Good morning ☕️

______

Answer:

x=4

___________________

Step-by-step explanation:

-Solving:

2x + 5 – 3 (2x - 7) = 2 (3x – 5) – 4

2x + 5 – 6x + 21 = 6x – 10 – 4

-4x + 26 = 6x - 14

10x= 26+14

10x=40

x=4

-Checking:

x=4

2(4) + 5 – 3 (2(4) - 7) = 8+5-3(8-7) = 13-3(1) =13-3=10

2 (3(4) – 5) – 4 = 2(12-5)-4 = 2(7)-4=14-4=10.

Please help with the following question

sasho [114]

We have:
The generic equation of the line is: y-yo = m (x-xo)
The slope is:
m = (y2-y1) / (x2-x1)
m = (- 2-0) / (3-0)
m = -2 / 3
We choose an ordered pair
(xo, yo) = (0, 0)
Substituting values:
y-0 = (- 2/3) (x-0)
Rewriting:
y = (- 2/3) x
Answer:
The equation of the line is:
y = (- 2/3) x

What is the slope of (10, 4), (4, 15)?

kakasveta [241]

Answer:

Slope is -11/6

Step-by-step explanation:

$Given \: points \: are \: (10,4) \: \: and \: (4,15) \\ slope \: = \frac{y2 - y1}{x2 - x1} \\ here \: x1 = 10 \: \: \: y1 = 4 \\ and \: \: x2 = 4 \: \: \: and \: \: y2 = 15 \\ on \: substituting \: the \: values \: in \: formula \\ slope = \frac{15 - 4}{4 - 10} \\ = \frac{11}{ - 6}$
