Answer:

we just did this in class a few weeks ago in pretty sure its 3 because that's where the line crosses the y axis but im not 100 percent sure good luck!❤

Answer:

y=-1x+3, slope intercept is 3

Step-by-step explanation:

Slope: rise/run

(0,3) (3,0)

Plug it in

3-0= 3

0-3=-3

Slope is -1

y=mx+b

B is the y at the 0, in this case, its 3

y=-1x+3

The simplified expression

Romashka-Z-Leto [24]

Answer:

$5x^2 y^2$

Step-by-step explanation:

We need to use the properties shown below to solve this:

1. $\sqrt[n]{x^a} =x^{\frac{a}{n}}$

2. $\sqrt{x}\sqrt{x} =x$

3. $\sqrt{x} \sqrt{y}=\sqrt{x*y}$

Area of a triangle is given by 1/2 * base * height, so we do that and simplify:

$A=\frac{1}{2}(\sqrt{5x^3} )(2\sqrt{5xy^4} )\\A=\frac{1}{2}(5x^3)^{\frac{1}{2}}*2*(5xy^4)^{\frac{1}{2}}\\A=\sqrt{5}x^{\frac{3}{2}}*\sqrt{5}\sqrt{x} } y^2\\A=\sqrt{5} \sqrt{5}x^{\frac{3}{2}} x^{\frac{1}{2}}y^2\\A=5*x^2y^2\\A=5x^2 y^2$

Help anyone can help me do this question 3,I will mark brainlest.

malfutka [58]

Answer:

see explanation

Step-by-step explanation:

Calculate the slopes between pairs of the 3 points using the slope formula

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

with (x₁, y₁ ) = (- 9, 3) and (x₂, y₂ ) = (- 3, 9)

m = $\frac{9-3}{-3-(-9)}$ = $\frac{6}{-3+9}$ = $\frac{6}{6}$ = 1

Repeat with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (- 3, 9)

m = $\frac{9-1}{-3-5}$ = $\frac{8}{-8}$ = - 1

If lines are perpendicular then the product of their slopes = - 1 , then

1 × - 1 = -1

Thus there is a right angle between the 2 lines

Then triangle is right- angled
