Ответ:
5.75
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + b^2 = 7^2
16 + b^2 = 49
49 - 16 = 33
√33 = 5.75
Ответ:
b = -6 (Answer d)
Step-by-step explanation:
The slope-intercept equation is y = -2x + b, and we know that the line passes through (-5, 4). Substitute -5 for x and 4 for y, to obtain:
4 = -2(-5) + b, or
4 = 10 + b, or
b = -6 (Answer d)
