Answer:
2y +3 = 4y +2
Step-by-step explanation:
The left side shows 2y +3.
The right side shows 4y +2.
The scale is shown in balance, so we must have ...
2y +3 = 4y +2 . . . . equation from the model
__
The solution can be found by subtracting 2y+2 from both sides to leave ...
1 = 2y
Then we can divide both sides by 2 to find what y stands for:
1/2 = y . . . . solution to the equation

See below and attachedStep-by-step explanation:
1. There are infinite number of lines going from only one point (2, 5)
No definite solution for line A.2. This is a proportional relationship, since line passes through the origin. The slope is -3.
The line B is:
y = -3x3. Points (-3, -2) and (3, 10)
The slope:
m = (10 + 2)/(3 + 3) = 2The y - intercept:
10 = 2*3 + b ⇒ b = 4The line C is:
y = 2x + 44. The rate of change is m = 2.5
The y- intercept:
1 = 2*2.5 + b ⇒ - 4The line D is:
y = 2.5x - 45. Line E has a slope of 4, no sufficient info to conclude.
y = 4x + b, with any value of b6. Line F has m = -3/4 and passes through (8, -1).
The y -intercept is:
-1 = 8(-3/4) + b ⇒ b = 5The line F is:
y = -3/4x + 57. G is not a linear relationship as the function increases exponentially with common ratio of 3.

Its 15 because if the decimal after the whole number is less than 0.5 you go to the closest whole number down. Meaning whatever the whole number is attached to your decimal lower than 0.5 is your answer. If it's higher than 0.5 or IS 0.5 you round the nearest whole number, so one bigger than the number attached to your decimal. So if it was say:
15.67
The nearest whole would be 16

2xy-yz=8 solve for z
Answers
The solution of the equation in terms of z will be; z = 2x - 8/y
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given the equation as;
2xy-yz=8
Now we have to solve for z;
2xy-yz=8
-yz = 8 - 2xy
Then divide by y on both sides;
z = 2xy/y - 8 / y
z = 2x - 8/y

Please help i will give 100 points
Answers
First:
X = 15
Step-by-step explanation:
So the two angles are congruent, or they are the same angle. So you write the equation as 5x + 9 = 84.
5x + 9 = 84
-9 -9
5x = 75
(divide) 5 from both sides
x = 15
Second:
X = 27
Step-by-step explanation:
For this one I believe the answer is X = 27 because both equations should equal 180 degrees.
So you write the final equation:
(x + 72) + (3x) = 180
-72 -72
(combine X's):
4x = 108
Divide both sides by 4
X = 27
Third:
X = 40
Step-by-step explanation:
For this one, the angles match again, so you write it s:
4x - 50 = 2x + 30
+50 +50
4x = 2x +80
-2x -2x
2x = 80
Divide both sides by 2
X = 40
