P=44.6
P=a+b+√a^2+b^2=11+15+√11^2+15^2≈44.6
Answer:
X < 9
Step-by-step explanation:
Add 1 to both sides
3 > x/3
multiply by 3 to get x by itself
9 > x
or
x < 9
Answer:
15 degrees lower
Step-by-step explanation:
When you are trying to find the difference between a negative and positive number, add both numbers and you will get the difference. In this case it was 15.
Sorry, math isn't my strongest suit, but i hoped this helped!
3x<18 I'm not sure what the rule for this problem is.
Answer: Second option: (4,0) and (-9,0)
f(x)=x^2+5x-36
The x-intercepts of the graph of a function f(x) are the values of the variable x that makes f(x)=y equal to zero. To find these values we only have to equal f(x)=y to zero:
f(x)=y=0
x^2+5x-36=0
Factoring the polynomial:
(x+9)(x-4)=0
Using that if a b=0, then: a=0 or b=0
with a=x+9 and b=x-4
x+9=0 or x-4=0
Solving for x:
x+9-9=0-9 or x-4+4=0+4
x=-9 or x=4
Then the x-intercepts are the poitns (x,y)=(x,0):
(4,0) and (-9,0)
