Answer:
y + 3 = 2(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (- 1, - 3), thus
y - (- 3) = 2(x - (- 1)), that is
y + 3 = 2(x + 1)
Answer:
b = S - a - c
Step-by-step explanation:
You just move every other term except for the one you're solving for to the other side, using the opposite operations
S = a + b + c
S - a = b + c
S - a - c = b
b = S - a - c
OR
S = a + b + c
-b + S = a + c
-b = -S + a + c
b = S - a - c (we flipped all signs here to make b positive, like it's supposed to be. The justification for this is multiplying both sides by -1)
Answer:
The corresponding point is (5,8)
Step-by-step explanation:
In this problem we know that
The rule of the transformation is equal to
(x,f(x)) ------> (x,f(x)+4)
so
for the point (5,4)
x=5, f(x)=4
substitute
(5,4) ------> (5,4+4)
(5,4) ------> (5,8)
therefore
The corresponding point is (5,8)
N / 2
400 / 2 = 200
200 / 2 = 100
100 / 2 = 50
50 / 2 = 25
25 / 2 = 12.5
Answer:
y = 11 1/2
Step-by-step explanation:
7y - 63 = y + 3
-y. -7
6y - 63 = 3
+ 63. + 63
6y = 69
/6. /6
y = 11 1/2
