Solve for n.
19n+20≥1
Answers
\(19n + 20 \geqslant 1\)
\(19n + 20 - 20 \geqslant 1 - 20\)
\(19n \geqslant - 19\)
\( \frac{19n}{19} \geqslant \frac{ - 19}{19} \)
\(n = - 1\)
Answer:
\(n\geq -1\)
Step-by-step explanation:
\(19n+20\geq 1\)
\((19n+20)+(-20)\geq 1+(-20)\)
\(19n\geq -19\)
\(\frac{19n}{19} \geq \frac{-19}{19}\)
\(n\geq -1\)

How do I graph y = -1 = 2x and y = -4 + 2x?
Answers
Answer:
Slope = Rise/Run
To graph, you first need the y-intercept.
In y = -1 + 2x, the y-intercept is -1. Start in -1 and then go two units up, and 1 unit to the right which will represent the slops, 2.
In y = -4 + 2x, the y-intercept is -4, so you'll start at -4, then go 2 u its up, and 1 to the right which will represent the slope, 2.
To find y-intercept:
y = mx + b | main things: m = slope b = y-intercept

how does factoring relate to determining whether expressions are equivalent?
Answers
Answer:
Two expressions are equivalent if they can be simplified to the same third expression or if one of the expressions can be written like the other. In addition, you can also determine if two expressions are equivalent when values are substituted in for the variable and both arrive at the same answer.
two quadrilaterals that have matching angles but different side lengths.
Answers
Answer:
Step-by-step explanation:
ere are two quadrilaterals that have matching angles but different side lengths:
1.Quadrilateral ABCD:
Angle A = 90 degrees, Angle B = 60 degrees, Angle C = 120 degrees, Angle D = 90 degrees
Side AB = 5 units, Side BC = 10 units, Side CD = 5 units, Side DA = 10 units
2.Quadrilateral PQRS:
Angle P = 90 degrees, Angle Q = 60 degrees, Angle R = 120 degrees, Angle S = 90 degrees
Side PQ = 3 units, Side QR = 6 units, Side RS = 3 units, Side SP = 6 units
Both of these quadrilaterals have the same angle measures (90 degrees, 60 degrees, and 120 degrees) but different side lengths. Therefore, they are similar but not congruent.

Step-by-step explanation:
To convert this fraction to a decimal, just divide the numerator (35) by the denominator (64). So, 35 / 64 = 35 ÷ 64 = 0.546875. Approximated Values: 35 / 64 = 0.5 rounded to 1 significant figure. 35 / 64 = 0.55 rounded to 2 significant figures. 35 / 64 = 0.547 rounded to 3 significant figures.

As c increases,does the value of x increase,decrease,or stay the same for each equation? Assume c is positive.
Answers
decrease
stays same
increase
As c increases,the value of x -
1. Increase
2. decrease
3. stays same
4. increase
What is the proportionality?Proportionality indicates that two quantities or variables are related in a linear manner. If one quantity increases, so does the other and vice versa.
Now in the given question we have the following equations :
1. x-c = 0
2. cx = 1
3. cx = c
4. x/c = 1
1. x-c= 0
⇒ x = c
Hence, in this case if the value of c increases, so does the x will increase.
2. cx = 1
⇒ c= 1/x
Hence, in this case if the value of c increases, so does the x will decrease.
3. cx = c
⇒ x = 1
Hence, in this case if the value of c increases, the value of x remains the same.
4. x/c = 1
⇒ x = c
Hence, in this case if the value of c increases, so does the x will increase.
Hence, we conclude that As c increases,the value of x
1. As c increases,the value of x Increases.
2. As c increases,the value of x decreases.
3. As c increases,the value of x stays same.
4. As c increases,the value of x increases.

whats the surface area?
Answers
Answer:
1108 in²
Step-by-step explanation:
You want the total surface area of the pentagonal prism shown.
Base areaThe area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...
A = LW +1/2bh
A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches
Lateral areaThe lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.
LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches
Total areaThe total surface area of the figure is the sum of the two base areas and the lateral area:
SA = 2(114 in²) +880 in² = 1108 in²
The surface area of the composite figure is 1108 in².

$39.00 jeans
40% off
Answers
Basically to know what your final price is you need to know what percentages represent.
Since they are simply parts of a whole (because you know 100% of something is a whole) we can look them as fractions like 40/100 in this case.
Then we can multiply 39.00 by 40/100 or 0.40 in decimal form and get 15.60.
It’’s important to remember that this 15.60 is just what 40%of 39 is so we still need to subtract it from our total to get the sales price.
39-15.60=23.40
So $23.40 is the sales price

Step-by-step explanation:
Sticker price is $230
Store is having a sale, 20% off sticker price.
So first you have to do, $230 x 20% to get the price of 20%. Which is 46. Since it says off, you have to subtract. We just found out that $46 is 20%, we have to now take $46 away from the original sticker price, $230, So do
230 - 46, and you get 184. Therefore, $184 is the sticker price after the 20% sale. Now you add $184 to the price of the TV, $192. So do 192 + 184, which is 376. If you want to estimate it, it would be $400.
Answer:
around 84.4
Step-by-step explanation:
you add the original price then the store price since that's how much they marked it up and the total would be 422 then you would find 20 percent of 422.

Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.
L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)
Answers
To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).
