What value of x is in the solution set of –5x – 15 > 10 + 20x? –2 –1 0 1
stealth61 [152]

Answer:

-2

Step-by-step explanation:

5x – 15 > 10 + 20x

Subtract 5x from each side

5x – 15-5x > 10 + 20x-5x

-15 > 10+15x

Subtract 10 from each side

-15-10 >15x

-25 > 15x

Divide each side by 15

-25/15 > x

-5/3 > x

X must be less than -1  2/3

The only value that is less than -1 2/3 is -2

Write the equation of the line that passes through A(-3,-2) and B(1,6).
topjm [15]

Answer:

<h2>y = 2x+4</h2>

Step-by-step explanation:

A(-3,-2) and B(1,6).\\\\x_1 = -3\\y_1 = -2\\x_2 = 1\\y_2 =6\\\frac{y-y_1}{x-x_1} =\frac{y_2-y_1}{x_2-x_1} \\\frac{y -(-2)}{x -(-3)} =\frac{6-(-2)}{1-(-3)}\\\frac{y+2}{x+3} = \frac{6+2}{1+3} \\\frac{y+2}{x+3} = \frac{8}{4} \\Cross-multiply\\4(y+2) =8(x+3)\\4y +8 =8x+24\\4y = 8x +24-8\\4y = 8x+16 \\OR\\ y = 2x+4

Is the value of the variables used in this metric system?
Marat540 [252]

Solution:

a=-2 b=1 c=4 d=0

Analysis:

When we multiply a matrix by a constant, we multiply each term of the matrix by the constant.

In this case, as we need to find the value of the initial matrix, we can divide each term of the matrix by the constant. In this case, let´s divide by -5

So, it would be:

a=10/-5 a=-2

b=-5/-5 b=1

c=-20/-5 c=4

d=0/-5 d=0

What is 3(2x-4)=6(x-2)<br> with solving steps?
dedylja [7]

Answer:

true for all x

Step-by-step explanation:

3(2x-4)=6(x-2)

Distribute

6x - 12 = 6x -12

Subtract 6x from each side

6x-12 -6x = 6x-12-6x

-12 =-12

Since this is always true, there are infinite solutions
