Answer:
Answer:
1.) the y intercept is 490 and the slope is -2/3x
2.) First, I would find the point (0,490) and plot a point there. Then I would use our slope -2/3 to figure out what direction and what angle the line goes by counting 2 down and 3 to the right
3.) f(x)= -2/3x+490
The graph represents how many wraps could've been sold for each number of sandwich sales to keep the same profit of $1,470.
4.) graph down below
5.) the profits are the same (slope) but the y intercept is higher then the original graph.
6.) y=-2/3x+300
Step-by-step explanation:
some of these are part of the problem as well.
1.) 2x+3y=1,470
3y=-2x+1,470
-2x+1,470/3
-2/3x + 490
y=-2/3x + 490
the y intercept is 490 and the slope is -2/3x
2.) First, I would find the point (0,490) and plot a point there. Then I would use our slope -2/3 to figure out what direction and what angle the line goes by counting 2 down and 3 to the right
3.) f(x)= -2/3x+490
The graph represents how many wraps could've been sold for each number of sandwich sales to keep the same profit of $1,470.
5.) 2x+3y=1,593
3y=-2x+1,593
y=-2/3x+531
the profits are the same (slope) but the y intercept is higher then the original graph.
6.) (150, 200) (300, 100)
y intercept= 300
m= 100-200/300-150 = -100/150 = -2/3
y=-2/3x+300
this was a question from a while ago but I thought I would answer it anyways, hope its right and hope it helps you! <3
can someone please explain(ignore the lines i’ve drawn on i don’t think they are
correct)
Answer:
Step-by-step explanation:
1.open the compass more than half of the distance between C and D, and scribe arcs of the same radius centered at C and D.
2. Call the two points where these two arcs meet A and B. Draw the line between A and B.
3. AB is the perpendicular bisector of the line segment CD. Call the point where AB intersects CD E.

Step-by-step explanation:
Find the value of x in the figure below 13x+8 2x+7
Step-by-step explanation:
step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)
step 2. 15x + 15 = 180 (like terms)
step 3. 15x = 165 (subtract 15 from each side)
step 4. x = 11. (divide both sides by 15)

Here is a square inscribed in a circle with radius 1 meter. What is the perimeter of
the square? Explain or show your reasoning
Answer:
[tex]4\sqrt{2}[/tex]
Step-by-step explanation:
distance formula:[tex]\sqrt{\left(x_2-x_1\right)^{2}+\left(y_2-y_1\right)^{2}}[/tex]
set square to be centered on the origin and find the distance between 2 of the connected points
[tex]\sqrt{\left(3-2\right)^{2}+\left(2-1\right)^{2}}[/tex]
= [tex]\sqrt{\left(1\right)^{2}+\left(1\right)^{2}}[/tex]
= [tex]\sqrt{2}[/tex]
multiply by 4 as it is a square and all of its sides are equal
[tex]4\sqrt{2}[/tex]
insert units
[tex]4\sqrt{2}\ \ meters[/tex]
The perimeter of the square is √32.
Given to us
the radius of the circle is 1 meterWhat is the diagonal of the square inscribed in the circle?As we can see in the figure AB is the diagonal of the square and diameter of the circle. therefore,
AB = Diagonal of the square = Diameter of circle = 2 x Radius = 2 meter
We know the diagonal of a square is equal to the product of √2 and the side of the square.
[tex]Diagonal = side \times {\sqrt2}[/tex]
Substitute the value,
[tex]2 = side \times {\sqrt2}\\\\side = \dfrac{2}{\sqrt2}\\\\side ={\sqrt2}[/tex]
What is the perimeter of the square?The perimeter of the square is four times the side of the square.
[tex]Perimeter = 4\times (side)[/tex]
Substitute the value,
[tex]Perimeter = 4\times (\sqrt2)\\\\Perimeter = 4\sqrt2 = \sqrt{2\times 16} = \sqrt{32}[/tex]
Hence, the perimeter of the square is √32.

if x-y=9,x²+y²=27,then xy=?
Answer:
xy = - 27
Step-by-step explanation:
Note that
(x - y)² = x² - 2xy + y² ← substitute given values, that is
9² = 27 - 2xy
81 = 27 - 2xy ( subtract 27 from both sides )
54 = - 2xy (divide both sides by - 2 )
- 27 = xy

Which is a solution to the equation?
(x - 3)(x - 5) = 35
Ox= -8
O x= -5
O x= 2
O x = 10
Answer:
x=10
Step-by-step explanation:
Let's solve your equation step-by-step.
(x−3)(x−5)=35
Step 1: Simplify both sides of the equation.
x2−8x+15=35
Step 2: Subtract 35 from both sides.
x2−8x+15−35=35−35
x2−8x−20=0
Step 3: Factor left side of equation.
(x+2)(x−10)=0
Step 4: Set factors equal to 0.
x+2=0 or x−10=0
x=−2 or x=10

Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplify the radicals
[tex]\sqrt{20}[/tex]

I am having a family reunion this summer. I have $5,000.00 to spend. I will spend $1575.00 for decorations and entertainment. The cator will charge
$26.00 per person. How many people can attend with the given budget. Write and solve an equation, then state how many people can attend the
reunion.
Answer:
The answer is 131 people
Step-by-step explanation:
I'm not too sure about equations bc its been a min since I've done them but maybeeeee it's 26x - (1,575) = 5,000 something like that LOL
All I know is that you have to subtract 1575 from 5,000 and then you get 3,435 dollars left and you divide that by 26 people and you get 131.731 but of course you can't have a half of person so it stays at 131.
Hopefully that helped lol

Doctors sometimes use this formula to calculate how much medicine to give a child. A child who is 4 years old needs some medicine. The amount for an adult is 20 ml. Use the formula to work out the correct amount for this child.
Answer:
A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity
Step-by-step explanation:
Medications are available in multiple concentrations, therefore orders written in "mL" rather than "mg" are not acceptable and require further clarification.
...
Example 2.
Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day
Step 2. Divide the dose by the frequency: 1800 mg/day ÷ 1 (daily) = 1800 mg/dose

Given the equation 4(3n-7) = -19, what is the first step you could use to solve for n?
Answer:
3/4
Step-by-step explanation:
4(3n-7)=-19
3n-7=-19/4
3n=-19/4+7
3n=-19/4+28/4
3n=9/4
n=(9/4)/3
n=(9/4)(1/3)
n=9/12
simplify
n=3/4
Answer:
3/4
You would have to divide both sides by 4
Step-by-step explanation:
[tex]\frac{4(3n-7)}{4} =\frac{-19}{4}[/tex] ( divide both sides by 4 )
[tex]3n-7= -\frac{19}{4}[/tex] ( simplify )
[tex]3n-7+7=-\frac{19}{4} +7[/tex] ( add 7 to both sides )
[tex]3n=\frac{9}{4}[/tex] ( simplify )
[tex]\frac{3n}{3} =\frac{\frac{9}{4} }{3}[/tex] ( divide both sides by 3 )
[tex]n=\frac{3}{4}[/tex]

Step-by-step explanation:
2x - 3 = 7
this equation can represent the senario because the number (x) is doubles (multiplyed by 2), subtracted by 3 then equal to 7
then you can just solve for x
2x=10
x=5
