Answer:

see explanation

Step-by-step explanation:

Given

- ( $\frac{2}{5}$ )²

The negative is outside the bracket and is not squared, that is

= - $\frac{2}{5}$ × $\frac{2}{5}$

= - $\frac{2(2)}{5(5)}$ = - $\frac{4}{25}$

Given

$\frac{5^3}{3}$ = $\frac{5(5)(5)}{3}$ = $\frac{125}{3}$

The slope of the line below is 0.5. Write the equation of the line in point-slope form, using the coordinates of the labeled poi

Arturiano [62]

The complete question is
The slope of the line below is 0.5 Write the equation of the line in point-slope form, using the coordinates of the labeled point. It's on a number line which is (3,-3) Do not use parenthesis on the y side.

we know that

Point slope form is
y - y₁ = m(x - x₁) 

Where m= slope and (x₁, y₁) is a point on the line
Plug in m = 0.5 and point (3, -3)
y-(-3)=0.5*(x-3)------> y+3=0.5*(x-3)

the answer is
 y+3=0.5*(x-3)

Fraction of the shape shaded on these two shapes??

xxTIMURxx [149]

The one of the left isn't too tricky, in the bottom left of it you have 1/2 of 1/4 of the shape, and on the bottom right you have 1/4 of 1/4. Imagine the whole shape was cut up like that bottom right bit into 16 triangles, then you would have three of them shaded (see my diagram).

The one on the right seems like guesswork to me, so I'm sorry if I'm wrong. It look like you just have to use your eyes to work out how much of the bottom half of the shape is shaded: looks like 1/16 to me (i.e. you can draw four of those along and four down, again, see my diagram.) So plus the top half, which is 8/16, you get 9/16.

Answers: left picture: 3/16.
right picture: 9/16.
