6x + y = -2 y= -3x + 1 Graph the solution

Gala2k [10]

6x + y = -2
y = -3x + 1

Substitute the value of y in first equation,
6x -3x + 1 = -2
3x = -2-1
x = -3/3
x = -1

Now, Substitute it in 2nd equation,
y = -3(-1) + 1
y = 3+ 1 = 4

Coordinates would be: (-1,4) Mark that point and join with origin.

Hope this helps!

Show any calculations, including 180 degrees, go step by step pls.

ICE Princess25 [194]

Answer:

120°, 120°, 60°, 60°

Step-by-step explanation:

m∠1 = 180° - 60° = 120°

m∠1 = m ∠2 (alternate interior)

m∠3 = 60° (vertical to given angle)

m∠4 = m∠3 (alternate exterior)

The formula F = 1.8C + 32 gives the temperature in degrees Fahrenheit (F) for a given temperature in degrees Celsius (C). There

Answer:

-40 °F = -40 °C

Step-by-step explanation:

(1) F = 1.8 C + 32

If the Fahrenheit and Celsius temperatures are the same, then

(2) F = C Substitute (2) into (1)

C = 1.8C + 32 Subtract 1.8 C from each side

C – 1.8 C = 32 Combine like terms

-0.8C = 32 Divide each side by -0.8

C = -32/0.8

(3) C = -40 Substitute (3) into (1)

F = 1.8(-40) + 32

F = -72 + 32

F = -40

So, -40 °F = -40 °C

The thermometer below shows that -40 °F = -40 °C.
