the correct answer to this and im not 100% sure but I think its 51.
xis less than or equal to -3
it will be c:
because move -2 to the right side of the sign which becomes + 2
-3x>_ 7+2
-3x_>9
divide -3 both sides
change the sign
x_<-3
A.They are perpendicular because their slopes are equal.
B.They are perpendicular because their slopes are negative reciprocals.
C.They are not perpendicular because their slopes are equal.
D.They are not perpendicular because their slopes are not negative reciprocals.
we know that
If two lines are perpendicular then, the product of their slopes is equal to minus one, that means that their slopes are negative reciprocals
so
Step
Find the slope of the line HJ
we know that
the slope between two points is equal to
substitute the values
Step
Find the slope of the line HJ
we know that
the slope between two points is equal to
substitute the values
Step
Verify if the two lines are perpendicular
Find the product m1 by m2
so
--------> the slopes are not negative reciprocals
therefore
the answer is the option
D.They are not perpendicular because their slopes are not negative reciprocals
Answer:
The domain is all real numbers. The range is {y|y ≤ 16}.
Step-by-step explanation:
The vertex of a parabola is given by
.
As a = -1, b = -2, c= 15 here, then the vertex is at (1,16).
As a is negative, it opens downward, so the range is {y|y ≤ 16}.
Meanwhile, all parabolic functions have a domain of .
Answer:
The domain is all real numbers and the range is {y|y <= 16}
Its the second choice.
Step-by-step explanation:
took the test on edge, hope it helps!
To determine your age, use the equation 200 - 2x = 16 to isolate the variable x and solve for its value. After performing these operations, we find that x = 92. Therefore, you are 92 years old.
To find out how old you are, we can set up an equation. Let's assume your age is x. Then, 200 reduced by 2 times your age can be written as 200 - 2x. According to the question, this expression is equal to 16. So, we can write the equation as 200 - 2x = 16. To solve this equation, we need to isolate the variable x. We can do this by subtracting 200 from both sides of the equation and then dividing by -2. After performing these operations, we find that x = 92. Therefore, you are 92 years old.
