Answer:
x=-117/4
Step-by-step explanation:
5x-15+130=x-2
5x-x+115=-2
4x+115=-2
4x=-2-115
4x=-117
x=-117/4
Answer:
1728
Step-by-step explanation:
There are 12 numbers that can be used for the first number; 12 for the second number; and 12 for the third number. This means there are a total of
12(12)(12) = 1728 combinations.
Answer:
x = 83°
Step-by-step explanation:
41, 56 and the missing angle = 180° ( form a straight angle )
missing angle = 180° - (41 + 56)° = 180° - 97° = 83°
The angle x and the missing angle are vertically opposite and congruent
Hence x = 83°
Answer:
Line d y = -3x -3
Line e y = -3x -1
Line f y= -3x+2
To write the equation of a line, you need the slope and the y-intercept. The slope of each line is -3. Find the y-intercept on the graph and then substitute it into the equation y = mx+b for b.
Line d has y-intercept (0,-3)
y = -3x -3
Line e has y-intercept (0,-1)
y = -3x -1
Line f has y-intercept (0,2)
y= -3x+2
