Answer:
[tex]\Large \boxed{f(3)=11}[/tex]
Step-by-step explanation:
[tex]f(x)=2x+5[/tex]
For f(3), the input for the function f(x) is 3.
Let x (input) = 3.
[tex]f(3)=2(3)+5 \\\\ f(3)=6+5 \\\\ f(3)=11[/tex]
Answer:
11
Step-by-step explanation:
f(x)=2x+5
Let x = 3
f(3) = 2*3+5
= 6+5
= 11

Answer:
Commutative Property
Associative property
Additive inverse
Identity property
Step-by-step explanation:
In a commutative property multiplication and addition which posses commutative property takes place without considering the order of arrangement of data
12.2 + 18.6 + –4.3 + (–18.6)
12.2 + –4.3 + 18.6 + (–18.6)
The second step results into the presence of a commutative property.
The next step 12.2 + –4.3 + [18.6 + (–18.6)] is an associative property because here, re-grouping of numbers which gives the same result takes place
[18.6 + (–18.6)] is an additive inverse since the result is zero. Additive inverse occurs when the addition of a number to another number results into zero
12.2 + –4.3 + (0) is an Identity property
Identity property occurs when the addition of any number with zero eventually resulted into that number.
Answer:
Commutative Property
Associative property
Additive inverse
Identity property

How many integers at between 15 and 63?
Answer:
47
Step-by-step explanation:
Ok first lets do this with small numbers like 10 and 5. How many integers are between 10 and 5? which does not include 10 or 5. You do 10 minus 5 which is 5, but if you count how many integers are between them with your fingers you get 4.
so now you know to get the integers between 2 large numbers you subtract like normal then you mines a 1.
so 63 - 15 - 1 = 47
There are 47 integers between 15 and 63
Hope this helps :)
There have been 47 integer arithmetic in the range of 15 to 63.
Number of integer between two number = Highest number - Lowest number - 1
So,
Number of integer between 15 and 63
63 - 15 - 1
63 - 16= 47
So,
Number of integer between 15 and 63 = 47

Last Sunday a certain store sold copies of Newspaper A for $1.00 each and copies of Newspaper B for $1.25 each, and the store sold no other newspapers that day. If r percent of the store's revenue from newspaper sales was from Newspaper A and if p percent of the newspapers that the store sold were copies of Newspaper B. Write an expression in terms of r and p.
Answer:
[tex]\mathbf{r = \dfrac{400p }{ 500 -p}}[/tex]
Step-by-step explanation:
Given that:
Last Sunday a certain store sold copies of Newspaper A for $1.00 each
A = 1
and copies of Newspaper B for $1.25 each,
B = 1.25
and the store sold no other newspapers that day. If r percent of the store's revenue from newspaper sales was from Newspaper A and if p percent of the newspapers that the store sold were copies of Newspaper B.
Then ;
[tex]r = \dfrac{A}{A+1.25B} \times 100[/tex] --- (1)
[tex]p = \dfrac{A}{A+B} \times 100[/tex] --- (2)
From (2)
[tex]A+B = \dfrac{A}{p} \times 100[/tex]
[tex]B = \dfrac{A}{p} \times 100-A[/tex]
[tex]B = \dfrac{A( 100-p)}{p}[/tex]
Substituting the value of B into equation (1), we have:
[tex]r = \dfrac{A}{A+1.25 \times { \dfrac{A( 100-p)}{p}}} \times 100[/tex]
[tex]r = \dfrac{A}{A+1.25 \times { A( 100-p)}} \times 100p[/tex]
[tex]r = \dfrac{100p}{p+125 -1.25 p}[/tex]
[tex]r = \dfrac{100p}{125 -0.25 p}[/tex]
multiplying both numerator and denominator by 4; we have
[tex]r = \dfrac{4(100p) }{ 4(125 -0.25) p}[/tex]
[tex]\mathbf{r = \dfrac{400p }{ 500 -p}}[/tex]

How many solutions does 10 + 5c = 5c
Answer:
No solutions
Step-by-step explanation:
Step 1: Write out equation
10 + 5c = 5c
Step 2: Subtract 5c on both sides
10 + 5c - 5c = 5c - 5c
10 ≠ 0
Since 10 doesn't equal 0, we do not have a solution for this equation.
Answer:
no solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
10+5c=5c
Step 1: Simplify both sides of the equation.
5c+10=5c
Step 2: Subtract 5c from both sides.
5c+10−5c=5c−5c
10=0
Step 3: Subtract 10 from both sides.
10−10=0−10
0=−10
Answer:
There are no solutions.

Ms. Ironperson lives due east from the shawarma mediterran grill and Mr. Thoro lives due south. Both leaves at the same time, ms.Iron person traveling at 50 mph and mr. Thoro at 60 mph. Calcute when they would be 400 mphs apart and how long would it take to happen
Correct question is;
Ms. Ironperson lives due east from the shawarma mediterran grill and Mr. Thoro lives due south. Both leaves at the same time, ms.Iron person traveling at 50 mph and mr. Thoro at 60 mph. Calculate when they would be 400 miles apart and how long would it take to happen
Answer:
They will be 400 miles apart when Ms. Ironperson has covered 256 miles and Mr. Thoro has covered 307 miles after 5.12 hours
Step-by-step explanation:
Since Ms. Ironperson lives due east from the shawarma mediterran grill and Mr. Thoro lives due south,then the distance between them will be the hypotenuse of a right angle triangle.
Now, we are told that Ms. Ironperson is traveling at 50 mph and that Mr. Thoro is traveling at 60 mph.
Thus, if we want to find when they would be at 400 miles apart, it means we have to find the distance Ms. Ironperson and Mr. Thoro would have covered after a time "t".
Thus,
Ms. Ironperson covered 50t miles
Mr. Thoro covered 60t miles
Therefore, since their location forms a right angled triangle, then we can use pythagoras theorem and we have;
(50t)² + (60t)² = 400²
This gives;
2500t² + 3600t² = 160000
6100t² = 160000
t² = 160000/6100
t = √(160000/6100)
t ≈ 5.12 hours
Thus, for Iron person, distance covered is: 50 × 5.12 = 256 miles
For Mr. Thoro, distance covered is: 60 × 5.12 ≈ 307 miles.
They will be 400 miles apart when Ms. Ironperson has covered 256 miles and Mr. Thoro has covered 307 miles after 5.12 hours
The elevation at Mt. Everest is 29,028 feet. The elevation of the Dead Sea is -485 feet. What is the difference in the elevation between Mt. Everest and the Dead Sea
helppppppppppppppppppppppppppp brainliest!!!
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
r = [tex]\frac{5}{8}[/tex] t - 9 ← is in slope- intercept form
with y- intercept c = - 9
Function 2 has the ordered pair (0, - 9 )
This indicates that when t = 0 , r = - 9
This is the y- intercept at - 9
Thus both functions have the same y- intercept

Camden is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 5 points. What would be Camden’s test score out of 50 if he got 2 questions wrong? What would be his score if he got x questions wrong
Answer:
1. 40 points2. 50-x pointsStep-by-step explanation:
1. Given that the total number of points is 50
2. Each question is worth 5 points
We can now calculate the number of questions by dividing the total points by the worth of each question
the number of question is = 50/5= 10
hence there are 10 questions available
if he misses 2 questions, which will amount to 10 points his score will be
50-10 = 40 points
Hence if he got x questions wrong his score will be
50-x points
