Answer:
120
Step-by-step explanation:
Make a chart:
Lines: 0 1 2 3 4 5 6
Closed regions: 0 0 0 1 3 6 10
Find the number of numbers using the formula:
[tex]\frac{first term + last term}{2}[/tex] x 14 = [tex]\frac{2 + 15}{2}[/tex] x 14
= 8.5 x 14
= 119
119 + 1 = 120
(add 1 because we didn't count the first line in the formula)
I hope this helps :)
The total number of closed regions is 120.
Given that,
Seventeen lines are drawn in a plane, with no three concurrent and no two parallel, dividing the plane into closed regions (bounded on all sides) and open regions.
Used the formula to calculate the number of closed regions with n sides is,
Number of sides = (n - 1) (n - 2) / 2
Here, n = 17
Hence, The number of closed regions is,
Number of sides = (n - 1) (n - 2) / 2
Number of sides = (17 - 1) (17 - 2) / 2
Number of sides = 16 × 15 / 2
Number of sides = 120

[tex] \{y| - 3 \leqslant y \leqslant 4 \}[/tex]sam currently has $150 in a savings account and is saving 10$ per week. write an equation
Answer:
$850
Step-by-step explanation:
you multiply 7 x 100 because there are 7 days in 1 week. That equals 700 plus 150 equals 850
Sam currently has $150 in a savings account and is saving 10$ per week. equation y=150+10x represents the situation.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given, sam currently has $150 in a savings account and is saving $10 per week.
The total amount of savings in dollars is represented by y.
x represents the number of weeks
The equation y=150+10x.
y equal to one hundred and fifty plus ten times of x.
Hence, Sam currently has $150 in a savings account and is saving 10$ per week. Equation y=150+10x represents the situation.

Juan graphed a line with a slope of −23 .
How does Juan count the slope from any point on the graph?
From any point on the graph, he counts down 2 then right 3 to end up on the line again.
From any point on the graph, he counts up 2 then right 3 to end up on the line again.
From any point on the graph, he counts down 2 then left 3 to end up on the line again.
Answer:
The answer is: From any point on the graph, he counts down 2 then right 3 to end up on the line again.
Step-by-step explanation:
To count the slope of the graph from any point on the graph; He counts down 2 then right 3 to end up on the line again.
The slope of a linear graph refers to the change behaviour of its dependent variable (usually y-axis) with respect to its Independent variable (usually x-axis).
In essence;
slope, m = (y2-y1)/(x2-x1)
Consequently, From any point on the graph, he counts down 2 then right 3 to end up on the line again.

What is the value of T in this exterior angle
Answer:
t =30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles.
t + (2t-28) = t+32
Combine like terms
3t -28 = t+32
Subtract t from each side
3t -28-t = t+32-t
2t -28 = 32
Add 28 to each side
2t-28+28 = 32+28
2t = 60
Divide by 2
2t/2 = 60/2
t =30

Which is the better buy?
A 450 g box of cereal for $4.69 or a 600 g box of cereal for $6.49?
Please show ALL of your work.
hint: convert each to a unit rate using "cost / gram", then compare each to see which is cheaper.
Answer: The first box (the 450 g box for $4.69)
===========================================================
Explanation:
To get the unit cost, we'll divide each price by the weight
The first box has a unit cost of (4.69)/450 = 0.010422 approximately which rounds to 0.01; so this unit cost is approximately $0.01 per gram or 1 cent per gram.
For the second box, its unit cost is (6.49)/600 = 0.0108167 approximately. When we round to the nearest cent, we get the same unit cost as before. Without rounding, we see that the first box has a slightly lower unit cost. Therefore box 1 is the better buy.
