Answer:

Step-by-step explanation: this equation works when you are given two points

$\frac{y_{2}-y_{1} }{x_{2} -x_{1} } =slope$

$\frac{9-4}{-3-(-4)} =\frac{5}{-3+4} =\frac{5}{1}=5$

Sistema de ecuaciones.5x+2y=-152x-2y=-6

Zolol [24]

Tnemos el sisema de ecuaciones:

$\begin{gathered} 5x+2y=-15 \\ 2x-2y=-6 \end{gathered}$

Podemos resolverlo por eliminación sumando ambas ecuaciones y eliminando y. Asi podemos resolver para x:

$\begin{gathered} (5x+2y)+(2x-2y)=(-15)+(-6) \\ 7x+0y=-21 \\ x=-\frac{21}{7} \\ x=-3 \end{gathered}$

Ahora podemos resolver para y con cualquiera de las dos ecuaciones:

$\begin{gathered} 2x-2y=-6 \\ 2\cdot(-3)-2y=-6 \\ -6-2y=-6 \\ -2y=-6+6 \\ -2y=0 \\ y=0 \end{gathered}$

Respuesta: x=-3, y=0

Use the graph to state the solution for the system.

svlad2 [7]

Use the graph to state the solution for the system.x + 2y = 4 (line a)
 3x – 2y = 4 (line b)C.

8 + 5 x (11 - 5) - 9 Please help me

Natali [406]

I got 60 as my answer

you ALWAYS do your parentheses first

then you do 8+5 and that equals 13•6-9

13 times 6 is 78. then you subtract 9 which will leave you with 60. hope that helped ☺️
