Answer:
[tex]d \: is \: correct[/tex]
Answer:
a. y = -2x-5
Step-by-step explanation:
*Don't get confused the y-axis scale is 2
I guess you would kind of have to guess by looking at the graph for this one, the y-intercept is 5.
The graph is negative because it is pointing the opposite way
The slope is 2 because the y-axis has a scale of 2
With these facts you can formulate that the equation would be y = -2x-5
Which of these u is a example

Answer:
C. Typing 28 words in 2/3 of a min
Step-by-step explanation:
42 words : 60 secs = ? words : ? secs
42:60 16:40 / This could not be an answer because 1/3 of 42 is 14. And 16 exceeds 14. So this couldn't be a possible answer choice.
42:60 16:80 / This could not be an answer because 16 is less than 42 and the time given here is over 60 secs.
42:60 28:40 / This would be an answer because 1/3 of 42 is 14. SO if we multiplied 14 by 2 we would be 28.
42:60 28:80 / This could not be an answer because 28 is less than 42 and the time given here is over 60 secs.
Is this correct now?

Answer:
y=1/2x - 2.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
We can use the point-slope formula to write an equation for this line. The point-slope formula states :
where m is the slope and (x1 y1) is a point the line passes through .
We can substitute the slope and values from the point to give:
(y-1) = 8 (x-7)
We can also transform this equation to the slope-intercept form by solving for
y
. The slope-intercept form of a linear equation is: y=mx+b
where the m is the slope and b s the y-intercept value.
y-1= (8 times x) - ( 8 times 7)
y-1= 8x - 56
y-1 + 1= 8x- 56 + 1
y-0= 8x- 55
y= 8x - 55

The answers are :
a) The graph is translated downwards by 4 units.
b) The graph is translated downwards by 2 units.
What do you mean by translation of a graph ?
The modification of an existing graph or graphed equation to create a different version of the following graph is known as translation.
a)
The graph of y = f(x) is shown.
The other function is y = f(x) - 4.
As it can be observed that the graph is translated from its parent function which is y = f(x) to function y = f(x) - 4.
The graph is shifted down by 4 units or translated downwards by 4 units.
b)
Here , the graph of y = g(x) is shown.
The other function is y = g(x -2)
As we can observe that the graph is translated from its parent function which is y = g(x) to function y = g(x - 2).
The graph is shifted downwards by 2 units or translated downwards by 2 units.
Therefore , the answers are :
a) The graph is translated downwards by 4 units.
b) The graph is translated downwards by 2 units.

Someone please HELP!!!

Answer:
Step-by-step explanation:
Question 1) Take each point and move down two units. For example: Take point A, keeping it on the vertical line, and count two squares down, then place a new point there and call it A1. Do the same for each point in the parallelogram. Question 2) Take one point from parallelogram EFGH and move it two squares to the left. Then from that new point, count four squares down and place a new dot there. Do this for every point in the EFGH parallelogram. Question 3) This one is a bit trickier. Ok, so we know three points on the graph. L(-5, -5), M(-5, -2), and N(-2, -2). Ok so we know that if we plot these points, they will make three points in a square. All we need is the fourth point. To get that, we have to place all three points on the graph. Let's start with L. The coordinates are (-5, -5). Now, the first number is -5 which means to go 5 points to the left from the center point, then the next number is -5 again, so that means that from that point that we just made, you go 5 points down, and then that is your point L. Now, for point M, it is the same thing except for the second number, it tells us to go -2. So, instead of going 5 down like the first point, you must go 2 points down after you have to the left 5 points. REMEMBER: when plotting points, you always have o start in the center point(center of the graph). Negative numbers are always left and down. Positive numbers are always right and up. Do the same thing for point N (left 2, and then 2 down). After you have plotted all three of these points, you can see that there is one point missing. The point that we are missing is (-2, -5) (2 to the left, and 5 down).Question 4) Ok, so what you want to do is first plot your points. X(2, 1): start at center point and go 2 points to the right and one point up. Y(4,4): from center point, o 4 points to the right and the 4 points up. Z(5,2): from center point, go 5 points to the right then 2 points up. Now, connect your dots and it should make a triangle. Now for the tricky part. They want us to move our triangle 4 points down. So, start with letter Y and simply count 4 points down from its original point and place the new dot there. The new coordinates to this new Y point should be: (4, 0) (4 to the right of the center point and 0 up or down) So, this point should be on the line. The reason it is still 4 to the right is because all we did was move the point down and not left or right. DO this with the other two points and you should get: X(2, -3) (2 to the right and 3 down from center point) and Z(5, 2) (5 to the right and 2 down from center point)Question 5) THE FIRST NUMBER IS ALWAS THE NUMBER ON THE HORIZONTAL LINE.I. the point is is moved 4 to the right of the center point and 2 down. So it is (4, -2)
P. This point is moved negative 4 (to the left) and down 3 . So it is: (-4, -3)
G. This point is moved 5 to the right and then up 2 which makes it (5, 2)
Q. This point is moved 6 to the right and 4 down which makes it (6, -4)
R. This point is moved 2 to the left and 2 up which makes it (-2, 2)
S. (6, 4)
J. (-2, -4)
U. (-5, 0)
H. (3, -1)
K. (-6, -5)

6. What is the value of x in the solution to the systems of linear equations shown below?
2x - 2y+z=3
5y-z= -31
x+ 3y + 2z = -21
Step-by-step explanation:
[tex]1) \: \: 2x - 2y + z = 3 \\ 2x = 3 + 2y - z \\ x = \frac{3 + 2y - z}{2} \\ \\ 2) \: \: \: not \: any \: \: \: x \: \: \: available \: \: \\ \\ 3) \: \: x + 3y + 2z = - 21 \\ x = - 21 - 3y - 2z[/tex]
Answer:
x= -5
Step-by-step explanation:
5y-z= -31, add z and 31 to both sides
5y+31 = z, substitute z in the other two given equations
2x - 2y+z=3
2x-2y +5y+31 = 3, combine like terms and subtract 31 from both sides
2x+3y = -28
x+ 3y + 2z = -21
x+3y +2(5y+31) = -21, distribute 2 over the addition parenthesis
x+3y +10y+62 = -21, combine like terms and subtract 62 from both sides
x+13y = -83
Now we have 2 equations with 2 variables x and y to solve
2x+3y = -28
x+13y = -83
Because we need to find x then from the first equation we can write that
3y = -2x-28, subtract 2x from both sides and the divide both sides by 3
y = (-2x-28)/3, substitute this in the second equation
x + [13(-2x-28)/3] = -83 , distribute 13 . over the subtraction parenthesis
(3x/3)+[(-26x - 364) /3= -83, find the common denominator
3x+[(-26x - 364) = -83*3 , cross multiply
3x -26x = -249 +364, add 364 to both sides
- 23x = 115, divide both sides by (-23)
x= -5

A plant was 4/5 meters tall. Then 1/2 meter was cut off. When the height of the plant was last measured it had grown back 1/10 meter. What was the height of the plant when it was last measured?
i need this quick plz
The new height of the plant when it was last measured is [tex]\frac{2}{5}cm[/tex] tall
The initial height of the plant is 4/5 meters tall
If 1/2 meter was cut off, hence the new height of the plant will be expressed as;
[tex]N_h=\frac{4}{5} -\frac{1}{2}\\N_h=\frac{2(4)+5}{10}\\N_h=\frac{8-5}{10}\\N_h=\frac{3}{10}[/tex]
Hence the new height is 3/10
If the height of the plant when last measured had grown back 1/10 meter, the height was last measured is expressed as [tex]\frac{3}{10}+ \frac{1}{10}= \frac{4}{10}=\frac{2}{5}[/tex]
Hence the height of the plant when it was last measured is [tex]\frac{2}{5}cm[/tex] tall

Sally and her husband, Ahmed, together earned a total of $203,300 in taxable income last year. Using the tax table, what do they owe in federal income taxes? Enter your answer rounded to the nearest dollar, such as: $42,536
Answer:
$37,141
Step-by-step explanation:
The applicable line of the tax table is ...
$28,765+24% of the amount over $168,400
If A represents the amount of taxable income, this simplifies to ...
$28,765 +0.24(A - 168,400) = $28,765 +0.24A -40416 = 0.24A -$11,651
For their income of 203,300, Sally and Ahmed owe ...
0.24×203300 -11651 = 48792 -11651 = 37141
They owe $37,141.

Answer:
X=1/174
Step-by-step explanation:
Answer:
x = -5/21
Step-by-step explanation:
The common denominator between all the terms in this equation is 30. Multiply everything by 30.
[x+1/6=3x/10] * 30
30x + 5 = 9x subtract 9x on both sides
21x+5 = 0 subtract 5 on both sides
21x = -5 divide 21 on both sides
x = -5/21
