General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Function NotationStep-by-step explanation:
Step 1: Define
h(x) = 4x² - 5x
h(-3) is x = -3
Step 2: Evaluate
Substitute in x: h(-3) = 4(-3)² - 5(-3)Exponents: h(-3) = 4(9) - 5(-3)Multiply: h(-3) = 36 + 15Add: h(-3) = 51Answer:
f(-3) = 51
Step-by-step explanation:
f(x) = 4x^2 - 5x
f(-3) = 4(-3)^2 - 5(-3)
f(-3) = 4*9 - (-15)
f(-3) = 36 + 15
f(-3) = 51

I have two questions. Both need written in standard form. Please show your work!!
1.) What is : y= 1/5x + 1/3 in standard form?
2.) What is : y= 2/7x - 1/3 in standard form?
Answer:
1) 3x - 15y = 5
2) 6x - 21y = 7
Step-by-step explanation:
standard form: Ax + By = C
1) y = 1/5x + 1/3
multiply each side by 15 to eliminate fractions: 15y = 3x + 5
final form: 3x - 15y = -5
2) y = 2/7x - 1/3
multiply each side by 21 to eliminate fractions: 21y = 6x - 7
final form: 6x - 21y = 7

The price of an item has been reduced by 60% the original price was $20 what is the price of the item now
Answer:
6
Step-by-step explanation:
20 times 0.3 is 6
Answer:
reduced by 20% so that means it is going to be 20% cheaper. You need to take off 20% of $60
20% is 0.2
of in math ALWAYS means multiply
0.2 X 60 = 12
You get 12 off
60 - 12 = 48
the new price is $48.00
Here is another way. You get 20 % off and that leaves 80% that you have to pay.
80% of 60
= 0.8 x 60
= 48
You pay $48.00
Step-by-step explanation:

Gonzalo is trying to find the unit price On a 6-pack of orange juice on sale for $6.99. His sister says that at that price, each bottle of orange juice would cost over $1.05. Is she correct?
Answer:
Yes
Step-by-step explanation:
Unit prices come from dividing the price, $6.99, by the amount of product, 6,
6.99 ÷ 6 = 1.165
Now, because you cannot have more than two digits in the cents part, you would round that up to $1.17 which is over $1.05 dollars per bottle.

Find the length of side x in simplest radical form with a rational denominator.
Answer:
x = 2√3
Step-by-step explanation:
The sides of a 30-60-90 triangle are always in the ratio 1:√3:2.
The length of the side opposite the 90° angle is 4, so the length of the side opposite the 30° angle is 2 and the length of the side opposite the 60° angle is 2√3.
x = 2√3

X
500
Answer:
88.16
Step-by-step explanation:
You will have to use tan to solve it
The value of x round to the nearest tenth is,
⇒ x = 85
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
Base of height = 500
Angle = 10°
Now, We can formulate;
⇒ tan 10° = x / 500
⇒ 0.17 = x / 500
⇒ x = 85
Thus, The value of x round to the nearest tenth is,
⇒ x = 85
