F(3) if f(x) = 2x + 4

1 answer:

6 0

It would be 10
You substitute “x”for “3” so the equation would be 2(3) + 4. Then you multiply 2 and 3, which is 6. Finally add the 4 to get 10.

a line passes through the point (-3,-5) and has a slope of 5 write an equation in point slope form for this line

Tanzania [10]

Answer:

$y=5x+10$

Step-by-step explanation:

1) Plug numbers into slope formula to find $b$ .

$y=mx+b$

$-5=5(-3)+b$

2) Simplify to find $b$ .

$-5=-15+b$

$10=b$

3) Check work.

$-5=-15+10$

This statement is true.

4) Write equation.

$y=5x+10$

What function equation is represented by the graph?

kupik [55]

the answer would be ...

f(x) = -5/2x + 4

We know this because the constant in this equation, 4, is the y-intercept!

This means that the number without the variable is where the line intersects the y-axis.

Additionally, the slope is called the "rise over run", but in this case it is negative. At the point, 4, on the y-axis, we go down 5 units (the numerator of the slope) and to the right by 2 units (the denominator).

We find ourselves at where the line intercepts the x-axis!

I hope my explanation isn't confusing and that it is helpful! If you have any questions or concerns, message me! :)

Simplify. (-2xy4)^4

IrinaVladis [17]

Step-by-step explanation:

${( - 2x {y}^{4} })^{4}$

$= {( - 2)}^{4} \times {x}^{4} \times { {y}^{4} }^{4}$

$= 16 {x}^{4} {y}^{16}$

The figure shown is made up of 16 equally sized

TEA [102]

12/16 are shaded. 12/16 simplified is 3/4 or 75%.
