1. Split the second term in 6x^2 - 11x - 35 into two terms

6x^2 + 10x - 21x - 35

2. Factor out common terms in the first two terms, then in the last two terms

2x(3x + 5) - 7(3x + 5)

3. Factor out the common term 3x + 5

(2x - 7)

Line JK passes through points J(–4, –5) and K(–6, 3). If the equation of the line is written in slope-intercept form, y = mx + b

4vir4ik [10]

The value of "b" is the y-intercept.

In order to figure out slope-intercept form you need 1 coordinate and the slope.
1) Find the slope, using the 2-point slope formula: "m= y2-y1 / x2-x1".
ex. m= -5 - 3 / -4 - -6 (simplify)---> m= -4

2) Fill in the blanks for point-slope formula: "y - y1 = m (x - x1)"
(choose one coordinate, it doesn't matter which one)
ex. y - -5 = -4 (x - -4)

3) Then use basic algebra to simplify.

Someone help on this one please

Answer:

B. Multiply each x-value in the table by -1.

Step-by-step explanation:

A point reflected across the y-axis has the same y-value, but the x-value is replaced by its opposite. For example, (-2, -31) reflected across the y-axis becomes (2, 31).

The appropriate choice is ...

... B. Multiply each x-value in the table by -1.

Comment on the graph

The purple points are the ones in the given table. The red points are the same with their x-coordinate multiplied by -1. You can see that they are the reflection of the purple points across the y-axis. The lines joining the points are to help you see the points and which data set they are in.

f(x)= -2x+1 {-2,0,2,4,6}

If x=-2, then -2(-2)+1 = 5

If x=0, then -2(0)+1 = 1

If x=2, then -2(2)+1 = -3

If x=4, then -2(4)+1 = -7

If x=6, then -2(6)+1 = -11

Answer:

B {5,1,-3,-7,-11}

1. Find the distance between two

BigorU [14]

Answer:

$\mathrm{D)\:}9.4\: \mathrm{units}$

Step-by-step explanation:

Solution 1:

Notice the $x$ coordinate of both points are equal, meaning both points are on a vertical line. The distance between two points on a vertical line is the absolute difference of their y-coordinates. The absolute difference between $4.7$ and $-4.7$ is $|4.7-4.7|=\fbox{$9.4$}$ .
