Answer:
Yes
Step-by-step explanation:
The negative sign was simply moved to either the numerator or denominator. Either way the number is still a negative one half.
Answer:
a) 2 -2 -4 -4 -2 2 8
b) graph B
c) x = -2.55 or x=1.55
Step-by-step explanation:
a) just fill in the x values
b) look at x=0, you'll find y=-4. Only graph B goes through (0, -4)
c) estimate where graph B passes through the x axis.
When 2 secants intersect a circle:
(DC + CE) * CE = (AB + BE) * BE
( 1 + (x+4)) * (x+4) = (11 + (x+1)) * (x+1)
x + x^2 + 4x + 4 +4x +16 = 11x +x^2 +x +11 +x +1
9x + 20 = 13x + 12
4x = 8
x = 2

Gee - that was a little bit of work!!
Answer:
Step-by-step explanation:
<2 and <8 are alternate exterior angles
<4 and <6 are alternate interior angles
<3 and <6 are corrosponding angles
The expression for the sequence of operations described below is d/3 + 5
<h3>Expressions and equations:</h3>
- Let the unknown value be "d"
- d divided by 3 is expressed as d/3
Adding 5 to d/3 to get the expression below;
g(d) = d/3 + 5
Hence the expression for the sequence of operations described below is d/3 + 5
