Answer: False
Step-by-step explanation:
Answer:option A is the correct answer.
Step-by-step explanation:
Ronald can read at a constant rate of p pages per minute.
If Roland can read a total number of N pages in minutes, then the equation representing the relationship between the number of pages, N and the time, m minutes would be
p pages = 1 minute
N pages = m minutes
Crossmultiplying, it becomes
p × m = N × 1
N = pm
The slope of the given line is the coefficient of x, 3/5. The slope of the perpendicular line will be the negative reciprocal of that: -1/(3/5) = -5/3.
The point-slope form of the equation for a line of slope m through point (h, k) can be written ...
... y = m(x -h) +k
For your point and the slope found above, this becomes
... y = (-5/3)(x -15) -5
When x=0, this is
... y = (-5/3)(-15) -5 = 20
The y-intercept is 20.
Answer: 180 once
Step-by-step explanation:
Make sure you set the two expressions equal to each other. 5.3(4x-2.6)=21.2x
NOw that that's done, distribute 5.3 to 4x and 2.6. 21.2x-13.78=21.2x Now you get all the x's on one side of the equation. But since they are the same number and subtracting one from the other would result in an answer of 0x. So the answer would be -13.78. I hope this is correct!
