Answer:

x = -8

y = 9

Step-by-step explanation:

to solve this expression using simultaneous equation, we would say let

y =9............................................. equation 1

 6x + 5y =-3............................................equation 2

substitute equation 1 into equation 2

-3 = 6x + 5y............................................equation 2

6x + 5(9) = -3

6x + 45 = -3

collect the like terms

6x = -3-45

6x = -48

divide both sides by the coefficient of x which is 6

6x/6 = -48/6

x = -8

therefore y = 9

x = -8

BRAINLIEST!!!<br> 2. Determine whether each pair of triangles is similar. Justify your answer.
SIZIF [17.4K]

Answer:

the correct answer is option A.

Step-by-step explanation:

given that JK parallel to MN.

therefore angle JKL = angle LMN

and angle KJL = angle LNM

also angle JLK = angle MLN since vertically opposite angles.

we can say that triangle JLK ~ triangle NML.

as angle K coincides with angle L and angle J coincides with angle N

8x - 3y &lt; 4<br> 9.x + 2y &lt;-1<br> is (5, -5) a solution of the system?
mariarad [96]

Answer: 4x − 2y = 6 . . . . . (1)

2x + y = 5 . . . . . (2)

(2) x 2 => 4x + 2y = 10 . . . . . (3)

(1) - (3) gives: -4y = -4

y = -4/-4 = 1

From (2), 2x + 1 = 5 => 2x = 5 -1 = 4

x = 4/2 = 2

Solution is (2, 1)

Substituting the solution into the options gives that

−4x − 2y = 10

−4y = 4 −4x

has the same solution.

hope this helped!! :)

Based on the graph, what is the initial value of the linear relationship?
yuradex [85]

Answer:

The initial value of the linear relationship is y=-2

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

The initial value is the value of the linear function when the value of x is equal to zero

therefore

The initial value is the y-coordinate of the y-intercept of the linear function

Observing the graph

The y-intercept is the point (0,-2)

so

For x=0

The value of y is equal to y=-2
