Answer:
Yes, y is a function of x.
Explanation:
Based on the information given, the equation will be y = 9.6x.
From the equation given, it was stated that the amount Lin's sister earns at her part-time job is proportional to the number of hours she works and that she earns $9.60 per hour.
Therefore, writing the equation in the form y=kx to describe this situation will be:
y = (9.6 × x)
y = 9.6x

Step-by-step explanation:
What is the sale price of a rowboat originally priced at $90? If it's marked down 70%
Answer:
Correct answer:
$20.40
Step-by-step explanation:
20% off means that the new price of the skirt will be 80% of the original price:
$30(100% – 20%) = $30(80%)
Converting the percent to a decimal gives:
$30(0.8) = $24.00
There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:
$24(100% – 15%) = $24(85%)
Again converting the percent to a decimal gives:
$24(0.85) = $20.40
solve this system of equations by graphing y=5/3x+3 y=1/3x-3
The solution to the system of equation is x = 9 /2 and y = - 3 / 2
Simultaneous equationy = 5 / 3 x + 3
y = 1 / 3 x - 3
Therefore, let subtract equation(i) from equation (ii) to eliminate y
5 / 3 x - 1 / 3 x = 3 + 3
5x - x / 3 = 6
4x / 3 = 6
cross multiply
18 = 4x
x = 18 / 4
x = 9 / 2
Therefore,
y = 1 / 3(9 / 2) - 3
y = 9 / 6 - 3
y = 9 - 18 / 6
y = - 9 / 6
y = - 3 / 2

If the length of a rectangle is 4x² - x +2, and the width of the rectangle
is 5x - 3, what is the perimeter of the rectangle expressed as a
polynomial?
8x^2-12x+10
8x^2+8x-2
8x^2-12x+10
8x^2-8x+2
Answer:
8x² + 8x - 2Step-by-step explanation:
We know that:
Perimeter of a rectangle = Sum of all its sidesLength of rectangle = 4x² - x + 2Width of rectangle = 5x - 3To find the perimeter, we need to use the equation "Perimeter of a rectangle = Sum of all its sides".
Solution:
Perimeter of a rectangle = Sum of all its sides=> 2[{4x² - x + 2} + {5x - 3}] = Perimeter=> 2[4x² - x + 2 + 5x - 3] = Perimeter=> 2[4x² + {-x + 5x} + {2 - 3}]=> 2[4x² + 4x - 1]=> 8x² + 8x - 2Hence, the perimeter of the rectangle is 8x² + 8x - 2.

1/7 of all students achieved great success in the written exercise in mathematics. 3/7 very good success. 2/7 good success, while 4 students achieved sufficient success. How many students did the writing exercise?(fractions)
Answer:
x = 28
Step-by-step explanation:
Let the total number of students = x
x/7 + 3x/7 + 2x/7 + 4 = x If that is all there is. If it isn't the problem can't be done. Combine like terms.
x(1 + 3 + 2)/7 + 4 = x
x (6/7) + 4 = x Subtract 6x/7 from both sides
4 = x - 6x/7
4 = 7x/7 - 6x/7 Combine
4 = 1/7x Multiply both sides by 7
4*7 = 7x / 7
x = 28

A triangle is a polygon with three sides and three angles.
There are different types of triangles such as the isosceles triangle, equilateral triangle, scalene triangle, right-angled triangle.
What is the law of cosine?The law of cosines states that for a triangle with sides a, b, and c and the corresponding angles opposite to the sides which are A, B, and C. Then:
a² = b² + c² – 2bccos(A)
Let ML = a = 5.74, LN = b = 4, MN = c = 7.
∠N is opposite to side ML. Let ∠N be A,
a² = b² + c² – 2bccos(A)
2bc* cos(A) = b² + c² – a²
Substituting:
2(4)(7) × cos(A)= 4² + 7² - 5.74²
56cos(A) = 32.0524
cos(A) = 0.5723
A = cos⁻¹(0.5723)
A = 55⁰
A = ∠N = 55⁰
Hence, the measure of the angle N is 55 degrees.

Answer:
x = 13.5
y = 7
(13.5,7)
what the solution means is that (13.5,7) would be the point at which the two lines, x+y=20.5 and x-y=6.5, would intersect
Step-by-step explanation:
x + y = 20.5
x - y = 6.5
if we add the two equations we get:
2x = 27
x = 13.5
y = 20.5 - 13.5
y = 7
solution as an ordered pair:
(13.5,7)
What the solution means is that (13.5,7) would be the point at which the two lines, x+y=20.5 and x-y=6.5, would intersect
