Answer:

The value of x = 4√5

Step-by-step explanation:

<u>Points to remember</u>

For a right angled triangle

Hypotenuse² = Base² + Height²

<u>To find the value of x</u>

From the figure we can see a right angled triangle with,

hypotenuse = 6 and height = 4

Value of x = 2 * base

we have, Hypotenuse² =  + Height²

Base² = Hypotenuse² - Height²

 = 6² - 4²

 = 36 - 16  = 20

Base = √20 = 2√5

x = 2 * 2√5 = 4√5

The value of x = 4√5

Answer:

x = 8.9 (nearest tenth)

Step-by-step explanation:

6^2 - 4^2 = 36 - 16 = 20

So

x = 2 * (√20)

x = 2 * 4.47

x = 8.94

Y=4x(8-x). Linear or nonlinear? explain.
NemiM [27]

Answer:

not linear

Step-by-step explanation:

this equation becomes y = -4x² + 32x which is a quadratic equation that, when graphed, forms an upside down u-shaped curve (upside down because the x² term is negative; if it's positive then the curve is u-shaped)

Answer:

D. (2, 6)

General Formulas and Concepts:

<u>Algebra I</u>

  • Solving systems of equations by graphing

Step-by-step explanation:

The solution set of the systems would be where the 2 lines intersect. We see from the graph that our 2 lines intersect at (2, 6). Therefore, our solution set would be D. (2, 6).

6-2(x+6)=3x+4 <br><br><br> ...............................
juin [17]

Answer:

x=−2

Step-by-step explanation:

1 Expand.

6-2x-12=3x+4

6−2x−12=3x+4

2 Simplify  6-2x-126−2x−12  to  -2x-6−2x−6.

-2x-6=3x+4

−2x−6=3x+4

3 Add 2x2x to both sides.

-6=3x+4+2x

−6=3x+4+2x

4 Simplify  3x+4+2x3x+4+2x  to  5x+45x+4.

-6=5x+4

−6=5x+4

5 Subtract 44 from both sides.

-6-4=5x

−6−4=5x

6 Simplify  -6-4−6−4  to  -10−10.

-10=5x

−10=5x

7 Divide both sides by 55.

-\frac{10}{5}=x

−

10

​

=x

8 Simplify  \frac{10}{5}

  to  22.

-2=x

−2=x

9 Switch sides.

x=-2

x=−2
