Answer:
slope = - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x + y = - 7 ( subtract x from both sides )
y = - x - 7 ← in slope- intercept form
with slope m = - 1
Parallel lines have equal slopes
then the slope of a line parallel to it is - 1
Craig bought 8 folders and notebooks for school folders costs 50 cents and notebooks costs a $50 Craig spent a total of $6 how many folders and how many notebooks did he
buy
The number of folders and notebooks in the equation is given by 3 and 5 respectively.
How to find number of folders and notebooks?let
x = number of foldersy = number of notebooksThe equation:
x + y = 8
0.50x + 1.0y = 6
From (1)
x = 8 - y
Substitute x = 8 - y into (2)
0.50(8 - y) + 1.0y = 6
4 - 0.50y + 1.0y = 6
4 + 0.40y = 6
4 - 6 = -0.40y
-2 = - 0.40y
y = -2 / 0.40
y = 5
Recall
x + y = 8
x + 5 = 8
x = 8 - 5
x = 3

Answer:
x = -3, 0, or 7
Step-by-step explanation:
After removing common factors, the remaining quadratic can be factored by comparison to the factored form of a quadratic.
__
Step 1Write the equation in standard form.
4x³ -16x² -84x = 0
Step 2Factor out the common factor from all terms.
= 4x(x² -4x -21) = 0
Step 3Compare to the factored form of a quadratic:
(x +a)(x +b) = x² +(a+b)x +ab
This tells you the constants 'a' and 'b' in the factors can be found by considering ...
(a+b) = -4 . . . . the coefficient of the x term of the quadratic
ab = -21 . . . . . the constant term of the quadratic
It is often helpful to list factor pairs of the constant:
-21 = (-21)(1) = (-7)(3) . . . . integer pairs that have a negative sum
The sums of these pairs are -20 and -4. We are interested in the latter. We can choose ...
a = -7, b = 3
Step 4Put it all together.
4x³ -16x² -84 = (4x)(x -7)(x +3) = 0 . . . . . factored form of the equation
Step 5Apply the zero product rule. This rule tells you the product of factors will be zero when one or more of the factors is zero:
4x = 0 ⇒ x = 0
x -7 = 0 ⇒ x = 7
x +3 = 0 ⇒ x = -3
Solutions to the equation are x ∈ {-3, 0, 7}.
_____
Additional comment
What we did in Step 3 is sometimes referred to as the X-method of factoring a quadratic. The constant (ab product) is put at the top of the X, and the sum (a+b) is put at the bottom. The sides of the X are filled in with values that match the product and sum: -7 and 3. The method is modified slightly if the coefficient of x² is not 1.

which is greater, 2,670 meters or 2 kilometers? explain.
Answer: 2,670 meters
Step-by-step explanation:
2 kilometers = 2000 meters
2,670 > 2000
The greater value between 2,670 meters or 2 kilometers is 2,670 meters.
What is unit conversion?
It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
We are given that;
Two measurements 2,670 meters or 2 kilometers
Now,
To compare 2,670 meters and 2 kilometers, we need to convert them to the same unit of measurement.
There are 1,000 meters in a kilometer. So 2 kilometers is equal to:
2 km * 1,000 m/km = 2,000 meters
Now we can compare 2,670 meters and 2,000 meters. We can see that 2,670 meters is greater than 2,000 meters, because 2,670 is a larger number than 2,000.
Therefore, by conversion the answer will be 2,670 meters is greater than 2 kilometers.

Which line plot displays a data set with an outlier?
Answer: See attached, the top right
Step-by-step explanation:
What is an outlier? An outlier, in a data set, is a data value that is outside the overall pattern of distribution.
This means the answer to your question is the top right because the data value of 13 is outside the overall pattern, hence an outlier.
Answer:
The 2nd one on the top
Step-by-step explanation:
It's that one because it goes from 8 to 13 and that's a big jump causing it to be the outlier.

lemonade. On Tuesday, he sold 14 more cups than he sold on Monday.
Choose the expression below that shows how many cups of lemonade
Jacob sold on Tuesday.
a) 14 - x
b) x + 14
c)X - 14
d) x2 + 14
What expression would I use
Answer:
b) x + 14
Step-by-step explanation:
If I sold 14 more cups that what I sold Monday, then my answer should be (what I sold Monday) + (14).
Its like saying suppose I drank x gallons of water today. And next day, I drank 14 more gallons than yesterday. That means, I drank the initial amount of gallons (x) & 14 more gallons today (x+14)

Step-by-step explanation:
Penelope has a bag that contains orange chews, apple chews, and lime chews. She performs an experiment. Penelope randomly removes a chew from the bag, records the result, and returns the chew to the bag. Penelope performs the experiment 33 times. The results are shown below:
A orange chew was selected 13 times.
A apple chew was selected 9 times.
A lime chew was selected 11 times.
Based on these results, express the probability that the next chew Penelope removes from the bag will be apple or lime as a percent to the nearest whole number.
The probability that the next chew Penelope removes from the bag will be apple or lime as a percent is 60.6%.
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.
Here, Number of apple and lime is 9 + 11 =20
Total bag contains = 13 + 9 + 11 = 33
Probability = Number of apple or line / Total
= 20 / 33
= 60.6 %
Thus, The probability that the next chew Penelope removes from the bag will be apple or lime as a percent is 60.6%.

Answer:
C
Step-by-step explanation:
In the unit circle
cos x corresponds with x
sin x corresponds with y.
Here, they are both negative so the angles lies in the third quadrant because both x and y is negative in the third quadrant
Step-by-step explanation:
the other answer we is correct.
here a few words about why :
the quadrants in a circle start in the right top corner. so, right top is number I.
left top is number II.
left bottom is number III.
right bottom is number IV.
simply because this goes with the growing angle. the angle starts at 0° at the right center. and then it grows counterclockwise and goes all around the circle until reaching 360° being equal to 0° again.
