What is the domain? I think it’s (-4,-3)
Olin [163]

Answer:

all real numbers

Step-by-step explanation:

As the graph goes up, it keeps going up and to the right. There is nothing telling us it will stop moving to the right at a certain point. It goes up much faster than it goes right, but it keeps going right and up forever. That makes the domain reach positive infinity. The same happens on the left side. As it goes down to the left, it keeps going left forever to negative infinity. That makes the domain all real numbers from negative infinity to positive infinity.

Domain: all real numbers

Which statement describes the graph of the system of equations?
qwelly [4]

Answer:

The lines are parallel.

Step-by-step explanation:

The first line is x-y=1

In slope-intercept form, this line has equation: y=x-1

The second line is y-x=1

In slope-intercept form, the line has equation: y=x+1

The slopes of the two lines are the same (m=1)

however, the y-intercepts of these lines are different (-1) and (+1) respectively.

The first choice is correct.

The two lines are parallel and hence will never intersect.

Solve the system of equations. \begin{aligned} & -5x+13y = -7 \\\\ & 5x+4y=24 \end{aligned} ​ −5x+13y=−7 5x+4y=24 ​ x= e
riadik2000 [5.3K]

Answer:

The solution of the given equations

x =4 , y = 1

Step-by-step explanation:

<u>Explanation</u>:-

<u>Step(l</u>):-

Given the system of equations -5x+13y = -7 ..(l)

                                                     5x+4y=24 ..(ll)

<u>Step(ll)</u>

Adding (l) and (ll) equations and cancelling '5x' terms we get

         13y+4y = -7 +24

               17y = 17

dividing '17' on both sides, we get

                y=1

<u>Step(lll):-</u>

Substitute y=1 in equation (l) , we get

-5x+13y = -7

-5x + 13(1) = -7

subtracting '13' on both sides, we get

-5x +13 -13= -7 -13

-5x = -20

Dividing '-5' on  both sides, we get

x = \frac{-20}{-5}

x = 4

<u>Conclusion</u>:-

The solution of the given equations

x =4 , y = 1
