Answer:
(D)
Step-by-step explanation:
Area (shaded) = Area (large rectangle) - Area (small rectangle)
= (4x + 3)(4x - 3) - (8x + 9)(2x - 1)
= 16x² - 9 - [16x² + 18x - 8x - 9]
= -10x
The correct option is (D)

What is the constant of proportional in the equation Y equals 5/9 X
9514 1404 393
Answer:
5/9
Step-by-step explanation:
Compare the given equation ...
y = (5/9)x
to the equation for proportionality ...
y = rx
where r is the constant of proportionality.
Matching the two patterns, you should be able to see that r = 5/9.
The constant of proportionality is 5/9.

Answer:
c=30
Step-by-step explanation:
Inverse: 22 + 8 = 30
c = 30
Answer:
c = 30
Step-by-step explanation:
Step 1: Add 8 to both sides.
[tex]c-8+8=22+8[/tex] [tex]c=30[/tex]Step 2: Check if solution is correct.
[tex]30-8=22[/tex] [tex]22=22[/tex]Therefore, the answer is c = 30.

A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent. This can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days. How many phone calls should she expect after a week?
Answer:
17
Step-by-step explanation:
After a week he can expect 17 calls.
Given that,
A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent.
This can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days.
How many phone calls should she expect after a week is to be determined.
The function which is in format f(x) =aˣ where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here,
in 1 week = 7 Days
Now,
D = x
y = 30(0.92)ˣ
now put x = 7
y = 30(0.92)⁷
y = 30 * 0.55
y ≈ 17
Thus, After a week he can expect 17 calls.

#SPJ2
what is the approximate height of the rice container if the radius is 2.5 in. and the volume is 235.5 in cubed
Answer:
12 in
Step-by-step explanation:
r = 2.5 in
V = 235.5 in³
Find h
Use V = πr²h
so 235.5 = 3.14 * 2.5² * h
235.5 = 19.625 h
h = 235.5/19.625 = 12 in

Answer:
The answer is 6
Step-by-step explanation:
2.3... where the 3s go on forever is the same as 2 + 1/3 or 2 & 1/3
The whole number portions add to 3+2 = 5, and we add on the carry of 1 to get 5+1 = 6
3 & 2/3 = 3 + 2/3 = 3 + 0.667 = 3.667 approximately
adding this onto 2.333 leads to
3.667 + 2.333 = 6
Technically the 6's go on forever in the decimal form of 3 & 2/3, but rounding wont have an effect on the answer when we add
The equation 4(x – 3)2 – 5 = 139 has two solutions: one positive and one negative. What is the
negative solution?
7.
Answer:
Step-by-step explanation:
4(x-3)2-5 = 139
(4x-12)-5=139
-20x + 60 = 139
-20x +60 - (60) = 139- 60
-20x = 79 divide both sides by -20
x = -3.95
PLEASE SOLVE! IT'S REALLY EASY, BUT MY BRAIN IS DEAD AT THE MOMENT.
Answer:
x = 30 over 11
Step-by-step explanation:
6(9x-5)-4(3+2x)-3(8x-20) = 24
54x-30-12-8x-24x+6 = 24
22x = 24+36
22x = 60
then divide both sides by 22
x = 30 over 11

The function f is defined by f(x) = - |x|, The expression for g (x) will be g (x) = - |x|+3.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that the function is,
f(x) = - |x|,
Geometric transformation is the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is obtained from the graph that the point for the function g (x) is translated by the 3 units right.
Thus, the function f is defined by f(x) = - |x|, The expression for g (x) will be g (x) = - |x|+3.

#SPJ2
The area of a rectangle is 75 square feet, and the length is 25 feet. What is the perimeter?
Answer:
56 feet
Step-by-step explanation:
75/25=3 feet
this is another side.
(3+25)x2+56 feets
Answer:
75ft.
Step-by-step explanation:
What you do is subtract two 25s from the area (because there are two sides for length) which gives you 25. The width would be half of that which is 12.5. Then add two widths (12.5+12.5=25), and add that to two lengths (25+25=50). The answer is 75ft as well. Please tell me if I'm wrong.
Solve for x 5x+10=7x+18
Answer:
I think it is x=-4
Step-by-step explanation:
Step 1: Subtract 7x from both sides.
5x+10−7x=7x+18−7x
−2x+10=18
Step 2: Subtract 10 from both sides.
−2x+10−10=18−10
−2x=8
Step 3: Divide both sides by -2.
-2x/-2=8/-2
