10x + 2y = -2

2y = -10x - 2

y = (-10/2)x - 2/2

y = -5x - 1...the slope here is -5...a parallel line will have the same slope.

y = mx + b

slope(m) = -5

(0,12)...x = 0 and y = 12

now we sub...we r looking for b, the y intercept

12 = -5(0) + b

12 = b

so ur parallel line is : y = -5x + 12

2y = -10x - 2

y = (-10/2)x - 2/2

y = -5x - 1...the slope here is -5...a parallel line will have the same slope.

10x + 2y = -2

2y = -10x - 2

y = -(10/2)x - 2/2

y = -5x - 1 y = mx + c, slope m = -5.

If it is parallel, then the slope of the second line ought to be -5 as well.

So you should fill -5 in the bracket.

**Answer:**

Second figure is an example of perpendicular lines.

**Step-by-step explanation:**

The perpendicular lines are those that forms at the base of the vertical line.

The straight lines denotes the angle

The first figure is not correct both are intersecting tilted lines.

The second figure is correct since they form right angle that is angle.

The third figure is again tilted lines hence, not correct.

The fourth figure is again tilted lines hence, not correct.

therefore, second figure is correct.

To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20

It has to be equated to zero and the values of x are the x-intercepts. So,

4x2 – 24x + 20 = 0

The resulting equation is a quadratic equation which can be solved by different methods. The solution is

x = 5, 1

The average therefore is:

(1+5/)2 = 3

In the question "This figure shows the procedure for constructing a" The correct answer is "bisector of an angle" (option C).
To construct an angle bisector: Draw an arc that is centered at the vertex of the angle to intersect both sides of the angle. From the point of intersection of the previous arc and the both sides of the angle, draw two more arcs to intersect at a point. The radius for the two arcs must be equal. Then draw a straight line from the point of intersection of the later set of arcs and the vertex of the angle.

QUESTION POSTED AT 29/01/2020 - 05:17 PM

**Answer:**

The correct answer is **C.**

**Step-by-step explanation:**

Notice that the difference between consecutive values of x is always 1, and the difference between consecutive values of y is always 2. This means that

where and stands for two consecutive values of x, and the same goes to y.

Now, notice that this is the definition of the slope of the equation of a line. Then, a line can be characterized by this condition, and that is why **C ** is the correct answer.

Anyway, you can check that this set of point is generated by a linear function in other way. Suppose that it can be done, and the linear function has the form

.

From the pair (0,7) we deduce that , then . Now, substituting the pair (-3,1) we get and as consequence . Thus, if the points are generated by a linear function, its expression would be .

Now, substitute the different values of x and check that the same values of y are obtained.

**Answer:**

The correct option is B.

**Step-by-step explanation:**

It is given that the ordered pairs below represent a linear relation between x and y. (-3,0), (-2,4), (-1,8), (0,12), (1,16), (2,20).

At y-intercept the value of x is 0. From the given points we can say that the y-intercept of the function is (0,12).

If a line passing through the two points, then the slope of the function is

The slope of the function is

**Therefore the slope of the line represented by this table is 4 and the y-intercept is 12. Option B is correct.**

x = 400 / sin (7)

So we need to get the value of x.
