Answer:

3 + 4/(x+2)

Step-by-step explanation:

4-[(x+3)/ ((x^2 +5x +6)/(x-2))]=

4- [(x+3)*(x-2)/(x^2 +5x +6))]=

4- [(x+3)(x-2)/(x+3)(x+2)]=

4-(x-2)/(x+2)=

(4x+8-x+2)/(x+2)=

(3x+10)/(x+2)=

3 + 4/(x+2)

Solve for x. 5x - 1 = 26 x = x = 5 x = -5

Doss [256]

Answer:

x = 27/5

Step-by-step explanation:

5x - 1 = 26

Add 1 to each side

5x - 1 = 26

5x-1+1 = 26+1

5x = 27

Divide each side by 5

5x/5 = 27/5

x = 27/5

Write an equation in slope-intercept form for this line.

sineoko [7]

Answer:

y = $\frac{3}{2}$ x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = $\frac{3}{2}$ , then

y = $\frac{3}{2}$ x + c ← is the partial equation

To find c substitute (- 4, - 7 ) into the partial equation

- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1

y = $\frac{3}{2}$ x - 1 ← equation of line

Answer:

Fraction of the students in the 7th grade class carry a cell phone = 3/5

24 students carry a cell phone

Step-by-step explanation:

40 students in the 7th grade, 60% of the students carry a cell phone.

so 40 x 0.6 = 24 students carry a cell phone

24/40 = 3/5

Which system is equivalent to 3x squared - 4y squared = 25 over -6x squared -2y squared = 11

TEA [102]

So we are given the following system:
$3x^2-4y^2=25\\
-6x^2-2y^2=11\\\text{Multiply the second equation by -2:}\\12x^2+4y^2=-22\\\text{Add to the first equation we get:}\\15x^2=3
\text{ therefore }x=\pm \sqrt{ \frac{1}{5} }$
Using the first equation again we get:
$3x^2-4y^2=25\\
3x^2=4y^2+25\\
x^2= \frac{1}{3}(4y^2+25)\\x^2= \frac{1}{3}(4 \frac{1}{5} +25)\\= \frac{43}{5}\\x=\pm \sqrt{ \frac{43}{5} }$
