Answer:
(a) The blue line ... solution ... (-6, -2)..
Step-by-step explanation:
The second equation describes a line with negative slope and a y-intercept of -4. This is clearly the red line on the graph.
The blue line represents the equation 2x -3y = -6.
The point of intersection of the two lines is (-6, -2), so that is the solution to the system of equations. This, by itself, is sufficient for you to choose the correct answer.
Step-by-step explanation:
<h2>a).</h2>
To find the area of the circle we must first find the radius using the formula
radius = diameter / 2
From the question
diameter = 21 ft
The radius is
21/2 = 10.5 ft
Area of a circle = πr²
where r is the radius
Area = π(10.5)²
= 110.25π
<h3>= 346.36 cm²</h3>
<h2>b).</h2>
Circumference of a circle = πd
where d is the diameter
Circumference = π(21)
<h3>= 65.97cm</h3>
Hope this helps you
Answer:
$95
Step-by-step explanation:
We are told that Carmen makes a monthly payment of no more than 200 dollars. We then see her going above the 200 dollars so we look to the tens and ones place. We see that we now have 25, 45, and 35 dollars. Add them up and you get 105 dollars. 200-105=95 so your awnser is $95.

Answer:
D. 119
Step-by-step explanation:
To find the common difference, we take the second term and subtract the first term
2-(-7) = 9
We check by taking the third term and subtracting the second
11-2 = 9
The common difference is 9
The formula for an arithmetic sequence is
an = a1 +d(n-1)
where a1 is the first term, d is the common difference and n is the number of the term in the sequence
a1=-7, d=9 and we are looking for the 15th term so n=15
a15 = -7 +9(15-1)
a15 = -7+9(14)
=-7 +126
= 119
