Answer:
f(3) just means to substitute 3 in for x.
Step-by-step explanation:
f(3) just means to substitute 3 in for x.
f
(
3
)
=
−
2
Explanation:
f
(
3
)
=
−
(
3
)
2
+
7
According to the order of operations, first square the 3, which is 9.
f
(
3
)
=
−
9
+
7
The negative sign in front of the x squared is equivalent to multiplying by negative one.
Add -9 and 7 together, which is -2
So,
f
(
3
)
=
−

9, 14, and 22.
The formula for checking if a triangle will work is side a + side b > side c.
The only one that works is 9, 14, and 22.
Answer:
Area = 32feet²
Step-by-step explanation:
Perimeter of a rectangule = 2(length+width)
Then:
g = 2w Eq. 1
2(g+w) = 24 Eq. 2
g = length
w = width
From Eq. 2:
(2*g + 2*w) = 24
2g + 2w = 24
2w = 24 - 2g Eq. 3
Matching Eq. 1 and Eq. 3
g = 24 - 2g
g + 2g = 24
3g = 24
g = 24/3
g = 8 feet
From Eq. 1
g = 2w
8 = 2w
8/2 = w
w = 4 feet
Check:
From Eq. 2
2(g+w) = 24
2(8+4) = 24
2*12 = 24
Answer:
Area of a rexctangle = length * width
Then:
Area = 8feet * 4feet
Area = 32feet²
Hi so to awnser this you need to first put it in a table.. And then see what you have to do to go from x to y. Let me know if you need anymore help.
