Answer:
The value of c that completes the square 
is 1
Step-by-step explanation:
We need to find the value of c that completes the square
The formula used will be: 
In the question given the value c can be found by breaking the middle term. we are given 2x while the general formula is 2ab for middle term so,
2(x)(1) = 2x
so, c= 1
Solving:
So, the value of c that completes the square is 1
Answer:
3 and 4 are complementary because they both add up to 90
Step-by-step explanation:
Answer:
Tamara's example is in fact an example that represents a linear functional relationship.
- This is because the cost of baby-sitting is linearly related to the amount of hours the nany spend with the child: the more hours the nany spends with the child, the higher the cost of baby-sitting, and this relation is constant: for every extra hour the cost increases at a constant rate of $6.5.
- If we want to represent the total cost of baby-sitting in a graph, taking the variable "y" as the total cost of baby-sitting and the variable "x" as the amount of hours the nany remains with the baby, y=5+6.5x (see the graph attached).
- The relation is linear because the cost increases proportionally with the amount of hours ($6.5 per hour).
- See table attached, were you can see the increses in total cost of baby sitting (y) when the amount of hours (x) increases.
Answer:
<u><em>2</em></u>
Step-by-step explanation:
There are 6 sides:
3 by 4 = 3*4 = 12, no
3 by 3 = 3*3 = 9, no
5 by 3 = 5*3 = 15, no
Triangles:
Half of 3 by 4 = 1/2 * 3* 4 = 1/2 * 12 = 6, yes
The other triangle is the same, so 2
Answer:
90 games
Step-by-step explanation:
Of the 120 games the football team played, they won 75% of them.
Remember that in mathematics, "of" almost always means to multiply. Here, that means we must multiply 75% by 120:
75% * 120
Remember also that % just means divided by 100, so 75% = 75 / 100. So:
75% * 120 = (75/100) * 120 = 9000/100 = 90 games
