which graph best describes the slope of the line in the graph? a) positive b) negative c) zero d) undefined
pleassseeeee
Ok, so you didn't put any picture to go along with the question but hey, thats ok because I can still help you.
In order for a graph to be positive, it has to be leaning to the right.
In order for a graph to be negative, it has to be leaning to the left.
In order for a graph to be zero, it has to be horizontal.
In order for a graph to be undefined, it has to be completely vertical.
You can look at the picture below if you still need help.
P.S. The picture with the yellow lines is the ones that are zero and undefined. The yellow line on the left is undefined, the yellow line on the right is zero.

Step-by-step explanation:
Sheldon's brother shoveled 2/3 of the driveway
Remaining portion = 1 - ⅔
= (3-2)/3
= 1/3
Sheldon shoveled 3/4 of what was left= ¾ × ⅓
= ¼
Sheldon shoveled ¼ or 0.25 of the driveway
Ahmed shoveled ⁴/5 of half of the driveway = 4/5 × ½
= 2/5
Ahmed shoveled 2/5 or 0.4 of the driveway
0.4 > 0.25
therefore, Ahmed will have the larger area to shovel
Answer:
Ahmed shoveled more
Step-by-step explanation:
you need to do 3/4 - 2/3 which is 1/12 so the you do 1/12 x 3/4 = 3/48
compare with 4/15 and 4/15 is higher so that what you got wrong

whats the measure of angle 1
Answer:
1 = 70
Step-by-step explanation:
The triangle is an isosceles.
Subtract the angle 40 from 180 (all angles in a triangle add up to 180
The bottom two angles are the same, so dividing the number given by 180 - 40 by 2
180 - 40 = 140
140 / 2 = 70

The remainder when the polynomial is divided by x + 1 is 2
Given the function P(x)=3x^4 −2x^3 +2x^2 −1, to get the rmainder if the polynomial is divided by x + 1, we will substitute x = - 1 into the function to have:
P(-1) = 3(-1)^4 −2(-1)^3 +2(-1)^2 −1
P(-1) = 3(1) - 2 + 2(1) - 1
P(-1) = 1 + 1
P(-1) = 2
Hence the remainder when the polynomial is divided by x + 1 is 2

Solve the following for :
60/3=x/4
Answer:
80
Step-by-step explanation:
60/3 becomes 20 and then it says equal to 1/4 x because x divided by 4 so we multiply by 4 to get 80
Solve.
x−8.2=−9.09
What is the solution to the equation?
Enter your answer in the box.
x =
[tex]x-8.2=-9.09\\\\\implies x = -9.09 +8.2 =-0.89[/tex]
x = -0.89
Step-by-step explanation:
when subtracting a positive number to a negative it will always be negative or atleast 0. It is like a number line, when subtracting on a number line, you always go left, which is also why its negative.
How I solved it: (just another way to solve this)
9.10-8.20=0.89
since the 9.10 was actually a negative(-9.10), it would make 0.89 negative, making it -0.89.
What is the graph for y = { x + 1?

a)
b)
c)
d)
Enter
Answer:
The graph for y = (1/2)x + 1 is C.
Step-by-step explanation:
y = (1/2)x + 1
This line has a slope of 1/2. That is a positive line, so option A is incorrect. It also has a y-intercept of 1. The value of y when x is zero is 1. There are two graphs in which the line intersects (0,1): A and C. But A has already been rejected, so it must by Graph C:
Double check this to see if the slope is 1/2. Does y increase by 1/2 for every step of 1 on x? Graph C:
x y
-2 0
-1 1/2
0 1
+1 1 1/2
+2 2
Yes: Y increases by (1/2) for every x increase of 1.
The graph for y = (1/2)x + 1 is C.
HELP WITH THESE 3 QUESTIONS (BRIANLIEST AND 50 POINTS) hint: question 1 is answered (NO LINKS)
Amos scored 100 points while playing 3 rounds of a game.
Round 1 : 30 points
Round 2 : 25 points
Round 3 : ?
How many points did he score in round 3?
Complete the steps to solve the problem
1. What do you need to solve for in this problem? Choose a variable to represent this unknown value. answer: Round 3 = x
x + 30 + 25 = 100
2. Using the variable you chose, write an equation to represent this situation. (Hint: You may want to put the number of points in each round on one side and the total number of points on the other.
3. Solve this equation to find how many points Amos scored in round 3. Show your work.
Answer:
45 points in round 3
Step-by-step explanation:
x + 30 + 25 = 100
combine like terms
30+25 = 55
x + 55 = 100
- 55 - 55
--------------------
x = 45
therefore, Amos scored 45 points in round 3
hope this helps! :D
have a MIRACULOUS day, and brainliest is immensely appreciated!! <3
Answer:
x = 45 points
Round 3 : 45 points
Step-by-step explanation:
Starting Information:
100 points = 3 rounds
Round 1 : 30 points
Round 2 : 25 points
Round 3 : x
Subtraction:
To find x we need to subtract 30 and 25 from 100
100 - 25 - 30 = x points
Combine -30 and -25 into -55
100 - 55 = x
100 - 55 = 45
In round 3 he scored 45 points
Addition:
To find x we need to add 30 + 25 + x and get a sum of 100
25 + 30 + x = 100
Combine 25 and 30
55 + x = 100
Subtract 55 from each side
x = 45
Here are the 2 expressions I used:
25 + 30 + x = 100
100 - 25 - 30 = x

My work is not number assigned but hopefully you can understand it :)

how to turn x+7y=20 into y=mx+b
Answer:
y = -1/7x +20/7
Step-by-step explanation:
Solve for y.
7y = -x +20 . . . . . subtract x from both sides to get the y-term by itself
y = -1/7x +20/7 . . . . divide both sides by the coefficient of x
In this form, you can see ...
m = -1/7b = 20/7 = 2 6/7Answer:
y=-1/7x+20/7
Step-by-step explanation:
So they are asking us to put x+7y=20 into slop-intercept form (y=mx+b).
They're pretty much just asking us to solve for y.
x+7y=20
7x=20-x (Subtract x from both sides)
y=20-x/7 (Divide 7 on both sides to isolate y)
y=20/7-1/7x
y=-1/7x+20/7
So..
m=-1/7
b=20/7
Hope this helps :)

what is y-2=4(x+1) in slope intercept form
Answer: y=4x+3
Step-by-step explanation: First, lets clean this expression up.
y - 2 = 4(x+1)
Multiply 4 times x and 4 x 1.
y-2=4x+1
add 2 to both sides.
Finally, you get y=4x+3.
Remember that 4 is your m (slope), and b (y-intercept). If you were graph this, it would increase to the right. You graph your intercept 3 on the positive y-axis at (0,3) and since your slope is 4x, you go 4 units up and 1 unit to the right and from there, you get the graph of the given equation.
Hope this explanation helps.

Estimate a 15% tip on a dinner bill of $32.43 by first rounding the bill amount to the nearest ten dollars.
Answer:
Estimate Tip = $4.50
Step-by-step explanation:
The bill to the nearest $10 is $30.00 : ( $ 30 ($32.43) $40, it is nearer to $30
Estimate Tip = Bill rounded to the nearest $10 × Tip %
Estimate Tip = $30 × 15%
Estimate Tip = $30 × .15 (15% change to a decimal is .15)
Estimate Tip = $4.50

Last year, Kristen read a total of 30 fiction and non-fiction books. The number of non-fiction books was 5 less than 4 times the number of fiction books.
What is the total number of FICTION books that Kristen read last year?
A. 5
B. 7
C. 23
D. 25
Answer:
7 fiction and 23 non- fiction
Step-by-step explanation:
The number of non-fiction read was 5 less than 4 times the number of fiction books.
Assume fiction books are x.
An equation representing this would be:
x + (4x - 5) = 30
5x - 5 = 30
5x = 30 + 5
x = 35 / 5
x = 7 fiction books
Non-fiction books:
= 4x - 5
= 4 * 7 - 5
= 23 non - fiction books
