As a first step, what must be done to both sides of the equation? -5n - -2 = 27? A) divide by 5 B) subtract 2 C) add 2 D) multiply by -5

Answers

Answer 1

Answer: The answer is A) Divide by Five

Answer 2

Answer: Hi I would like to point out that two negatives equal a posture so that equation should look like -5n+2=27 so now what tou want to do is subtact 2 from both sides you are not dividing because you want to find the value of n

Evaluate a÷b a=6.4 and b =0.08

Answers

For this problem, you simply have to plug in a and b into your equation. By this I mean that you have to replace a and b in the first equation with what they tell you. Since a=6.4 and b=0.08, you just have to change the first equation to 6.4÷0.08. You can then solve it out and you will end up getting an answer of 80.

Madison created two functions. For Function A, the value of y is two less than four times the value of x.

The table below represents Function B.
-3,-9
-1,5
1,-1
3,3

In comparing the rates of change, which statement about Function A and Function B is true?

A.

Function A and Function B have the same rate of change.
B.

Function A has a greater rate of change than Function B has.
C.

Function A and Function B both have negative rates of change.
D.

Function A has a negative rate of change and Function B has a positive rate of change.

Answers

Answer:

B. Function A has a greater rate of change than Function B has.

Step-by-step explanation:

Function A.

The value of y is two less than four times the value of x.

This statement can be expressed as

$y=4x-2$

This linear function is expressed as slope-intercept form. Where the slope is

$m=4$

Function B.

This function is represented by the given table.

If you observe, the domain is defined as -3, -1, 1, 3. The range is defined as -9, -5, -1, 3.

The domain values increase two units. Range values increase by 4. So, the ratio or slope of this function is

$m=(4)/(2)=2$

If we compare the ratio of change (or slopes) of both function, we would find that Function A as a doble ratio of change than Function B. In other words, Function A has a greater rate of change than Function B.

Therefore, the right answer is B.

A+b = 30 a:b is equivalent to 2:3. What is a& b

Answers

one way is to use brute force (find bigger equivilent ratios and add them)
2:3

to make them bigger, we multiply both by the same number
2:3
2+3=5 nope

2:3 times 2 to both=4:6
add
4+6=10
we can just add the numbers before multiplying and then multiply after

2+3=5
5 times what=30
divide both sides by 5
6=what
we need to multiply each by 6
2:3 times 6 to both =12:18
12+18=30

a=12
b=18

Final answer:

The given equations are simultaneous equations. We need to find the values of 'a' and 'b'. To do so, we convert the ratio into equation and substitute into the original equation. Then solving will give 'a = 12' and 'b = 18'.

Explanation:

In this question, we are given two simultaneous equations to solve for the unknowns 'a' and 'b'. The given equations are 'a + b = 30' and the ratio 'a:b' is equivalent to '2:3'.

Since the ratio 'a:b' is equal to '2:3', we can consider 'a' to be '2x' and 'b' to be '3x'. Substituting this into the first equation, we get '2x + 3x = 30', which simplifies to '5x = 30'. Solving for 'x', we find that 'x = 6'.

Substituting 'x = 6' into the expressions for 'a' and 'b', we find that 'a = 2*6 = 12' and 'b = 3*6 = 18'. Therefore, the solutions to the equations are 'a = 12' and 'b = 18'.

I think it could be B..not sure though. Please help!

Answers

Taking the slope about different points, we have
$m_(1) = ( y_(2)- y_(1) )/(x_(2)- x_(1)) = (100-63)/(18-12) = (37)/(6) =6 (1)/(6) \n m_(2) = ( y_(2)- y_(1) )/(x_(2)- x_(1)) = (30-88)/(8-16) = (-58)/(-8) =7 (1)/(4)$
The slopes are positive but are not equal, which means that that the association is positive non linear association.
