hope this helps
Answer:
B
X= 7.5
Y= -5
Step-by-step explanation:
In systems of equations, the goal is to add both of the equations together so it cancels one of the variables and you solve for that variable. Before you add they together, you multiply one of the equations by a negative number so when you add them together one of the numbers with x or y cancel.
I will upload a picture showing my work.
Answer:
The answer to your question is: third option, it's a parabola
Step-by-step explanation:
f(x) = (x + 4)²
f(x) = x² + 4
f(x) = (x - 4)² I think this is the right answer, because when get the vertex, the signs are changed, if the -4 is negative, it means that the graph must be located in +4.
f(x) = x² - 4
Oh, this is easy. For any prism, you find the surface area by finding the are of all the sides. I will post all surface area formulas here, for reference
Cube:
Surface area = 6 × a2
Right circular cylinder:
Surface area = 2 × pi × r2 + 2 × pi × r × h
pi = 3.14
h is the height
r is the radius
Rectangular prism:
Surface area = 2 × l × w + 2 × l × h + 2 × w × h
l is the length
w is the width
h is the height
Sphere:
Surface area = 4 × pi × r2
pi = 3.14
r is the radius
Right circular cone:
Surface area = pi × r2 + pi × r ×( √(h2 + r2))
pi = 3.14
r is the radius
h is the height
l is the slant height
Right square pyramid:
Surface area = s2 + 2 × s × l
s is the length of the base
h is the height
l is the slant height
