Answer:

y = - x + 9

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 9) and (x₂, y₂ ) = (9, 0) ← 2 points on the line

m = $\frac{0-9}{9-0}$ = $\frac{-9}{9}$ = - 1

the line crosses the y- axis at (0, 9 ) ⇒ c = 9

y = - x + 9 ← equation of line

Answer:

y = -x + 9

Step-by-step explanation:

Slope

m = rise / run
m = -1 / 1
m = -1

Y-intercept

(0, 9) = (0, b)
b = 9

Equation

y = mx + b
y = -x + 9

If the discriminant is negative then the quadratic has

zepelin [54]

Answer:

No real solutions (or has two complex roots)

Step-by-step explanation:

The discriminant, b² - 4ac, is the expression (radicand ) of the quadratic equation:

$x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}$ .

The value of the discriminant determines the nature and the number of solutions given by the quadratic equation.

A discriminant with a negative value (or b² - 4ac < 0 ) means that the quadratic equation has no real solutions or two complex solutions. Quadratic equations with a negative discriminant also have no x-intercepts; thus, its graph will not cross the x-axis.

Brad has two alloys containing copper and silver. Alloy A contains 50% pure silver, and alloy B contains 75% pure silver. He wan

oee [108]

Answer:

I think the answer would be

Alloy A 30%

Alloy B 40%

The reason I say that is because Alloy B has a higher amount of pure silver so yeah

I hope this helps mark me brainliest and tell me if I'm wrong please so Then I could fix it.

P.S. Wegnerkolmp2741o is gonna answer so I would go with his
