If a line is perpendicular to -2x, the slope has the opposite reciprocal. In this case, the opposite reciprocal of -2x is 1/2x. Then you plug in the coordinates in the y = mx + b format:
5 = 1/2 (-2) + b
Then you solve for b and you should get b = 6
A surface amount of mass in a certain volume amount of matter an object contains.
I believe the second sentence is the answer since density is the measurement that compares the amount of matter that an object has to its volume.
Answer:
x ≈ 0.17
Step-by-step explanation:
17.52(32x) =9(10.43)
Isolate the variable by dividing each side by factors that dont contain the variable.
the answer is x ≈ 0.16743364
rounded down it is x ≈ 0.17
Answer:
The answer is y=20
Step-by-step explanation:
If you take a look at the attached picture you will notice that angles B and C are congruent, so that means they both are 25 degrees.
Next, add angles B and C together to get 50.
Then you take that 50 and add it to 70 in angle A's equation, and you will get 120.
Next, plug 120 into angle A's equation where the 70 was and you will have the equation 3y+120=180. (180 is there because that is what all the interior angles equal together.)
Next, slove the equation.
- 3y+120 = 180
- -120 -120
- 3y = 60
- /3 /3
- y = 20
And theres your answer, I hope I helped. Put any questions in the comments.
Answer:
c= 20h + 60
Step-by-step explanation:
The correct dependent variable for this equation is "c" cost of Mr Z's tutoring. The independent variable is "h" hours of tutoring. This is because the independent variable h hours should determine the cost of tutoring c. Therefore the equation can be interpreted: if there are h hours of tutoring which cost 20 per hour, total cost is equal c. Also slope of the equation is 20, coefficient of h.
