Answer:

y=-x+1

Step-by-step explanation:

The slope is -1. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y--1)=-1(x-2)

y+1=-x+2

y=-x+1

I will mark brainliest if u answer this question right! REMEMBER TO EXPLAIN ON HOW U KNOW!

Alja [10]

Answer:

Step-by-step explanation:

To calculate how much fence is needed we need to calculate the perimeter NOT area.

P = 2L+2W

P =2(6.75)+2(4 2/3)

P = 13.5 + 9 1/3

P = 22 5/6

Because she only has 22 yards she does not have enough to go all the way around.
Hope this helps and brainliest please

If f(1) = 1 and f(n) = 5f(n-1) + 4 then find the value of f(5).

klasskru [66]

Answer:

$f(5)=1249$

Step-by-step explanation:

Given:

$f(1)=1$
$f(n) = 5f(n-1)+4$

$\implies f(2) = 5f(1)+4=5(1)+4=9$

$\implies f(3) = 5f(2)+4=5(9)+4=49$

$\implies f(4) = 5f(3)+4=5(49)+4=249$

$\implies f(5) = 5f(4)+4=5(249)+4=1249$

What is the discriminant of the quadratic equation 0 = 2x2 3x – 5? –37 –31 43 49

Degger [83]

The discriminant of a quadratic equation is useful in determining the nature of its roots. Further, it can be solved by the equation,
D = b² - 4ac
From the given equation, b = 3, a = 2, and c = -5. Substituting the given to the equation,
D = 3² - (4)(2)(-5) = 49
Thus, the answer is the fourth choice, 49.
