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 system of equations is shown below.
y=-2x + 6
6x + 3y = 18
What is the solution to the system of equations?
(Show work)
Answer:
Step-by-step explanation:
First, we need to look at the simpler equation. We see that the top equation is the simpler one.
y=-2x + 6
Now we plug that equation with the other one.
6x + 3(-2x + 6) = 18
6x -6x + 18 = 18
18 = 18
Since we see that 18 = 18. We know that this equation is a true equation. We can plug the y-variable in first and it will still be a true statement.
y=-2x+5 how do you solve?
Answer:
here are the coordinates :
(0,5) and (1,3)

for solving, eqn (i) - eqn (ii)
7x + 5y = 43
5x + 5y = 5

Answer:
BC = 20.7
Explanation:
Formula used: a² = b² + c² - 2bc*cos(A)Using the formula: BC² = 15² + 13² - 2*15*13*cos(95)
BC² = 427.991
BC = √427.991

Which inequality can be used to determine the amount of money the family still needs to save? 2764 x > 5000 2764 x Greater-than-or-equal-to 5000 2764 x Less-than-or-equal-to 5000 5000 x > 2764.
The amount of money the family still needs to save is $2236.
Linear systemIt is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
Their vacation savings account currently has a balance of $2,764.
The family would like to have at least $5,000.
To findThe amount of money the family still needs to save.
How to find the amount of money the family still needs to save?Forming the equation, we get
Let x be the amount needed to save. then
x + 2764 ≥ 5000
On simplifying, we get
x + 2764 ≥ 5000
x ≥ 5000 - 2764
x ≥ 2236
Thus, the amount of money the family still needs to save is $2236.

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:

A 4. 9-mm-wide swimming pool is filled to the top. The bottom of the pool becomes completely shaded in the afternoon when the sun is 20 ∘∘ above the horizon.
The depth of the swimming pool that is filled to the top is; 4 m
Snell's Law
I have attached a schematic diagram showing this question.
The correct width of the pool is 4 meters. Thus; w = 4 m
Incident Angle; θ₁ = 20°
A right angle is 90° and so the angle θ₂ is calculated from;
θ₂ = 90° - θ₁
θ₂ = 90° - 20°
θ₂ = 70°
We can use snell's law formula to find θ₃.
Thus;
n₁sinθ₂ = n₂sinθ₃
where;
n₁ is refractive index of air = 1
n₂ is refractive index of water = 1.33
Thus;
1*sin 70 = 1.33*sin θ₃
sin θ₃ = (sin 70)/1.33
Solving this gives;
θ₃ = 44.95°
By usage of trigonometric ratios we can find the depth of the pool using;
w/d = tan θ₃
Thus;
d = w/(tan θ₃)
d = 4/(tan 44.95)
d ≈ 4 m

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.
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.
