42:105 is the answer
finlep [7]3 years ago
3 0
Answers: A & C

Exlanation For A: 42 divided by 6 is 7, and 105 divided by 15 is 7. That is equivalent

Explanation For C: 36 divided by 6 is 6, and 90 divided by 15 is 6. That is also equivalent.

Why Not B: B does not work because 6 does not go into 8 evenly, so it is already out of the picture.

Write a linear equation that passes through the point (2,-9) and has a slope of -5
Anna [14]

Answer:

  • y = -5x + 1

Step-by-step explanation:

<u>Given:</u>

  • The slope m = -5 and point (2, -9)

<u>Use point slope form:</u>

  • y - y₁ = m(x - x₁), where (x₁, y₁) is the given point

<u>So the equation is:</u>

  • y - (-9) = -5(x - 2)
  • y + 9 = -5x + 10
  • y = -5x + 1

The sum of 42 and x is equal to 97.45. What's the equation for the sentence?!! Help!
gogolik [260]

Answer:

X = 97.45 - 42

Step-by-step explanation:

If 42 + X = 97.45, X needs to be 97.45 - 42

you can do the same thing with smaller numbers, for example:

5 + X = 7

7 - 5= 2 and you can check for sure that this is the answer by adding them together 5 + 2= 7 so it's definitely the right answer

so for this question, 97.45- 42 = 55.45 so that's X

you can check that by 55.45 + 42 and if the answer is 97.45 that's the right answer!

I hope that makes sense

What is B-CF?
Sholpan [36]

I'm guessing on the make up of the matrices.
First off let's look at [C][F].
[C]=
[F]=
[C][F]=
where each element of [C][F] comes from multiplying a row of [C] with a column of [F].
Example: First element is product of first row and first column.

.
.
.
Now that we have [C][F], we can subtract it from [B], element by element,


[B]-[C][F]=
[B]-[C][F]=
.
.
.
If this is not how the matrices look,please re-state the problem and be more specific about the make up of the matrices (rows x columns).
Here's an example.
[A] is a 2x2 matrix. A=[1,2,3,4].
The assumption is that [A] looks like this,
[A]=
[B] is a 3x2 matrix. B=[5,6,7,8,9,10]
[B]=
