Answer:
B.) The graph of m(x) is wider.
Both graphs open upward.
Both have the axis of symmetry x = 0.
The vertex of m(x) is (0, 4); the vertex of n(x) is (0, 0).
Step-by-step explanation:
When the coefficient before x² is greater than 1, the curve of the graph is narrower. When the coefficient is less than 1, the curve of the graph is wider.
When the coefficient in front of x² is positive, the graph opens upwards. When the coefficient is negative, the graph opens downwards.
The axis of symmetry is the "x" value which divides the curve into two equal sections. Their axis of symmetry are both x = 0 because their vertexes (the lowest point of the curve) are both at x = 0.
The vertex can be found by plugging x = 0 into both of the equations and then solving. The resulting value is the "y" position of the vertex.
m(0) = 0.7(0)² + 4 n(0) = (0)²
m(0) = 0 + 4 n(0) = 0
m(0) = 4
Therefore, the vertexes are m(x) = (0,4) and n(x) = (0,0).
Answer:
5y = x
Step-by-step explanation:
15 miles = 3 hours
Divide by 3 on both sides to find how many miles he/she can run in 1 hour.
15 miles = 3 hours ⇒ 5 miles = 1 hour
Therefore, the equation is just 5y = x.

Answer with Step-by-step explanation:
Since we have given that
Some students in my class use e-mail.
It is a type of 'E' statements.
Its negation should be No students in my class use e-mail.
Because if we use "Some students in my class do not use e-mail”.
It also implies some students in my class still use e-mail.
But negation contains only opposite of given statement.
So, Some students in my class do not use e-mail” is not true.
Answer:
Step-by-step explanation:
4) You just have to find the lcm of the denominators
a) lcm(4,3,6)=4*3=12
b) I don't know the name of the property but it is :
"We can multiply the two members of an equality by the same non-zero number, we obtain an equality. "
