Answer:
x = ∛(-21/6)
Step-by-step explanation:
Multiply both sides by 20 to remove the fractional coefficients:
5x^3 = -108
Divide both sides by 5:
x^3 = -21/6
Then x = ∛(-21/6)

A shadow 12 meters long is cast by a fir tree that is 16 meters tall. What is the length of the shadow cast by a nearby ash tree that that is 8 meters tall?
Write your answer as a whole number or a decimal. Do not round.
Answer: 5 m
Step-by-step explanation:
Given
Length of 16 m fir tree is 12 m
length of the ash tree is 8 m
Suppose x is the length of the ash tree
angle [tex]c[/tex] made by fir and ash tree will be same as shown in figure
[tex]\Rightarrow \tan c=\dfrac{16}{12}=\dfrac{8}{x}\\\\\Rightarrow x=8\times \dfrac{12}{16}\\\\\Rightarrow x=5\ m[/tex]

Find the product 8/6n-4 • (9n^2-4).
An expression can be written in rational form by writing it as a fraction with a denominator of
Answer:
The correct answer is 1 for the first part, and 12n+8 for the second part.
Step-by-step explanation: I got them wrong for you guys. Edge 2021.
The product of the expression given is 12n + 8.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is ([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4)
Multiplying the numerators together,
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (9n² - 4)] / [6n - 4]
= {8 [ (3n)² - (2)² ] } / {6n - 4}
We have an algebraic identity, a² - b² = (a + b) (a - b)
Using this identity (3n)² - (2)² = (3n + 2) (3n - 2)
And the expression in the denominator, 6n - 4 = 2 (3n - 2)
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (3n + 2) (3n - 2)] / [2 (3n - 2)]
The expression 3n - 2 gets cancelled as it lies in both numerator and denominator.
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8(3n + 2)] / [2]
= 4 (3n + 2)
= 12n + 8
Hence the product is 12n + 8.

Brian and sonya each have a container. They mark their containers to show tenths. Brian and sonya both fill their containers with 0.7 units of juice. However, brian has more juice in him container. Explain how this is possible.
Answer:
Step-by-step explanation:
Brian could have more juice than Sonya in actual sense, This is because the representation used, that is the container has been calibrated to show tenth. This means that decimal values of juice in the container will not show explicit volume beyond tenth. Hence the volume will be rounded.
For instance, if the actual volume of juice Brian has Is 0.74 and that owned by Sonya is 0.69. In actual sense, 0.74 > 0.69 . However, if both pour their juice into the calibrated container, Brian's volume will be rounded to the nearest tenth as 0.7 and Sonya's (0.69) will also be rounded to 0.7.
But in actual sense, Brian has more Juice than Sonya.

figure out by using substitution
5x + 2 y = 7
4x + y = 8
Answer:
(3, - 4 )
Step-by-step explanation:
Given the 2 equations
5x + 2y = 7 → (1)
4x + y = 8 → (2)
Rearrange (2) expressing y in terms of x by subtracting 4x from both sides
y = 8 - 4x → (3)
Substitute y = 8 - 4x into (1)
5x + 2(8 - 4x) = 7 ← distribute and simplify left side
5x + 16 - 8x = 7
16 - 3x = 7 ( subtract 16 from both sides )
- 3x = - 9 ( divide both sides by - 3 )
x = 3
Substitute x = 3 into (3) for corresponding value of y
y = 8 - 4(3) = 8 - 12 = - 4
solution is (3, - 4 )

Answer:
y - 3 = -1/2(x-1)
Step-by-step explanation:
Given the coordinates (1, 3) and (5,1). The point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the required point
Get the slope
m = 1-3/5-1
m = -2/4
m = -1/2
Using the point (1,3), substitute
y - 3 = -1/2(x-1)
2(y-3) = -(x-1)
Hence the required equation is y - 3 = -1/2(x-1)
Answer:
y - 3 = -1/2(x-1)
