False, the slope should be 2x not 2y.y'all i need help immediately
Answer:
Option B
Step-by-step explanation:
Don't trust answers teachers don't bother to spell correctly. Plus, finding the 100th term is very easy.
However, the explicit formula will take a long time to use, because it's explicit.
Option C is just wrong. You're supposed to multiply in the recursive formula.
Option D might be correct, but never trust those answers. Teachers do that to trip you up

If the value of x is -4, which inequality is true?
Sue walked 3.38 miles. Alex walked five times as many miles as Sue. Dan walked 4.68 miles more than Alex. How far did Dan walk
Answer:
21.58 miles
Step-by-step explanation:
First let's find how many miles Alex walked.
It said "Alex walked five times as many miles as Sue" so lets multiply 3.38 with 5: 3.38 x 5 = 16.9
So, Alex walked 16.9 miles. Now we can find Dan's.
It said "Dan walked 4.68 miles more than Alex" so lets add 4.68 to 16.9: 16.9 + 4.68 = 21.58
So Dan walked 21.58 miles

Please simplify: 5x + 2 (x - 3) = -2 (x - 1)
Answer:
x= 8/9
Step-by-step explanation:
Open everything up to get 5x+2x-6=-2x+2. Move numbers with an x to the left side and without to the right to have 5x+2x+2x=2+6. Simplify to have 9x=8. Divide by 9 which leaves you with x= 8/9

Bamboo grows at a rate of 3 inches every month. Gina planted Bamboo when it was initially only 11 inches. -Create an explicit formula for this situation. -How tall will the plant be after 6 months?
I’ll give brainliest if you are correct.
Please answerrrrr
Answer:
Step-by-step explanation:
initial growth = 11
growth in 6 months= 3*6= 18
Final growth = 29 inches (11+18)
Triangle XYZ is reflected across the x-axis, and X = (–11, 8). What are the coordinates of X’ ?
Here are your choices:
A) (11,–8)
A) (–8, 11)
A) (11, 8)
A) (–11, –8)
I hope this question isn't confusing you guys∪ω∪
9514 1404 393
Answer:
(-11, -8)
Step-by-step explanation:
Reflection across the x-axis changes the sign of the y-coordinate.
For X(-11, 8), the reflected point is X'(-11, -8). (matches the last choice)

The sides of an equilateral triangle are reduced by 12 units, 13 units and 14 units respectively and a right-angle triangle is formed. Find the length of each side of the equilateral triangle?
Answer:
the length of each side of the equilateral triangle = 17
Step-by-step explanation:
suppose the side length of equilateral triangle = x
The 3 side of right triangle formed (by side length): x-12 , x-13, x-14
(x-13)² + (x-14)² = (x-12)² .... Pythagorean theorem
x² -26x + 169 + x² -28x + 196 = x² -24x + 144
x² - 30x +221 = 0
(x- 17) (x - 13) = 0
x = 17 or x = 13
if x = 13 the right triangle will have a side length of 13-13=0 ... not solution
x = 17
check: 17-12=5 17-13=4 17-14=3

A lab scale weighs 3 pounds, 5 ounces. Which of the following is the scale weight in (oz)?
a. 35 oz
b. 53oz
c. 41
d. 29oz
Answer:
53 ounces
Step-by-step explanation:
We know that,
1 pound = 16 ounce
3 pounds = 48 ounces
We need to find the weight in 3 pounds, 5 ounces.
3 pounds, 5 ounces = 48 ounces+ 5 ounce
= 53 ounces
So, the scale weight is 53 ounces. Hence, the correct option is (b).

Find the slope and Y intercept from the equation 12x+3y=6
Answer:
slope = -4 y-intercept = (0, 2)
Step-by-step explanation:
12x + 3y = 6
-12x -12x
-----------------------------------------------
3y = -12x + 6
3y/3 = -12x/3 + 6/3
-----------------------------------------------
y = -4x + 2 ( this is in y = mx + b form, m representing the solpe and b representing the y-intercept)
This being said, the slope = -4 and the y-intercept = (0, 2).
When a numerator equals zero, a ratio is what?
Answer:
A numerator is allowed to take on the value of zero in a fraction. Any legal fraction (denominator not equal to zero) with a numerator equal to zero has an overall value of zero. all have a fraction value of zero because the numerators are equal to zero.

Step-by-step explanation:
An on-demand printing company has monthly overhead costs of $1,900 in rent, $450 in electricity, $80 for phone service, and $230 for advertising and marketing. The printing cost is $40 per thousand pages for paper and ink. The average cost for printing x thousand pages can be represented by the function C(x)= 2660+40x/x
For a given month, if the printing company could print unlimited number of pages, what value would the average cost per thousand pages approach? What does this mean in the context of the problem?
Answer:
$40
It means that when an infinite number of pages are printed in a month then the fixed cost will be negligible.
Step-by-step explanation:
Given that:
Monthly overhead costs in rent = $1900
Costs in electricity = $450
Costs for phone service = $80
Costs for advertising and marketing = $230
Printing cost per thousand pages = $40
If number of pages printed are [tex]x[/tex] thousand then cost of printing for [tex]x[/tex] thousand pages = $40[tex]x[/tex]
Average cost to print [tex]x[/tex] thousand pages can be given as:
(Total fixed cost + Total cost of printing [tex]x[/tex] thousand pages) divided by [tex]x[/tex]
[tex]\dfrac{2660+40x}{x}[/tex]
Now, it is given that an infinite number of pages are printed in a month, and we have to find the value that average cost would approach to.
[tex]\lim_{x \to \infty} (\dfrac{2660+40x}{x})[/tex]
Let us solve the above limits.
[tex]\Rightarrow \lim_{x \to \infty} (\dfrac{2660}x+\dfrac{40x}{x})\\\Rightarrow \lim_{x \to \infty} (\dfrac{2660}x)+40\\\Rightarrow 40+\lim_{x \to \infty} (\dfrac{2660}x)[/tex]
When
[tex]x\rightarrow \infty\Rightarrow \frac{2660}{x} \rightarrow 0[/tex]
Putting the value in the limits, we get:
Average cost per thousand pages month would approach to [tex]\rightarrow \$40[/tex]
It means that when an infinite number of pages are printed in a month then the fixed cost will be negligible.

What are some of the more significant limitations of mathematical models as imitators/predictors of natural phenomena
Answer:
See explanation
Step-by-step explanation:
A mathematical model refers to a mathematical function that describes natural phenomena.
Models are used to approximate natural phenomena hence they are not really exact representations of reality. Thus mathematical models are inherently imperfect and so is our understanding of natural phenomena represented by these mathematical models.
The mathematical parameters used in models to represent real processes are uncertain since they are determined from experiment or represent more than one process.
Lastly, the initial and the boundary conditions in a model may not be explicitly established.

The average person that weighs 150 pounds has approximately 4.5 liters of blood in their body. Based on that same scale, supposedly how many liters of blood would a 250 pound person have?
Answer:
First you find how many pounds for 1 litre of blood. Trick is if you divide x by y, the answer you get will follow the unit of x. So if you divide 150 pounds by 4.5 litres, the answer will be 33.33 pounds per litre. So how many 33.33... is there in 250? Just divide 250 by 33.333 or (150/4.5), you'd get 7.5. That means for there's 7.5 parts of 33.333 pounds in 250 pounds. And if 33.333 pounds is equal to 1 litre of blood, you get 7.5 liter!

Question on the picture:)
Answer:
a. No
b. Yes
Step-by-step explanation:
a.
x - 4 = 12
x - 4 + 4 = 12 + 4
x = 16
16 ≠ 8
Therefore, the following value given for problem a is not a solution to the given equation.
b. (3 + x)/4 = 3
(3 + x)/4 * 4 = 3 * 4
3 + x = 12
3 + x - 3 = 12 - 3
x = 9
9 = 9
Therefore, the following value given for problem b is a solution to the given equation.
Find the value of the x in the equation 4(6x-9.5)=46
Answer:
3.5
Step-by-step explanation:
First you distribute. 24x-38=46.
Then add 38 to both sides
24x=84
Then divide both sides by 24
x=3.5
Answer:
x= 3.5
Step-by-step explanation:
[tex]4(6x-9.5)=46\\24x-38=46\\ +38 +38\\\\frac{24x}{24} = \frac{84}{24} \\ x=3.5[/tex]
