Answer:
x=1
Step-by-step explanation:
if the zeroes are (-2,0) and (4,0), then the axis of symetry is going to be right in the middle of those two, with the graph reflected equally on either side.
so you get:
(4-2)÷2=1
therefore the equation of the axis of symetry is x=1
Answer:
2,3,6
Step-by-step explanation:
5,226 ...(1)
unit digit=6
6 is divisible by 2,
so (1) is divisible by 2.
last two digits=26 ,not divisible by 4,
so (1) is not divisible by 4.
5+2+2+6=15 divisible by 3 but not divisible by 9.
so (1) is divisible by 3 but not divisible by 9.
2×3=6,so (1) is divisible by 6.
unit digit=6≠0 or 5
so (1) is not divisible by 5 or 10.
3.14 by 3.57 just divide those numbers by 14 and round to the hundredths place
Answer:
(5, - 4 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = - 2 → (1)
3x - y = 19 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the y- term
9x - 3y = 57 → (3)
Add (1) and (3) term by term to eliminate y
(2x + 9x) + (3y - 3y) = (- 2 + 57), that is
11x = 55 ( divide both sides by 5 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (1)
2(5) + 3y = - 2
10 + 3y = - 2 ( subtract 10 from both sides )
3y = - 12 ( divide both sides by 3 )
y = - 4
Solution is (5, - 4 )
Answer:
Second and fourth
Step-by-step explanation:
A line is in point-slope form when you write down as 
- do not be distracted by the signs, +1 and +5 can both be written as -(-1) or -(-5) rispectively.
