ZA and ZB are supplementary angles. If m_A= (5x + 25)° and m
ZB = (3x + 19)°, then find the measure of ZB.
Answers
Answer:
B = 70
Step-by-step explanation:
Supplementary angles add to 180
5x+25 + 3x+19 = 180
Combine like terms
8x+ 44 =180
Subtract 44 from each side
8x+44-44 =180-44
8x= 136
Divide by 8
8x/8 = 136/8
x = 17
We want to find B
B = 3x+19 = 3(17)+19 = 51+19 = 70

Assuming you want x to approach negative infinity, you have the correct answer. It is choice A.
=====================================================
Explanation:
The root x = -2 leads to the factor x+2. That means the answer is between A and B.
As x approaches negative infinity, i.e. as we move to the left, we're going down the red curve and y = f(x) is going to approach negative infinity as well.
In terms of symbols, we'd write [tex]x \to -\infty, \ f(x) \to -\infty[/tex]
Informally, we could say "it falls to the left" as a way to describe this left end behavior.

Rotate the vector (0,2) 270 degrees counterclockwise about the origin
Answers
Explanation:
The vector (0,2) points directly north and the length of this vector is 2 units. It's the distance from (0,0) to (0,2).
When rotating 270 degrees counterclockwise, we'll turn to the left or westward direction (90 degrees so far) then at some point aim directly south (180 degrees so far) and finally ultimately end up pointing directly east (after getting to 270). So that's how we go from (0,2) to (2,0).
If you were to go clockwise, then everything flips and you'll ultimately end up pointing directly west. The length of the vector stays the same the whole time.
The coordinates of the vector (0,2) after 270° counterclockwise rotation about the origin is (2,0), as shown below.
What is coordinate?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
The coordinates of the vector (0,2) after 270° counterclockwise rotation about the origin is (2,0), as shown below.

Answer:
B B C C A A
Step-by-step explanation:
If we number the equations 1 to 6 left to right, then we have ...
B - can be put (y = 2x)B - can be put (y = (1/9)x)C - other, not a proportional relationshipC - other, y = 5/x, an inversely proportional relationshipA - has the form, k = 0.04A - has the form, k = -111-5. Graph MU (line MU) for M(-1, 1). (Look at the bottom of the pic)
Answers
a) The slope of the line MU is [tex]\frac{4}{5}[/tex]
b) The distance between the coordinates of the line MU is √41
c) There are differences and similarities between (a) and (b).
The slope of a line is used to describe how steep the line is. This is expressed mathematically as;
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where:
(x1, y1) and (x2, y2 are the coordinate points)
From the graph shown, we are given the coordinates M(-1, 1) and U(4, 5)
a) The slope of the line MU will be expressed as;
[tex]m=\frac{5-1}{4-(-1)}\\m=\frac{4}{5}[/tex]
The slope of the line MU is [tex]\frac{4}{5}[/tex]
The formula for calculating the equation of a line is expressed as y = mx + b
b is the y-intercept.
Substitute m = 4/5 and (-1, 1) into the expression y = mx + b
[tex]1 = -(4/5) + b\\1 = -4/5 + b\\b = 1 +4/5\\b = \frac{5+4}{5} \\b = \frac{9}{5}[/tex]
Get the required equation.
Substitute m = 4/5 and b = 9/5 into y = mx + b
[tex]y=\frac{4}{5}x+\frac{9}{5}\\5y=4x+9\\5y-4x=9[/tex]
The required equation of the line is 5y - 4x = 9
b) The formula for calculating the distance between two points is expressed as;
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute the given coordinates in (a) to get the distance MU
[tex]MU=\sqrt{(4-(-1))^2+(5-1)^2}\\MU=\sqrt{(4+1)^2+(5-1)^2}\\MU=\sqrt{(5)^2+(4)^2}\\MU=\sqrt{25+16}\\MU=\sqrt{41}[/tex]
Hence the distance MU is √41
c) There are similarities and differences in the calculations in (a) and (b). The similarities lie in the usage of the change in the coordinates for the calculation of the slope and the distance.
The difference is that we do not need the slope of the line to calculate the distance MU but the slope y-intercept is required to calculate the equation of the line.

Kurt simplifies this equation and says the
solution is x = 7. What can you tell Kurt
about his work?
3(x-7)=2x - 14
3x - 7 = 2x - 14
x=-7
Answers
He made an error on the second line. Kurt didn't distribute the 3 to each term inside the parenthesis of (x-7)
3(x-7) does not turn into 3x-7. Instead, it should be 3x-21 because 3*7 = 21.
This is what his steps should look like
3(x-7) = 2x - 14
3x - 21 = 2x - 14
3x-2x = -14+21
x = 7
