The length, l, of the shadow cast by an object varies directly as the height, h, of the object. If k is the constant of variation, which equation represents this situation?
A.
l + h = k
B.
lh = k
C.
l = hk
D.
l = h + k
Answers
Answer:
C. l = hk
Step-by-step explanation:
the equation for direct variation is y = xk (or y/x = k) so you just replace y and x with l and h
The length of the shadow cast l represents by situation l = hk. Hence, option (C) is correct.
What is the linear relation of an equation?An equation has a linear relation if a variable from that equation varies linearly with the other variable.
for example, x is varied linearly with y then we can write
x ∝ y
x = yk where k will be the constant of variation.
Given that length, l is varies directly as the height h
Hence, l = hk will be the correct representation.

is it one to one or onto? why?
Answers
Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = -x² - x + 1
Range of the function has been defined as (-∞, [tex]\frac{5}{4}[/tex] ]
Domain of the function is a set of all real numbers.
From the graph of this function,
At x = -3 and x = 2, value of y = -5
But for one to one functions, every x value should map to a different value of y.
Therefore, function is not one to one.
Since, every value of domain (x-value) maps the range (y-value) in the given range (-∞, [tex]\frac{5}{4}[/tex] ], function will be defined as onto.
Therefore, this function is ONTO, but NOT ONE TO ONE.

If you were to use the substitution method to solve the following system, choose the new
equation after the expression equivalent to x from the second equation is substituted into the
first equation.
2x – 3y = -29
x + 4y = 13 (6 points)
1) 2(4y + 13) – 3y = -29
2) 2(-4y + 13) – 3y = -29
3) 2x - 3(4y + 13) = -29
O4) 2x - 36-4y + 13) = -29
Answers
Answer:
Option 2
Step-by-step explanation:
We will use the substitution method, as the question asks for. The second equation (where x or y is isolated on one side) will be susbstituted as the x or y in the first equation.
2x-3y=-29
x+4y=13
let's isolate x onto one side in the second equation.
Subtract 4y from both sides
x=-4y+13
now we can substitute the expression as x in the first equation
2(-4y+13)-3y=-29
it's the 2nd option

Step-by-step explanation:
Solve the equation:
-4x - 12 = 8
Answers
-4x - 12 = 8
+ 12 +12
-4x = 20
-4 -4
x = -5
To ensure that x equals -5, let's substitute the negative integer with x.
-4 x -5 - 12 = 8
-20 - 12 = 8
8 = 8
Therefore, the answer is x = -5 because we confirmed our answer by substituting x with -5 and solving the equation and got the both sides of the equation equal.
The solution to the equation -4x - 12 = 8 is x = -5.
To solve the equation -4x - 12 = 8, we'll isolate the variable x by performing the necessary steps.
First, we'll add 12 to both sides of the equation to eliminate the constant term on the left side:
-4x - 12 + 12 = 8 + 12
This simplifies to:
-4x = 20
Next, we'll divide both sides of the equation by -4 to isolate x:
(-4x)/-4 = 20/-4
This yields:
x = -5
Hence, the solution to the equation -4x - 12 = 8 is x = -5.
By performing the necessary operations of addition, subtraction, and division, we have determined that x is equal to -5, satisfying the equation. This can be verified by substituting x = -5 back into the original equation and confirming that both sides are equal.
