Step-by-step explanation:
Slope through (7, 1), (8,0)
Answer:
-1
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= (0-1)/(8-7)
= -1/1
= -1

What is the solution to the equation 5x = 40?
07
08
45
200
Answer: Should be 8 ,,,,,
Answer:
Step-by-step explanation:
well you want to isolate x so in order to undo multiplication, you divide the 5 on both side that way it cancels on the side with the x.
The answer to that is: X = 8.
40 divided by 5 = 8.
To check we can do 5 x 8 = 40.
X = 8

Calculate the slope of the line containing the points (6,-4) and (-1,-4).
Answer:
Step-by-step explanation:
(x₁ , y₁) = (6, -4) & (x₂ , y₂) =(-1 , -4)
In these two points, there is no change in y-coordinates. So, the line is parallel to x-axis.
Slope of line parallel to x-axis = 0
i want answer to this question
Answer:
a=1 D
Step-by-step explanation:
insert x=1 in the equation
Answer:
When it is divided by x-1 and it has no remainder , then it means substituting x=1 into the polynomial is zero .Because x-1 is a factor.
[tex]2 {x}^{3} - a {x}^{2} - 7x + 6 \\ x = 1 \\ 2 {(1)}^{3} - a {(1)}^{2} - 7(1) + 6 = 0 \\ 2 - a - 7 + 6 = 0 \\ 1 - a = 0 \\ a = 1[/tex]

m - 4 = 2m
Check your solution if possible
Answer:
m - 4m = 2m
-4 = 2m -m
- 2 = m
Answer:
m = -4
Step-by-step explanation:
Add 4 to both sides of the equation
Simplify
Add the numbers
= 2 + 4
Subtract 2 from both sides of the equation
=2+4
−2=2+4−2
Simplify
Divide both sides of the equation by the same term

Find the lengths of LM⎯⎯⎯⎯⎯⎯ and PQ⎯⎯⎯⎯⎯ and determine whether they are congruent.
Hint: Congruent line segments have the same length.
Answer:
The fourth option is the answer.
Step-by-step explanation:
Use distance formula
[tex] {x}^{2} + {y}^{2} = {d}^{2} [/tex]
where x is the distance between the two endpoints of the congruent line segment and y is the distance between the congruent line segment.
[tex] {3}^{2} + {6}^{2} = 45[/tex]
Set 45 equal to d^2.
[tex]45 = {d}^{2} [/tex]
[tex] \sqrt{45} = d[/tex]
[tex]3 \sqrt{5} = d[/tex]
L and M have the same distance between points as well. so they are congruent.
Mary, Peter, and Lucy were picking chestnuts. Mary picked twice as much chestnuts than Peter. Lucy picked 2 kg more than Peter. Together the three of them picked 26 kg of chestnuts. How many kilograms did each of them pick?
Answer:
Peter = 6 kg
Mary = 12 kg
Lucy = 8 kg
Step-by-step explanation:
let us take number of kg's peter took as x
then lets form an expression to find x
let us take mary's chestnuts as = 2x (twice as much as peter)
let us take Lucy's chestnuts as = 2 + x (picked 2 kg more than peter)
so
x + 2x + 2+ x = 26
4x + 2 = 26
4x = 26 - 2
4x = 24
x = 24/4
x = 6
now let us see how much each of them picked while replacing 6 by x
Peter = x
= 6 kg
Mary = 2x
= 2(6)
= 12 kg
Lucy = 2+x
= 2 + 6
= 8 kg
now let us cross check to see the answer
6 + 12 + 8
18 + 8
= 26

Write the slope-intercept form of the equation of the
line through the given point with the given slope.
10. through: (5, -3), slope -4/5.
Answer:
y = -4/5x + 1Step-by-step explanation:
The slope-intercept form:
y = mx + b, where m- slope, b- y-interceptUse point (5, -3) and m = -4/5:
-3 = -4/5*5 + b-3 = -4 + bb = -3 + 4b = 1The line is:
y = -4/5x + 1Answer:
b = 1
Step-by-step explanation:
We know that
y = mx + b
-3 = -4/5 × 5 + b
-3 = -20/5 + b
-3 = -4 + b
-3 + 4 = b
1 = b
Hi how can I graph this if it dosn't have a slope?
1. y = (2/3)x - 1
y = -x + 4
System of Linear Equations entered :
[1] y - 2x/3 = -1
[2] y + x = 4
// To remove fractions, multiply equations by their respective LCD
Multiply equation [1] by 3
// Equations now take the shape:
[1] 3y - 2x = -3
[2] y + x = 4
Graphic Representation of the Equations :
-2x + 3y = -3 x + y = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + 4
// Plug this in for variable x in equation [1]
[1] 3y - 2•(-y +4) = -3
[1] 5y = 5
// Solve equation [1] for the variable y
[1] 5y = 5
[1] y = 1
// By now we know this much :
y = 1
x = -y+4
// Use the y value to solve for x
x = -(1)+4 = 3

What is the area of this figure?
Answer:
I love these kind of problems (yes I'm kidding,... lol) your answer is below,...
Step-by-step explanation:
To find the area of the whole shape lets view it as three seprate rectangles,... then we will find the area of the three seperate shapes and add the areas together,... (english scholler voice): "Quite simple really"
For "simplicitys sake" lets view the shape as a house blueprint, no house I would want to live in, but a house non-the-less,... you have the main part of the house (the largest rectangle, the 13yd x 24yd one) the hallway in the middle (the 14yd x 6yd rectangle) and finally the really ridiculous sized I-du-know,... kitchen (the 5yd x 17yd one) Sooo,... lets go,...!
First of all if you didn't follow how I got the three rectangles then it's "quite simple really!" all I did is: take the oppposite side of the very far left side (the one that says 24yd) where is says 7yd and 11yd and because we know that the 7yd + 11yd + the-part-that-we-don't-know-how-long-is, is all = to 24yd then we know that the part that is not labled (the "doorway" from the main part of the house to the hallway) has to be 6yd because 7yd + 11yd + 6yd = 24yd,... AND know we know that that side of the "hallway" is 6yd, so the "hallway" is 6yd x 14yd,... So,...
13yd x 24yd = YES!... 312yd
14yd x 6yd = RIGHT again!... 84yd
5yd x 17yd = YOU are SO LIT,... yes it's 85yd
Alright so we have 312yd and 84yd and 85yd,... all we have to do is add 'em all up and you will have the area of your houseprint,... You got it!
312yd + 84yd + 85yd = (drum roll please,...) 481yd,...
The area of you shape is 481yd,...
So glad to have worked with ye and me thinks that that hopefully helped,...
CHOW,...!
