Answer 1

Answer:

First we need our slope equation

Y₂-Y₁/X₂-X₁

So we have our equation now lets plug it in

-9+2/-4-3 (we make it a plus for -9+2 because the two minuses cancel out).

So now we have -7/-7 which is 1 because -7 divided by itself is one. Thereby your answer is A. 1

Same thing for question 12

1-5/2-4

-4/-2 which is 2 because -2 goes into -4 two times so your answer is A. 2

Let y be f(x)

[tex]\\ \sf\longmapsto y=4x-12[/tex]

Swipe the values

[tex]\\ \sf\longmapsto x=4y-12[/tex]

Isolate y

[tex]\\ \sf\longmapsto 4y=x+12[/tex]

[tex]\\ \sf\longmapsto y=\dfrac{x+12}{4}[/tex]

[tex]\\ \sf\longmapsto y=\dfrac{1}{4}x+3[/tex]

Hence.

[tex]\\ \sf\longmapsto f^{-1}(x)=\dfrac{1}{4}x+3[/tex]

Let y=f(x)

y=4x-12

Now interchange the variables

x=4y-12

The y we need now

x+12=4y

Divide both sides by 4

y=(x+12)/4

This is the inverse

What multiplied to -24 and adds to -10?

Answers

Answer:

6 × 4 = 25

6 + 4 = 10

hope this helps

Answer:

Step-by-step explanation:

x * y=-21

x+y =-10

we use elimination method to solve

x * y = -21

x + y = -10

x = -11

then replace the y s with -11

x * y = -21

x * -11 =-21

x *-11 + -11 = -21+-11

x = -32

x + y = -10

x +-11 = -10

x + -11--11 = -10--11

x + 0 = -10+11

x = 1

x =1

y = -11

Step-by-step explanation:

5⁴×5² = 5⁶

10⁶/10³ = 10³

so, we have 5⁶/10³ = 15.625

and in scientific notation we have to write the first digit (which is not 0) in front of the decimal point, and the following digits of the number as pairings after the decimal point, and then indicate a multiplication with a power of 10 to tell us the right position of the decimal point in the plain number.

so, 15.625 as plain number is

1.5625 × 10¹ in scientific notation.

therefore option 1 is correct.

A pet store has 15 birds and 75 fish.
In simplest form, what is the ratio of birds to fish in the pet store?
O1/6
O1/5
O5/1
I don't know

Answers

Answer:

1/5

Step-by-step explanation:

For every bird in the store there will be 5 fish.

Because there is 5 times more fish then birds.

Using the ratio concept, the number of birds to fish expressed as a ratio is 1/5

Given the Parameters :

Number of birds = 15 Number of fishes = 75

Ratio of the number of birds to fish can be expressed thus :

Number of birds : Number of fishes

15 : 75

Divide both sides by 15

1 : 5

Hence, the ratio of birds to fish is 1/5
