Answer:
Step-by-step explanation:
The formula to change a radical to rational (fractional) exponent is given below:
It means that the denominator of the fraction (in the rational exponent) goes OUTSIDE the root sign and the numerator goes as power to the number.
Using this, we can write as
Thus the rational exponent from is given by
Answer:
Domain:
Range:
Step-by-step explanation:
The domain is the span of x-values the graph covers.
The range is the span of y-values the graph covers.
The given graph is a quadratic. We can see that the x-values will extend infinitely in both directions.
Thus, the domain is all real numbers.
In set notation, this is:
From the graph, we can see that the maximum value is y=-2. The graph won't ever go above this.
So, the range is all real numbers less than or equal to -2.
In interval notation, this is:
And we are done :)
Answer:
$2.50
Step-by-step explanation:
7.50 - 5.00 = 2.50
They sell the shirts for $2.50 more than the original price so profit $2.50 off each shirt .
Reason:
Compare the given equation to the template y = mx+b
m = -1 = slope
b = 3 = y intercept
If it helps, then think of y = -x+3 as y = -1x+3
The slope of the line represented by the equation y = -x + 3 is -1.
The question is asking you to find the slope of the line represented by the equation y = -x + 3. In the standard form of a linear equation, y = mx + b, m is the slope of the line. The slope of a line tells you how steep the line is. It is determined by the ratio of the vertical change (the 'rise') to the horizontal change (the 'run') between any two points on the line. In this case, the equation of the line is y = -x + 3, so the slope of the line is the coefficient of x, which is -1. Therefore, the correct answer is A, -1. This might contrast with the figure A1 example, in which m is 3, but for your particular equation, m is -1.

Solve using elimination ?
Answer:
for the first one its x=30
for the second one its x=6
Step-by-step explanation:
its x=30 because at the end if you do the problem yourself, you would have to multiply 5×6 which is 30.
im not sure why its x=6 on that one i might be wrong but i did it but im also confused on it but i tried so yeah maybe it is.
