Step-by-step explanation:
it is the same so there is infinite solutions
Plz mark brainlist
Answer:
Infinitely many solutions
Step-by-step explanation:
Original Equation:
-9(z + 8) = -9z - 72
Use distributive property.
-9 x z = -9z
-9 x 8 = -72
-9z - 72 = -9z - 72
That means there are infinte solutions.

A mathematician threw a party. She told her guests, “I have a riddle for you. I have three daughters. The product of their ages is 72. The sum of their ages is the same as my house number. How old are my daughters?” The guests went outside to look at the house number. They thought for a few minutes, and then said, “This riddle can’t be solved!” The mathematician said, “Oh yes, I forgot to tell you the last clue. My youngest daughter prefers strawberry ice cream.” With this last clue, the guests could solve the riddle. How old are the mathematician’s daughters?
Answer:
108 years old
Step-by-step explanation:
first you divide 72 by 2 and you get 36
then you multiply 36 by 3 and you get 108 which is the answer

Answer:
15/4

15/4
Step-by-step explanation:
to isolate x you must divide 4/15 on both sides
to divide by fractions, multiply by the reciprocal.
the reciprocal of 4/15 is 15/4, so 15/4 is multiplied on both sides

The ratio of Maggie's age now to her brother Steven's age now is 2:3. In ten years, the ratio of their ages will be 4:5. How old in Maggie now? Do not label years old in your answer.
Answer: Maggie is currently 10 years old.
====================================================
Explanation:
M = Maggie's age today
S = Steven's age today
The ratio of their current ages, specifically Maggie's age to Stevens age, is 2:3. So 2/3 = M/S
We can cross multiply to get 2S = 3M and divide both sides by 2 getting S = 3M/2 = 1.5M
So whatever Maggie's age is, we multiply by 1.5 to get Steven's age. This only applies to their current present day ages.
----------------------
In 10 years, Maggie will be M+10 years old and Steven will be S+10 years old.
The ratio of their ages at this point in time is 4:5, so,
4/5 = (M+10)/(S+10)
4(S+10) = 5(M+10) ..... cross multiply
4S+40 = 5M+50
4S-5M = 50-40
4S-5M = 10
4(1.5M) - 5M = 10 .... plug in S = 1.5M
6M - 5M = 10
M = 10
Maggie is currently 10 years old.
----------------------
Extra info:
Use the value of M to find S.
S = 1.5*M
S = 1.5*10
S = 15
So Steven is currently 15 years old.
The ratio of Maggie's current age to Steven's current age is M/S = 10/15 = 2/3 which turns into 2:3
In 10 years, Maggie will be M+10 = 10+10 = 20 and Steven will be S+10 = 15+10 = 25
The ratio of their ages now is (M+10)/(S+10) = 20/25 = 4/5 leading to the ratio 4:5
This confirms our answers.

The distance a trucker travels on the highway at 65 mph can be modeled by the function f(x)=65x , where x is the time in hours and f(x) is the distance is miles. What are the domain and range of the function? The domain of the function is The range of the function is
Answer:
Step-by-step explanation:
The domain are the values of the input variables x that will make the function exist.
Given the function:
f(x) = 65x
Note that x is the time and time cannot be negative. Hence the domain of the function will be all positive real numbers. It is expressed according to the set notation:
DOMAIN: [0, ∞)
The range are the values of the output function f(x) that will make the function exist. Since the minimum value of x is 0, then
at x =0 , f(x) = 65(0)
f(x) = 0
The minimum value of f(x) = 0
Hence the range can also exist on all positive real number.
RANGE: [0, ∞)

What is the factorization of the polynomial below?
16x^2-9
Answer:
(4x+3) × (4x−3)
Step-by-step explanation:
The explanation is on the screenshot if you need it
The resulting simplified form of the expression is (4x +3)(4x-3)
Given the polynomial equation 16x^2-9
This can be expressed as the square of monomials as shown:
16x^2 = (4 * 4 * x * x)
16x^2 = (4x)^2
Similarly, 9 = 3^2
Substituting into the expression, we will have:
16x^2-9 = (4x)^2 - 3^2
According to difference of two square a^2 - b^2 = (a+b)(a-b)
(4x)^2 - 3^2 = (4x +3)(4x-3)
Hence the resulting simplified form of the expression is (4x +3)(4x-3)

Answer:
y=[tex]\frac{-4}{5}[/tex]x+7
Step by Step Explanation:
Slope intercept form is y=mx+b
So to convert this to slope-intercept form, you would first need to move the x value to the other side of the equation through subtracting it on both sides. This would make the equation 10y = -8x +70
Next, you would divide both sides by 10 to get the y integer alone. This would make the equation y=[tex]\frac{-8}{10}[/tex]x + 7
Lastly, just simply that fraction before the x integer, and you get your answer!

A certain company designs and ships boxes of golf balls. Each box must weigh 540 grams. Write two absolute value expressions that represent the number of grams a box weighing g grams is away from the desired weight. Select all that apply. Multiple select question. cross out A) 540−||g|| cross out B) ||g||−540 cross out C) ||540−g|| cross out D) ||g+540|| cross out E) ||g−540||
Answer:
|540 - g|
|g - 540|
Step-by-step explanation:
Given that:
Weight of box = g
Desired weight = 540
Hence, to obtain the difference between the weight of the box and the desired weight ; the result could either be lesser or larger then desired weight ; However , since we do not know If it is lesser or higher, then we take the absolute value ; so that we always obtain a positive value.
The difference will thus be either ;
Weight of box - desired weight : |g - 540|
OR
deaired weight - weight of box : |540 - g|
