Answer: 19.6 feet

Step-by-step explanation:

Using the Pythagorean theorem,

$x^2 +(x+6)^2 =48^2\\\\x^2 +x^2 +12x+36=2304\\\\2x^2 +12x-2268=0\\\\x^2 +6x-1134=0\\\\x=\frac{-6 \pm \sqrt{6^2 -4(1)(-1134)}}{2(1)}\\\\x \approx 30.8 \text{ } (x > 0)\\\\\implies x+(x+6) \approx 67.6\\\\\therefore (x+(x+6))-48 \approx 19.6$

Em 1 Graph the system of equations. { x−y=6 ,4x+y=4

muminat

Graphing the system of equations is shown in figure attached.

Solution set is (2,-4). The lines will intersect at (2,-4)

Step-by-step explanation:

We need to graph the system of equations. $x-y=6 ,4x+y=4$

First we will find value of x and y

Let:

$x-y=6\,\,eq(1)\\4x+y=4\,\,eq(2)$

Add eq(1) and eq(2)

$x-y=6\,\,\\4x+y=4\,\,\\------\\5x=10\\x=10/5\\x=2$

Putting value of x in eq(1) and finding y

$x-y=6\\2-y=6\\-y=6-2\\-y=4\\y=-4$

So, y=-4

Graphing the system of equations is shown in figure attached.

Solution set is (2,-4). The lines will intersect at (2,-4)

Sari is factoring the polynomial 2x2 + 5x + 3. What is the missing number in her factorization?

sergejj [24]

Answer:

The missing number in Sari's factorization is 3.

Step-by-step explanation:

The given polynomial is,

$=2x^2 + 5x + 3$

From quadratic equations, applying middle term factorization,

$=2x^2 + 2x+3x + 3$

$=2x(x + 1)+3(x + 1)$

$=(2x+3)(x + 1)$

Comparing this to the given expression, the missing number in Sari's factorization is 3.

PLEASE HELP ASAP I WILL GIVE BRAINSLET TO THE CORRECT ANSWER!!!!!!!!!!

Answer:

Therefore has one solution.

explanation:

Given equations:

6x + y = -7

-24x -7y = 25

Make y the subject:

6x + y = -7

y = -7 - 6x ..............equation 1

-24x -7y = 25

-7y = 25 + 24x

y = (25 + 24x)/-7 ..........equation 2

Solve them simultaneously:

(25 + 24x)/-7 = -7 - 6x

25 + 24x = -7 (-7 - 6x)

25 + 24x = 49 + 42x

42x - 24x = 25- 42

18x = -24

x = $-\frac{4}{3}$

Then y is:

y = -7 - 6x

y = -7 - 6( $-\frac{4}{3}$ )

y = 1

Has one separate value of x and y: ( $-\frac{4}{3}$ , 1 ); so it has one solution.
