Answer:
Step-by-step explanation:
Graph both equations
The solutions are the coordinates of the intetsection point between the lines.
The coordinates of the intersection point are approximatively (-0.23,-5.12)
So:
● x = -0.23
● y = -5.12
Answer:
No inverse function: (a), (b), (c)
Inverse function exists: (d)
Step-by-step explanation:
The graph of h(x) = (x - 2)^2 + 3 is a parabola that opens upward and has vertex at (2, 3). If the entire graph is drawn, and the horizontal line test then applied, h(x) would not have an inverse, because the horizontal line would intersect the parabolic graph twice.
Note that if we restricted the domain to x ≥ 2, the resulting graph would pass the horizontal line test. This would also be true for x ≥ 3, x ≥ 4, and so on. Not so for (a) x < 1. False for x > -5. True for x < 3. True for x > 4.
No inverse function: (a), (b), (c)
Inverse function exists: (d)
Answer:
Used car have the highest range of 75
Step-by-step explanation:
Yeah the type of car that have the highest range In monthly sales.
we know that
The range is the difference between the highest and the lowest value
First we,
calculate the range in monthly sales for the new car
highest value=51
lowest value=20
range=51-20
range=31
Secondly,we
calculate the range in monthly sales for used car
highest value=87
lowest value=12
range=87-12
range=75
Answer:-5k6
Step-by-step explanation:
Answer:
C) 28√17
Step-by-step explanation:
The perimeter is twice the sum of the two given side lengths, so is ...
P = 2(L +W) = 2(2√153 +4√68)
= 2(6√17 +8√17) = 2(14√17)
P = 28√17 . . . . . matches choice C
_____
This is about simplifying radicals. The applicable rules are ...
√(ab) = (√a)(√b)
√(a²) = |a|
__
153 = 9×17, so √153 = (√9)(√17) = 3√17
68 = 4×17, so √68 = (√4)(√17) = 2√17

<em>Comment on the problem presentation</em>
It would help if there were actually radicals in the radical expressions. We had to guess based on the spacing and the answer choices.
In any event, this problem can be worked with a calculator. Find the perimeter (≈115.45) and see which answer matches that. (That's what I did in order to verify my understanding of what the radical expressions were.)
