Question

1) y = 4x – 3; 3) y = 7 – x;

Answer 1

Ответ:

0,75 и 7

Объяснение:

Это функция!!!

#1

например у=0

0=4х-3

х=0,75 или 3/4

#3

снова же у=0

0=7-х

х=7

Answer 2

The equations you provided are:

1. y = 4x - 3
2. y = 7 - x

These are linear equations in the form of y = mx + b, where m represents the slope of the line and b represents the y-intercept.

For equation 1: y = 4x - 3

• The slope (m) is 4, which means for every 1 unit increase in x, y increases by 4 units.
• The y-intercept (b) is -3, which means the line intersects the y-axis at the point (0, -3).

For equation 3: y = 7 - x

• The slope (m) is -1, which means for every 1 unit increase in x, y decreases by 1 unit.
• The y-intercept (b) is 7, which means the line intersects the y-axis at the point (0, 7).

These equations represent two lines on a Cartesian coordinate system. The first equation has a positive slope, indicating a line that rises as x increases. The second equation has a negative slope, indicating a line that falls as x increases.
