Answer:
Here we want to complete the blank to make the equality true:
( ) = (2 - 6)*(-4)
The equality is true if we have the same value in both sides, so we can think of this as an algebraic equation:
x = (2 - 6)*(-4)
We just need to find the value of x.
Then let's solve the right side:
x = (2 - 6)*(-4) = (-4)*(-4)
Remember the rule of signs:
(-)*(-) = (+)
x = (-4)*(-4) = 4*4 = 16
Then we need to complete the blank with the number 16
(16) = (2 - 6)*(-4)
Answer:
the domain of the function are {-3/2, 3/2, 3}
Step-by-step explanation:
f(x)=2x+1
range=-2, 4, 7
f(x)=-2
or, 2x+1=-2
or, x=-3/2
f(x)=4
2x+1=4
or, x=3/2
f(x)=7
2x+1=7
or, x=3
Answer:
Equation 1
6*a = 360°
Equation 2
2*a + 2*b = 360°
a = 60°
b = 120°
Step-by-step explanation:
From the first picture we can see that 6 angles a° made a complete circle, that is, 360°. So:
6*a = 360°
a = 360°/6 = 60°
From the second picture we can see that 2 angles a° and 2 angles b° made a complete circle, then:
2*a + 2*b = 360°
2*b = 360° - 2*60°
b = 240°/2 = 120°
