Answer:
-7
Step-by-step explanation:
-2(x+5)=4
open the bracket with -2
-2x - 10 = 4
combine the like terms
-2x = 4 + 10
-2x = 14
divide by -2
-2x/-2 = 14/-2
x = -7
Answer:
4/1
Step-by-step explanation:
8/8=1, so 32/8=4
Answer: B
Step-by-step explanation:
Step-by-step explanation: Find the slope using the formula m = StartFraction x 2 minus x 1 Over y 2 minus y 1 EndFraction, and then substitute one point and the slope into the equation y = m x + b to find the y-intercept.
Answer:
y=140°
Step-by-step explanation:
Method 1.
The exterior angle theorem tells us that y=20+120=140
Method 2.
Solve for x first., then use that to solve for y.
The sum of the interior angles of a triangle is 180, so we can get x by doing 180-20-120=40.
y and x make a straight angle which is 180°, so we can get y by doing 180-40=140
The Greates Common Factor (GCF) is: 2 x 2 x 2 = 8
