Answer:
2 , 10 , and 15 in order of missing spaces, up to down
Step-by-step explanation:
You find the ration 8/20 and find out if the ration is simplifiable and turn it to 2/5 which you multiply the rest of the answers too. Hope this answers your question :)
Answer:
The inequality x>2 matches the graph.
Step-by-step explanation:
From the graph, it is clear that the shaded graph is heading towards the +ve infinity from the x > 2.
If the inequality includes < or >, we graph the equation as a dotted line.
From the graph, the dotted line indicates that x=2 is not included in the solution of the inequality.
so the interval of the domain of the inequality is: (2, ∞)
Therefore, the inequality x>2 matches the graph.
Answer:
Los números enteros son los naturales, sus opuestos (negativos) y el cero. El conjunto de los números enteros se representa mediante una Z, Z= {0,1,-1,2,-2,3,-3,4,-4...}. Se cumple entonces que todo número natural es entero.
Answer:
numbers that cannot be reduced when squared, ex: 1,3,5,
Step-by-step explanation:
These numbers factors are themselves and 1, to find if it is a prime number you can try to find the factors and if it is just itself and 1, then it is a prime number
Answer:
y = 3 (x+8)^2 -7
Step-by-step explanation:
The vertex form of the equation is
y = a(x-h)^2 +k
where (h,k) is the vertex
y = a (x- -8)^2 + -7
y = a (x+8)^2 -7
Now substitute the point into the equation to determine a
-4 = a (-7+8)^2 -7
-4 = a (1^2) -7
-4 = a -7
Add 7 to each side
-4+7 = a-7+7
3 =a
y = 3 (x+8)^2 -7
