Answer:
y = (4/3)x.
or in standard form it is
-4x + 3y = 0.
Step-by-step explanation:
The slope m = (8-4) / (6-3)
= 4/3
Using the point-slope form of a line:
y - y1 = m(x - x1)
We use m = 4/3, x1 = 3 and y1 = 4:
y - 4 = 4/3(x - 3)
Multiply through by 3:
3y - 12 = 4(x - 3)
3y = 4x - 12 + 12
3y = 4x
y = (4/3) x
or in standard form it is
-4x + 3y = 0.

18. Nine cartons of juice cost the same as 5 fruit cups. Also, one fruit cup costs 50¢ more than one bowl of soup, while one bowl of soup costs 50¢ more than one carton of juice. What would be the cost of each item: a carton of juice, a fruit cup, and a bowl of soup?
Answer: bowl of soup=$1.75
carton of juice=$1.25
fruit cup=$2.25
Step-by-step explanation:
j=carton of juice. f=fruit cup. s=bowl of soup.
9j=5f
f=s+0.5 ==> 0.5 dollars is 50 cents
s=j+0.5
j=s-0.5
9(s-0.5)=5(s+0.5)
9s-4.5=5s+2.5
4s-4.5=2.5
4s=7
s=7/4
s=$1.75
s=j+0.5
1.75=j+0.5
j=$1.25
f=1.75+0.5
f=$2.25
A lacrosse field is rectangular with a length of 110 yards and a width of 60 yards. Which side lengths could be used to create a scale drawing of the field?
The area of the Lacrosse field with a length of 110 yards and a width of 60 yards is 6600 yard²
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The area of a rectangle is the product of its length and its width. A lacrosse field is rectangular with a length of 110 yards and a width of 60 yards, hence:
Area = length * width = 110 * 60 = 6600 yard²
Scale ratio can be 1:55

Ella measured the height of a in inches every week for four weeks after planting it what is the best prediction for the height of the plant after 12 weeks
Complete question is;
Elle Measured the height of a plant, in inches,Every week for four weeks after planting it.
The height of the plant, h, in inches, Can be modeled by the function h(t) = 1.5t + 3, where t represents the time in weeks.
Based on this model, what is the best prediction for the height of the plant after 12 weeks?
A 16.5 inches
B 21 inches
C 22.5 inches
D 27.3 inches
Answer:
Option B: 21 inches
Step-by-step explanation:
We are given the function h(t) = 1.5t + 3, where t represents the time in weeks.
At t = 0;
h(0): 1.5(0) + 3 = 3inches
At t = 1;
h(1): 1.5(1) + 3 = 4.5 inches
Thus, after 12 weeks, height will be;
h(12): 1.5(12) + 3 = 21 inches

The store is selling lemons at $0.66 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough lemons to make three 9-inch lemon pies,each requiring half a cup of lemon juice
Answer:
It will cost $7.92
Step-by-step explanation:
We will need to find out how many table spoons of lemon we will need first.
We need to make 3 pies requiring half a cup of lemon juice.
3 * 1/2 = 1.5 cups
We convert the cups to tablespoons
1.5 * 16 = 24 tablespoons
Then, since each lemon yields two tablespoons, we divide the tablespoons required by two. This is to find the number of lemons we need.
24/2 = 12
We multiply lemons by the price the store is selling them.
12 * $0.66 = $7.92
This is the price to buy enough lemons to make the 9-inch lemon pies.
Find the circumference of the circle use 3.14 for
Pi Round to the nearest hundred put the answer in cm
Need ASAP if u don’t know the answer don’t answer
Answer:
47.1 cm
Step-by-step explanation:
The circumference of a circle is denoted by C = 2πr, where r is the radius.
Here, we see that the given radius is 7.5, so r = 7.5 cm. We also are given that we need to use the approximation 3.14 for π, so plug all these into the formula:
C = 2πr
C = 2 * 3.14 * 7.5 = 47.1
To round this to the nearest hundredth... well, there's no hundredth place, so we can leave this as is or just write 47.10 cm.
Thus, the circumference is 47.1 cm.
Describe the domain and range.
1. r(x) = | |x|
Domain of r(x) = |x| is ( −∞, ∞ ) , { x | x ∈ R }
Range of r(x) = |x| is [ 0 , ∞ ) , { y | y ≥ 0 }
The domain of a function is defined as the set of values that we are allowed to enter into the function. This set is a bunch of x values in a function such as r(x).
The domain of the given function r(x) is all real numbers except where this expression, r(x) = |x| is undefined. In this question, there is no real number that makes this expression undefined.
The interval is denoted as ( −∞ , ∞ ).
The set builder is denoted as { x | x ∈ R }.
The range of a function is defined as the set of values that the function can assume. This set is a bunch of the values that the function shoots out after we enter a x value in. The range is a set of all valid y values. We have to use the graph to find the range.
The interval is denoted as [ 0 , ∞ )
The set builder is denoted as { y | y ≥ 0 }
Therefore, we get the domain and range as,
Domain of r(x) = |x| is ( −∞, ∞ ) , { x | x ∈ R }
Range of r(x) = |x| is [ 0 , ∞ ) , { y | y ≥ 0 }

Assuming all parabolas are of the form y=ax^2+bx+c, drag and drop the graphs to match the appropriate a-value
9514 1404 393
Answer:
graphs left to right have a=1, a=0.25, a=-1
Step-by-step explanation:
A negative value of 'a' makes the parabola open downward, so the rightmost graph goes with a=-1.
A value of 'a' less than 1 flattens the graph, so the middle graph goes with a=0.25.
A value of 1 gives a standard open-upward parabola, corresponding to the leftmost graph.

Huey is reading a book that is 697 pages long. He tells a friend that he is about 3/4 of the way done. About how many more pages must Huey read before he finishes the book?
is it
A.160
B.175
C.250
D.150
Answer:
B. 175
Step-by-step explanation:
There are 2 ways that we can find the answer to this question:
1. Take 1/4 of 697
2. Take 3/4 of 697 and minus the product from 697.
Let's do it both ways:
If we are doing it the first way it would look like this:
(1/4)(697) = 175
Note that we get 1/4 because Huey already read 3/4 of the book so he has 1/4 left.
The second way would look like this:
(3/4)(697) = 523
679 - 523 = 174 (roughly 175)
Therefore, the answer to your question would be B. 175.
I hope this helps!!

Answer:
x = 8

Step-by-step explanation:
Step 1: Define equation
3(x - 2) = 2(x + 1)
Step 2: Solve for x
Distribute: 3x - 6 = 2x + 2Subtract 2x on both sides: x - 6 = 2Add 6 to both sides: x = 8Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(8 - 2) = 2(8 + 1)Subtract/Add: 3(6) = 2(9)Multiply: 18 = 18Here we see that 18 does indeed equal 18.
∴ x = 8 is a solution to the equation.

The co-ordinates of D is if the midpoint E is at (-1,0 )which is calculated using the section formula.
In coordinate geometry, the Section formula is used to determine the internal or external ratio at which a line segment is divided by a point. It is used to determine a triangle's centroid, incenter, and excentre.
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
The section formula is given by:
[tex]{\displaystyle P=\left({\frac {mx_{2}+nx_{1}}{m+n}},{\frac {my_{2}+ny_{1}}{m+n}}\right)}[/tex]
where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.
The midpoint is calculated by:
[tex]{\displaystyle Q=\left({\dfrac {x_{1}+x_{2}}{2}},{\dfrac {y_{1}+y_{2}}{2}}\right)}[/tex]
where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.
Now the given co-ordinates of the points are C(5, 2) and the midpoint is E(-1 , 0). Now to find the co-ordinates of D we have to use the midpoint formula.
Let the co-ordinate's of D be (a , b) then by using the above midpoint formula we get:
-1 = (5+a) ÷ 2
or, a = -2 -5
or, a = -7
again
0 = (2+b) ÷ 2
or, b = -2
Hence the co-ordinates of D is (-7 , -2)
