Answer:

B. zero

Step-by-step explanation:

Lines with negative slopes slant downward from left to right

Lines with positive slopes slant upward from left to right.

Lines with undefined slopes are vertical lines.

Lines with zero slopes are horizontal lines.

This is a horizontal line, so it must have a slope of zero. This is because it is a horizontal line, and the y-coordinate never changes.

A forest fire covers twice the amount of forest as it did 3 days ago. 3 days ago, this fire covered 300 square miles and it cont

alisha [4.7K]

Answer:

The correct option is B) 4800 square miles.

Step-by-step explanation:

Consider the provided information.

It is given that the fire covered 300 square miles in 3 days ago. And it continues to grow at the same rate.

Therefore, today it covers the twice of area it covers on yesterday.

The area covers by fire 2×300=600 square miles

Now the area covers after 3 days from today will be:

2×2×300 = 2×600 = 1200 square miles

The area covers after 3×2=6 days from today is:

2×2×2×300 = 2400 square miles

The area covers after 3×3=9 days from today is:

2×2×2×2×300 = 4800 square miles

Hence, the correct option is B) 4800 square miles.

11. What is the location of the vertex of the parabola defined by f(x) = −3x2 − 18x − 35 and in what direction does the parabola

lbvjy [14]

11. The given parabola has equation: $f(x)=-3x^2-18x-35$

We complete the square to have the function in the vertex form: $f(x)=-3(x^2+6x)-35$

$f(x)=-3(x^2+6x+9)+3*9-35$

$f(x)=-3(x^2+6x+9)+27-35$

$f(x)=-3(x+3)^2-8$

The vertex is (-3,-8), the graph opens down because a=-3<0

Ans: B. Vertex: (−3, −8), opens downward

12. We know the graph of $y=x^2$ is a parabola that opens up and has its minimum point at the origin.

The range of this function is $y\ge 0$

A straight line that has its y-intercept below the x-axis (y=3x-6) will not intersect $y=x^2$ and hence will form a system with no solution.

Ans: D. y equals x squared, y equals 3x minus 6

14. We want to find the zeros of $x^2+21x=5x-63$

$x^2+21x-5x+63=0$

$x^2+16x+63=0$

The factored form is $(x+7)(x+9)=0$

$x=-7\:or\: x=-9$

Ans: C. x = −7, −9

15. The given quadratic expression is $6x^2-17x+10$

We split the middle term to obtain:

$6x^2-12x-5x+10=0$

We factor by grouping to get:

$6x(x-2)-5(x-2)=0$

$(x-2)(6x-5)=0$

Ans: D. 6x − 5
