-4x both sides

2y=-4x-16

2y/2=-4x/2-16/2

y=-2x-8

so it's A

2y=-4x-16

2y/2=-4x/2-16/2

y=-2x-8

so it's A

Y = kx

We have to find k value, so lets say x is euros and y is American dollars

so we have

9 = k(8)

k = 1.125

so the equation will be y = 1.125x

to prove it use another value given

y = 1.125x

y = 1.125 (24)

y = 27

Thus 24 euros is 27 dollars.

Hence the equation y =1.125x is correct.

**Solution:**

X 4 8 12 16 20

F(x) 11 25 16 9 31

A function is said to be increasing if ,

As you can see from the table given as x increases , f(x) increases as well as decreases.

So it is increasing as well as decreasing function.

Now plotting the graph on two dimensional coordinate plane and drawn perpendicular from these points on X axis.

Equation of line joining two points

Equation of line joining two points (4,11) and (8,25) is

4(y-11)=14(x-4)

4 y -44 = 14 x -56

4 y = 14 x -12

y= --------(1)

Area under line (1) is

Equation of line joining (8,25) and (12,16) is

4(y-25 )= -9(x-8)

4 y - 100= -9 x + 72

4 y = -9 x + 172

y = --------(2)

Area under line 2 is

Equation of line joining (12,16) and (16,9) is

-4(y-16) = 7(x-12)

-4 y + 64= 7 x -84

-4 y = 7 x -148

y = -----------(3)

Area under the line 3 is

Equation of line joining (16,9) and (20,31) is

4(y-9) = 22(x-16)

4 y - 36 = 22 x - 352

4 y = 22 x - 316

y= ---------(4)

Area under the line 4 is

Total Area = Area under the line (1+2+3+4)

=

= 72 +82+50+80

= 284 square units

You can find area using the formual of area of trapezoid which is = [Sum of parallel sides]× [perpendicular distance between them]

QUESTION POSTED AT 23/09/2019 - 04:23 AM

To rewrite in slope-intercept form, solve for y. This is because slope-intercept form is y = mx + b, and the equation has y by itself.

5x - 2y - 7 =0

-2y = -5x + 7

y = (5/2)x - 7/2

5x - 2y - 7 =0

-2y = -5x + 7

y = (5/2)x - 7/2

To find y intercept form, use given point and slope and put it in this form,

y = mx+c

m = (y2-y1)/(x2-x1)

To find y intercept form, use given point and slope and put it in this form,

y = mx+c

QUESTION POSTED AT 23/09/2019 - 04:20 AM

There will always be a point symmetrical to the given point on the other side of the parabola.

To find that other point, know that the perpendicular distance to the line of symmetry is the same for both points.

The perpendicular (shortest) distance from (-5,6) to the line x = -2 will be to the point (-2,6) on that line.

The perpendicular (shortest) distance from (-5,6) to the line (-2,6) is the change in x coordinates, or absolute value difference in x coordinates. |-5--2| = 3.

Then go 3 units to the right of (-2,6) to find the other point because the other symmetrical point also is the same distance to the middle point (-2,6). The answer is (1,6)
