Answer:
1. 9x+4<58
x<6
2. 1x-2>3
x>1
Step-by-step explanation:
1. 9x+4<58
First, you need to group all the like terms ( the group of numbers that have the same variable), Also remember that, when a positive number crosses an inequality symbol, it becomes negative.
9x<58-4
Then, subtract the two numbers.
9x<54
Divide x's coefficient by 54 and you have your answer.
x<6
2. 1x-2>3
First, you need to group all the like terms. Remember that, when a negative number crosses an inequality symbol, it becomes positive.
1x>3-2
Then, subtract the two numbers.
1x>1
1 divided by one is one, so
x>1
Answer:
a
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = B(- 4, 2) and (x₂, y₂ ) = C(- 2, - 2)
m = 
= 
= - 2
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, - 2), then
- 2 = 4 + c ⇒ c = - 2 - 4 = - 6
y = - 2x - 6 ← equation of line through B and C
Answer:
8.48
Step-by-step explanation:
Your answer is B. twice v.
This is because if you were to write out 2v as an expression with its operations, it would be 2 × v, and if you are multiplying v by 2, then the result will be twice the value of v.
I hope this helps!
