Answer:

C) It is the only solution to the system.

Step-by-step explanation:

3x + 3y = -30

2x + y = -17

3(-7) + 3(-3) = -30

-21 + -9 = -30

-30 = -30

True

2x + y = -17

2(-7) + (-3) = -17

-14 + -3 = -17

-17 = -17

True

The lines defined by the equations are not parallel and the point is a solution to both of them.
It must be the point of intersection so it is the only solution to the system

Solve the given one-step equations. Show your work.
laila [671]
Isolate for each variable.
1. z= 6 - 10
z= -4

2. y= 48/8
y=6

3. q= 1+12
q= 13
4. 18 x 2= a
36= a
5. r= 7 x 3
r= 21

I think you can try the rest :)

How can you analyze connections between linear equations and use them to solve problems
Alexeev081 [22]

Answer:

Step-by-step explanation:

One of the more obvious "connections" between linear equations is the presence of the same two variables (e. g., x and y) in these equations.

Assuming that your two equations are distinct (neither is merely a multiple of the other), we can use the "elimination by addition and subtraction" method to eliminate one variable, leaving us with an equation in one variable, solve this 1-variable (e. g., in x) equation, and then use the resulting value in the other equation to find the value of the other variable (e. g., y).  By doing this we find a unique solution (a, b) that satisfies both original equations.  Not only that, but also this solution (a, b) will also satisfy both of the original linear equations.

I urge you to think about what you mean by "analyze connections."

The probability of spinning a 4 on a spinner is 0.125.If you spun 150 times approximately how many times would the spinner land
Ksivusya [100]

Answer:

19

Step-by-step explanation:

To calculate this, all we need to do is 150 * 0.125 ≈ 18.75 which rounds to 19. We round to the nearest integer because you can't land on the 4 18.75 times.
