Which expression is equivalent to the expression below?

Answer:

8x+ 6 is the translated mathematical expression.

Step-by-step explanation:

We are given the following English expression which are to translate into a mathematical expression:

'The sum of 6 and the product of 8 and x” into a mathematical expression'

Translating it in small chunks:

1. the sum of 6 ---> +6

2. product of 8 and x ---> 8x

Therefore, combining these we get the mathematical expression 8x + 6

For this case we must rewrite the given expression mathematically.

The sum of 6 and something else is written as:

[tex]6+[/tex]

The product of 8 and x is written as:

[tex]8x[/tex]

Finally, the expression is given by:

[tex]6 + 8x[/tex]

Answer:

The expression is given by:

[tex]6 + 8x[/tex]

Final answer:

The equation of the quadratic graph with a focus of (3, 6) and a directrix of y=4 is (x-3)² = 4(y-5).

Explanation:

To find the equation of a quadratic graph with a focus of (3, 6) and a directrix of y=4, you'll need to use the definition of a parabola. A parabola is the set of all points that are equidistant from a single point, called the focus, and a line, known as the directrix. In this case, since the directrix is horizontal (parallel to the x-axis) and the focus has a y-coordinate greater than the directrix, the parabola opens upwards.

The vertex of the parabola is equidistant from the focus and directrix, so its y-coordinate is halfway between the focus's y-coordinate and the directrix's y-value, which is 5. Because the x-coordinate of the focus is 3, the vertex is at (3, 5). The equation of a parabola in vertex form is (x-h)² = 4p(y-k), where (h,k) is the vertex and 4p is the distance between the vertex and the focus or the vertex and the directrix.

In this problem, the distance p is 1 (since the y-coordinates of the vertex and focus differ by 1). Thus, the equation of the parabola is (x-3)² = 4(y-5). This is the standard quadratic form for a parabola opening upwards with vertex at (3, 5) and focus at (3, 6).

Answer:

3/16

Step-by-step explanation:

The nth term of a geometric series is:

an = a₁ (r)^(n - 1)

Given a₁ = 6, r = 1/2, and n = 6:

a₆ = 6 (1/2)^(6 - 1)

a₆ = 3/16

Answer:

12

Step-by-step explanation:

For the sake of showing work I will replace the empty space with an x like so...

[tex]\frac{1}{6} =\frac{2}{x}[/tex]

To find out what x is you must cross multiply (aka butterfly)

1*x = 2*6

1x = 12

x = 12

***If you don't understand the "cross multiply" technique  let me know in the comments and I'll be happy to explain.

To make these fractions equivalent the empty spot must be 12

To find the inverse of the given function, we need to switch the roles of x and y and solve for y.

To find the inverse of a function, we need to switch the roles of x and y, and then solve for y. So, let's start:

Given f(x) = 4x

Switching the roles, we have x = 4y

Now, solve for y:

x = 4y

Divide both sides by 4:

y = x/4

The inverse function is h(x) = x/4. Therefore, the correct option is h(x) = x/4.

Answer:

If you have to list your extraneous solutions somewhere, that would be x=0.

Step-by-step explanation:

Cool thing here is the radical, the thing with the square root, is already isolate.

So we need to square both sides as a first step.  (Whenever you raise both sides to even power, you must definitely check your solutions as some might not actually be solutions to the original equation)

So upon squaring both sides I get:

x^4+16=(x^2-4)^2

Now I will write (x^2-4)^2 as (x^2-4)(x^2-4) and foil it!  This gives me:

x^4+16=x^4-8x^2+16

Subtract x^4 and 16 on both sides:

       0=-8x^2

Divide both sides by -8

      0=x^2

Therefore x=0.

0 isn't actually a solution though because when you plug it in you get 4=-4 which is not true.

The equations representating the number of boxes Alonzo, Cory, and Bennett loaded are b = 0.7m, b = 1.4m, and b = 0.35m respectively. This is calculated based on the fact that Alonzo loaded 14 boxes in 20 minutes, and Cory and Bennett loaded twice and a quarter as much as Alonzo respectively.

On the basis given, Alonzo loaded 14 boxes in 20 minutes. So, the number of boxes loaded per minute, m , can be calculated as b = 14 boxes ÷ 20 minutes = 0.7 m.

Cory loaded twice as many boxes as Alonzo, so his equation is b = 2 * 0.7m = 1.4m.

Bennett loaded one fourth as many boxes as Cory, which means Bennett's equation can be determined as b = 1/4 * 1.4m = 0.35m.

The number of boxes loaded by each player can be represented by different equations. Alonzo and Bennett loaded boxes at the same rate.

Explanation:

The proportional relationship between the number of boxes, b, that each player loaded onto the truck and the number of minutes, m, spent loading boxes can be represented by the equations:

Alonzo: b = 0.71m

Bennett: b = 0.25c (where c is the number of boxes Cory loaded)

Cory: b = 2a (where a is the number of boxes Alonzo loaded)

Based on the given rates, Alonzo and Bennett loaded boxes at the same rate.

Step-by-step explanation:

(-1,4) is the vertex. reflect (-2,3) and (-3,0) onto the other side of the y-axis. you may use desmos to plug in the functions and the answer will be C, since it goes through the points given and reflected.

Final answer:

The function represented by the given set of points is f(x) = -x^2 - 2x + 3.

Explanation:

To determine the function represented by the given set of points, we can use the general form of a quadratic equation, y = ax^2 + bx + c. Substituting the points (-3,0), (-2,3), and (-1,4) into the equation, we can set up a system of equations and solve for the values of a, b, and c. The resulting function is f(x) = -x^2 - 2x + 3, which corresponds to option C.

Step-by-step explanation:

first you subtract 1 from 4 to get 3 and then you add 3 to -2 to get 1 so the coordinates are (3, 1)

The coordinate of B' is,

B' = (3, 1)

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

We have to given that;'

Rectangle ABCD has vertex coordinates A(1, -2), B(4, -2), C(4,-4), and

D(1, -4).

Since, It is translated 1 unit to the left and 3 units up.

Now, The rule for translated 1 unit to the left and 3 units up is,

(x, y) = (x - 1, y + 3)

So, The coordinate of B' is,

B' = (4 - 1, - 2 + 3)

1. simplify both sides of the equation by combining like terms

2. add 5 to both sides

3.divide both sides by -2

For this case we have the following equation:

[tex]-4x-5 + 2x = -11[/tex]

To solve, we add similar terms to the left side of the equation:

[tex]-2x-5 = -11[/tex]

We add 5 to both sides of the equation:

Answer:

m∠7 = 142°

Step-by-step explanation:

Note that a straight line's degree measurement = 180°

Note that the angle directly next to (to the left of) m∠7 has a measurement of 38°. Subtract 38 from 180:

180 - 38 = 142

m∠7 = 142°

~

Answer:

m∠7 = 142°

straight line's degree measurement = 180°

Then get the adjacent angle of 38. Subtract 38 from 180:

180 - 38 = 142

m∠7 = 142°

Answer:

(x²/4) + (y²/16) ≤ 1

Step-by-step explanation:

The general form of the ellipse in the graph is

x²/4 + y²/16 = 1

we want to find the inequality which represents the shaded area this will determine whether which of the following 2 choices are correct

Choice 1: x²/4 + y²/16 ≥ 1

Choice 2: x²/4 + y²/16 ≤ 1

we note that point (0,0) lies inside the shaded area. Which means if we substitute (0,0), it should create an equality that is valid.

try choice 1: 0²/4 + 0²/16  = 0 ≥ 1 (not valid because obviously zero is smaller than 1)  

try choice 1: 0²/4 + 0²/16  = 0 ≤ 1 (this is valid, hence choice 2  is the answer)
