we have

y=-\frac{5}{2}x-7 ------> equation A

x+2y=4 ------> equation B

we know that

The intersection point both graphs is the solution of the system of linear equations

Using a graphing tool

see the attached figure

The solution is the point (-4.5,4.25)

therefore

the answer is the option A

(-4.5,4.25)

Find the values of x and y
pantera1 [17]

Answer:

x = 15°

y = 59°

Step-by-step explanation:

Angles at a right angle add up to 90°

41 + y = 90

y = 90 - 41

y = 59°

Angles in a triangle add up to 180°

41 + (2x - 9) + 7x + 13 = 180

41 + 13 - 9 + 2x + 7x = 180

45 + 9x = 180

9x = 180 - 45

9x = 135

x = 135/9

x = 15°

Somebody please help me with these problems and show me the steps teacher didn’t really help and it’s 2 step equations with frac
Andre45 [30]

5 1/2 - u = 9/4          U= 13/4

Basically you have to get the variable (u) by itself. Doing this by doing the opposite of what it’s doing to both sides of the equation.
