y=-2/3x+3 in standard form
Answer:
-2/3x + 3
Step-by-step explanation:
Standard form is just ax^2 + bx + c
In this equation, there is no ax^2. So we have 2/3x + 3.
We don't have to make any changes because the equation is already in standard form.

A. What is the total amount of fabric needed to sew both the pants and the shirt? Show your work and explain your answer.
252 is the answer
total amount=the whole amount
total amount =amount of pants+amount of shirts

Answer:
Below!
Step-by-step explanation:
We know that:
All sides of a rhombus are the same. This tells us that a rhombus can be divided in two triangles. Both the triangles are isosceles triangle.This also tells us that x must equal 23° because the base angles of an isosceles triangle are always the same. A rhombus has 4 right angles in its center.Triangle = 180°Solution:
y + 90 + 23 = 180=> y + 113 = 180=> y = 180 - 113=> y = 67°Hence, the value of x and y are 23° and 67° respectively.

The coordinates of the vertices of ΔABC are A(−5, 1), B(−5, −1), and C(−1, −1). Find the side lengths and the angle measures.
AB = 4, BC = 2, AC ≈ 4.24
m∠B = 90°, m∠A ≈ 63°, m∠C ≈ 27°
AB = 2, BC = 4, AC ≈ 4.24
m∠B = 90°, m∠A ≈ 27°, m∠C ≈ 63°
AB = 2, BC = 4, AC ≈ 4.47
m∠B = 90°, m∠A ≈ 63°, m∠C ≈ 27°
AB = 4, BC = 2, AC ≈ 4.47
m∠B = 90°, m∠A ≈ 27°, m∠C ≈ 63°
The given coordinates of the vertices of the triangle ΔABC, which are: A(-5, -1), B(-5, -1), and C(-1, -1), gives the side lengths and the angle measures found using Pythagorean theorem, and the law of cosines as follows:
AB = 2, BC = 4, AC ≈ 4.47
m∠B = 90°, m∠A ≈ 63°, m∠C ≈ 27°
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the sum of the squares of the legs, is equal to the square of the length of the hypotenuse side.
The vertices of the triangle are; A(-5, 1), B(-5, -1), and C(-1, -1)
The length, l, of a line having points (x₁, y₁) and (x₂, y₂) can be found using Pythagorean theorem as follows;
[tex]l = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}[/tex]
The length of AB = √((-5 - (-5))² + (-1 - 1)²) = 2
Length of BC = √((-1 - (-5))² + (-1 - (-1))²) = 4
Length of AC = √((-1 - (-5))² + (-1 - 1)²) ≈ 4.47
The interior angles can be found using the law of cosines as follows:
a² = b² + c² - 2·b·c·cos(A)
Which gives: 2·b·c·cos(A) = b² + c² - a²
[tex]\angle A = arccos\left(\dfrac{b^2 + c^2 - a^2}{2\cdot b \cdot c} \right)[/tex]
Where:
a, b, and c are the side lengths of the triangle, and ∠A is the angle opposite side a.
Taking AB = c, BC = a, AC = b, gives:
[tex]\angle A = arccos\left(\dfrac{4.47^2 + 2^2 - 4^2}{2\times 4.47 \times 2} \right) \approx 63^{\circ}[/tex]
Similarly, we have:
[tex]\angle B = arccos\left(\dfrac{4^2 + 2^2 - 4.47^2}{2\times 4\times 2} \right) \approx 90^{\circ}[/tex]
Which by the angle sum property of a triangle gives: ∠C = 180° - 90° - 63° = 27°
The option that gives the side lengths and the angle measure is therefore:
AB = 2, BC = 4, AC = 4.47, m∠B = 90°, m∠A = 63°, m∠C = 27°Learn more about the law of cosines here:

Which functions represent exponential growth? y = f(x) y = h(x) y = g(x) y = k(x).
All are the exponential function.
ExponentExponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. c is the base and x is the power.
Which functions represent exponential growth?1. y = f(x) is a exponential function.
Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.
2. y = h(x) is a exponential function.
Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.
3. y = g(x) is a exponential function.
Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.
4. y = k(x) is a exponential function.
Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.
Thus, all are the exponential function.
