5 cm
B

The lowest possible integer value of x is 3 such that (x ≥ 3).
What is referred as the inequalities?An inequality depicts the relationship between two non-equal values in such an algebraic expression. Inequality symbols can indicate that one of the two variables is greater than, greater or equal to, equal to some other value.For the given question;
The area of rectangle A is bigger than the area of rectangle B.
The sides of the rectangle A are 2x-3 and 5 cm.
Area = length×breadth
Area A = (2x - 3)(5)
Area A = 10x - 15
The sides of the rectangle B are x = 2 and 3 cm.
Area = length×breadth
Area B = (x + 2)3
Area B = 3x + 6
As area B > area B
Then,
10x - 15 ≥ 3x + 6
Solving the inequality;
10x - 3x ≥ 6 + 15
7x ≥ 21
x ≥ 3
Thus, the minimum value of the x is 3 to make the area A bigger than Area B.

find the center and foci of the ellipse:
4x^2+9y^2+8x-36y+4=0
The center of the given ellipse is given as (-1, 2)
Center of the Ellipse
To find the center of the ellipse, we need to rearrange the equation into the standard equation of ellipse.
[tex]4x^2 + 9y^2 + 8x - 36y + 4 = 0\\\frac{(x+1)^2}{2} + \frac{(y-2)}{4} = 1[/tex]
The center of the ellipse is given as
[tex]center = (-1, 2)[/tex]
FociThe foci of the ellipse are the reference points in an ellipse and it helps to derive the equation of the ellipse. There are two foci for the ellipse i.e F1 and F2
[tex]F_1= (-1 + \sqrt{5}, 2)\\ F_2 = (-1, -\sqrt{5}, 2)[/tex]

Fine the volume and surface area of the figure below
Answer:
1470 in³, 716 in²
Step-by-step explanation:
The figure is a cylinder, and it's volume can be found using the following formula:
Volume of cylinder
= area of circle base ×height
= πr²h
Identify the value of r and h:
From the diagram, the radius (r) is 6 in. while the height (h) is 13 in.
Using the formula,
volume of cylinder
= π(6²)(13)
= 468π
= 1470 in³ (3 s.f.)
The surface area of a cylinder is the total area of all its faces, i.e. the sum of the area of its two circular bases and its curved surface area.
Formula
Surface area of cylinder
= 2πr² +2πrh
Surface area of cylinder
= 2(π)(6²) +2(π)(6)(13)
= 72π +156π
= 228π
= 716 in² (3 s.f.)

Below are graphs of functions over the interval [-4, 4]. Find the following for each function:
The domain
Zeros of the function
Intervals where the function is positive and intervals where it is negative
The positive interval is (0,2) and the negative range is calculated as (-4,0) and (2,4).
A graph is used to show the relationship between variables on a coordinate plane.
The domain of the function is [-4,4].
The zeros are: -2,0 and 2.
The positive interval is between (0,2).
The range of negative values is (-4,0) to (2,4). This is the set of x values in the graph. The graph demonstrates that the x value is between -4 and 4.
Thus, the domain is [-4,4]. The zeros of the function: Where it crosses the x- axis. The graph touches the x-axis when it is at -2,0 and 2. As a result, the function has the following zeros:-2,0 and 2.
Positive interval:
On the graph, positive values range from x = 0 to x = 2.
Consequently, the positive interval is (0,2).
Negative duration:
This is the x values when the function gives a negative result.
The graph shows negative values from x = -4 to x = 0, then from x = 2 to x = 4.
The negative range is therefore (-4,0) and (2,4).
Hence, the positive interval is (0,2) and the negative range is (-4,0) and (2,4).

You deposit $400 into a savings account that earns interest annually. the function g(x) = 400(1.05)x can be used to find the amount of money in the savings account, g(x), after x years. what is the range of the function in the context of the problem? â„ [0, 400] [0, [infinity]) [400, [infinity])
The constant percent rate of change in the case of a deposit of $400 into a savings account is compounded annually.
With an example, what is compound interest?
When you add the interest you have already earned back into your principal balance, you are earning compound interest, which increases your profits. Consider that you have $1,000 in a savings account earning 5% interest annually. If you made $50 in the first year, your new balance would be $1,050.Principal - $400
rate of interest is compounded annually
g(x) = 400( 1.03)ˣ equation 1.
Formula used
A = P( 1 + r )ⁿ
here n = x
Solution:
Putting the value of n, and principal in the formula
A = P( 1 + r )ⁿ ................... equation 2
now comparing both equation 1 and equation 2,
400( 1.05)ˣ = 400( 1 + r )ˣ
( 1.05)ˣ = ( 1 + r )ˣ
1.05 = 1 + r
r = 1.05 - 1
r = 0.05
r % = 0.05 × 100
r % = 5 %
thus, the constant percent rate of change = 5 %

Under his cell phone plan, Logan pays a flat cost of $58 per month and $3 per gigabyte. He wants to keep his bill under $70 per month. Use the drop-down menu below to write an inequality representing gg, the number of gigabytes he can use while staying within his budget.
PLEASE HELPPPP 3
The inequality which can be used to determine the number of gigabytes is 58 + 3x < 70 and the solution is x < 4
How to write and solve an equation which can be used to determine the number of gigabytes?The given parameters are
Flat cost = $58
Rate = $3 per gigabyte
Budget = Under $70
The equation is represented as:
Total cost = Flat cost + Rate * Number of gigabyte
So, we have
y = 58 + 3x
The budget is under 70
So, we have
58 + 3x < 70
Subtract 58 from both sides
So, we have
3x < 12
Divide both sides by 3
So, we have
x < 4
Hence. the inequality which can be used to determine the number of gigabytes is 58 + 3x < 70 and the solution is x < 4

Solving System of Linear Equations GraphicallyFrom the question, we are to determine the number of apples, x, and the number of peaches, y, that Chee bought
From the given information,
She bought $6 worth of apples and peaches
and
Each apple costs $1 and each peach costs $0.50
Then, we can write that
$1 × x + $0.50 × y = $6
x + 0.50y = 6
Also,
She bought 4 times as many peaches as apples
That is,
y = 4x
Now, we will solve the system of equations graphically
x + 0.50y = 6
y = 4x

Answer: If you're solving for the substitution method then your answer would be (1,3)
Step-by-step explanation:
Answer:
x = -4/5
y = 9/5
Step-by-step explanation:
-3y + 2x = -7
8x - 3y = -1
make one of the equations y=....
-3y + 2x = -7
-3y = -7 - 2x
y = (-7 - 2x)/3
now put (-7 - 2x)/3 where y is in the other equation
8x - 3y = -1
8x - 3((-7 - 2x)/3) = -1
8x - 1*(-7 - 2x) = -1
8x + 7 + 2x = -1
solve for x
8x + 7 + 2x = -1
8x+2x = -8
10x = -8
x = -8/10
x = -4/5
now put -8/10 in one of the equations to get what y is
-3y + 2x = -7
-3y + 2(-8/10) = -7
-3y - 16/10 = -7
-3y = -7 + 16/10
-3y = -70/10 + 16/10
-3y = -54/10
y = -54/10 * -1/3
y = 18/10
