find the slope of the line given:
y = mx+b
y = -3x/2 -7/2
slope = -3/2
the slope of the perpendicular line is the negative reciprocal
so answer is 2/3
Answer:
B. 128
Step-by-step explanation:
Answer: A) x + 4x = 35; 7 large stones and 28 small stones
======================================================
Explanation:
x = number of large stones
4x = number of small stones
x+4x = total number of stones = 35
x+4x = 35 is the equation to solve
-----------
Let's isolate x
x+4x = 35
5x = 35
x = 35/5
x = 7 large stones are needed
4x = 4*7 = 28 small stones are needed
From my work I believe it should be the third one.
Answer:
36.89°
Step-by-step explanation:
tan x = 15/20=3/4
x = 36.89
