If A(x', y') & B(x",y") the the distance AB is given by the following formula:

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

Which transformations are needed to change the parent cosine function to y= 3cos(10(x-pi) )?
denpristay [2]
<span>The parent cosine function can be transformed and translated. So, from the basic function cos(x) we can obtain function acos(bx+c). In our case, a=3- amplitude, b=10- the period change and c=-pi- the phase shift. So, the parent cosine function is mutiplied with 3 (which gives the amplitude of the function, 3*0.5=1.5). The period of the function is changed, and is 2pi/b=2pi/10=pi/5 and the cos(x) is phase shifted for c/b=-pi/10.</span>

Y=10x+2<br> y=8x+2x+2<br> How many solutions
Luba_88 [7]
Simplify y=8x+2x+2: y=10x+2
Same as equation y=10x+2
Therefore it has infinitely many solutions

HELP!!! Solve the system of equation by graphing : y=x+3 , 2x+y= -6 : also how do you know if it’s substitution or elimination?
schepotkina [342]

Either would work, but substitution looks a bit easier.

The graph for these two is shown below.


I just put the equations in just as they are written. They did not have to be changed in any way. DESMOS is a wonderful program. Very powerful.


The blue line is 2x + y = - 6

The red line is y = x + 3


The best way to solve this other than a graph is to use substitution. Put the red graph into the blue one.

2x + y = - 6

2x +(x + 3) = - 6

2x + x + 3 = - 6

3x + 3 = - 6 Subtract 3 from both sides.

3x = - 6 - 3

3x = - 9

x = -9/3

x = -3


Now go back and solve for y

y = x + 3

y = -3 + 3

y = 0


Answer

The solution point is (-3,0) just what the graph shows.

As an estimation we are told £3 is €4.
Lesechka [4]

Answer:

£50.63

Step-by-step explanation:

If €4 = £3

Therefore one €1 = £3/4

Now, Converting  €67.50 to pounds,

67.50 * 3/4 =  £50.625

£50.63 (answer rounded to 2 DP)

Current time conversion,

67.50 Euro equals  60.68 Pound sterling
