Answer:
16 strips
Step-by-step explanation:
37.75/2.25=16.8...
Since you can't cut a fraction of what they need, 16 should be the answer
hope this helps :)
Answer:
y = -2x - 4
Step-by-step explanation:
So we have the x intercept and a line perpendicular to the one we are trying to find.
Perpendicular deals with the slope. Perpendicular slopes are negative reciprocals of each other, or in other words, if the slope is m the negative reciprocal is -1/m.
the slope of the perpendicular line is 1/2 so that means the negative reciprocal is -2.
x intercept is when y=0, so the point is (-2, 0). So that means the equation to make this point with the slope of -2 will look like this
y = mx + b
0 = -2*-2 + b
-4 = b
Now to get into the line we just plug in m and b into y = mx + b
y = mx + b
y = -2x - 4
And to check if you plug in -4 you'll get y = 0
In one million there are 30492 positive numbers with the sum of their digits equal to 19
Answer:
Step-by-step explanation:
Domain: the set of all permissible input values. In this particular case, x cannot be -3, because that would cause division by zero. Thus, the domain is (-∞, -3) ∪ (-3,∞)
Range: the range consists of the set of all values of y that are possible. Looking at the parent function, y = 1/x, we see that the range of that function is (-∞, 0) ∪ (0,∞); in other words, y gets close to but never actually reaches zero. This is also true of y = -1 / (x + 3).
Thus, the desired range is (-∞, 0) ∪ (0,∞).
