Answer:
Step-by-step explanation:
The sum of all the internal angles of a convex octagon must equal 1080.
You'll want to add all the angles together and then solve.
[tex](x+55)+(3x+20)+4x+(4x-10)+(6x-55)+(3x+52)+3x+(2x+30) = 1080[/tex]

bob wants to sub 3x + y = 13 into 4x +3y = 6 he needs to do what to get this
Answers
Answer:
x = 6.6, y = -6.8
Step-by-step explanation:
Subtract 3 x from both sides of the equation.
y = 13 - 3x
4x + 3y = 6
Replace all occurrences of y with 13 − 3 x in each equation.
-5x + 39 = 6
y = 13 - 3x
Solve for x in the first equation.
x = [tex]\frac{33}{5}[/tex] or 6.6
Replace all occurrences of x with 6.6 in each equation.
y = [tex]-\frac{34}{5}[/tex] or - 6.8

The appropriate rephrase statement to proof the Pythagorean theorem is
In ΔABC , if ∠B = 90°, then AB² + BC² = AC²
Pythagoras's theorem is used to calculate the sides of a right angle triangle. The formula is represented as follows
c² = a² + b²where
c = hypotenuse
a and b are either adjacent or opposite sides of the triangle.
A right angle triangle is a triangle that has one angle as 90°. Therefore, from the triangle below, the appropriate rephrase statement to proof Pythagoras theorem is as follows:

The time, t, for am ice cube to melt. is inversely proportional to the temperature, T, of the water the ice cube is placed. If it takes an ice cube 2 minutes to melt in 75f water, how long will it take an ice cube of the same size to melt in 80f water?
Answers
Answer:
15/8 minutes
Step-by-step explanation:
The inverse relationship implies the following equation.
[tex]t=\frac{k}{T}[/tex]
where k is a constant.
You are given a t and T that go together, so
[tex]2=\frac{k}{75}[/tex]
This implies that k=150. Now you know that the relationship is
[tex]t=\frac{150}{T}[/tex]
Now substitute 80 for T to get the answer.
[tex]t=\frac{150}{80}=\frac{15}{8}[/tex][tex]t=\frac{150}{80}=\frac{15}{8}[/tex]

It takes an ice cube of the same size to melt in 80f water 15/8 minutes.

3x + 2(4x - 4) = 3
Anyone know the answer?
Answers
Answer:
x=1
Step-by-step explanation:
3x+2(4x-4) = 3
3x+8x-8 = 3
11x-8 = 3
11x = 11
x = 11/11 = 1
The solution for x in the expression 3x + 2 (4x- 4) = 3 is,
⇒ x = 1
The given expression is,
⇒ 3x + 2 (4x- 4) = 3
We can simplify by apply distributive property and combine like term,
⇒ 3x + 2 (4x- 4) = 3
Apply distributive property,
⇒ 3x + 8x - 8 = 3
Combine like term,
⇒ 11x - 8 = 3
Add 8 both side,
⇒ 11x = 3 + 8
⇒ 11x = 11
Divide by 11,
⇒ x = 11 / 11
⇒ x = 1
Therefore, The solution for x in the expression 3x + 2 (4x- 4) = 3 is,
⇒ x = 1

The math SAT score of a high school student graduate can be approximated by S(x)=573-133(0.987), where x is the household income of the student in thousands of dollars per year. What is the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per year, in points per thousand dollars? Round answers to 3-decimal places and do not include units with your answer.
Answers
Answer: 0.907
Step-by-step explanation:
The average rate of change in a function from x= a to x = b is given by :-
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Given: [tex]S(x)=573-133(0.987)^x[/tex]
Then, the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per year will be :
[tex]\dfrac{S(60)-S(40)}{60-40}=\dfrac{573-133(0.987)^{60}-573-133(0.987)^{40}}{20}\\\\=\dfrac{512.34-494.20}{20}\\\\=\dfrac{18.14}{20}\\\\=0.907[/tex]
Hence, the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per yearr= 0.907

Terms/CoefficientsCoordinates (x, y)Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
4x - 3y = -20
-x - 8y = 5
Step 2: Rewrite Systems
-x - 8y = 5
[Addition Property of Equality] Add 8y on both sides: -x = 8y + 5[Division Property of Equality] Divide -1 on both sides: x = -8y - 5Step 3: Redefine Systems

Answer: use y=mx+b
Step-by-step explanation: Every straight line can be represented by an equation: y = mx + b. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
