Here are a few pieces of advice that will help you and your math skills:
- Take notes. Taking notes during your math classes will help you remember key points and formulas. If you were to ever forget, for example, the quadratic formula, by writing it down you can always reference back to your notes for the quadratic formula.
- Practice! Nobody gets everything right the first time. By practicing and doing the math over and over, you will improve your skills and will better remember them.
- Ask! Don't be afraid to ask for help. Brainly is designed to help people on certain questions and subjects that they struggle with, including math. So you can always ask us. You can ask your teachers, your peers, and your family as well.
5.
-4n+ 7+ 2n= 1
⇒ (-4n+ 2n)+ 7= 1 (combine like terms)
⇒ -2n= 1-7
⇒ -2n= -6
⇒ n= -6/(-2)
⇒ n= 3
Final answer: B. 3~
6. 4(y-4)= 8
⇒ y-4= 8/4
⇒ y-4= 2
⇒ y= 2+4
⇒ y= 6
Final answer: D. 6~
Answer:
y = -
x - 7
Step-by-step explanation:
Parallel lines have equal slopes.
Calculate the slope m of the given line using the slope formula
m = 
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line
m =
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute P(- 3, - 3) into the partial equation
- 3 = 4 + c ⇒ c = - 3 - 4 = - 7
y = -
x - 7 ← equation of parallel line
Answer:
The correct option is C) 
Step-by-step explanation:
Consider the provided information.
A farmer charges $6 for 4 pounds of tomatoes.
First find the unit rate as shown below:

Therefore, the cost of 1 pound of tomatoes is $1.5
let d represents the dollars he should charge and p represent the pounds of tomatoes farmer sold.
Thus the required equation is 
Hence, the correct option is C)
