Answer:x = < 12/7
Step-by-step explanation:
Add 2 to both sides:
7x - 2 (+2) < 10 (+2)
7x < 12
Divide both sides by 7:
7x/7 < 12/7
X < 12/7
The solution to the inequality 7x - 2 < 10 is x < 12/7.
Given that an inequality 7x - 2 < 10 we need to solve the inequality,
we know that,
Inequality in mathematics refers to a mathematical statement that compares two quantities, expressing that one quantity is greater than, less than, or not equal to the other.
Inequality is denoted using various symbols, such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).
To solve the inequality 7x - 2 < 10, we'll isolate the variable x.
Let's start by adding 2 to both sides of the inequality:
7x - 2 + 2 < 10 + 2
Simplifying the expression:
7x < 12
Next, divide both sides of the inequality by 7 to solve for x:
(7x)/7 < 12/7
Simplifying further:
x < 12/7
Therefore, the solution to the inequality 7x - 2 < 10 is x < 12/7.

Calculate the average rate of change over the interval from x=1 to x=3
-2
6
8
12
Answer:
The average rate of change over the given interval is 12
Step-by-step explanation:
Here, we want to calculate the average rate of change over the given interval
Mathematically, we can calculate the average rate of change using the formula below;
f(b) - f(a)/b-a
The f values are same as the y values
Thus, we have it that;
a = 1 and b = 3
f(a) = -5 and f(b) = 19
The average rate of change is thus;
(19-(-5))/(3-1) = 24/2 = 12

Unit 8: Right Triangles & Trigonometry Homework 4: Trigonometry: Ratios & Finding Missing Sides
Answer:
26.69
Step-by-step explanation:
The question lacks the required diagram. Find the diagram attached
The missing side is x;
From the triangle we are given;
Opposite = x
Hypotenuse = 29
Angle of elevation = 67 degrees
Using the SOH CAH TOA identity;
Sin theta = opposite/hypotenuse;
sin 67 = x/29
x = 29sin67
x = 29(0.9205)
x = 26.69
Hence the length of the missing side is 26.69
All trigonometric ratios of triangle PQR were calculated.
In the given right triangle PQR
PR = 14
QR = 50
So, using Pythagoras' theorem
PQ = 48
What are Sine, Cosine, and Tangent of a triangle?Sine of an angle = Opposite side / Hypotenuse
cosine of an angle = Adjacent side/ Hypotenuse
Tangent of an angle = Opposite side/ Adjacent side
So, SinQ = 14/50 =7/25
CosecQ = 1/SinQ = 25/7
CosQ= 48/50 = 24/25
SecQ = 1/CosQ = 25/24
TanQ = 14/48 = 7/24
CotQ = 1/tanQ = 24/7
SinR=24/25
CosecR = 1/SinR= 25/24
CosR=7/25
SecR = 1/Cosr = 25/7
TanR =24/7
CotR = 1/tanR = 7/24
Thus, All trigonometric ratios of triangle PQR were calculated.

The density of a certain material is such that it weighs 9 kilograms for every 7 cubic feet of volume. Express this density in pounds per pint. Round your answer to the nearest hundredth.
Answer:
1.641× 10^-3 pounds/ cubic inch
Step-by-step explanation:
Density= mass / volume
Mass of the material= 9 kilograms
Volume= 7 cubic feet
Density= 9/7= 1.286 kg/ ft^3
Density= 1.286 kg/ ft^3
To Convert to pounds per inch
1 kg/ ft^3 = 0.00128 pound / cubic inch
1.286 kg/ ft^3 = X pounds/ cubic inch
X=( 1.286 × 0.00128)
= 0.0016407087 pounds/ cubic inch
= 1.641× 10^-3 pounds/ cubic inch
Hence,this density in pounds per inch is 1.641× 10^-3 pounds/ cubic inch

Step-by-step explanation:
ahh this is a really tough one :D Does this happen to be an AP math class, Pineapple .. you are in advanced math :O.... good for you :)
sooo what can we set equal
note the lines have the same lenght, therefore the arc length will also be the same, then they give us the other two lengths to make the entire circle , yay
so then just set all the arc lengths equal to 360 °
(3x+ 30) + (3x + 30 ) + 2x + 4x = 360 ( put like terms together )
12x + 60 = 360 ( subtract 60 from both sides )
12x = 300 ( divide both side by 12 )
x = 25
nice we now know X :)

Answer:
f(x)=x+2
Step-by-step explanation:
Pick any two points from the question and plug them into the equation y2-y1/x2-x1. In this case, I picked (0,2) and (1,3). Therefore, the equation will be 3-2/1-0. Simplify this to get 1/1 which is equal to 1. Therefore, the slope is equal to 1. Then pick a point and plug it into the point slope form equation which is y-y1=m(x-x1) where m is the slope. In this case, I picked (0,2). Therefore, the equation will be y-2=(x-0). Simplify this to get y-2=x. You want to isolate y so you have to add 2 to both sides. This will make the equation y=x+2 which is the answer. Therefore, the answer is y=x+2 or f(x)=x+2.
