PLZ GIVE BRAINLEIST
The vertex is (8,7)
the minimum value is 7
the vertex form is y=(x-8)^2 +7
the minimum value of y=7
i hope this helps!
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10
<em>add 10 to each side</em>
<em>5x-10+10 = 10 + 10</em>
<em>5x=20</em>
5x = 0 <em>this is the error</em>
He needs to add 10 to each side
Answer:
y=-9/2x plus 4
Step-by-step explanation:
y=ax plus b
Use points from the task.
4=0x plus b
so b=4
-5=-2a plus 4
-2a = -9
a = -9/2
y=-9/2x plus 4
The answer is B! Good luck!
