4x-7=29 < do you understand how to set that up? Now, the goal is to “get x by itself.”

4x-7=29< now add the 7 to the 29. When you cross an equals sign you change the (+/-) sign of the number you’re moving.

4x= 36< now you will just divide by 4 on both sides. This will give you x by itself on the left side of the equals sign.

x=36/4 which is 9

X=9 :))

Let the unknown number be x.

"Subtract 7 from the product of 4 and a number"

4x - 7

"the number added to 29"

x + 29

Doing the first expression results in the second expression, so the expressions are equal.

4x - 7 = x + 29

Add 7 to both sides.

4x = x + 36

Subtract x from both sides.

3x = 36

Divide both sides by 3.

x = 12

Answer: The number is 12.

Check: Subtract 7 from the product of 4 and 12:

4 * 12 - 7 = 48 - 7 = 41

12 added to 29:

12 + 29 = 41

Both expressions equal 41, so 12 is the correct value for the number.

Change the equation of the parent square root function to represent the equation of the graphed function. Enter the correct answ

Dennis_Churaev [7]

The equation of the parent square root function to represent the equation of the graphed function will be, y=√x-2

According to the statement

we have to show the square root function as a equation in the graphical representation.

So,

we know that the definition of a

Graph a diagram showing the relation between variable quantities, typically of two variables and it also show the relation between more than two variables.

Now, we know that the definition of Equation is a mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

And the equation obtained from the graph is a y=√x-2 by a some calculations in the graph.

So, The equation of the parent square root function to represent the equation of the graphed function will be, y=√x-2

The height of a trapezoid is 6 in. And its area is 48 in2. One base of the trapezoid is 6 inches longer than the other base. Wha

omeli [17]

Answer:

5 in
11 in

Step-by-step explanation:

Let x represent the length of the shorter base in inches. Then the longer base has length x+6. The area of the trapezoid is given by the formula ...

A = (1/2)(b1 +b2)h

Filling in the values we know, we have ...

48 = (1/2)(x +(x+6))(6)

16 = 2x +6 . . . . . divide by 3

10 = 2x . . . . . . . . subtract 6

5 = x . . . . . . . . . . divide by 2

(x+6) = 11 . . . . . . find the longer base

The lengths of the bases are 5 inches and 11 inches. We found them by solving an equation relating area to base length.

A teacher plans to buy the same number of notebooks and rulers for his classroom. Each notebook costs $2 and each ruler costs $1

Paladinen [302]

Answer:

3x=total amount of money, 3x

Step-by-step explanation:

Because the number of notes books is the same (x and x), you can simply add them.

Basically, the equation is 1x+2x= total cost but you can add 1x and 2x because they have the same variable

To the nearest whole degree what angle measure has a tangent of 5.6922

Softa [21]

Answer:

<h3>80° has a tangent of 5.6922..</h3>

Step-by-step explanation:

We are given value of tangent trigonometric ratio = 5.6922.

We need to find the angle in degrees whose measure has a tangent of 5.6922..

So, we need to find the value of $tan^{-1}(5.6922)$ .

On plugging $tan^{-1}(5.6922)$ in calculator, we get

80.03°.

Now, we need to round it to the nearest whole degree.

Therefore, 80.03°≈ 80°.

<h3>Therefore, 80° has a tangent of 5.6922..</h3>

A football is kicked up from ground level at an initial upward velocity of 80 ft./s. The equation h=-16t^2 + 80t give the height

bixtya [17]

Answer:

Step-by-step explanation:

Note that the given height equation, which is a quadratic) has a graph that opens downward. Borrowing the quadratic formula, we find the roots of this equation, that is, the t values at which h(t) = 0:

The coefficients of this equation are a = -16, b = 80 and c = 0.

We need to find the roots of this quadratic. By the quadratic formula,

-(80) ±√(80² - 4(-16)(0) ) -80 ± 0

t = ------------------------------------- = ----------------- = -5/2 and -5/2 (seconds).

2(-16) -32

The initial height is 0 at t = 0 seconds and the final height 0 at 5/2 seconds.
