Step-by-step explanation:
the slope is the factor of x in an equation
y = ax + b
we have here
3y = -5x + 21
to get to the general format above we need to divide everything by 3 :
y = -5/3 x + 7
so, we see, the slope is -5/3.
the perpendicular (angle of 90°) slope is the original slope turned upside-down and with flipped sign :
3/5
so, I guess the correct answer option is c.
but it is not clear what you wrote there, as there is a "-" sign somehow in all 4 answers.
Answer:
72.2 is the correct answer
Step-by-step explanation:
Answer:
x = 21
Step-by-step explanation:
3x - 23 = 40
Collect like terms
3x = 40 + 23
3x = 63
Divide through by 3
3x/3 = 63/3
x = 21
Check
3x - 23 = 40
since x = 21
3(21) - 23 = 40
63 - 23 = 40
40 = 40
well the answer is 100
reason : m and n are parellel and 100 degree is already given ... so it its corresponding angle will be 100
p and q are parrelel too...so the corresponding angle 100 degree is the exterior angle of p and q ... so its 100
