(x,y)
we are given x=2
find what y is when x=2
subsitute 2 for x
y=2x+5
y=2(2)+5
y=4+5
y=9
so the blank is 9
when numbers are in parenthesis the first number is x the second is y
(x,y)
sine they give you (2, blank)
2 = x so replace x in the equation with 2
so y=2x+5 becomes y=2(2)+5
so y = 2*2+5 = 9
y=9
so it should be (2,9)

Frank borrowed $400 from his neighbor. He made 3 payments of $65 each and another payment of $95. How much does Frank still owe?
Answers
Frank borrowed $400. He made 3 payments of $65 and an additional payment of $95.
Let's start by setting up our equation.
400 = 3(65) + 95
Multiply 3 by 65.
400 = 195 + 95
Combine like-terms.
400 = 290
Subtract 290 from both sides.
110
Frank still owes $110 to pay.
I hope this helps!
Convert 28.7251° to degrees, minutes, and seconds. Round to the nearest second.
Answers
28.7251 =
28 degrees
then take the decimal and multiply by 60 to get the minutes
so 0.7251 *60 = 43.506, use the whole number (43)
so now you have 28 degrees, 43 minutes
now take the remaining decimal ( 0.506) and multiply by 60
0.506*60= 30.36
when you have a decimal left over for the seconds, keep that as is.
so you now have 28 degrees, 43 minutes and 30.36 seconds
use ' for minutes and " for seconds
28 degrees 43' 30.36"
Final answer:
To convert 28.7251 degrees to degrees, minutes, and seconds, take the whole number of degrees (28) and multiply the decimals (.7251) by 60 to get the minutes (43). Then multiply the remaining decimal of the minutes (.506) by 60 to get the seconds (30), resulting in 28 degrees, 43 minutes, and 30 seconds (28° 43' 30").
Explanation:
To convert 28.7251 degrees to degrees, minutes, and seconds, you follow a multi-step process which involves converting the decimal part of the degrees into minutes and then into seconds. First, identify the whole number of degrees, which is 28 in this case.
To convert the decimal part (.7251) to minutes, multiply by 60. Using the operation provided in the reference, with 0.7251 × 60, you get 43.506 minutes. The whole number part, 43, is the minutes.
To convert the remaining decimal part of minutes (.506) into seconds, again multiply by 60. This gives you (.506 imes 60) 30.36 seconds, which when rounded to the nearest second is 30 seconds.
Therefore, 28.7251 degrees is equal to 28 degrees, 43 minutes and 30 seconds (28° 43' 30").

A)The supply decreased.
B) The supply stayed the same.
C) The supply increased.
D) The supply outweighed demand.
Answers
Correct answer: B
Answer:
Option B is correct.
Step-by-step explanation:
We have been given x-axis representing quantity
And y-axis representing price
S1 and S2 are supply
So, these two supply have parallel lines which means they will never intersect they will remain same throughout the domain.
Therefore, the supply stayed the same.
Option B is correct.

Julio has started his very own floral business. He sells centerpieces for $19.50 each. His fixed costs are $500 per month, and each centerpiece cost $8 to produce. What is your break-even point? a. Julio must sell approximately 18 centerpieces to break even. b. Julio must sell approximately 23 centerpieces to break even. c. Julio must sell approximately 44 centerpieces to break even. d. Julio must sell approximately 55 centerpieces to break even.
Answers
500= (19.50-8.00)x
500 = 11.50x
x=500/11.50=43.48
so he needs to sell approximately 44 centerpieces to break even
Solve for x
19.50x - 8x=500
11.5x=500
X=500/11.5
X=43.48
The answer is
c. Julio must sell approximately 44 centerpieces to break even.
What is the intersection of this sphere with the yz-plane? find an equation of the sphere with center (−3, 2, 9) and radius 6?
Answers
[tex] (x-a)^{2} + (y-b)^{2} + (z-c)^{2} = r^{2} [/tex],
so the equation of the sphere with center (-3, 2, 9) and radius 6 is :
[tex](x-(-3))^{2} + (y-2)^{2} + (z-9)^{2} = 6^{2} [/tex]
[tex](x+3)^{2} + (y-2)^{2} + (z-9)^{2} = 36[/tex]
The yz plane is the set of all points (0, y, z), that is x is always 0.
For x=0, the plane
[tex](x+3)^{2} + (y-2)^{2} + (z-9)^{2} = 36[/tex]
becomes
[tex](0+3)^{2} + (y-2)^{2} + (z-9)^{2} = 36[/tex]
[tex](y-2)^{2} + (z-9)^{2}=36-9=25= 5^{2} [/tex]
[tex](y-2)^{2} + (z-9)^{2}=5^{2} [/tex]
This is the circle with center (y, z)=(2, 9) and radius 5.
The equation of the sphere with center (-3, 2, 9) and radius 6 is (x + 3)² + (y - 2)² + (z - 9)² = 6². The intersection of this sphere with the yz-plane is described by the equation (y - 2)² + (z - 9)² = 27.
Explanation:The equation of a sphere with center (-3, 2, 9) and radius 6 is given by:
(x + 3)² + (y - 2)²+ (z - 9)² = 6²
To find the intersection of this sphere with the yz-plane, we need to set x = 0 in the equation:
(0 + 3)² + (y - 2)² + (z - 9)² = 6²
Simplifying this equation gives:
(y - 2)² + (z - 9)² = 27
So, the intersection of the sphere with the yz-plane is described by the equation (y - 2)² + (z - 9)² = 27.

Answers
x² = 5(5+12) = 5 * 17 = 85

Answer:
9.2
Step-by-step explanation:
We are given that a figure in which a tangent and a secant to the circle.
We have to find the value of x.
Length of tangent segment=x
Length of secant segment=12 +5=17 units
Length of external segment=5 units
We know that secant-tangent theorem
It states that product of length of secant segment and its external segment is equal to square of length of tangent segment.
[tex]x^2=17\times 5=85 [/tex]
[tex]x=\sqrt{85}=9.2 units[/tex]

An airplane pilot over the Pacific sights an atoll at an angle of depression of 5. At this time, the horizontal distance from the airplane to the atoll is 4629 meters. What is the height of the plane to the nearest meter?
A. 403 m
B. 405 m
C. 4611 m
D. 4647 m
Answers
tan(5) = x/4629
4629tan(5) = 404.9
Round up
x=405 m
Rounded to the nearest meter, the height of the plane is approximately 405 meters.
So, the correct answer is B. 405 m.
To find the height of the plane, we can use trigonometry, specifically the tangent function.
Let's denote the height of the plane as h (in meters).
From the information given, we know that the angle of depression from the airplane to the atoll is 5 degrees, and the horizontal distance from the airplane to the atoll is 4629 meters.
Using the tangent function, we have:
tan(angle of depression) = height / horizontal distance
tan(5 degrees) = h / 4629
To find the value of h, we can rearrange the equation:
h = 4629 * tan(5 degrees)
Now, let's calculate the height of the plane:
h ≈ 4629 * 0.0874886635 ≈ 404.773 meters
Rounded to the nearest meter, the height of the plane is approximately 405 meters.
So, the correct answer is B. 405 m.

The roof of a house is being reconstructed to accommodate heavy snows. the current 32 foot roofline makes an 18.2° angle with the horizontal. the owner has decided to construct the new roof so that it makes a 50° with the horizontal as shown below. what will be the length of the new roofline?
Answers
To find the length of the new roofline, we can use the tangent function. The length is approximately 26.9 feet.
Explanation:To find the length of the new roofline, we can use the trigonometric function tangent. Let's call the length of the new roofline 'x'. The tangent of an angle is equal to the opposite side divided by the adjacent side. In this case, the opposite side is the height of the roofline, which is 32 feet, and the adjacent side is the horizontal distance, which is 'x' feet. So, we can set up the equation:
tan(50°) = 32/x
To solve for 'x', we can multiply both sides of the equation by 'x' and then divide both sides by tan(50°). This gives us:
x = 32/tan(50°)
Using a calculator, we can find that tan(50°) ≈ 1.1917. So, substituting this value into the equation, we get:
x ≈ 32/1.1917
By calculating this, we find that the length of the new roofline is approximately 26.9 feet.
