2x – y = 6 5x + 10y = –10
Studentka2010 [4]
2x-y=6;5x+10y=-10. -y=-2x+6. -y/-1=-2x+6/-1. y=2x-6. 5x+10y=-10. 5x+10(2x-6)=-10. 25x-60=-10. 25x=50. 25x/25=50/25. y=2x-6. y=(2)(2)-6. y=-2. Therefore, x=2 and y=-2

can someone help me please? Lines AB and CD are perpendicular to each other. If 1 measures (3x + 3)°, and 2 measures 39°, what i
tester [92]

Answer:

x = 16

Step-by-step explanation:

Angle 2 is equal to 39, which means that Angle 1 has to be 51, since Angles 1 and 2 together is a right angle

3x+3=51

Subtract 3, making it 48

Now do 48 divided by 3, and you get 16

Alisha has a $15,000 car loan with a 6 percent interest rate that is compounded annually. How much will she have paid at the end
Tpy6a [65]
6 percent intrest per year for 5 years I think is the same as 30 percent for 5 years

so $15,000 x .3 is $4500

$15,000 + $4500 = $19,500

not 100 percent sure if this is correct but I think its right. Sorry if im wrong.

I need how you found the answers?
lara31 [8.8K]

Answer:

2x + 6 = -18

x + 1 = -11

3x = -36

Step-by-step explanation:

First find the solution! Then you can create your own equations

2x+9=-15

2x=-24

x=-12

Thus u need solutions with:

x = -12

Knowing the equation of a line as:

y = mx + b

we can can start by making y = -12 (our solution)

mx + b = -12

Now we can pick a value for m and b by adding and miltiplying on both sides

We do this to keep both sides equal.

if we make m = 2 and b = 3:

2x + mb = -12*m + 2b

2x + 6 = -24 + 6

2x + 6 = -18

Solving this we also get x = -12, as we expect.

An alternative way to think about it is to imagine that we start with a simple equation and make it more complex. We have our solution:

x = -12  => lets add a b value!

x + b = -12 + b => Lets add a slope (m)

xm + bm = -12m + bm

Giving values for this can give you multiple equation of the same solution.

General Formula:

m(x+b) = m(y+b)

mx + bm = my + bm
