Mathematics
1 answer:
Sati [7]3 years ago

The answer is D, i.e. the system was solved via elimination


If you multiply the first equation by 5, the system becomes


\left \{ {{-5x-10y=35} \atop {5x-6y=-3}} \right.


If you sum the two equations, you get


-16y = 32


And so if you substitute the second equation of system A with this new equation, you'll get system B.

Depends on how much percent you have to put down for the house. Like if it’s 10% then just subtract 10% from the cost of the house.

Can someone help me out with these two problems having trouble please !!
eimsori [14]

Answer:

1.

x=-10

x=-6

2.

x=10

x=-3

Step-by-step explanation:

to find the zeros of a function you need to set it equal to zero:

x^2+16x+60=0

then you factor

(x+10)(x+6)=0

then you have to finish factoring/simplifying

x+10=0

  -10

x=-10

x+6=0

 -6

x=-6

and the same thing for number 2

x^2-7x-30=0

(x-10)(x-3)=0

x=10, x=3
