Answer:
0
Step-by-step explanation:
Answer:
When a trinomial is in the form of ax2 + bx + c, where a is a coefficient other than 1, look first for common factors for all three terms. Factor out the common factor first, then factor the remaining simpler trinomial. If the remaining trinomial is still of the form ax2 + bx + c, find two integers, r and s, whose sum is b and whose product is ac.
Step-by-step explanation:
Answer:
A lies on (1,3) a reflection across the y-axis is (x,y) to (-x,y). The x turns the opposite and y stays the same so...
(-1,3)
Answer:
The second one.
Step-by-step explanation:
3 -

=

- 7
First, simplify

to

/ Your problem should look like: 3 -

=

- 7
Second, simplify

to

/ Your problem should look like: 3 -

=

- 7
Third, multiply both sides by 9 (the LCD of 9,3). / Your problem should look like: 27 - 2b = 3b - 63
Fourth, add 2b to both sides. / Your problem should look like: 27 = 3b - 63 + 2b
Fifth, simplify 3b - 63 + 2b to 5b - 63. / Your problem should look like: 27 = 5b - 63
Sixth, add 63 to both sides. / Your problem should look like: 27 + 63 = 5b
Seventh, simplify 27 + 63 to 90. / Your problem should look like: 90 = 5b
Eighth, divide both sides by 5. / Your problem should look like:

= b
Ninth, simplify

to 18. / Your problem should look like: 18 = b
Tenth, switch sides. Your problem should look like: b = 18
Answer:
b = 18
