How can you tell if a table represents a proportional relationship?
Answer:
from my knowledge i have made a sample here it is:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.

Function w gives the weight of a cat, in kilograms, when it is m months old.
Which statement represents the meaning of the equation w(7) = 4 in this situation?
A) The cat weighs 7 killograms when it is 4 months old.
B) The cat weighs 4 kilograms when it is 7 months old.
C)The weight of the cat has been 7 kilograms for 4 months.
D) The cat weighs 4 kilograms when it is 7 years old.
Option B) The cat weighs 4 kilograms when it is 7 months old. is correct answer.
Given that:w gives weight of cat, in kgs, when it is m months old.
To find:What does w(7) = 4 represents.
Explanation:It is already given that w gives weight in kilograms.
It outputs weight when we tell the age in months, thus, this is what we treat as input.
w(7) means weight when cat is 7 months old.
and w(7) = 4 represents that the cat weighs 4 kilogram when the age of cat is 7 months.
Thus, Option B) The cat weighs 4 kilograms when it is 7 months old. is correct answer.

I need help I would really appreciate it !!
Solve the equation:
-4x - 12 = 8
-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.

Answer:
823/30
or 27 13/30
decimal: 27.43
Step-by-step explanation:
(25+7)+ (1/6 + 2/5)
32+ (5/30 + 12/30)
32+ 17/30
= 32 17/30
60- 32 17/30

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
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

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
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.

Step-by-step explanation:
Challenge # 1
Line has a negative slope with positive slope.
Therefore, equation will be,
y = 1.5x - 6
Parallel line to the given line will have same slope = 1.5 but with different y-intercept.
Equation of the parallel line → y = 1.5x + 6
Challenge # 2
Line has a negative y-intercept = -1 (Approx.)
Slope of the line = negative
Therefore, equation of the line will be,
y = -3.7x -1
Line parallel to the given line will have same slope but different y-intercept.
Equation of the parallel line → y = -3.7x + 1
Challenge # 3
Line with negative slope and no y-intercept.
y = -0.8x
Parallel line to the given line will have same slope and different y-intercept.
Equation of the parallel line → y = -0.8x + 1
Challenge # 4
Line in the graph has positive slope and negative y-intercept.
y = -5 + 4.2x
Line parallel to the given line will have same slope but different y-intercept.
Equation of the parallel line → y = - 7 + 4.2x
is it one to one or onto? why?
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.
