-15 so that is negative. so that is negative 15÷15 so 15 ÷15 is 1 so it would be -15÷-15=-1

I AM BEGGING YALL, PLEASE HELP ME OUT​
sweet-ann [11.9K]

Answer:

(2a,2b)

(-4a,b)

Step-by-step explanation:

for the first one

the x value of coordinate L is going to be twice the value of the x coordinate of k (a)

That being said the x value of L = 2a

The y value of L is going to be half the value of the y value of coordinate A ( 4b )

4b/2=2b so the y value of coordinate L is 2b

now we put the values as an ordered pair

The answer would be (2a,2b)

Solve the system of equations by elimination.<br><br> 2x+8y=10<br><br> -4x-9y=-13<br><br> x = y =
Reptile [31]
So use cancelation
multiply first equation by 2
2x+8y=10
times 2
4x+16y=20
now add

4x+16y=20
<u>-4x-9y=-13   +
</u>0x+7y=7
7y=7
divide by 7
y=1

subsittue

2x+8y=10
2x+8(1)=10
2x+8=10
subtract 8 from both sides
2x=2
divide by 2
x=1


x=1
y=1

For f(x)=3x+1 and g(x)=x squared - 6 find (f- g)(x)
saveliy_v [14]
It helps to first clarify that the notation (f - g)(x) simply means f(x) - g(x). Given that, let's look at our f(x) and our g(x) here, and use their definitions to find their difference.

f(x)=3x+1\\g(x)=x^2-6

When we're taking (f - g)(x), we simply substitute the expression 3x + 1 for f(x) and the expression x² - 6 for g(x) to obtain:

(3x+1)-(x^2-6)=3x+1-x^2+6

Or, ordering the polynomial from highest power to lowest and combining the constants:

-x^2+3x+7

Edit: By request, here's what would happen if you had something instead like:

(f\times g)(x)

In this case, you'd have to *multiply* the two function expressions together. Here's what that would look like:

(3x+1)(x^2-6)

Using the distributive property, we can distribute the expression 3x+1 to the terms x^{2} and -6:

(3x+1)x^2-(3x+1)6

Distributing again, we get:

3x(x^2)+x^2-3x(6)+6=3x^3+x^2-18x+6

And we're done.
