Answers
Answer:
x = 12 ; m∠R = 130°
Step-by-step explanation:
(6x - 22)° + (8x + 34)° = 180°
6x - 22 + 8x + 34 = 180
14x + 12 = 180
14x = 168
x = 12
m∠R = (8x + 34)° = (96 + 34)° = 130°
m∠R = 130°

As one object gets closer to another object the force of gravity will increase?
Answers
Answer:
no
Step-by-step explanation:
gravity is relevant to when something is being affected by the gravitational pull on earth, or any other planet. for example, i throw an apple into the air. and it comes back down, as newton said. what must come up, must come down. because of gravity, two objects being closer together does not affect the gravitational pull whatsoever. and the force of gravity doesn't change. as gravity just works on it's own, independent of the object, not dependent on the object. however certain objects will fall abit faster than others.

Given functions f and g, Find f-g.
f(x)=6x-2, g(x)=9x-6
a)3x-4
b)-3x+4
c)-3x-8
d)15x-8
Answers
Answer:
b)-3x+4
Step-by-step explanation:
f(x)=6x-2, g(x)=9x-6
f - g means to subtract the two functions so:
f - g = (6x - 2) - (9x - 6)
first, distribute the negative sign to (9x - 6)
f - g = 6x - 2 - 9x + 6
then, combine like terms:
f - g = -3x + 4
Factor to write an equivalent expression for -9x+15y
Answers
Answer:
Step-by-step explanation:
-9x +15y = 3(-3x +5y) = -3(3x - 5y)
The required equivalent expression for the given expression -9x + 15y is 3(-3x + 5y).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
The given expression is given as follows:
-9x + 15y
It is required to find the factorization of the given expression.
As per the question, we have
-9x + 15y
To factor -9x + 15y, we can first factor out the greatest common factor (GCF) of -9 and 15, which is 3:
-9x + 15y = 3(-3x + 5y)
Therefore, the equivalent expression for -9x + 15y is 3(-3x + 5y).

B) Give the slope and y- intercept.
C) Use the slope and y -intercept to the graph the linear function.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptPart a)
Given the equation
[tex]9x-3y-9=0[/tex]
Writing the equation in the slope-intercept form of the line equation
[tex]9x-3y-9=0[/tex]
adding 3y to both sides
[tex]9x-3y-9+3y=0+3y[/tex]
[tex]9x-9 = 3y[/tex]
flip the equation
[tex]3y = 9x-9[/tex]
divide both sides by 3
[tex]y=3x-3[/tex]
Thus, the equation in the slope-intercept form is:
[tex]y=3x-3[/tex]
Part b)
As the equation in the slope-intercept form is
[tex]y=3x-3[/tex]
comparing with the slope-intercept form
The slope m = 3The y-intercept b = -3Part c)
Given the equation
[tex]y=3x-3[/tex]
The graph is attached below.
From the given graph, is clear that:
at x = 0, the value of y = -3
Thus, the y-intercept of the equation is b = -3

Why are inverse relationships between operations used to solve two step inequalities?
Answers
Answer:
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.
Reverse addition and subtraction (by subtracting and adding) outside parentheses. Reverse multiplication and division (by dividing and multiplying) outside parentheses. When multiplying or dividing by a negative number, flip the inequality sign. It does not matter if the number being divided is positive or negative
It's necessary to apply inverse operations on both sides of the equals signs so that you can solve for the variable and balance the equation.
Multi-step inequalities are solved using the same processes that work for solving equations with one exception. When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol. (Much like when you divide by a negative number, the sign of the inequality must flip! Here's why: When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!)
