Answer:

y=-4/3 + 11

Step-by-step explanation:

1. Find the slope

<u>3-(-1) </u>

-6-(-3)

slope= -4/3

2. Point slope form

y-3=-4/3(x+6)

y-3=-4/3x + 8

  y=-4/3x+11

X varies directly as y. If x is 9 when y is 4, find x when-y is 8.
jeka94

Answer:

see explanation

Step-by-step explanation:

Given x varies directly as y then the equation relating them is

x = ky ← k is the constant of variation

To find k use the condition x = 9 when y = 4

k = \frac{x}{y} = \frac{9}{4} = 2.25

x = 2.25y ← equation of variation

When y = 8, then

x = 2.25 × 8 = 18

If x1 and x2 are the roots of the equation x^2 +5x-3=0, determine the value of x1^2 + x2^2. I know that I have to use vietas for
Arturiano [62]

Answer:

31

Step-by-step explanation:

Given

x² + 5x - 3 = 0

with a = 1, b = 5, c= - 3 , then

sum of roots x₁ + x₂ = - \frac{b}{a} = - \frac{5}{1} = - 5

product of roots = \frac{c}{a} = \frac{-3}{1} = - 3

Now

(x₁ + x₂)² = x₁² + 2x₁x₂ + x₂² , that is

(- 5)² = x₁² + 2(- 3) + x₂²

25 = x₁² - 6 + x₂² ( add 6 to both sides ), then

x₁² + x₂² = 31
