Answer:
-6 and 7
Step-by-step explanation:
-6 * 7 = -42 and -6 + 7 = 1, so they are factors and have a sum of 1.
The formula for a vertex form equation is

in which (h,k) represents the vertex
Your equation is in vertex form, if you mpve the -7 to the other side you will get

because you have to add 7 to both sides
based on the equation,
h=10
k=7
(h,k)=(10,7)
your vertex is (10,7)
Answer:
x=40
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+102+38 = 180
Combine like terms
x + 140 = 180
Subtract 140 from each side
x+140-140 = 180-140
x = 40
Y = -2x - 2...the slope here is -2. A parallel line will have the same slope.
y = mx + b
slope(m) = -2
(4,5)...x = 4 and y = 5
now we sub and find b, the y int
5 = -2(4) + b
5 = -8 + b
5 + 8 = b
13 = b
so ur parallel equation is : y = 2x + 13
