Answer:
800 mm or 80 cm
Step-by-step explanation:
We are given that Jessica is measuring two line segments.
Length of first line segment =30 cm
Length of second line segment=300 mm
We have to find that Length of two line segments together
We know that 1 cm =10 mm
Length of firs line segment =
Length of two line segments together=500+300=800 mm=
Hence, the length of two line segments together=800 mm=80 cm

Answer:
vertex(-3,27)
Step-by-step explanation:
f(x)= x^2+ 6x + 36 ( a=1,b=6,c=36)
V(h,k)
h=-b/2a=-6/2=-3
k=f(-3)=3²+6(-3)+36
f(-3)=9-18+36=27
vertex(-3,27)
Answer:
B and C
Step-by-step explanation:
The really tough one to get rid of is A. She's right in her method and it sounds like A should be a deal breaker. Suppose however, you make y = 1/x. Now the equation is linear.
y + 3 = 3y Subtract y from both sides
3 = 3y - y
3 = 2y Now divide this by by 2
3/2 = y
But they are not the same answer!! You've gotten rid of one problem only to create another. Well yes. I never said it was easy getting rid of A. But remember y = 1/x, so x will equal 1 / y.
x = 1/y = 1//3/2 = 2/3
Now they agree.
That's kind of sneaky you might say. That's right it is. But its not wrong. A is not part of the answer.
B is certainly right.
C is correct as well, That's the way the equation is ultimately solved.
D is nonsense. You can do all sorts of things with the letters in equations
