What’s the maximum value of the function p=2x+3y
Answers
Answer:
x= -3/2y + 1/2 p
Step-by-step explanation:
p=2x + 3y
2x + 3y =P subtract 2x from both sides
3y=P -2x divide both sides by 3 and simplify
y = P/3 - 2x/3

Sketch the graph y=− |x−1|+3 and answer the questions:
b)
What are the coordinates of its vertex?
c)
What are the coordinates of x- intercepts? (theres two)
Answers
Answer: The picture I showed is the sketch of the graph y=-|x-1|+3
b) The coordinates for the vertex is (1,3)
c) One of the coordinates for the x intercepts is (-2,0)
The other is (4,0)
Step-by-step explanation:
b)The vertex is the point I showed in the picture. It's where the graph moves in the opposite direction
c) The coordinates for the intercepts can be determined where the graph hits the x axis. At -2, the graph hits the x axis and at 4 the graph hits the x axis.
X intercepts always have a 0 for its y value of the coordinate. Therefore the coordinates are (-2,0) and (4,0)

What is the annual interest for a principal of $3,500 at a simple annual interest
rate of 2.3%?
Answers
Answer:
Step-by-step explanation:
Given principal p =$3500
Time t =1 year
Rate of interest r =2.3%
So annual interest=p×r×t/100
=3500×2×2.3/100
=7000×2.3/100
=16100/100
=161.
So annual interest is $161

What percent of the cats weight is between 0 and 5.9?
Answers
Answer:
there are 20 cats (male and female) in the catergory of 0.59 and there are 100 cats in total.
so you do 20/100 which is already out of 100 so it is 20%
Answer:
%20
Step-by-step explanation:
start by adding all the cats that are in the row labeled 0-5.9 to find the total number of cats that weigh between 0-5.9 lbs.
8 + 1 + 7 + 4 = 20
now add all the cats in the row labeled Total to find the total number of cats.
10 + 36 + 7 + 47 = 100
Since the total number of cats is 100 we should be able to find the percent very easily.
20/100 as a percent is %20
therefore the percent of cats that weigh between 0 and 5.9 lbs is %20

The first equation of this system is y= x+3.
The second equation of this system is y= 3x-.
The solution of the system is (v.).
Answers
Answer:
The first equation of this system is y =2 x + 3.
The second equation of this system is y = 3x −1 .
The solution of the system is (4,11).
Step-by-step explanation:
PLATO correct
The first equation of this system is y = 2x + 3 while the second equation of this system is y = 3x - 1.
Linear equationA linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
For the first line, using the points (0, 3) and (2, 7):
[tex]y-3=\frac{7-3}{2-0}(x-0)\\ \\y=2x+3[/tex]
For the second line, using the points (0, -1) and (2, 5):
[tex]y-(-1)=\frac{11-(-1)}{4-0}(x-0)\\ \\y=3x-1[/tex]
The first equation of this system is y = 2x + 3 while the second equation of this system is y = 3x - 1.

There are a total of 120 bicycles and tricycles in a shop. There are 302 wheels in allmany bicycles and how many tricycles are in the shop?
Answers
Answer: There are 62 tricycles in the shop.
Step-by-step explanation:
Given: Number of wheels in a bicycle = 2
Number of wheels in a tricycle = 3
Let x = Number of bicycles , y = Number of tricycles.
As per given , we have
x+y =120 (i)
2x+3y=302 (ii)
Multiplying 2 on both sides of (i)
2x+2y=240 (iii)
Subtract (iii) from (ii) , we get
y= 62
Put value of y in (i) , we get
[tex]x+62=120\\\\\Rightarrow\ x=120-62\\\\\Rightarrow\ x= 58[/tex]
Hence, there are 58 bicycles and 62 tricycles in the shop.

Answers
Answer:
x= 17 cm
Step-by-step explanation:
Apply the Pythagorean relationship in this question which is stated mathematically as;
a² + b²= c²
where
a= is the base length, b is the height and c is the hypotenuse
First find length BC , where b= 8 cm and c=10cm and a=?
Hence;
a² + b²=c²
a² + 8²=10²
a²= 10²-8²
a²=100-64 =36
a=√36 = 6 cm
Now find AD=x where AB=8cm , BD = 6+9= 15cm
In this case, a=15 cm , b=8cm , c=?
a² + b²=c²
15² + 8² = c²
225 + 64 = c²
289= c²
√289 = c
17 cm = c = x
