Answer:

f(2) = 7/4

Step-by-step explanation:

f(x) =  \frac{2x + 7 -  {x}^{2} }{4}  \\ f(2) =  \frac{2(2) + 7 -  {2}^{2} }{4}  \\ f(2) =  \frac{4 +  7- 4}{4}  \\ f(2) =  \frac{7}{4}

How many solutions are there to the equation below?
elena55 [62]

Answer:

A) 0 (no solutions)

Step-by-step explanation:

Solve the equation:

3x - 10(x+2) = 13 - 7x

3x - 10x -20 = 13 - 7x

-7x - 20 = 13 - 7x

-20 = 13

Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.

Hi!
solniwko [45]

Answer:

y = 1x - 4

Step-by-step explanation:

You have to solve for the x intercept on the equation

2x-5y=8\\2x-5(0)=8\\2x=8\\x=4\\(4,0)

That is the x intercept for that equation.

Then solve for the y intercept on the equation

4x-3y=12\\4(0)-3y=12\\-3y=12\\y=-4\\(0,-4)

That is the x intercept for that equation.

Use that to find slope for point slope form

\frac{y_{2}-y_{1}}{x_{2}-_{1}} \\\\\frac{-4-0}{0-4} \\\\\frac{-4}{-4} \\\\1

1 is the slope

and slope makes B the y intercept so the equation is

y = 1x - 4
