Step-by-step explanation:
To find the expression for 5/a, you first need to solve the equation 5=a^x for a. To solve for a, raise both sides of the equation to the 1/x power.
5=a^x
5^(1/x)=(a^x)^(1/x) (now multipy exponents)
5^(1/x)=a (x*1/x = 1 - the exponent on a)
Now that the equation is solved for a, substitute the left side of the equation into 5/a. So,
5/a = 5/5^(1/x) (since the bases are the same, 5, subtract the exponents; note that the exponent in the numerator = 1)
5/a = 5^(1 - 1/x) (subtract by getting lcd, x)
5/a = 5^((x-1)/x)
Just to show you that this works: Let a = 25 and x = 1/2.
We know that 5 = a^x = 25^(1/2) = sqrt(25)=5.
Now, 5/a should equal 5/25 = 1/5, so let's plug the numbers into the new expression.
5/a = 5^((.5-1)/.5) (I'm using .5 instead of 1/2 so it's not so many parentheses.)

Step-by-step explanation:
If 1≤x≤3 and 3≤y≤5. The least possible average of 1/x and 1/y is:
(A) 2/3 (B) 3/5 (C) 4/15 (D) 8/15 (E) 4 /5
Answer:
(C) 4/15
Step-by-step explanation:
Given that 1 ≤ x ≤ 3 and we need to find the least value of 1/x. The least value of 1/x is gotten by taking the maximum value of x in the interval, hence the least value of 1/x = 1/5
Given that 3 ≤ y ≤ 5 and we need to find the least value of 1/y. The least value of 1/y is gotten by taking the maximum value of y in the interval, hence the least value of 1/y = 1/3
The least possible average of 1/x and 1/y = [tex]\frac{\frac{1}{x}+\frac{1}{y} }{2} =\frac{\frac{1}{5}+\frac{1}{3} }{2}=\frac{\frac{8}{15} }{2} =\frac{4}{15}[/tex]

What is the equation, in vertex form, of the quadratic function that has a vertex at V(−2, −6) and passes through point P(−4, −7)?
Answer:
f(x) = -¹/₄(x + 2)² - 6Step-by-step explanation:
The vertex form of an equation of the parabola:
f(x) = a(x - h)² + k
vertex is (-2, -6) so h = -2, k = -6
so:
f(x) = a(x - (-2))² + (-6)
f(x) = a(x + 2)² - 6
the parabola goes through the point (-4, -7) so for x=-4, f(x)=-7
-7 = a(-4+2)² - 6
-7 +6 = a(-2)² - 6 +6
- 1 = a(4)
a = -¹/₄
Therefore the equation of the parabola in vertex form:
f(x) = -¹/₄(x + 2)² - 6

r(t) = 9t - 4
r(4) = 9(4) - 4
divide both sides by 4
R(4) = 9 - 1
r = 8
What is x? please help
====================================================
Work Shown:
The three interior angles of any triangle always add to 180
82+54+x = 180
136+x = 180
x = 180-136
x = 44
---------------
Extra info:
If you need the value of y, then,
x+y = 180
y = 180-x
y = 180-44
y = 136
Or you could use the remote interior angle theorem to find y
y = 82+54
y = 136
The value of z is equal to y since these two angles are vertical angles.

Solve the given equation for x
2x-5 = 11
2x = 11+5
2x = 16
x = 16/2
x = 8
Then use this to compute 3x+10
3x+10 = 3*8+10 = 24+10 = 34
Rectangle ABCD is rotated 95° about point Q to create rectangle A'B'C'D'.
What is the area of rectangle A'B'C'D'?
Answer:
12
Step-by-step explanation:
Since both rectangles are of the same dimensions, simply multiply the width of the first box(2) and the length of the second box(6) together(2*6 = 12)
The area of rectangle before and after the 95° degrees rotation about point Q will be same.
What is the area of a Rectangle?
The area of a rectangle is the product of its length and width. Mathematically -
Area = length x width
Given is Rectangle ABCD is rotated 95° about point Q to create rectangle A'B'C'D'
The area of a rectangle depends on its length and width and not on its orientation. When a rectangle ABCD is rotated 95° about point Q to create rectangle A'B'C'D', in such case there will be no change in the dimensions of a rectangle. Therefore, the area of rectangle will remain same, irrespective of its orientation in plane.
Therefore, the area of rectangle before and after the 95° degrees rotation about point Q will be same.

A) 4/3
B) 3/4 (wrong)
C) -3/4
D) -4 (Wrong)
Answer:
The answer is option CStep-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
We have
[tex]m = \frac{4 - 7}{3 - - 1} = \frac{ - 3}{3 + 1} = - \frac{3}{4} \\ [/tex]
We have the final answer as

Use a model to divide. 45 by 6
Answer:
45 / 6
Step-by-step explanation:
Step-by-step explanation:
draw 3 boxes.
put 6 on the side of the one on the left and then put 3 over the first two boxes and then put one over the last box. then on the side of the last box draw three tiny ones.
i'll try and draw it
3 3 1
6 (18) (18) (6) then draw three tiny boxes.
you do this because 6 times 3 is 18 and if you do that twice its 36. then you do 6 times 1 which gives you 6. and 6 +36=42. then you add three boxes to make 45.
this probably made no sense. sorry
if y=27 when x=12, find x when y=-12
Answer:
x = - 36
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 27 when x = 12, then
k = yx = 27 × 12 = 324, thus
y = ← is the equation of variation
When y = - 9, then
- 9 = ( multiply both sides by x )
- 9x = 324 ( divide both sides by - 9 )
x = - 36
