Answer: e(-2,-2) and G(4,6)
Step-by-step explanation:
Solve for x and then find the measure of angle, A.
Answer:
x = 8
The measure of angle A = 30°
Step-by-step explanation:
angle A and B are supplementary and their sum is 180°
6x - 18 + 14x + 38 = 180° add like terms
20x + 20 = 180
20x = 180 - 20
20x = 160 divide both sides by 20
x = 8 and the measure of angle A
6x - 18 ➡ 6 × 8 - 18 = 30°
Kayla has a older sister and a younger sister. her older sister is one year more than twice Kayla's age. Kayla's younger sister is three years younger than she is. the sum of their ages is 26. find Kayla's age
Answer:
x= kaylas age
older sister: 2x+1
younger sister: x-3
x+2x+1+x-3=26
4x-2=26
4x=28
x=7 years old
Step-by-step explanation:
Write the equation of the line that passes through the
point (6,4) and is parallel to 2x + 3y = 18.
The equation of the line that passes through the point (6,4) and is parallel to 2x + 3y = 18 is: y = -2/3x + 8
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that line passes throuthe gh the point (6,4) and is parallel to 2x + 3y = 18.
Parallel lines have the same slope
To Find slope of 2x + 3y = 18
Then Start by putting it in y = mx+b form;
Y = -2/3x + 18
Slope = -2/3x
Y = -2/3x + b
Now Plug in the points into equation
4 = -2/3(6) + b
4 = -4 + b
b = 8
Hence, the Equation: y = -2/3x + 8

10/3
:: 20/3
Answer:
see explanation
Step-by-step explanation:
Use the sine ratio in the right triangle to find the hypotenuse h, and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{20}{h}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
h = 20[tex]\sqrt{2}[/tex]
-----------------------------------------------------------------------------
Use the tangent ratio to find the horizontal leg x and tan45° = 1 , then
tan45° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{20}{x}[/tex] = 1 ( multiply both sides by x )
x = 20

At a basketball game 64% were supporting the visiting team. If total number of people attending h the e game was 2000, how many people were supporters of the home team
Answer:
720
Step-by-step explanation:
0.64 x 2000 = 1280
2000 - 1280 = 720
No. of people supporting the home team out of 2000 people is 720.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, At a basketball game, 64% were supporting the visiting team.
The percentage of people supporting the home team is
(100 - 64)% = 36%.
Now, Total number of people who came to watch is 2000.
∴ No. people supporting the home team is,
= (36/100)×2000.
= 36×20.
= 720 people.

Mr. Scott likes to pose interesting problems to his Mathematics classes. Today,
he started with the expression 6^2020 + 7^2020. He stated that the expression was
not equivalent to 13^2020 and that he was not interested in the actual sum. His
question to his class and to you is, “What are the final two digits of the sum?
Answer:
The last two digits of 6²⁰²⁰ + 7²⁰²⁰ is 7, 7
Step-by-step explanation:
The given question is to find the value of the sum of two numbers 6²⁰²⁰ + 7²⁰²⁰, where, 6²⁰²⁰ + 7²⁰²⁰ ≠ 13²⁰²⁰
We have;
The last two digits of the powers of 6 are;
6¹ = 6, last two digits = 06
6² = 36, last two digits = 36
6³ = 216, last two digits = 16
6⁴ = 1,296, last two digits = 96
6⁵ = 7,776, last two digits = 76
6⁶ = 46,456, last two digits = 56
6⁷ = 279,936, last two digits = 36
6⁸ = 1,679,616, last two digits = 16
6⁹ = 10,077,696, last two digits = 96
6¹⁰ = 60,466,176, last two digits = 76
6¹¹ = 362,767,056, last two digits = 56
Therefore, the last two digits repeat itself every 5 times
For 6²⁰²⁰, the last two digits will be for the 2020/5 = 404 complete times, which will be 76
The last two digits of the powers of 7 are;
7¹ = 7, last two digits = 07
7² = 49, last two digits = 49
7³ = 343, last two digits = 43
7⁴ = 2,401, last two digits = 01
7⁵ = 16,807, last two digits = 07
7⁶ = 117,649, last two digits = 49
7⁷ = 823,543, last two digits = 43
7⁸ = 5,764,801, last two digits = 01
Therefore, the last two digits repeat itself every 4 times
For 7²⁰²⁰, the last two digits will be for the 2020/4 = 505 complete times, which will be 01
Therefore, the last two digits of 6²⁰²⁰ + 7²⁰²⁰ is 76 + 01 = 77, which is 7, 7

Kelly solved an equation: H/ 4 - 11 = 13 using two inverse operations of adding 11 to both sides of the equations, and then dividing both sides by 4. Her answer is H = 6. What is her error?
Answer:
She should have multiplied by 4, not divided
Step-by-step explanation:
Given
[tex]\frac{H}{4}[/tex] - 11 = 13 ( add 11 to both sides ) ← correct
[tex]\frac{H}{4}[/tex] = 24 ( multiply both sides by 4 to clear the fraction )
H = 4 × 24 = 96
H is divided by 4, thus the inverse operation is to multiply

Write a quadratic equation in standard form with the given roots. Show your work to find the equation. -6, 5/2
Answer:
x^2 + 7/2 + 15 is the answer.
Step-by-step explanation:
Make the number that is equal to x be on the side of the x, then multiply those to values.
x = -6
x= 5/2
(x + 6)*(x - 5/2)
Now, distribute the x to the x and the negative 5/2, and add that to 6 distributed to x and negative 5/2. Simplify.

Why is the product of negative reciprocals always -1?
Answer:
please check the explanation.
Step-by-step explanation:
Let suppose we have a number = n
n≠0The negative reciprocal of 'n' = -1/n
Taking the product of 'n' and its negative reciprocal '-1/n':
[tex]n\left(-\frac{1}{n}\right)[/tex]
remove parentheses: (-a) = -a
[tex]=-n\frac{1}{n}[/tex]
[tex]\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}[/tex]
[tex]=-\frac{1\times \:n}{n}[/tex]
[tex]\mathrm{Cancel\:the\:common\:factor:}\:n[/tex]
[tex]=-1[/tex]
Canceling the common factor (the number itself) will bring -1.
It proves that the multiplication of any number and its negative reciprocal will always yield -1.
