Answer:
A: Yes, I agree. Why? Because if you look at the shape, its a triangle right, and a triangle both sides are equal, while the bottom line is not. But because both sides are equal, and half of the triangle is MPN and the other side is QPN, they both are congruent (or equal to)
B: Like I said, both MPN and QPN are both equal, and if you remove the P, it would still be the same because the shape has not changed.

A textbook store sold a combined total of 236 history and physics textbooks in a week. The number of history textbooks sold was three times the number of physics textbooks sold. How many textbooks of each type were sold
Answer:
Step-by-step explanation:
Let H and P represent the number of history and physics textbooks.
We are told that:
1) H + P = 236/week, and
2) H = 3P [A disgrace, but that's a different problem]
We can substitute the definition of H in the second equation into the first:
H + P = 236/week
3P + P = 236/week
4P = 236
P = 59
H = 3P, so H = 3*(59) or 177
59 Physics and 177 History books for a total of 236 books sold that week.
A rental car agency charges $220.00 per week plus $0.25 per mile to rent a car. How many miles can you travel in one week for $380.00?
40 miles per week
Step-by-step explanation:
380-220 = 160÷4 = 40
You can travel 320 miles in one week for $320 miles.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
A rental car agency charges $220.00 per week plus $0.25 per mile to rent a car.
If the amount is $380.
Then, 380 - 220 = 160
And 160 divided by 0.5,
= 160/0.5
= 320 miles.
Therefore, the required distance is 320 miles.

Answer:
a = 45°
Step-by-step explanation:
In triangle PSR
PS = RS (Given)
angle SPR = angle SRP (isosceles triangle property)
Let angles SPR and SRP be x
Therefore, 90° + x + x = 180° (angle property)
=> 90° + 2x = 180°
=> 2x = 180° - 90° = 90°
=> 2x = 90°
=> x = 90° ÷ 2 = 45°
=> x = 45°

Answer:
it is not proportional. when you graph it, you will see it is not linear.
Step-by-step explanation:
Answer:
not proportional
Step-by-step explanation:
A graph that’s proportional would have to be linear a straight line but that cannot happen since the numbers are proportional
Its constant of proportionality is 12 and 10 so it could not work.
If two line are perpendicular which statement is true
I don't get this. (write a linear function f with the given values)
Answer:
f(x) = (1/2)x
Step-by-step explanation:
f(x) = mx + b
m is the slope
b is the y-intercept
m = rise/run
for every run of 2 in x
f(x) rises 1
m = 1/2
The y-intercept occurs when x = 0
from the table f(0) = 0
b = 0
Therefor
f(x) = (1/2)x + 0
f(x) = (1/2)x
Answer:
[tex]f(x) = 1/2*x[/tex]
Step-by-step explanation:
Linear functions are functions of the form "f(x) = a * x + b" where 'a' and 'b' are constants (numbers) and x is the input.
In this problem, you are given the inputs and outputs of the function. Since you know it is linear, you begin thinking about what number you can multiply on the left to get the value on the right.
-4 / 2 = -2
-2 / 2 = -1
0 / 2 = 0
We find that dividing x by 2 gives the correct output. Dividing by 2 is the same as multiplying by 1/2. Therefore, we have found the answer!
f(x) = 1/2 * x
