The correct answer is D. Looking at the graph, we can see that the car travels for 2 hours (going up) and then stops. The line goes one unit across in a straight line, showing that it stopped for one hour. Then, our car starts up again and travels for another 2 hours, shown by going 2 units across. Hope this helps :)
Remember to use the graph to show understand what is going on.

Plot the zeros of the polynomial y = x4 + 3x3 − 27x2 + 13x + 42
a_sh-v [17]

Answer:

See explanation

Step-by-step explanation:

Consider the polynomial y=x^4+3x^3-27x^2+13x+42 4th power polynomial function has at most 4 zeros.

Integer zeros can be only among the divisors of 42:

\pm1, \ \pm 2,\ \pm 3,\ \pm 6,\ \pm 7,\ \pm 14,\ \pm 21,\ \pm 42

Check them:

y(1)=1^4+3\cdot 1^3-27\cdot 1^2+13\cdot 1+42=1+3-27+13+42=32\neq 0\\ \\y(-1)=(-1)^4+3\cdot (-1)^3-27\cdot (-1)^2+13\cdot (-1)+42=1-3-27-13+42=0\\ \\y(2)=2^4+3\cdot 2^3-27\cdot 2^2+13\cdot 2+42=16+24-108+26+42=0\\ \\y(3)=3^4+3\cdot 3^3-27\cdot 3^2+13\cdot 3+42=81+81-243+39+42= 0\\ \\y(-7)=(-7)^4+3\cdot (-7)^3-27\cdot (-7)^2+13\cdot (-7)+42=2,401-1,029-1,323-91+42= 0

Thus,

y=(x+7)(x+1)(x-2)(x-3)

Zeros are plotted in attached diagram.

Line AB passes through points A(-6,6) and B(12,3). If the equation of the line in slope-intercept form,
BabaBlast [244]

Answer:

The intercept is 5.

Step-by-step explanation:

Since we already have the slope of -1/6, we can use that and either point in point-slope form to get the equation in slope-intercept.

y - y1 = m(x - x1)

y - 3 = -1/6(x - 12)

y - 3 = -1/6x + 2

y = -1/6x + 5

Therefore, b= 5
