Answer:
Option 3
Step-by-step explanation:
First, you want at least 3 items for each guest. There are 35 guests, so the total amount of items, represented by x+y, must be >= 35*3=105
Next, you cannot spend more than $150, so the total price, represented by 1.3x+1.2y, must be <= 150

standard form (ax + by = c) to slope-intercept form (y = mx + b)
x-y= -8 (ANSWER?)
Answer:
y = x + 8
General Formulas and Concepts:
Algebra I
Equality PropertiesStep-by-step explanation:
Step 1: Define
Standard Form: x - y = -8
Step 2: Rewrite
Find slope-intercept form
Subtract x on both sides: -y = -x - 8Divide -1 on both sides: y = x + 81/8 + c = 4/5
Find what c is
c = 27/40

The length of a rectangle is eight more than twice its width. The perimeter is 96 feet. Find the dimensions of the rectangle
Answer:
The width of the rectangle is 14'8", and the length is 33'4"
Step-by-step explanation:
We're given two pieces of information:
The length is eight more than twice the width:
[tex]l = 2w + 4[/tex]
The perimeter is 96 feet:
[tex]p = 96[/tex]
We also need to apply one more piece of information that is not provided here, and that is the relationship between the perimeter of a rectangle, and it's length and width:
[tex]p = 2l + 2w[/tex]
We can solve for w by plugging the other two values into the last:
[tex]p = 2w + 2l\\96 = 2w + 2(2w + 4)\\96 = 2w + 4w + 8\\88 = 6w\\3w = 44\\w = \frac{44}{3}\\w = 14\frac{2}{3}[/tex]
Now we can find the length by plugging w into the first equation:
[tex]l = 2w + 4\\l = 2(14\frac{2}{3}) + 4\\l = 29\frac{1}{3} + 4\\l = 33\frac{1}{3}[/tex]
One third of a foot is four inches, so the width is 14'8" and the length is 33'4"
To make sure our answer is correct, we should plug those numbers back into the area equation and see if we're right:
[tex]p = 2l + 2w\\p = 2(33\frac{1}{3}) + 2(14\frac{2}{3})\\p = 66\frac{2}{3} + 29\frac{1}{3}\\p = 96[/tex]
So we know our answer's correct
25 x 130 is the same as
Answer:
ANY OF THESE
Step-by-step explanation:
1 x 3250 = 3250
2 x 1625 = 3250
5 x 650 = 3250
10 x 325 = 3250
13 x 250 = 3250
25 x 130 = 3250
26 x 125 = 3250
50 x 65 = 3250
65 x 50 = 3250
125 x 26 = 3250
130 x 25 = 3250
250 x 13 = 3250
325 x 10 = 3250
650 x 5 = 3250
1625 x 2 = 3250
3250 x 1 = 3250
The multiplication exercise involving 25 x 130 is the same as; 3250.
According to the question;
we are required to determine an equivalent of 25 x 130.By step by step evaluation,
25 × 130 = 25 (100 + 30)= 2500 + 750= 3,250Upon multiplication of 25 by 130; the result yields 3250.
Consequently, we can say 25 x 130 is the same as; 3250

parabola with focus (2, 1) and directrix x=-8
Consider we need to find the equation of the parabola.
Given:
Parabola with focus (2, 1) and directrix x=-8.
To find:
The equation of the parabola.
Solution:
We have directrix x=-8. so, it is a horizontal parabola.
The equation of a horizontal parabola is
[tex](y-k)^2=4p(x-h)[/tex] ...(i)
where, (h,k) is center, (h+p,k) is focus and x=h-p is directrix.
On comparing focus, we get
[tex](h+p,k)=(2,1)[/tex]
[tex]h+p=2[/tex] ...(ii)
[tex]k=1[/tex]
On comparing directrix, we get
[tex]h-p=-8[/tex] ...(iii)
Adding (ii) and (iii), we get
[tex]2h=2+(-8)[/tex]
[tex]2h=-6[/tex]
Divide both sides by 2.
[tex]h=-3[/tex]
Putting h=-3 in (ii), we get
[tex]-3+p=2[/tex]
[tex]p=2+3[/tex]
[tex]p=5[/tex]
Putting h=-3, k=1 and p=5 in (i), we get
[tex](y-1)^2=4(5)(x-(-3))[/tex]
[tex](y-1)^2=20(x+3)[/tex]
Therefore, the equation of the parabola is [tex](y-1)^2=20(x+3)[/tex].
Sasha is in Chicago, where a thermometer outside reads –7 °F. Anna is in New York, where a thermometer outside reads –4 °F. Which temperature is coldest and why?
Answer:
-7 is colder, so Sasha has the coldest temperature.
Step-by-step explanation:
Simple as it is, -7 is 7 degrees below 0 which means its far more negative than -4. On a number line -7 would be the farthest dot from 0 on the left which you'd want to choose.

An electric clock takes 8 seconds to sound 3 times at 3:00. How long would it take to sound 6 times at 6:00?
Answer:
16 seconds
Step-by-step explanation:
You basically have to do all numbers times 2
The required time the electric clock would take to sound 6 times is 16 seconds at 6:00.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
It takes 8 seconds for an electric clock to sound 3 times, so it takes,
= 8 / 3 = 2.67 seconds to sound once.
Therefore, the time it would take
= 2.67 × 6
= 16 seconds
Thus, the required time the electric clock would take to sound 6 times is 16 seconds at 6:00.

The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 185 grams of a radioactive isotope, how much will be left after 6 half-lives?
Use the calculator provided and round your answer to the nearest gram.
Answer:
Approximately 3 grams left.
Step-by-step explanation:
We will utilize the standard form of an exponential function, given by:
[tex]f(t)=a(r)^t[/tex]
In the case of half-life, our rate r will be 1/2. This is because 1/2 or 50% will be left after t half-lives.
Our initial amount a is 185 grams.
So, by substitution, we have:
[tex]\displaystyle f(t)=185\big(\frac{1}{2}\big)^t[/tex]
Where f(t) denotes the amount of grams left after t half-lives.
We want to find the amount left after 6 half-lives. Therefore, t = 6. Then using our function, we acquire:
[tex]\displaystyle f(6)=185\big(\frac{1}{2}\big)^6[/tex]
Evaluate:
[tex]\displaystyle f(6)=185\big(\frac{1}{64}\big)\approx2.89\approx 3[/tex]
So, after six half-lives, there will be approximately 3 grams left.

Which one of these is NOT a step used when constructing an inscribed hexagon using technology? (5 points)
Connect the point with a line through the center of the circle.
Mark the points of intersection between the two circles.
Create another circle with the same radius as the original.
Create a circle using the center with given point tool.
Answer:
the answer is A, connect the point with a line through the center of the circle
Step-by-step explanation:
Create another circle with the same radius as the original. Technology doesn't require this step. Lines, intersections, and circles with the centre and provided point are the steps.
When building an inscribed hexagon with technology, this step is skipped: Make a circle with the same radius as the first.
The following steps are used to build an inscribed hexagon: Create a circle using the centre with a point tool to illustrate the circumscribed circle.
Connect the point with a line through the circle's centre to create its diameter.
Mark the intersections of the two circles (the hexagon's vertices).
Form the inscribed hexagon by connecting the marked spots.
The typical method for building an inscribed hexagon does not involve making a circle with the same radius.

y +3 = -2(x +4)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
For your given point and slope, this is ...
y -(-3) = -2(x -(-4))
y +3 = -2(x +4)
What is the slope in slope-intercept form for this graphs?
Answer:
Step-by-step explanation:
since the line crosses the y axis at -4 we know that b in the slope intercept form is -4 . now we just need the slope.. and slope is rise over run or y/x... soooo .....
looking at the graph I see that the point (-1,4) and (0,-4) look like they are points on the graph..
soooo....
the rise is -8 when the run is 1 or -8/1 or just -8
use the slope intercept form y = mx + b
y= -8x + (-4)
y = -8x -4 :)

Step-by-step explanation:
Given the expression
[tex]\frac{4}{5}x\:-\:\frac{1}{4}x\:=\:11[/tex]
The L.C.M of 5,4: 20
Multiply by LCM = 20
[tex]\frac{4}{5}x\cdot \:20-\frac{1}{4}x\cdot \:20=11\cdot \:20[/tex]
