write the slope - intercept form of the equation. PLEASE HELP. i will mark brainliest
Answers
Answer:
Step-by-step explanation: To find the equation of the perpendicular line, take the reciprocal of the slope with the opposite sign.
For example, the reciprocal of 4/3 is 3/4 and if it's negative, the opposite is positive.
The reciprocal of 2 is 1/2. and if it's positive, the opposite is negative.
The reciprocal of any number or fraction is whatever you multiply it by to get 1. 4 times 1/4 is 1 5/4 times 4/5 is 1. What about 1 ? 1 times 1 is 1. So one is its own reciprocal!

Use the substitution method to solve the system of equations.
2x + 3y = 12
y = x-1
A. (3, 4)
B. (0,4)
C. (3,2)
D. (2,3)
Answers
Answer:
(3,2)
Step-by-step explanation:
The solution to the system of equations is (3, 2). So, the answer is option C. (3,2).
How to solve the equations by substitution method?We are given the system of equations:
2x + 3y = 12
y = x-1
We can use the substitution method by substituting the expression for y in the first equation with the value of y from the second equation:
2x + 3(x-1) = 12
Simplifying the equation, we get:
2x + 3x - 3 = 12
5x = 15
x = 3
Now, we can substitute the value of x in either of the two equations to find the value of y:
y = x-1
y = 3-1
y = 2
Therefore, the solution to the system of equations is (3, 2). So, the answer is option C. (3,2).

Theresa volunteers at a food sheif. when she started, there were 213 oranges. After filling X bags of three oranges each, there were fewer than 51 oranges left. How many bags of oranges did Theresa fill?
Write an expression in terms of X for the number of oranges that Theresa bagged.
Part B: Write an expression in terms of X for the number of oranges that are left (have yet to be bagged).
Part C: Write an inequality using the expression from Part B to represent this scenario.
Part D: Solve the inequality for the variable X. Use opposite operations on both sides of the inequality until you get X on one side of the inequality by itself.
Part E: Did you have to flip the inequality sign? Explain why or why not.
Part F: What does the result from Part D tell you about Theresa's situation? Does the answer make sense? Explain.
Part G: Think about graphing the inequality you found in Part D on a number line. What would it look like?
Choose the correct number:
1. open circle on 54 and arrow pointing right
2. open circle on 54 and arrow pointing left
3. closed circle on 54 in arrow pointing right
4. closed circle on 54 and arrow pointing left
Answers
Answer:
A- The expression 3x represents the number of oranges that she bagged
B- 213 − 3x (or -3x + 213)
C- 213 − 3x < 51 (or -3x + 213 < 51)
D- x >54
E-Yes, I had to flip the inequality sign because I divided both sides of the inequality by a negative number (-3).
F- x > 54 means Theresa filled more than 54 bags of oranges. It makes sense because if Theresa made more than 54 bags of 3 oranges each, there would be fewer than 51 oranges left over.
G- Number 1 is correct.

Use this expression to name each item. 7m3 + 6r2 – 3r - 8
Answers
Answer:
In the given expression [tex]7m^3 + 6r^2 - 3r - 8[/tex]
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8
Step-by-step explanation:
We are given the expression [tex]7m^3 + 6r^2 - 3r - 8[/tex]
We need to give variable, coefficients and constant.
Variable: The value of variable may change. It can be represented by x, y or any other letter
Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient
Constant: It is fixed value. It cannot be changed.
So, in the given expression [tex]7m^3 + 6r^2 - 3r - 8[/tex]
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ √(x + 3) + 4 = 5
Now, We can solve the expression for x as;
⇒ √(x + 3) + 4 = 5
Subtract 4 both side, we get;
⇒ √(x + 3) + 4 - 4 = 5 - 4
⇒ √(x + 3) = 1
Taking square both side,
⇒ (√(x + 3))² = 1²
⇒ x + 3 = 1
Subtract 3 both side,
⇒ x + 3 - 3 = 1 - 3
⇒ x = - 2
