Answer:
[tex]\displaystyle k = -\frac{1}{8}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]\displaystyle y = kx^3[/tex]
And we want to determine the value of k such that the graph passes through the point (-2, 1).
Hence, when x = -2, y = 1. Substitute:
[tex]\displaystyle (1) = k(-2)^3[/tex]
Simplify:
[tex]\displaystyle 1 = -8k[/tex]
Hence:
[tex]\displaystyle k = -\frac{1}{8}[/tex]

The equation of the line in standard form is 2x - y = 4
How to find the equation of a lineThe equation of a line in standard form is expressed as Ax + By = C
Get the slope of the line passing through (2, 0) and (0, -4)
Slope = -4/-2
Slope = 2
GThe y intercept of the line is -4
Get the equation
y = 2x - 4
y - 2x = -4
-2x + y = -4
2x - y = 4
Hence the equation of the line in standard form is 2x - y = 4

approximate √80 by using perfect squares. 80 is between which two perfect squares.
Answer:
8.94
Step-by-step explanation:
√ 80 is between perfect squares √64 and √81
or between 8 abd 9.
the approximate value is 8 + (80-64)/(81-64) =
8 + 16/17 = 8 + 0.94 = 8.94
The value of √80 is 4✓5 and it's between two perfect square 4 and 9
What are perfect squares?A square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it equals 3² and can be written as 3 × 3.
Examples of perfect squares include 4, 9 , 16 , 25 e.t.c
The value of √80 is calculated by using perfect square.
√80 = √ 16 × √5
= 4√5
Therefore we can say that the value of √80 is 4√5 and these value is between two perfect square 4 and 9.

y = 3/4x + 19/2
Step-by-step explanation:
m = 3/4. point (-6,5)
Point slope form:
y-5=3/4(x- -6)
y -5 = 3/4x + 18/4. 18/4 = 9/2
Y = 3/4x + 9/2 + 5. 5 times 2 plus 9 over 2 = 19/2

Answer:
3y = 60°, 2y = 40° , 4x = 104°, x = 26°, y = 50°
Step-by-step explanation:
Triangle g
180° = 80° + 3y + 2y
100° = 5y
y = 20°
Triangle h
y = 180° - 130°
y = 50°
180° = 4x + x + 50°
130° = 5x
x = 130 / 5
x = 26°

Write the equation of the line described
Step-by-step explanation:
slope = x factor = - 5/2
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
New slope = 2/5 = m
y = mx + b
from the point given y = 2 | x = -4
2 = (2/5 × -4 ) + b
2 = - 1.6 + b
b = 3.6
line equation
