I need points soo I can post my question an get help my self...
Answer:
y = (3/2)x - 5/2
Step-by-step explanation: 5 + 2x
-2x-3y=5, solved for y, is y = ------------- , with a slope of -2/3. A line
-3
perpendicular to this one has a slope which is the negative reciprocal of -2/3, that is, +3/2. Using the slope-intercept formula, we calculate the y-intercept of the line that is perpendicular to the given one and passes through (1/3, -2): y = mx + b => -2 = (3/2)(1/3) + b, or
-2 = 1/2 + b. Thus, b must be -2 1/2, or -5/2.
The desired equation is y = (3/2)x - 5/2.
These will be the answers
In a quadratic function, y = a(x²) the smaller the coefficient "a", the larger is the parabola:
From widest to narrowest:
1) y=1/3x² (Widest)
2) y= -1/2x² (Wider)
3) y=-9x² (narrowest)
Answer:
Thomas travels <em>64 miles each hour</em>.
Step-by-step explanation:
Distance traveled by train = 328 miles
Time taken to travel by train =
We know that speed can be formulate as:

Speed is equal the total distance traveled for the one unit time.
In our case, speed is total distance traveled in miles in 1 hour.
So, using above formula:

As per definition of Speed, Thomas travels <em>64 miles each hour</em>.
