 5 cents and you get 5x+2y=29, from there you see that you have 5 quarters, 2 dimes and 7 pennies
