Answer: -2
Step-by-step explanation: 4-8= -4 then it ends up being -2r-4=0
Then you add 4 to 0 so -2r=4 then divide

Vertical Angles Congruence Theorem
Angle Addition Postulate
Definition of Angle Bisector
Answer:
The correct option is;
Angle Addition Postulate;
Step-by-step explanation:
The given two column proof can be presented as follows;
Statement [tex]{}[/tex] Reason
1. ∠PQR is a right angle [tex]{}[/tex] Given
2. m∠PQR = 90° [tex]{}[/tex] Definition of Right Angle
3. m∠PQS + m∠SQR = m∠PQR [tex]{}[/tex] Angle Addition Postulate
4. m∠PQS + m∠SQR = 90° [tex]{}[/tex] Substitution property of equality
5. ∠PQS and ∠SQR are complementary Definition of complementary angles
Given that the angle m∠PQR has angles m∠PQS and m∠SQR arranged adjacent to each other while sharing the same boundary segment, QS we have by the angle addition postulate;
m∠PQR is the sum of the angles m∠PQS and m∠SQR, therefore;
m∠PQR = m∠PQS + m∠SQR = 90°.
Solve the system of equations by graphing:
y= 2x +8
-x+y=0
Answer:
Slope = 4.000/2.000 = 2.000
Slope = 2.000/2.000 = 1.000
Step-by-step explanation:
the first answer is for the first problem and the second answer is for the second problem. Hoped it helped i tried my best.
Solves a systems of linear equations in two variables.
Solve the following systems by graphing
1) 2x + y = 5 and x-3y = - 8
2) 6x - 3y = - 9 and 2x + 2y = -6
Solve the following systems by substitution
3) y = 5x-3 and -x - 5y = - 11
4) 2x - 6 = 24 and x - 5y - 22
Solve the following systems by elimination
5) - 4x - 2y = -2 and 4x + 8y = -24
6) x - y = 11 and 2x + y = 19

Step 1: Define
(6x³ - x⁴ + 7) + (7x⁴ - 3 + 2x²)
Step 2: Simplify
Combine like terms (x⁴): 6x⁴ + 6x³ + 2x² + 7 - 3Combine like terms (Z): 6x⁴ + 6x³ + 2x² + 4Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 3x + 10 y is less than negative 3 over 4 times x minus 1 Part A: Clearly describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points) Part B: Is the point (8, 10) a solution to this system? Explain how you know
Answer:
See attached graph, and answers.
Step-by-step explanation:
The inequalities are given as;
i) y>3x+10
ii) y<-3/4x -1
Graphing the inequalities gives the following result
The solution area is that which is shaded and the lines are broken lines not complete
From the graph the solution is: { -2.9,1.2}
The point {8,10} is not a solution to the system. This is because it is not in the shaded area that represent the solution to the inequalities.

Noah bought a computer cartridge for $28.50. Sales tax on the
cartridge was 6.5%. What was the total amount that Noah paid for the
cartridge? ( I need this answer ASAP)
Total = purchase price x ( 1 + sales tax )
Total = 28.50 x 1.065
Total = $30.35

When a person 6 feet tall casts a shadow
10 feet long, how tall is a nearby tree
which casts a shadow of 45 feet?
Answer:
75 feet
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
Proportion
6 feet man/10 feet shadow = x (tree) / 45 feet (shadow)
6/10 = x /45 Cross multiply
10x = 45*6
10x = 270
x = 270/10
x = 27
The tree is 27 feet long
1) Given that the measure of Angle 2 = 115 degrees and the measure of Angle 8 = 115 degrees, is line m parallel to line p?
Answer:
YES
Step-by-step explanation:
When a transversal cuts two parallel lines, the alternate interior angles are congruent. So, for two lines to be parallel, their alternate interior angles has to be equal.
Angle 2 and angle 8 are alternate interior angles. They both measure 115°. Since these alternate interior angles are congruent, therefore, line m is parallel to line p.

Gabriel is 12 years old, and his younger brother Elias is 2 years old.
How old will each of them be when Gabriel is twice as old as Elias?
Gabriel will be 20, Elias will be 10
We can use an equation to map out and solve for each age.
Years gone by = x
12+x=2(2+x)
12+x=4+2x
x=8
12+8=20, 2+8 =10

Part A Tim wants to buy three pairs of jeans. He compares the prices at a store in his neighborhood and at an online store. He finds that a pair of jeans costs $24 at the local store. If he buys online, each pair would cost $22, and he would have to pay a shipping fee of $6 per order.
Answer:
The pants from the local store would be $72.00
the pants from the online store would be $85.00
the difference in price is $13.00
therefore the pants from the local store would be cheaper
