Which expression is equivalent to 9x + 4y + 2x - y²?​

Answer:

Step-by-step explanation:

If you're solving for m:

3.18 + 2m = 12.7

-3.18            -3.18

Therefore making the new equation: 2m = 9.52

Divide- [tex]\frac{2m}{2\\} =\frac{9.52}{2}[/tex]

m = 4.76

A claim is classified as science if there are experiments, or statistical tests, that prove the claim. In the cats experiment, there is evidence, hence it is science.

A claim is classified as biased when no experiments are made, the observations are made with the "eye test". One example is watching a NFL game and saying that the team that gets the most passing yards generally wins, without making statistical tests to verify this.

For this problem, the ad for the tire is based on bias, as there were no experiments, just the eye test.

The rate r with the given distance is 65 miles/hour.

Given that, the formula d=2r can be used to find the distance d travelled after 2 hours at rate r.

Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, the distance may refer to a physical length or an estimation based on other criteria.

Now, the given formula is d=2r.

So, the formula for r is r=d/2

Distance = 130 miles

Then, the rate r = 130/2 = 65 miles/hour

Therefore, the rate r with the given distance is 65 miles/hour.

The area of the running track to the nearest tenth of a yard is 1456 yards

The length of the field is 100 yards with a width of 40 yards.

Notice that the two semicircles on both ends form a circle with diameter 40 yards. Since it's diameter is 40, then it's radius is 20. We can get the length of the rectangle by subtracting two 20 from 100 or subtracting it's diameter to the entire length 100:

= 100-20-20

=100-40

=60

Since we formed a rectangle with two semicircles on both ends, we have the length of the rectangle 60 yards and the width 40 yards.

We first get the circumference of the circle.

C=πd

=(3.14)(40)=125.6

Then we get the measure of the two lengths of the rectangle which is 60

60+60=120

We multiply 145.6 by 10 and we get 1456

Therefore, the area of the running track to the nearest tenth of a yard is 1456 yards.

Step-by-step explanation:

Determine if 36 is a cube root

(a-b)•(a^2+ab+b^2) =

           a^3+a^2b+ab^2-ba^2-b^2a-b^3 =

           a^3+(a^2b-ba^2)+(ab^2-b^2a)-b^3 =

           a^3+0+0-b^3 =

           a^3-b^3

→ Using this checker, we can see that 36 is not a cube root because it cannot be factored as the difference between two perfect cubes.

Solve

v^3 - 36 = 0

v^3 = 36

1. The given equation is in the slope intercept form.

2. The standard form is x ₊ 2y = ₋6

3. The given equation is in the point slope form.

4. The standard form is 2x ₋ 3y = ₋3

Given,

the equation is y = ₋1/2x ₋ 3

the above equation is in the form of slope intercept form i.e,

y = mx ₊ c

to convert it into standard form i.e, ax ₊ by = c

therefore, 2y = ₋x ₋ 6

x ₊ 2y = ₋6

2. the equation is y ₋ 7 = 2/3 (x ₋ 9)

the above equation is in the form of point slope form.

i.e, y ₋ y₁ = m(x ₋ x₁)

therefore, to convert it into standard form i.e, ax ₊ by =c

y ₋ 7 = 2/3 (x ₋ 9)

3(y ₋ 7) = 2(x ₋ 9)

3y ₋ 21 = 2x ₋ 18

3y ₋ 2x = ₋18 ₊ 21

In mathematics, an inverse function is one that "reverses" another function. The inverse of y = 2x + 8 is f⁻¹(x) = x/2 − 4.

The inverse function of a function f in mathematics exists a function that reverses the operation of f. If the inverse of f exists, it is shown by the f⁻¹. The inverse of f exists if and only if f exists bijective.

An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f ⁻¹.

Let the function be y = 2x + 8

Interchange the variables.

x = 2y + 8

Solving for y

y = x/2 − 4

Replace y with f⁻¹(x), we get

f⁻¹(x) = x/2−4

Verify if f⁻¹(x) = x/2−4 is the inverse of f(x) = 2x+8.

The inverse of y = 2x+8 is f⁻¹(x) = x/2−4.

The equation to describe the linear relationship:

The amount Jaycee has in her vacation savings = Amount Jaycee has saved + Additional amount jaycee saved per week(Number of weeks Jaycee saved)

y = 75 + 15(x)

y = 75 + 15x

For instance, if jaycee has saved for 5 weeks, the

amount Jaycee has in her vacation savings is

We need to know about translation, reflection and rotation to solve the problem. (1) We translate a triangle with respect to a horizontal and vertical direction. (2) We rotate a traingle about a given angle. (3) We refelct a triangle about a line of reflection which can be axis or vector.

(1) Translation of a triangle means changing it's position without changing the shape or size of the triangle. We translate a triangle with respect to a horizontal and vertical direction. We get the new triangle by adding the horizontal translation value to the x-coordinate and the vertical translation value to the y-coordinate.

(2) Rotation of a triangle is turning the triangle by an angle around a center point. When a triangle is rotated by 90° clockwise then (x,y) becomes (y,-x), when rotated by 90° anticlockwise (x,y) becomes (-y,x), when rotated by 180° clockwise or anticlockwise (x,y) becomes (-x,-y).

(3)Reflection of a triangle is finding a mirror like image of the triangle about  a line of reflection. The line of reflection may be either of the axes, a vector. To find the image we have to find the coordinates of the triangle that are of same distance from the line of reflection on the opposite side like they are from the original triangle.

Therefore we learnt about translation, reflection and rotation and saw that (1) Translation needs a horizontal and vertical direction for translating, (2) Rotation needs an angle of rotation and a center point and (3) Reflection needs a line of reflection.
