Sketch the graphs. - 2x + 3y = -1
Answer:
Step-by-step explanation:
y =2/3x + 1/3
slope 2/3
y-intercept: (0 ,1/ 3)
Answer:
Step-by-step explanation:
- 2x + 3y = -1 is the equation of a line
Pick any values for x then find y or for y and then find x;
if you have two points you can draw a line trough those two points.
For example,
pick x= -1 then find y
- 2*(-1) + 3y = -1
2+ 3y = -1
3y = -1-2
y= -3/3
y= -1
First point has the coordinates (-1, -1)
pick y = 1 then find x
- 2x + 3*1 = -1
-2x +3 = -1
-2x = -1-3
-2x = -4
x= -4/-2
x= 2
Second point has the coordinate (2, 1)
Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1

Determine if the leading coefficient of the following function is positive or negative and whether the function has a minimum or maximum vertex point.
Answer:
The function has a negative leading coefficient and a maximum vertex point
Explanation:
This function's leading coefficient is determined by whether it is concave up or concave down, meaning it has an Up and Up end behavior for a positive leading coefficient and a Down and Down end behavior for a negative coefficient.
This function's end behavior is Down and Down, so it must have a negative leading coefficient.
The function has a minimum vertex when the function has a positive leading coefficient and a maximum vertex point when the function has a negative leading coefficient.
This means that the functions vertex is the highest or lowest possible value of the function (the rest of the function continues forever in whichever direction.
This particular function has a maximum vertex as there is no point above the vertex here and the function has a negative leading coefficient.
Answer:
Leading coefficient: negative
Maximum vertex point

the area of a rectangular place mat is 98 inches its length is seven inches longer than the width. find the length and width of the place mat
A
Answer:
width is 7, length is 14
Step-by-step explanation:
x(x+7) = 98
x^2 + 7x = 98
x^2 + 7x - 98 = 0
( x + 14 )( x - 7 ) = 0
x+14=0 results in negative measures
x-7=0 ---> x= 7
width is 7, length is 14

Peter increased the amount of crunches he did from 32 to 36. By what percentage did Peter increase the amount of crunches he completed?
A 30%
B 12.5%
C 20%
D 22.5%
9514 1404 393
Answer:
B 12.5%
Step-by-step explanation:
The percentage change is calculated as ...
% change = ((new value)/(old value) -1) × 100%
= (36/32 -1) × 100% = 1/8 × 100% = 12.5%
Peter increased his crunches by 12.5%.

Using probability concepts, it is found that P(X) = 0.68.
The probabilities given are:
0.22 probability of a person living in Africa.0.08 probability of a person living in North America.0.06 probability of a person living in South America.0.55 probability of a person living in Asia.0.07 probability of a person living in Europe.0.01 probability of a person living in Oceania.Event X is the probability of living in either South America, Asia or Europe, thus it's probability is the sum of these three probabilities, that is:
[tex]P(X) = 0.06 + 0.55 + 0.07 = 0.68[/tex]
Hence, P(X) = 0.68.

Answer:
0.68
explanation:

South America = 0.06
Europe = 0.07
Asia = 0.55
0.06 + 0.07 + 0.55 = 0.68
Snoopy the dog is on a 25-ft long chain that is attached to the back of a barn (see the
picture below). If the chain does not allow him to go past either of the adjacent sides
of the barn, how much space does Snoopy have to roam?
Use pi = 3.14 and round your answer to the nearest tenth.
Answer:
A = 981.3 ft^2
Step-by-step explanation:
Here we're calculating the area of a semicircle of radius 25 ft.
The area of a circle is A = (pi)(r)^2, and that of a semicircle of the same radius is A = (1/2)(pi)(r)^2.
Here pi = 3.14 and r = 25 ft, and so the area/space in question is
A = (1/2)(3.14)(25)^2
A = 981.3 ft^2
The space does Snoopy have to roam is 490.625 square feet.
Given that, Snoopy the dog is on a 25-ft long chain that is attached to the back of a barn.
What is the area of a sector?The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.
The formula for the area of the sector of a circle is /360° (r²) where r is the radius of the circle and is the angle of the sector.
From the attached image, we see that snoopy is at the edge of a circle with the garage taking up a quarter of that circle.
Now, the area of space Snoopy was roaming
= 90°/360° × (3.14 × 25²)
= 1/4 × (3.14 × 625)
= 0.25 × 1,962.5
= 490.625 square feet
Therefore, the space does Snoopy have to roam is 490.625 square feet.

Sum of these two numbers
is 58, and the difference of these two numbers are b.
What are the two numbers?
What is the answer to this problem?
Answer:
Step-by-step explanation:
Let one number=x
Therefore the othernumber=x+b
Since,
x+x+b=58
==>2x+b=58
==>2x=58-b
==>x=(58-b)/2
Therefore the other number is (58-b)/2 + b
