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.

IM NOT PLAYING JUST GIMME THE ANSWER!
A rope 63 feet long is cut into two pieces. One of the pieces is three times longer than the other piece. Which system of equations yields the length of the short rope, s, and the long rope, l?
A) s + l = 63 l = 3s
B) s + l = 63 s = 3l
C) s + l = 63(3) l = 3s
D) s + l = 63(3) s = 3l
The system of equations that yields the length of the short rope, s, and the long rope, l will be A. s + l = 63 l = 3s
Based on the information given in the question, the equation to use will be:
l = 3s ...... i
s + l = 63 ...... ii
Substitute equation i into ii
s + l = 63
s + 3s = 63
4s = 63
s = 63/4
s = 15.75
l = 3s = 3 × 15.75 = 47.25
The correct system of equations yields the length of the short rope, s, and the long rope, l will be;
⇒ s + l = 63
And, l = 3s
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A rope 63 feet long is cut into two pieces.
The length of the short rope = s,
And, The long rope = l
Now,
Let the length of the short rope = s,
And, The long rope = l
Here, The length of rope = 63 feet
So, We can formulate;
⇒ s + l = 63
And, One of the pieces is three times longer than the other piece.
So, We can formulate;
⇒ l = 3s
Thus, The correct system of equations yields the length of the short rope, s, and the long rope, l will be;
⇒ s + l = 63
And, l = 3s

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°

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

f(x) = 2x² + 4x - 5
g(x) = 6x³ - 2x² + 3
(f-g)(x) = f(x) - g(x)

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.

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
