To add them, you first need a common denominator.
So multiply <span> 1/4 by 5/5 and 1/5 by 4/4 first. 

Now they'll be 5/20 and 4/20. 

Add them to get 9/20. </span>

daser333 [38]
Hello,

If R(4,0) is the given point and m=5 the slope,

y-0=5(x-4)==>y=5x-20 is the reduced form
and 5x-y-20=0 is the standard form

Please help !!<br> Solve the system of equation <br><br> Y=8x<br> Y= 2x+54
Finger [1]

Answer:

(9,72)

Step-by-step explanation:

Since both equations equal y, set the equations equal to each other and solve for x.

8x=2x+54 Subtract 2x from both sides

6x= 54 Divide both sides by 6

x=9

Substitute x=9 into either equation and solve for y

y=8(9)

y=72

Help and please explain so I can do it on my own. There are a couple more on this sheet.​
Andreas93 [3]

Answer:

(2, -10)

Step-by-step explanation:

so first i find the axis of symmetry using the equation x= -b/2a

in this problem

a=3

b= -12

c= 2

- (-12)/ 2(3) = 2

2 will be the x point for your vertex

you then plug in your x point into the original equation and solve for y

y = 3(2)^2 - 12(2) +2

y = -10

Vertex is then (2, -10)
