The answer is A!
Hoped I help! Mark me brainly! It would help a lot !
Y = 1/2x - 3. Slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So the perpendicular line will have a slope of -2.
y = mx + b
slope(m) = -2
(1,-1)...x = 1 and y = -1
now we sub and find b, the y int
-1 = -2(1) + b
-1 = -2 + b
-1 + 2 = b
1 = b
so ur perpendicular equation is : y = -2x + 1
Answer:
C
Step-by-step explanation:
120° is an angle in the second quadrant.
The reference angle is the related acute angle in the first quadrant, that is
reference angle = 180° - 120° = 60° → C
Answer:
The number is 13.
Step-by-step explanation:
We are given the following in the question:
Let x be the variable, then according to the question
"The sum of eight and eleven times a number is 151"
We can write the equation:
Solving the equation, we can write:
Thus, the number is 13.
