Answer:

She spent 2 1/5 of her allowance

Step-by-step explanation:

SOOOO, 3 and 5 multiplied make 15.. Right?

So, what is 1/3 of 15? it's 5

So, what is 2/5 of 15? It's 6

so 5+6=11

Write an equation of the line that passes through (-4,-1) and is perpendicular to the line y=4/3x+6

Sonja [21]

Answer:

$y=-\dfrac{3}{4}x-4.$

Step-by-step explanation:

If needed line is perpendicular to the line $y=\dfrac{4}{3}x+6,$ then its slope satisfies condition

$m\cdot \dfrac{4}{3}=-1\Rightarrow m=-\dfrac{3}{4}.$

Then the equation of needed line will have look

$y=-\dfrac{3}{4}x+b.$

Since this line passes through the point (-4,-1), then

$-1=-\dfrac{3}{4}\cdot (-4)+b,\\ \\-1=3+b,\\ \\b=-1-3=-4.$

Hence, the equation is

$y=-\dfrac{3}{4}x-4.$

Find the slop for the given graph and y-intercept <br><br> I got a pic to lol

Sergeeva-Olga [200]

The slope is rise/run
3 up and 3 to the left: 3/3 = 1
The slope is 1

Assuming graph is 1 units per box and y intercept is (0,y), looking at the graph you can see it’s (0,-1)
The y intercept is (0,-1)
