The solution for the given inequality is x ≥ -6.
What are inequalities in mathematics?A declaration of an order connection between two numbers or algebraic expressions, such as greater than, equal to, less than, less than, or equal to. Either questions or theorems can be used to express inequality problems, and both can be solved using methods similar to those used to solve equations. The triangle inequality, for instance, stipulates that the length of the remaining side of a triangle is more than or equal to the sum of the lengths of any two of its sides. Many of these inequalities, like the Cauchy-Schwarz inequality, are used by mathematical analysis to prove some of its most significant theorems.
Given an equation -3−4x ≤ 21.
Solve for x
-3−4x ≤ 21
add three to both sides
-4x ≤ 24
divide by -4 into both sides (signs will be changed)
x ≥ -6
Therefore solution for the given equation in the form of inequalities is
x ≥ -6.

Which of the following is NOT true about the following equation. y= -4
Answer:
Answer is D.
Step-by-step explanation:
Which is not true?
So, lets assess the answers given to the question.
A. It is the equation of a horizontal line.
Yes, it is. Since there is only one y - value which is y = -4, we can confirm this is the y intercept, so therefore the x value is zero. But it's not the answer we're looking for.
B. It's slope is zero, yes the slope is zero. It only lists the y-intercept which confirms that the slope is 0.
C. Yes, I mean i can't really explain how. Just use desmos calculator, the graph is exactly perpendicular.
D. The line actually does cross the x-axis, -4 is the y intercept and the x value is 0, and zero is still a point. So D is the one which isn't correct making it the correct answer.
use a model to divide 5/7 divided by 3 Express the answer in simplest form
Answer:
5/21
You flip the number 3 which will be "1/3", then you multiply that by 5/7 and you get 5/21
Given expression;
We are to divide 5/7 by 3;
Now;
[tex]\frac{\frac{5}{7} }{3}[/tex]
So;
[tex]\frac{5}{7}[/tex] divided by 3
= [tex]\frac{5}{7} x \frac{1}{3}[/tex]
= [tex]\frac{5}{21}[/tex]
The solution is [tex]\frac{5}{21}[/tex]

Carson needs to lease out a music studio to record his new album. The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio. The total amount of money Carson would have to pay to use the studio for tt hours can be determined using the equation P=50t+100.P=50t+100. What is the yy-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
The y-intercept of the equation is 100 and represents the initial studio-use fee.
Step-by-step explanation:
In this equation, our t variable (time) is the equivalent of the x-variable on a graph. This is because it is the variable that we 'change' to see its impact on y. We see how the amount of hours affects the price. So our P variable (price) is the equivalent of y on a graph. The y-intercept is where the line crosses the y-axis on a graph. At this point, x=0.
Since P is our y, and t is our x, to find the y-intercept, we simply need to make t = 0.
P = 50(0) + 100
P = 100
Therefore the y-intercept is 100.
In this context, t represents time, so even though the studio has been used for 0 hours, the price is still 100. This is because the 100 represents the initial studio-use fee, and using it for certain amounts of time adds onto the initial fee of $100. The hourly fee is represented by 50t so it costs $50 more for each hour of use.

Find the lengths of side BC.
Give your answer to 3 significant figures.
Step-by-step explanation:
The perimeter of a rectangle is the sum of all the sides and the width sides are equal, as well as the two length sides.
For this problem that would mean that two sides are equal to BC and two sides are equal to AB.
Since the perimeter (P) is equal to 60 , we can write:
P = 2 * BC + 2 * AB
We can substitute the expressions we are given for AB and BC and 60 for the perimeter:
60 = 2 (2z + 3 ) + 2 (3z + 2)
Using the distributive property and combining like terms, we can find the value of the variable , z:
60 = 4z + 6 + 6z + 4
60 = 10z + 10
Subtract 10 from both sides of the equation:
60 - 10 = 10z + 10 -110
50 = 10z
Divide both sides of the equation by 10:
50/10 = 10z/10
5 = z
Since z = 5, then BC is 2z + 3 or 2*5 + 3
BC = 13

A house is purchased for $150,000 in 2002. The value of the house
depreciates at a rate of 7%. How much is the house worth in 2013? *
Growth:
Decay:
y=a(1+r)*
y= a(1-r)*
a = initial amount before measuring growth/decay
r = growth/decay rate (often a percent)
X = number of time intervals that have passed
9514 1404 393
Answer:
$67,516
Step-by-step explanation:
"Depreciates" means the value is getting smaller. The function that describes the situation is a decay function:
y= a(1-r)^x
Here, a=150000, r = 0.07, and x=11. The value is predicted to be ...
y = 150000(1 -0.07)^11 = 150000(0.93^11) = 67,515.53
The house is worth about $67,516 in 2013.
