See attachment for the graphs of the inequalities
How to graph the system of inequalities?To do this, we analyze and plot each inequality at a time
Having said that, we have
Inequality 1: y > -3x - 2
Here, we have
y > -3x - 2
The inequality > implies that the right-hand side of the origin will be shaded
Also, it means that the line of the inequality will be a dotted line
Inequality 2: 4x + 5y ≤ 20
Here, we have
4x + 5y ≤ 20
The inequality ≤ implies that the left-hand side of the origin will be shaded
Also, it means that the line of the inequality will be a closed line
Inequality 3: y > -4
Here, we have
y > -4
The inequality > implies that the upper part of the origin will be shaded
Also, it means that the line of the inequality will be a dashed line

(7m³ +8m²-m+2.8)-(-3m³ +9m+3.6)
Answers
Answer:
The correct answer would be,
= 10m^3 + 8m^2 - 10m - 0.8
Step-by-step explanation:
First you subtract the m^3 terms :
> 7m^3 + 3m^3
> 10m^3
Then you subtract m^2 , in this case we only have 1 m^2 :
> 8m^2
Then you subtract the m terms :
> -m - 9m
> -10m
The lastly you subtract the last terms :
> 2.8 - 3.6
> -0.8
= 10m^3 + 8m^2 -10m -0.8
(Make sure to distribute the negative before you solve it.) Just a point!!
Answer:
10m³+8m²-10m-0.8
Step-by-step explanation:
(7m³ +8m²-m+2.8)-(-3m³ +9m+3.6)
Use the sign to open the bracket we have;
7m³ +8m²-m+2.8+3m³-9m-3.6
bring like terms together
7m³+3m³+8m²-9m-m-3.6+2.8
Simplifying we have;

Three angles add up to 180 degrees, angle one has a measure of 8x+8, angle two has a measure of 8x+8 and angle three has a measure of 2x+8.
Given that the sum of the angles is 180 degrees, what is the measure of angle one? Round your answer to the hundredths place IE 79.50.
Answers
The first angle will be 77.33°.
How to calculate the angle?It should be noted that the total angles will be 180°.
This will be illustrated as:
8x + 8 + 8x + 8 + 2x + 8 = 180
18x + 24 = 180
18x = 180 - 24
18x = 156
x = 8.667
The first angle will be
= 8x +8
= 8(8.667) + 8

the difference between compound interest and simple interest on the same sum of rupees 8000 for 2 year is rupees 20 find the rate of interest ?
Answers
Answer:
5%
Step-by-step explanation:
You want the interest rate that makes the difference between compound and simple interest on ₹8000 for two years be ₹20.
Interest formulasThe formula for the value of an account earning simple interest is ...
A = P(1 +rt) . . . . P earning interest rate r for t years
The formula for the value of an account earning compound interest is ...
A = P(1 +r)^t . . . . P earning interest rate r for t years
ApplicationWe want the difference in these amounts over 2 years to be ₹20.
8000(1 +r)^2 -8000(1 +2r) = 20
1 +2r +r^2 -(1 +2r) = 20/8000 . . . . . divide by 8000, expand the square
r^2 = 1/400 . . . . . . simplify
r = 1/20 = 5% . . . . . take the square root
The rate of interest is 5% per year.
Find the equation of the line with slope m=- 3 that contains the point (9, - 15) Use fractions in your response, not decimals
Answers
Answer:
y = - 3x + 12
Step-by-step explanation:
Slope intercept form of line
y = mx + b where m = slope, b = y-intercept
==> y = -3x + b is the equatin
To find b, plug in values for point x = 9, y =-15 and solve for b
-15 = -3(9) + b
-15 = -27 + b
Add 27 both sides
-15 + 27 = b
12 = b
b = 12
Equation is

At a point on the ground 15ft from the base of a tree, the distance to the top of the tree is 1 ft more than 2 times the height of the tree. Find the height of the tree.
The height of the tree is 8ft.
Given that,
A right triangle has two legs, which are height and (15 feet) from the base.
The hypotenuse is 15 feet from the base to the top of the tree.
or 2(height) + 1ft.
Let us take a as height of the tree; b=distance from base=15 ft; c=hypotenuse=2a+1ft
The area of the square created on the hypotenuse of any right triangle is equal to the sum of the areas of the squares formed on the triangle's legs:
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]a^{2} +(15ft)^{2}=(2a+ 1ft) ^{2}[/tex]
[tex]a^{2} +225ft^{2}=4a^{2} +4a+1\\ 0=3a^{2}+4a-224\\ 0=(a-8)\times(3a+28)\\[/tex]

Answers
Numbers that can be written as a power in more than one way is known as exponents .
WHAT ARE EXPONENTS?A sign that denotes raising to a power that is placed above and to the right of a mathematical expression. for example , [tex]2^{a}[/tex].
The mathematical procedure known as exponentiation, abbreviated as bn, involves the base number (b) and the exponent (or power) number (n). In English, it is pronounced "b (raised) to the (power of) n." [1] Exponentiation is the process of repeatedly multiplying bases, where n is a positive integer, and the product is known as bn.
The exponent is typically denoted by a superscript to the right of the base. The term "b raised to the nth power," "b (raised) to the power of n," "the nth power of b," "b to the nth power," or, most simply, "b to the nth," is used to describe bn.
