I think a) would be the answer. I proceeded by elimination: the domaine of the function goes from 3 and continues to infinity, so that leaves with a) and b) as possible answers. Both have the same range and both of their functions reflect over the x axis, so we have to compare the two answer by looking at the position of the function in the graph. The function is in the first quadrant (top right corner), so the position of the function has to be at our right, which leads us to a).
Answer:
5(3√x) +9(3√x) = 15√x+27√x= 42√x
5∛x + 9∛x = 14∛x
Step-by-step explanation:
X-2 = 4+x
+2 +2
x = 6+x
-x -x
0 = 6
Answer: no solution / empty set / ∅
7(4 + 5) that should be it was it multiple choice ??
To find the equation for this line, we are going to use point-slope form. First, to find the perpendicular slope, we need to find the slope of the line 4y=5x - 8. To do this, we must transform this equation into slope-intercept form so we can determine the slope.
4y=5x-8
We should divide both sides of the equation by 4 to put the equation into slope-intercept form.
4y/4 = 5x/4 - 8/4
y = 5/4x - 2
Therefore, we can determine that the slope of this equation is 5/4. The slope of the line perpendicular to this line has the opposite reciprocal slope. To find the opposite reciprocal of 5/4, we must make it negative and switch the numerator and the denominator. The opposite reciprocal of 5/4 is -4/5.
Now, we must use this slope and the point we were given, (-5, 4), to write a new equation.
y = m(x-h) + k
y = -4/5(x + 5) + 4
y = -4/5x - 4 + 4
y = -4/5x
Therefore, your answer is y = -4/5x.
Hope this helps!
