The equation of a circle is pi(2x+3)^2
What is the least possible integer value of x for the circle to exist? Please explain.
Answer: x = -1
Step-by-step explanation:
The radius needs to be positive, so 2x + 3 > 0. Solving for x, we get x > -3/2. The smallest integer larger than -3/2 is -1, so x = –1.

What is 3^2+(8-2)•4-6/3
First, start by subtracting 8 from 2. Then, square the three. Your equation will then be 9+6 x 4- 6/3. Multiply the first 6 and the four, then divide the second six by 3. The new equation will be 9+24-2. Solve from there, and your answer should be 31.

17% of what number is 3.4
Answer:
20
Step-by-step explanation:
We already have our first value 3.4 and the second value 17. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
Step 1 ---> 3.4 = 17% × Y
Step 2 ---> 3.4 = 17/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 17 we will arrive at:
Step 3 ---> Y = 3.4 × 100/17
Step 4 ---> Y = 3.4 × 100 ÷ 17
Step 5 ---> Y = 20
Finally, we have found the value of Y which is 20 and that is our answer.
*You can easily calculate 3.4 is 17 percent of what number by using any regular calculator, simply enter 3.4 × 100 ÷ 17 and you will get your answer which is 20*which explicit formula describes the sequence

does the following represent a function that can be represented using the equation =+? how would do you know
Answer: It's not a function because the line is curved, and it has an exponent in the equation which makes the line curved instead of straight which will make x repeat.

use the leading coefficient and the degree of the polynomial function to determine the end behavior of the graph. f(x) = 3x^2 - 3x^5 - 14x - 2x^3 - 5
leading coefficient:
degree:
end behavior left or right side:
Answer:
end behavior on left: function goes to + infinity
end behavior on the right: function goes to - infinity
Step-by-step explanation:
You look at the highest powered x term.
You look at the highest powered x-term which is - 3x^5. The polynomial will begin and end the same way a -x^5 curve begins and ends.
end behavior on the left side (as x approaches negative infinity), y values approach positive infinity. You can substitute negative values of x (-1, -5, -10, -100 . . .) in - 3x^5 and you will get increasing positive values for y as you use x values that approach negative infinity).
end behavior on the right side (as x approaches positive infinity), y values approach negative infinity. Substitute positive values for x (1, 10, 100, 1,000 . . .) in - 3x^5 and you will get decreasing negative values for y.

Answer:
0< x < 2.5
Step-by-step explanation:
For this case we must find the interval for which the function is non-linear.
For this, we must define a linear function.
A linear function is a straight line that is generically:
y=mx+b
We observe that the function is non-linear from x = 0 to x = 2.5
Therefore, the interval for which the function is non-linear is given by:

Segment VY is a midsegment of trapezoid FEDC. Find x.
Answer:
x = 12
Step-by-step explanation:
The midsegment VY is half the sum of the parallel bases , that is
VY = [tex]\frac{EF+CD}{2}[/tex] , then
3x + 18 = [tex]\frac{1}{2}[/tex] (x + 96) ← multiply both sides by 2 to clear the fraction
6x + 36 = x + 96 ( subtract x from both sides )
5x + 36 = 96 ( subtract 36 from both sides )
5x = 60 ( divide both sides by 5 )
x = 12

Answer:
b=240
Step-by-step explanation:
We need to find b. In order to this, we must isolate b.
[tex]-17+\frac{b}{8}=13[/tex]
Add 17 to both sides
[tex]\frac{b}{8}=30[/tex]
Multiply both sides by 8 to remove the fraction
[tex]b=240[/tex]
Answer:
b = 240Step-by-step Solution:
-17 + b/8 = 13=> b/8 = 13 + 17=> b/8 = 30=> 8 x b/8 = 30 x 8=> b = 240Hence, the value of b is 240.

An equation with two variables that makes up a straight line on a coordinate plane.
Lines that have the same slope and never intersect.
1. Slope Intercept Form
2. Linear Equation
A pair of numbers that are used to correspond to a point on a graph where the first number is the xcoordinate and the second number is the y. coordinate.
3. Y-Intercept
4. Quadrant
5. Ordered Pairs
A linear equation in the form y = mx +b, where mis the slope and b is the y intercept
6. Parallel Lines
The point where a graph crosses the y axis
One of the four regions into which the x and y axis separate the coordinate plane.
Graph the line that has a slope of 10 and includes the point (0, 0).
Answer:
See attached graph
Step-by-step explanation:
The equation that has a slope of 10 and intersects (0,0) is:
y = 10x
The slope-intercept form of a straight line equation is y=mx+b, where m is the slope and b the y-intercept (the value of y when x = 0).
In this case:
m = 10
b is 0 since the value of y when x = 0 is 0 (0,0).
See attached graph.
[tex]\huge\fbox{Hi\:there!}[/tex]
We are given the slope of the line and a point that it passes through, so we can use the Point-Slope formula:
[tex]\rm{y-y1=m(x-x1)[/tex]
Where
y1 is the y-coordinate of the point, m is the slope and x1 is the x-coordinate.
In this case:
y1=0
m=10
x1=0
Plug in the values:
[tex]\bf{y-0=10(x-0)[/tex]
Solve:
[tex]\bf{y-0=10x[/tex]
[tex]\bf{y=10x}[/tex]
Now, how to graph the line?
Let's look at its equation.
First of all, it has a y-intercept of 0, which means the line touches the y-axis at (0,0)
Now, what about the slope? The slope is 10.
Thus
We move "up 10, over 1, up 10, over 1" and so on, until we have a line.
Then all we have to do is take a ruler and connect the points.
Hope it helps!
