Answer:
Not entirely sure about what the question is asking, but explanation of what I think it is asking.
Step-by-step explanation:
There are three basic rules of addition.
Positive + Positive = Positive Ex: 1+1=2
Negative + Negative = Negative Ex: -2+-2=-4
Negative + Positive = Positive or Negative depending on the value.
Ex= 1+(-2)=(-1)
Ex=2+(-1)=1
So subtraction problems can be turned into addition problems.
For example:
4-2 is the same as 4+(-2).
Or -5-7 is the same as -5+(-7).
Hope this makes sense.

9. Find the point of intersection of the lines: y = 4x + 1 and y = - 2x + 4 A. (2,9) B.(1/2,3) C. (1,2) D. (1/4,2)
Step-by-step explanation:
y = 4x + 1 and y = -2x + 4
4x + 1 = -2x + 4, 6x = 3, x = 0.5
When x = 0.5, y = 4(0.5) + 1 = 3.
The point of intersection is (0.5, 3). (B)
Step-by-step explanation:
y = 4x + 1
A.(2,9)
y = 4(2) + 1 = 9
y = 9.
y = 4x + 1
9 = 4x + 1
9 - 1 = 4x
8 = 4x => x = 8÷4 = 2
x = 2.
y = -2x + 4.
A.(2,9)
y = -2(2) + 4 = 0
y = 0.
y = - 2x + 4
0 = -2x + 4
0 - 4 = 2x
0 = 2x => x = 0 ÷ 2 = 0
x = 0.
y = 4x + 1
B.(1/2, 3)
y = 4(1/2) + 1
y = 4 ÷ 2 + 1 = 3
y = 3.
y = 4x + 1
3 = 4x + 1
3 - 1 = 4x
2 = 4x => x = 2 ÷ 4 = 1/2
x = 1/2.
y = - 2x + 4
B.(1/2, 3)
3 = - 2x + 4
3 - 4 = - 2x
- 1 = - 2x => x = 1/2
x = 1/2.
y = - 2x + 4
y = - 2(1/2) + 4
y = -2(0.5)+ 4
y = -1 + 4 = 3
y = 4x + 1
C.(1,2)
y = 4(1) + 1 = 5
y = 5.
y = 4x + 1
5 = 4x + 1
5 - 1 = 4x
4 = 4x => x = 4÷4 =1
x = 1.
y = -2x + 4
C.(1, 2)
y = - 2(1) + 4
y = - 2 + 4 = 2
y = 2.
2 = -2x + 4
2 - 4 = - 2x
- 2 = - 2x => x = 2÷2 = 1
x = 1.
y = 4x + 1
D.(1/4, 2)
y = 4(1/4) + 1
y = 4(0.25) + 1
y = 1 + 1 = 2
y = 2.
y = 4x + 1
2 = 4x + 1
2 - 1 = 4x
1 = 4x => x = 1/4
Point A is the point of intersection of the lines.

Need answer asappp!!!
Which point is located at (4, 1)?
A
B
C
D
Answer:
A is located at (4,1)
Step-by-step explanation:
The first number will always be on the x-axis and the second will always be on the y-axis. For example: (x,y) so A is (4,1) , B is (-4,1), C is (1,4) and D is (-1,4).
Hope this helps! ;)
Final Answer: Point A
Steps/Reasons/Explanation:
Question: Which point is located at [tex](4, 1)[/tex]?
The x-axis would be 4 and the y-axis would be 1. The x-axis is horizontal and the y-axis is vertical.
For the x-axis, it tells you the markings of the numbers, so moving to the right would be positive and left would be negative.
For [tex](4, 1)[/tex] we would go four to the right and one up. Point A is located there.

Solve the equation
56 ÷ (-8)= ?
Answer:
-7
Step-by-step explanation:
Because for dividing one positive and one negative number, the rule is that the answer is going to be negative. So, what you can do is just do 56÷8 which equals 7 then add the negative sign to make it -7.
Tara has ridden her bike .5 miles and
rides 10 miles per hour. Felipe has
ridden his bike .25 miles and rides 15
miles per hour. For what number of
hours will-Tara have ridden less miles
than Felipe?
Answer:
0.5 hours
Step-by-step explanation:
Given that Tara has covered 0.50 miles and rides with a speed of 10 miles/hour. Felipe has covered bike 0.25 miles and rides with a speed of 15 miles/hour.
Tara has covered more distance while the speed of Felipe is more than the speed of Tara.
Assuming that in time t hour, Felipe reaches Tara, then Tara left behind as Felipe has faster speed.
So, after t hour, Felipe will be ahead of Tara and Tara will cover lesser miles than Felipe .
As distance = speed x time, so
So, the distance covered by Tara in [tex]t[/tex] hour = 10t miles and she already has covered 0.5 miles, so total distance covered by Tara [tex]= 0.5+10t[/tex] miles.
Similarly, the distance covered by Felipe in [tex]t[/tex] hour = 15t miles and he already has covered 0.25 miles, so the total distance covered by Tara [tex]= 0.25+15t[/tex] miles.
Therefore, at the time then Felipe reached Tara, both have covered the same distance, i.e
[tex]0.25+15t=0.5+10t \\\\\Rightarrow 15t-10t=0.5-0.25 \\\\\Rightarrow 5t=0.25 \\\\[/tex]
[tex]\Rightarrow t= 0.25/5=0.5[/tex] hour
Hence, after 0.5 hours Tara will cover lesser miles than Felipe .
Answer:
0.5 hours

Mariana is choosing a beverage to drink. She wants a beverage with no more than 3 grams of sugar per ounce. Which beverages meet Mariana's requirements?
Answer:
Step-by-step explanation:
The main beverage that would easily meet Mariana's requirements would be water as it contains no sugar. Other than these two flavored options that she can choose from would be to make home-made Ice-tea or lemonade. Therefore, she can choose the amount of sugar to add without going over her own requirements, but still having a delicious beverage to drink.

Use the elimination Method to solve the system of equations. Choose the correct ordered pair.
6x + 4y = 32
-6x+4y = 8
A: 4,2
B: 1,5
C: 0,8
D: 2,5
Answer:
D, 2; 5
Step-by-step explanation:
Sum the equations vertically to eliminate at least one variable.
You will obtain 8y = 40.
Divide both sides by 8. You will get y = 5.
Now we know the value or y. Substitute this value into the second equation (-6x+4y = 8). You will get -6x+(4×5) = 8. Multiply 4 and 5: -6x+20 = 8.
Solve for x by moving 20 to the other side and switching sign: -6x = 8-20.
So: -6x = -12 and therefore x = 2.
So now we know the value of x and y.
(x; y) = (2; 5)
Find two numbers that Multiply to -40 and add to 6
What is the volume of this figure?
Answer:
The total volume of this 3D Figure is 944.
Step-by-step explanation:
The volume of:
1. The above figure is 400.
2. The bottom figure is 544.
3. Add the total volume of those 2 figures (400+544).
4. You have found the final answer!
Brainliest? Thanks!Answer:
So the first part of this shape is 400 ft and the secound part of this shape is 544 ft. Hence, since want the whole shape volume your answer would be and always will be 944 ft.
Step-by-step explanation:
since i'm pretty good at math I well tell you how I got this answer in this qustion I seen that this figure is 3-dimensional meaning that we have height,length, and width ( there is two more and were not going to talk about it ) prove we got to time not 2 but 3 times and since this figure has 2 part we would need to brake it into and mutlply both parts (sepertly) to get the answer right so for the first part (or what on the top).
1st part
since the height is 5 ft. that is the first part of our equation,I see that the width must be 10 ft., which well be the second part of our equation, and i see the length is 8 ft so our equation is , 8x10x5 witch mean the first part of the figure is 400 ft
2nd part
since the height is 4 ft. this mean we have the first part of our equation,the width is 8 ft so that the second part of our equation,and I see the length is 17 ft., means this equation is 4x8x17 so this part of the figure is 544 ft.
The whole figure
So with are info from the first and second part of our equation we can now add both parts of the figures means if we add both of them the answer would be 944 ft.
if you don't other stand here a tip:In geometry, a three-dimensional shape can be defined as a solid figure or an object or shape that has three dimensions – length, width and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth.

y=-4/5x+26/5
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=2-(-2)/4-9
m=4/-5
m=-4/5
y-y=m(x-x¹)
y-2=-4/5(x-4)
y-2=-4/5x+16/5
+2 +2
y=-4/5x+26/5

Graph the inverse of each function
Please show work will give brainillest
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The graph of the inverse of a function is its reflection in the line y=x. In the attached, that line is shown as a dashed yellow line. The inverse function is shown as a blue line.
__
One way to plot the inverse function of a line is to swap the x- and y-coordinates of the line's intercepts.
In A, the x-intercept is about 10, and the y-intercept is about -4. For the inverse function, the y-intercept will be 10 and the x-intercept will be -4.
In B, the x- and y-intercepts of the function are -6 and 6, respectively. For the inverse function, they will be 6 and -6, respectively.
Answer:
In A, the x-intercept is about 10, and the y-intercept is about -4. For the inverse function, the y-intercept will be 10 and the x-intercept will be -4.
In B, the x- and y-intercepts of the function are -6 and 6, respectively. For the inverse function, they will be 6 and -6, respectively.
