Alenkasestr [34]

Answer:

f(9)=-22-9(9)+20=-83

Step-by-step explanation:

f(9) means x = 9, Just substitute 9 into the function.

-9(9) = -81

-22-81+20 = -83

Answer:

Slope = -⁵/3

Step-by-step explanation:

See the attachment below. In the attachment, the green line represents the the rise while the red line represents the run of the line.

The slope = rise/run

Rise = 5

Run = 3

Slope = -(5/3)

Slope = -⁵/3 (the slope would be negative because the line slants downwards from your left to the right)

What is the answer (algebra) <br> -(4x + 3x) = 10x - 5
MariettaO [177]

Step-by-step explanation:

-(4x + 3x) = 10x - 5

We would have to multiply the -1 by the 4x and the 3x which is in the bracket.

Though there is no 1 behind the bracket but, behind any bracket there is 1 there even though it's ignored.

So when we multiply -1 by 4x we are going to get;

-4x

And when we multiply -1 by 3x It's going to be;

-3x

We have -3 and -4 because whenever we multiply any positive and negative number the product is negative.

So;

-4x - 3x = 10x - 5

So now, we group like terms;

- 4x - 3x - 10x = -5

So now that we have grouped, we have to add the negative numbers even though there is no addition sign there we would have to add

-17x = -5

So now we divide both sides by;

-17

Which is going to be;

x=

\frac{5}{17}

At a birthday party there were five more girls than boys. If the ratio of girls to boys was 4 to 3,
exis [7]

Let number if boys be x

  • No of girls=x+5

ATQ

\\ \sf\longmapsto \dfrac{x+5}{x}=\dfrac{4}{3}

\\ \sf\longmapsto 3(x+5)=4x

\\ \sf\longmapsto 3x+15=4x

\\ \sf\longmapsto 4x-3x=15

\\ \sf\longmapsto x=15

<h3>Number of girls</h3>

\\ \sf\longmapsto x+5=15+5=20
