The value of the f(7) is -3 if the function is f(x) = x – 10 after plugging x = 7 in the function.
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.
We have a function:
f(x) = x -10
The above function represents the linear function.
To find the value of f(7) plug x = 7 in the function.
f(7) = 7–10
f(7) = -3
Thus, the value of the f(7) is -3 if the function is f(x) = x – 10 after plugging x = 7 in the function.

Answer:
is the answer 7ft?
Step-by-step explanation:
i am not completely sure
Set up a ratio of the height over the distance to the mirror/
X/5 = 28/7
Cross multiply:
7x = 140
7? = 140
Divide both sides by 7
? = 140/7
? = 20
The answer is 20 feet
Wil has a coin collection and is currently adding 9 coins per day to his existing number of coins in his collection.After 22 days he has a total of 218 coins. How many coins will he have after 36 days?
Answer:
344
Step-by-step explanation:
Number of coins added per day in the collection = 9
Number of coins in the collection after 22 days = 218
To find:
Number of coins in the collection after 36 days.
Solution:
First of all, let us find how many coins did he have initially.
Let the number of coins present initially with Wil = [tex]x[/tex]
Number of coins added per day = 9
Number of coins added after 22 days = 22 [tex]\times[/tex] 9 = 198
Therefore,
[tex]x + 198 = 218\\\Rightarrow x = \bold{20}[/tex]
Number of coins present with Wil initially = 20
Number of coins added after 36 days = 36 [tex]\times[/tex] 9 = 324
Total number of coins after 36 days = Number of coins present initially with Will + Number of coins added = 324 + 20 = 344

Write the equation of the line that is perpendicular to y = 3x - r and that has the same y - intercept .
WILL MARK BRAINLIEST
Answer:
y= -(1/3)x -r
Step-by-step explanation:
a perpendicular line has the slope of the line that it's perpendicular but its the negative reciprocal of it. So for ex: line 1 = 2x then the line perpendicular to it is -1/2x.
In this case, the slope is 3x. The line perpendicular to it therefore, should be -1/3x.
The problem states the line has the same y-intercept so it has to still be -r.
So the equation of the line perpendicular to y=3x-r with the same y-intercept is y=-(1/3)x -r

What is 72 Divided by 2= ??
Answer:
72 / 2 = 36
Step-by-step explanation:
Look at 7 first and figure out how many times 2 will go into 7. 2 will only go into 7 three times. (2 x 3= 6) So put 3 at the top of your division problem and subtract 6 from 7. You should get 1. Then, bring down your 2 to make that one a 12. How many times will 2 go into 12? 6 times. 6 x 2 equals 12 so put 6 at the top of your division problem next to that 3. Subtract your 12 from 12 to get 0. Your final answer would be 36.
Hope this helped!
The division of 72 and 2 is 36.
What is the division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
The given numbers are 72 and 2.
72 divided by 2
Here, 72/2
Where, 72 is dividend and 2 is divisor.
72/2 = 36
So, quotient is 36

A right triangle is ____ a scalene triangle.
Always, sometimes, or never
Answer: Sometimes
Step-by-step explanation:
This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas

What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know vertically opposite angles are of equal measure.
∴ m∠2 is 42°.
We know the sum of all the interior angles in a triangle is 180°.
∴ m∠1 = 180° - 50° - 42°.
m∠1 = 88°.
m∠3 = 180° - 42° - 25°.
m∠3 = 113°.

Step-by-step explanation:

Use the distributive property to multiply 3 by x−4.
3x−12=15x
Subtract 15x from both sides.
3x−12−15x=0
Combine 3x and −15x to get −12x.
−12x−12=0
Add 12 to both sides. Anything plus zero gives itself.
−12x=12
Divide both sides by −12.
