Answer:
4/10
Step-by-step explanation:
in plain and short, to graph an inequality, we first graph its EQUALITY graph, and then we do the shading.
so to graph y > x + 3, we first graph y = x + 3, which is just a line, and then do a true/false check on a point to see which side we shade.
let's hmmm check the point say (0,2), x = 0, y = 2.
y > x + 3
2 > 0 + 3
2 > 3 <--- is that true? is 2 really larger than 3? nope, so is false.
that simply means that the point (0, 2) is on the false area, so that's the area we do NOT shade, so <u>we shade the other side</u>.
y > x + 3, means "y" is greater than or larger than that line, but not equals, larger not equal, meaning the values on the borderline are not included, so the line is a dashed line.
check the picture below.
Answer:
C.(-5, 4)
Step-by-step explanation:
The vertex form of a parabola of this type is:
y
=
a
(
x
−
h
)
2
+
k [1]
where (
h
,
k
) is the vertex.
Explanation:
Given:
y
=
7
(
x
+
5
)²
+
4 [2]
We can convert equation [2] into the same form as equation [1] by writing
+5 as
−
−
5
:
y
=
7
(
x
−
−
5)
²
+
4 [3]
We observe that the vertex is
(
−
5
,
4
)
hope it will help :)
Needing to find the circumference of a circle you you find that you need to use the equation C=2 π R
C= 28.26
this is how much fence they would need around the garden approximately.
