Answer:
i dont what it could be but my uncle said it was 32 but i dont know if its correct
Step-by-step explanation:
Answers: b, d and e
b.The graph has a relative minimum
d. The graph has an x intercept at 3,0
e. the graph has an y intercept at 0,-15
f(x)=(x+5)(x-3)
The given equation is in the form of f(x) = a(x-b)(x-c)
If 'a' is positive then graph has a relative minimum
If 'a' is negative then graph has a relative maximum
Here a=1 that is positive so graph has a relative minimum .
To find x intercept we set f(x) =0 and solve for x
0=(x+5)(x-3)
x+5 =0 -> x = -5 so x intercept is (-5,0)
x - 3=0 -> x= 3 so x intercept is (3,0)
To find y intercept we plug in 0 for x
y=(x+5)(x-3)
y=(0+5)(0-3) = -15
so y intercept is (0,-15)
Answer:
YZ = 18.4 in
Step-by-step explanation:
The midsegment YZ is half the length of the third side VX , then
YZ = 
× 36.4 = 18.2
Answer:
y = -x + 4
Step-by-step explanation:
x + y = 6 => y = -x + 6
The line that parallel to y = -x + 6 has same slope so m = -1
Using coordinates (-4,8)
y = mx + b
8 = (-1)(-4) + b
8 = 4 + b
b = 4
then y = -x + 4
Answer:
9
Step-by-step explanation:
The two triangles 
.
Therefore the corresponding sides are proportional.
From the diagram |MP|=4, |PN|=3, |MN|=5 |ST|=x and |TR|=12.
Let us substitute the values and solve for x.
Multiply both sides by 3 to get:
This implies that:
Therefore x=9
