Answer:

x1 = -4, x2 = -16

Step-by-step explanation:

1.- equal the equation to 0

x^2 + 20x + 100 - 36 = 0

x^2 + 20x + 64

2.- factor to simplify.

(x + 4)(x + 16) = 0

3.- equal each factor to 0 and solve for x.

x + 4 = 0, x = -4

x + 16 = 0, x = -16

Answer:

-8>x>6

Step-by-step explanation:

I 5x+5I +22> 57subtract 22 on both sides

I5x+5I >35

SPLIT

5x+5>35 5x+5< -35 ( flip sign and 35 negative)

5x>30 5x< -40

x>6 x< -8

Draw a number line Write zero in the middle

From zero count to the left until- 8 make an open circle because- 8 is not included From -8 draw an arrow to the left (because x is less than -8)

From zero count to the right until 6 Make an open circle bc 6 is not included. From 6 draw an arrow to the right (because x is more than 6)

What is the solution to the system of equations y23x3 x 2

bija089 [108]

The Solution for the given system of equations is (-2) and $(\frac{5}{3})$ .

The given are linear equations as follow:
y = $\frac{2}{3}x$ + 3 .. ... ...(1)
and x = -2. .. .... ...(2)

We already know the first part of the solution (x) which is -2. We can find the other part (y) by putting the value of equation (2) in equation (1).

By putting the values of x in equation (1), we get

y = $(\frac{2}{3})(-2)$ + 3
y = $\frac{-4}{3}$ + 3

Taking the L. C. M of denominators which will be '3', we get:

y = $\frac{-4 + 9}{3}$

y = $\frac{5}{3}$

So the second part (y) of the solution of the given equation is $\frac{5}{3}$ .

Hence, the overall solution to the given system of equation is $(-2, \frac{5}{3})$ .
