Answer:
x=2/3 or x=−1/2
Step-by-step explanation:
6x²−x=2
6x²−x−2=2−2
6x²−x−2=0
(3x−2)(2x+1)=0
3x−2=0 or 2x+1=0
x=2/3 or x=−1/2
What percent of the cats weight is between 0 and 5.9?
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

find value of x question number F give step by step solution plz take photo or write step by step answer
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

Step-by-step explanation:
What’s the maximum value of the function p=2x+3y
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)
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%?
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
