Answer:
Set up an equation (you can use the distance formula as an equation). The distance formula is Y2-Y1/X2-X1.
2-(-4)/x-5=-3
6/x-5=-3
Multiply both sides by x-5.
6=-3(x-5)
Distribute the -3 to the terms in the parentheses.
6=-3x+15
Subtract 15.
-9=-3x
Divide both sides by -3.
3=x
So, the missing number of the coordinate is 3.

What is the size of the angle, below?
please help me
Answer:
it is an obtuse angle that means it's more than 180°
The size of the given angle is approximately 200°
What is measure of angle?"It is the measurement of the angle formed by the two rays or arms at a common vertex"Angles are measured in degrees using a protractor.
For given question,
We need to find the size of angle.
We know, the sum of all angles on either side of the line is 180°
If we continue the straight line towards right, then the part of the angle above line must be 180°
To find the angle below straight line,
Put the protractor at the vertex of both the line segments and measure the angle.
The angle must be within the range 15° - 25°.
Let the angle below straight line is 20°
So, the total angle is 180° + 20° = 200° (approximate size)
Therefore, the size of the given angle is approximately 200°

A. 24 m x 26 m
B. 25 m x 25 m
C. 50 m x 50 m
D. 50 m x 25 m
Answer:
Step-by-step explanation:
4) B , C and D represents the quadratic equation.
B) width = w
length = l = 2w + 2
Area = 24 square m
l *w = 24
(2w + 2)*w = 24
2w*w + 2w = 24
2w² + 2w - 24 = 0
Divide the entire equation by 2
w² + w - 12 = 0
C) width = w
Length = w + 3
Area = 40 m²
(w + 3 ) *w = 56
w*w + 3*w = 56
w² + 3w - 56 = 0
D) Width = w
Length = w + 8
Area = 40
(w + 8)*w = 40
w² - 8w - 40 = 0
5) B) 25 * 25
25 *25 gives the largest area that has its perimeter 100

Solve for x
Answer:
x = 11°
Step-by-step explanation:
Because of Alternate Exterior Angles, 5x - 12 = 43. Now, let's solve.
=> 5x - 12 = 43
=> 5x = 55
=> x = 11°
Hoped this helped.
Answer:
x = 11
Step-by-step explanation:
Alternate exterior angles are congruent where a transversal crosses parallel lines. That means ...
(5x -12)° = 43°
5x = 55 . . . . . . . divide by °, add 12
x = 11 . . . . . . . . . divide by 5

The measure of the second angle of a triangle is twice the measure of the first. The measure of the third angle is six times the measure of the first. Find the measure of the third angle
Answer:
120°
Step-by-step explanation:
The sum of all angle measurements for the interior of the angle is 180°.
Let the first angle measurement be denoted as "x".
The second angle measurement is twice that of the first, or "2x".
The third angle measurement is six times of that of the first, or "6x".
Set the equation:
x + 2x + 6x = 180
Simplify. Combine like terms. Like terms are terms with the same, as well as same amount of said variable:
(x + 2x + 6x) = 180
(9x) = 180
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 9 from both sides of the equation:
(9x)/9 = (180)/9
x = 180/9 = 20
x = 20
Next, plug in 20 for x for the third measurement:
6x = 6 * (20) = 120°
120° is your answer.

the angles of a triangle are in the ratio of 7:6:2. find the measure of each angle.
A. 84, 72, 24.
B. 56, 48, 16.
C. 90, 80, 10,
D. 42, 36, 12
Answer:
A. 84, 72, 24
Step-by-step explanation:
Let the angles be - 7x 6x and 2x
7x + 6x + 2x = 180° (angle sum property)
15x = 180°
x = 180° ÷ 15 = 12
Therefore, the angles are : 7x = 7 × 12 = 84
6x = 6 × 12 = 72
2x = 2 × 12 = 24

If Mt. Everest was 29,035 ft above sea level in 1999 and has been growing 2.4 inches each year, how tall do you think it should be today?
Step-by-step explanation:
you basically have to multiply 29,035 by 2021 i think
ans=58,679,735
Step-by-step explanation:
29,035 ft in 1999.
today is 2021. the difference is 22 years.
the growth rate is 2.4 inches per year.
so, in 22 years it grew 2.4×22 = 52.8 in
1 ft = 12 in
52.8 in = 4 ft 4.8 in = 52.8/12 ft = 4.4 ft
so, it should be now 29,039.4 ft above sea level.

Step-by-step explanation:
I need help with this question!
Answer:
y=58
x=32
Step-by-step explanation:
two remote interior angle is congruent, equal, to the exterior angle. so 50+88 is equal to y+86. add the two numbers and set the equations equal to each other. 138=y+86. then subtract 86 from both sides. y=58. knowing that y is 58 we can now solve for x. the interior angles of a triangle always equal 180. 58+90, the right angle, equals 148. 180-148=32 therefor x=32

What are the slope and y-intercept of the line?
Question 1 options:
Slope = -2, y-Intercept = -4
Slope = 1, y-Intercept = 2
Slope = -1, y-Intercept = 2
Slope = 2, y-Intercept = -4
The slope of the line is 1 and the y intercept is 2.
The linear equation is given by:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept
Let n represent the number of inches a plant grows after m months.
Taking two points (0, 2) and (6, 8), the equation is given by:
[tex]n-n_1=\frac{n_2-n_1}{m_2-m_!} (m-m_1)\\\\n-2=\frac{8-2}{6-0}(m-0) \\\\n=m+2[/tex]
Therefore the slope of the line is 1 and the y intercept is 2.
