The sum of three times a number and seven is greater than twice the number -4
Answers
Answer: x > -11
Step-by-step explanation:
3x + 7 > 2x - 4
First, we can simplify the right side of the equation by combining like terms:
3x + 7 > 2x - 4
then we can subtract 2x from both sides of the equation:
3x + 7 - 2x > -4
This gives us:
x+7 > -4
then we can add 4 to both sides of the equation:
x + 7 + 4 > 0
This gives us:
x + 11 > 0
then we can subtract 11 from both sides of the equation:
x + 11 - 11 > 0 - 11
This gives us:
x > -11
so the number is greater than -11.

5x - 3y = 7 is in slope intercept form is y = 5/3x - 7/3
How do you write slope intercept form?When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilise the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.
You can utilize two different versions of a line's general form to figure out its equation.
These are the formulas:
1) (y - y1) = m (x – x1), the Point-Slope Formula
2) The formula for slope-intercept, y = mx + b

The two concentric circles shown have diameters a mm and b mm, where a and b are integers with a < b. The gray region between the two circles has area 48π mm2 . What is the sum of all possible values of b?
Answers
The sum of all possible values of b is 124 in the given question.
What is concentric circles?If two or more objects have a common centre, they are said to be concentric in geometry.
Concentric shapes include spheres, circles, regular polyhedral, and regular polygons because they all share a central axis. In Euclidean geometry, concentric circles always have different radii but the same centre.
The difference between the areas is [tex]$ \frac{\pi(b^2 - a^2)}{4} = 48 \pi[/tex]
Therefore b² = a² +1 92
We can write the equation as (b−a)(b+a)=192
So b−a and b+a are factors of 192
Here are the possibilities:
b−a=1, b+a=192 ;
b−a=2, b+a=96 ;
b−a=3, b+a=64 ;
b−a=4, b+a=48 ;
b−a=6, b+a=32 ;
b−a=8, b+a=24 ;
and
b−a=12, b+a=16
Add the pairs of equations and divide by 2 (as long as the sum is even): b=49; b=26; b=19; b=16; and b=14.
49 + 26 + 19 + 16 + 14 = 124

How is the instantaneous rate of change estimated?Adding a very small increment, for example, can help us approximate the instantaneous rate of change at x = a.
The instantaneous rate of change is equal to the slope of the tangent line at a given location. The slope of secant lines can be used to calculate the slope at a point as each secant line's "run" gets closer to zero (the slope of the tangent line).
You can find the instantaneous rate of change of a function by computing the derivative at a specific point and then entering the point's x-value.

m * 0 + c = 2
m * -2 + c = -2
Solving 0 * x + c = 2, we have
c = 2
So, we have

Answers
The team loses 20 people/audience with each loss.
The slope formula defines to the formula used to calculate the steepness of a line and determines how much it's inclined. To calculate the slope of the lines, the x and y coordinates of the points lying on the line can be used.
The formula to calculate slope is:
m = (y2 - y1)/(x2 - x1) = Δy/Δx
When the team lost eight games, 295 people attended the next game.
When the team lost 13 games, 199 people attended the next game.
Slope = 295-199/8-13
slope=100/-5
slope=-20
Therefore, the team loses 20 people/audience with each loss.

what is the distributive property and how do I find it
Answers
Answer: The distributive property is a property where there is a coefficient/number, that is being multiplied to a group of numbers enclosed in parentheses. The coefficient can be distributed/multiplied to the numbers in the parentheses individually or after solving the expression in it.
Step-by-step explanation:
You can spot when the distributive property is used when you see a number in front of a group of numbers, such as these examples (in bold):
1. 4(5 + 6) = 46 , in this problem you can solve 5+6 before multiplying it by 4, or multiply 4*5 and 4*6 and then add it.
2. 2(x-3) = 12 , in this situation x is the unknown variable so you must distribute the 2 individually, so the result would look like: (2*x) + (2*-3) -> 2x - 6 = 12
Show that the two-variable function f given by f(x, y) = 2x^2 − xy is
differentiable at any point (a, b). What is the derivative of f at (a, b)?
Answers
The derivative of f at (a, b) is the gradient vector [4a - b, -a].
How to determine the derivative of f at (a, b)From the question, we have the following parameters that can be used in our computation:
f(x, y) = 2x^2 − xy
The two-variable function f(x, y) = 2x^2 - xy is differentiable at any point (a, b) if its partial derivatives exist and are continuous at that point.
This is represented as
∂f/∂x = 4x - y
∂f/∂y = -x
The derivative of f at (a, b) can be calculated by evaluating the partial derivatives of f at (a, b):
∂f/∂x(a, b) = 4a - b
∂f/∂y(a, b) = -a
Hence, the derivative of f is [4a - b, -a].

Which statements about the functions are true? Check all that apply.

We are given that On a coordinate plane, 2 exponential functions are shown. f (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1.
When evaluated in zero we have:
f(0) = 2(1/2)^0 = 2
So it crosses through the point (0, 2).
And when evaluated in x = 1, then
f(1) = 2(1/2)^1 = 1
Then it also passes through (1, 1). It goes crosses the y-axis at (0, 14) and goes through (1, 5) and (2, 2).
