Answer:
perhaps because math is a subject that builds on itself. so if you miss or dont know one key formula then it is difficult to understand the others.
math is also a subject that has many different ways to solve one thing
if f(x)=x-4 find the value if f(x)+f(-x)
Answer:
2x
Step-by-step explanation:
f(x) = x -4
Step 1:
y = x - 4
Step 2: Replace y with x
x = y - 4
Step 3: Find y
x + 4 = y
f(-x) = x + 4
f(x) + f(-x) = (x - 4)+ (x + 4) = 2x

Find the measure of the angle indicated in bold (7x + 10)
Also can you explain how you got the answer
Answer:
80°
Step-by-step explanation:
8x = 7x + 10
They are alternate(different sides of the intersecting or transversal line) interior(inside the two parallel lines)angles
alternate interior angles
8x = 7x + 10
x = 10
7(10) + 10 = 80

Ms. Johnson bought an area rug for her den. The perimeter is 30 feet. The width of the rug is
2yards What is the area of Ms. Johnson's rug in square feet and square yards?
in both feet and yards.
Answer:
6 sq yards, 54 sq feet
Step-by-step explanation:
30/3 = 10, 10 - 4 = 6, 6/2 = 3, 3 * 2 = 6
30/3 since we are calculating yards(3 ft = 1 yard), 10 -4 since 2 sides have the width of 2 yards. 6/2 since there is two sides left.
Basically the same thing for sq feet.
a bank account balance for an account with an initial deposit of p dollars earns interest at an annual rate of r . the amount of money in the account after n years is described using the following expression p (1+r)n what effect if any does decreasing the value of r have on the amount of money after n years?
Answer:
Step-by-step explanation:
For the same exponent n and 1 < a < b we have
[tex]a^n < b^n[/tex]
Now if we decrease the r the value then 1 + r will also decrease.
If follows that the amount of money after n years will also decrease.

Malcom has $638.54 in his checking account. He must maintain a $500 balance to avoid a fee. He wrote a check for 159.50 today. Write an inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee.
(9th grade Algebra 1)
The inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee is 638.54 - 159.50 + x ≥ $500
The given parameters:
initial amount of money in Malcom's account = $638.54
a constant balance to be maintained to avoid a fee = $500
amount to be withdrawn today = $159.50
To find:
inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a feeLet the LEAST amount = x
Here are basic things to note in order to form the equation:
The money going into the account must be addedThe amount to be withdrawn will be subtracted Finally, the total amount must be greater or equal to $500Considering the above explanation, the inequality becomes;
638.54 + x - 159.50 ≥ $500
Rearrange to match the given options;
638.54 - 159.50 + x ≥ $500
Thus, the inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee is 638.54 - 159.50 + x ≥ $500

Answer:
∠LMP = 77
∠NMP = 103
Step-by-step explanation:
to find the measure of ∠LMP and ∠NMP
we know that ∠LMN is a straight line so that will be 180 degrees
so you can say that
∠LMP + ∠NMP = 180
(-16x +13) + (-20x +23) = 180
-16x +13 -20x + 23 = 180
-36x + 36 = 180
-36x = 180-36
-36x = 144
x = 144/-36
x = -4
∠LMP = (-16x +13)
= ( -16 (-4) + 13)
= ( 64 + 13)
= 77
∠LMP = 77
∠NMP = (-20x +23)
= (-20 (-4) + 23)
= 80 + 23
= 103
∠NMP = 103

Answer:
1. You should mix 5 cups of yellow paint with 1 cup of blue paint. The table shows that the ratio is 1:5 (blue:yellow) so 1 cup of blue paint means you need 5 cups of yellow paint.
2. Using the same ratio (1:5), you can multiply both numbers by any number and get the same shade of green.
5 cups of blue paint will need 25 cups of yellow paint.
(1 x 5 = 5 : 5 x 5 = 25)

Convert 19.3 picometers per squared kiloseconds (pm/ks^2) into megameter per squared nanoseconds (Mn/ns^2).
Unit conversion involves the conversion of a metric unit to another unit of the same quantity.
[tex]19.3 pm/ks^2[/tex] to megameter per squared nanoseconds is [tex]19.3 \times 10^{-41} Mn/ns^2[/tex]
Let:
[tex]x = 19.3 pm/ks^2[/tex]
Multiply by [tex]10^{-17[/tex] to convert megameter per squared kiloseconds
[tex]x = 19.3 \times 10^{-17} Mn/ks^2[/tex]
Divide by [tex]10^{24[/tex] to convert to megameter per squared nanoseconds
[tex]x = \frac{19.3 \times 10^{-17}}{10^{24}} Mn/ns^2[/tex]
Apply law of indices:
[tex]x = 19.3 \times 10^{-17-24} Mn/ns^2[/tex]
[tex]x = 19.3 \times 10^{-41} Mn/ns^2[/tex]
Hence:
[tex]19.3 pm/ks^2[/tex] to megameter per squared nanoseconds is [tex]19.3 \times 10^{-41} Mn/ns^2[/tex]
