-5a + 3 > 1 what’s the equation

1 answer:

7 0

Start by subtracting 3 from both sides to get -5a > -2. then divide both sides by -5 to get a < 2/5, as dividing by a negative switches the sign.

X=-12-6y <br>-4x+5y=-39<br>slove by the system of substitution

Artist 52 [7]

X = -6y - 12
4x + 5y =-39

4x + 5y = -39
-4(-6y - 12) + 5y = -39
-4(-6y) + 4(12) + 5y = -39
24y + 48 + 5y = -39
29y + 48 = -39
29y = -87
y = -3

x = -6y - 12
x = -6(-3) - 12
x = 28 - 12
x = 6

(x, y) = (6, -3)

Katarina [22]

Answer:

m∠CFD= $105\°$

Step-by-step explanation:

we know that

m∠CFD+m∠DFE= $180\°$ ------> by supplementary angles

we have

that

m∠DFE=m∠DEF= $75\°$

m∠CFD+ $75\°=180\°$

m∠CFD= $180\°-75\°=105\°$
