Step-by-step explanation:
there seems to be something missing.
I assume the slope of the line is -2/3.
the slope of a line is always the factor of x in the equation.
the slope is the y/x ratio indicating how many units y changes, when x changes by a certain amount of units (e.g. when going from one point on the line to another).
the equation for the line looks like this then :
y = (-2/3)×x + b
to get b we use the provided point (-6, -5) and it's x and y values.
-5 = (-2/3)×-6 + b = 4 + b
b = -9
so, the full equation of the line is
y = (-2/3)×x - 9

Answer:
25.75
Step-by-step explanation:
mean=sum of all numbers/number of numbers given
we have 4 numbers given 28,20,30 and 25
mean=28+20+30+25/4
mean=103/4
mean=25.75 :)

Answer:
<ABC = 70 degrees
<AMC = 60 degrees
< AMB = 60 degrees
Step-by-step explanation:
<ABC = 180-110 = 70 degrees
<AMC = 2x + 60 = 180
2x = 180 - 60
x = 120/2
x = 60
<AMB = 180/3 = 60

find the decimal equivalent of ¾ ounce to the thousandths place
0.75
Explanation:
Every 1/4 is 25. If you want to calculate them, then you're going to need 1/4 to find 25. In some other cases, 25, can also be written as another decimal. Such as, 4/100.
100/4 is 25. For example:
Woah! You have 3/4 of a dollar. You're really saving up money fast!
This example means that the person has 75 cents.
For an ounce, that would mean 0.04 pounds.

O A) x^2 + y^2 + 12x - 20y+ 132 = 0
-
O B) x^2 + y^2 + 12x - 20y + 55 = 0
-
O C) x^2 + y^2 - 12x+ 20y + 127 = 0
-
O D) x^2 + y^2 – 20x – 16y + 155 = 0
Answer:
C.
Step-by-step explanation:
WE need to convert the given equations into the standard form
(x - a)^2 + (y - b)^2 = r^2 where r = the radius.
x^2 + y^2 + 12x - 20y+ 132 = 0
(x + 6)^2 - 36 + (y - 10)^2 - 100 = -132
(x + 6)^2 + (y - 10)^2 = -132 + 36 + 100 = 4
giving a radius of 2
x^2 + y^2 + 12x - 20y + 55 = 0
will give a right hand side of -55 + 36 + 100 = 81 giving radius 9.
x^2 + y^2 - 12x+ 20y + 127 = 0
- gives right hand side of -127 + 36 + 100 = 9 giving a radius of 3.
Answer:
The answer is C I hope this helps
Solve the inequality. Graph the solution
Answer:
1. y > -3/5 and y < 7/5 Direction to graph 1 below.
2. r > 1 and r < 13/3 Direction to graph 2 below
Step-by-step explanation:
|5y - 2| + 5 > 0
Case 1 Positive || Case 2 Negative ||
5y - 2 + 5 > 0 -(5y - 2) + 5 > 0
5y +3 > 0 -5y + 2 +5 > 0
5y > -3 -5y + 7 > 0
y .> -3/5 -5y > -7
-y > -7/5
y < 7/5 y value negative, change sign
The graph 1: open circle at -3/5; close circle at 7/5; shade between these two numbers.
2. |8-3r|< 5
Case I Case II
8 - 3r < 5 -(8-3r) < 5
-3r < 5 - 8 -8 + 3r < 5
-3r < -3 3r < 5 + 8
-r < -3/3 3r < 13
r >1 r is negative, change r < 13/3
the direction of the sign
Graph 2: Open circle at 1; open circle at 13/3; shade between the two numbers.

x = -15/2
3 (1 - 3x) = 2 (- 4x +7)
Answer: x = -11
Step-by-step explanation:
Expand the expression (distributive property): 3 - 9x = -8x + 14
// subtract 14 from both sides = -11
// add 9x on both sides = x
Simplify: x = -11
Answer:
[tex]x=-11[/tex]
Step-by-step explanation:
1) Rearrange Terms
[tex]3(-3x+1)=2(-4x+7)[/tex]
2) Distribute
[tex]-9x+3=2(-4x+7)[/tex]
3) Distribute
[tex]-9x+3=-8x+14[/tex]
4) Subtract 3 from both sides of the equation
[tex]-9x+3-3=-8x+14-3[/tex]
5) Simplify
A. Subtract the numbers
[tex]-9x=-8x+14-3[/tex]
B. Subtract the numbers
[tex]-9x=-8x+11[/tex]
6) Add 8x to both sides of the equation
[tex]-9x+8x=-8x+11+8x[/tex]
7) Simplify
A. Combine like terms
[tex]-x=-8x+11+8x[/tex]
B. Combine like terms
[tex]-x=11[/tex]
8) Divide both sides of the equation by the same term
[tex]\frac{-x}{-1} =\frac{11}{-1}[/tex]
9) Simplify
A. Cancel terms that are in both the numerator and denominator
[tex]x=\frac{11}{-1}[/tex]
B. Divide the numbers
[tex]x=-11[/tex]
Jorge has a standard deck of 52 cards and a six-sided number cube. What is the probability that he will draw a diamond from the deck of cards and roll a number greater than two? Write your answer as a simplified
The probability that Jorge draw a diamond from the deck of cards and roll a number greater than two is 2/39
Probability is the like likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
If Jorge has a standard deck of 52 cards, the total outcome is 6
If Jorge draw a diamond card, the probability that he will draw a diamond card is 4/52 = 1/13
For a six-sided cube, the total outcome is 6. If he rolls a number greater than two, the expected outcome will be 4
The probability that he rolls a number greater than 2 is 4/6 = 2/3
The probability that Jorge draw a diamond from the deck of cards and roll a number greater than two is 1/13 * 2/3 = 2/39

Answer:
Both of them are correct.
Step-by-step explanation:
Both of them are correct.
EQ. 1) y = -2x + 3
EQ. 2) 6x + 3y = 9
Transform EQ. 2 into its slope-intercept form, y = mx + b:
6x + 3y = 9
6x - 6x + 3y = -6x + 9
3y = -6x + 9
3y/3 = (-6x + 9)/3
y = -2x + 3 (As you can see, Equation 2 is equivalent to Equation 1's).
Given that Equations 1 and 2 are equivalent, their lines will coincide on top of each other (as if they're the same line) once graphed.
Therefore, the systems of linear equations will have infinitely many solutions.
Let's see why Charles and Destiny are both correct with their claims.
If you plug in Charles' coordinates (3, -3) in both equations,
EQ. 1) y = -2x + 3
-3 = -2(3) + 3
-3 = -6 + 3
-3 = -3 (True statement)
EQ. 2) 6x + 3y = 9
6(3) + 3(-3) = 9
18 - 9 = 9
9 = 9 (True statement)
Do the same thing for Destiny's coordinates: (-1, 5)
EQ. 1) y = -2x + 3
5 = -2(-1) + 3
5 = 2 + 3
5 = 5 (True statement)
EQ. 2) 6x + 3y = 9
6(-1) + 3(5) = 9
-6 + 15 = 9
9 = 9 (True statement)
With these calculations, it shows that both of their coordinates are solutions to the given systems of linear equations.

Answer:
Step-by-step explanation:
6) y = 2x² + 6x - 80
1) y = 2*x² + 2*3x - 2*40
y = 2 [ x² + 3x - 40]
2) Sum = 3
Product = -40
Factors = (-5) ; 8 {-5 +8 = 3 ; (-5)*8 = -40}
y = 2 [ x² + 8x - 5x - 40]
= 2 [ x(x + 8) - 5(x + 8) ]
= 2 [ (x +8) (x - 5)]
y = 2(x +8)(x -5)
b) y = 0
2(x + 8)(X - 5) = 0
x + 8 = 0 ; x - 5 = 0
x = -8 ; x = 5
(-8) ; 5 are the zeros.
