Which points lie on the line y= -1/2x +4?
A) (-2,5) and (2,3)
B) (0,6) and (1,4)
C) (-2,5) and (4,3)
D) (-2,3) and (0,2)
Which answer choice is the equation of a line that passes through the points (1.-3) and (-1,3)? A) y = -1/3
B) -3y = x + 1
C) y = 3x
4) 3x + y = 0
Question #1
first, you need to find the slope. Use the formula: m=(y₂-y₁)/(X₂-X₁). Plug in x and y values. once you have found the slope, use point-slope form;
(y-y₁)=m(x-x₁). Again, plug in x and y values. Simplify the equation. Do that with the coordinate pairs, to see which one matches y=-1/2x+4. The answer though is A, (-2,5) and (2,3).
Question #2
Do the same thing, find the slope using the formula, and then use point-slope form. After that, find the matching equation and that's the answer. I am confused though because the right equation would be [tex]y=-3x[/tex], but that's not one of the answers.
-1/2 + 4/5v=-5/3 solve for V
Answer:
v = -35/25 or -1 11/24
Step-by-step explanation:
First, isolate the variable. We should add 1/2 on both sides of the equation to get 4/5v = -7/6. Then we divide 4/5 on both sides to get v = -35/24!

joe needs to transfer 28 quarts of oil into one gallon containers joe calculated that he needs 112 container's but he made a mistake in his calculations identify and correct his error
Answer:
The answer to your question is given below.
Step-by-step explanation:
To know the mistake that Joe made and the possible correction, we shall convert 28 quart to gallon.
This is illustrated below:
Recall:
4 quart = 1 gallon
Therefore,
28 quart = 28 quart × 1 gallon / 4 quart
28 quart = 7 gallon
Therefore, 28 quarts is equivalent to 7 gallons.
Hence, Joe made a mistake in his calculations by multiplying 28 quarts by 4 instead of dividing 28 quart by 4.

around two points: the origin and (-2,4). Sketch both points on the
graph.
Answer:
[tex]P: (-2,4)[/tex]
[tex]P' : (-4,-2)[/tex]
Step-by-step explanation:
Given
[tex]P: (-2,4)[/tex]
Required
Rotate 90 degrees counterclockwise
Show both points on graph
[tex]P: (-2,4)[/tex]
When a point is rotated counterclockwise by 90 degrees, the new point is:

Find the value of p.
Answer:
The answer is 25/13
Step-by-step explanation:
Answer:
1.923=p If you are rounding you can round to 1.9
Step-by-step explanation:
We must simply get P alone.
1400 = 2p*52*7
First we can multiply the integers
1400 = 2p*364
To get P alone we can divide by 364 on both sides
1400/364 = 2p
3.846 = 2p
Divide by 2 on both sides
3.846/2 = p
1.923 = p

what are the steps to solve m -5 - 6m 5
Answer:
m = -2
Step-by-step explanation:
m - 5 - 6m = 5
First, you need to combine like terms
-6m + m = -5m
-5m - 5 = 5
Next, add 5 to both sides of the equation
-5m - 5 = 5
+ 5 + 5
-5m = 10
Divide -5 by both sides of the equation
-5m = 10
÷-5 ÷-5
m = -2

What is the slope of a line perpendicular to the line whose equation is
2x+12y=−192. Fully reduce your answer.
The slope of a line would be -6 which is perpendicular to the line whose equation is 2x+12y=−192.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
We have to determine the slope of a line perpendicular to the line whose equation 2x + 12y = −192.
First, we have to find the slope of the given line
The equation of the line which is given as
2x + 12y = −192
12y = −192 - 2x
Divided by 12 both sides of the above equation to get the slope-intercept form
y = - (1/6)x - 16
Here the slope of the line (m) = -1/6
So the slope of the line perpendicular to the line will be: 1/m = 1/(-1/6) = - 6.

6. Mr. Phuong stayed in a hotel room for 2
nights that cost $210. The hotel room tax
rate in the city is 12%. What is the total cost
for the hotel room? (Example 2)
Answer:
The total cost of the hotel room is $235.20
Step-by-step explanation:
Here, we want to find the total cost of the hotel room
Total cost of hotel room = Cost of hotel room for the two nights + tax
Tax = 12%
Total cost = 210 + 12% of 210
Total cost = 210 + (12/100 * 210)
Total cost = 210 + 25.2
Total cost = $235.2

2x-9x+17=-4
I have a answer but I’m not sure if I’m correct so I just want to double check.
Answer: x = 3
Step-by-step explanation: Simplify both sides
2x - 9x + 17 = -4
2x + - 9x + 17 = -4
Combine like terms
(2x + -9x) (17) = -4
-7x + 17 = -4
Subtract 17 from both sides
-7x + 17 - 17 = -4 - 17
-7x = -21
Divide both sides by -7
-7x/-7 = -21/-7
x = 3
Answer:
x=3
Step-by-step explanation:
subtract 2x and 9x ( 2x-9x= -7x)subtract 17 and -4 ( -4 -17= -21)divide -21 and -7 ( -21 / -7= -3)x=33 Equivalent ratios for the following ratio: 3:4

Answer:
:) /
Step-by-step explanation:,,
Answer:
The answer is B:subtract 1,add x,divide by 4
The other answer is D:add x,subtract 1,divide 4
Step-by-step explanation:
when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3
the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=[tex]\frac{3}{4}[/tex]
The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=[tex]\frac{3}{4}[/tex]
With that evidence I can reasonably say that answer to the question is B,and D

Substituting it would get to [tex](-1.9)^{2}(-7) + (-7)[/tex].
First you solve the exponent which would get it to [tex](3.61)(-7) + (-7)[/tex].

A basketball team played five games. In those games, the team won by 7 points, lost by 3, won by 4, lost by 2, and won by 9. What was the mean difference in game scores over the five games?
Answer:
3
Step-by-step explanation:
7-3+4-2+9=15
15/5=3
The mean difference in the game scores over the five games is = 5
The points achieved by the various team players =
won by 7, lost by 3, won by 4,lost by 2,won by 9.To obtain the mean of the points achieved from the five
games the five scores are added together and divided by the number of games which is 5.
That is,
[tex] \frac{7 + 3 + 4 + 2 + 9}{5} [/tex]
[tex] \frac{25}{5} = 5[/tex]
Therefore the mean difference in game scores over the five games is = 5
