Answer:

let F=fee; R=hourly rate=1.2F ; N=number of hours

Total charge=F+NR

Total charge=F+N(1.2F)

$470=F+7(1.2F)

$470=F+8.4F

$470=9.4F

$50=F ANSWER 1: Her fee is $50

We see it is the y terms squared so it opens left or right

in form
(y-k)^2=4(p)(x-h)
vertex is (h,k)
and p is distance from focus to vertex, also distance from vertex to directix
if p>0, then it opens to the right and dirextix is to the left of vertex
if p<0, then it opens to the left and directix is tothe right of vertex


so
(y-1)^2=4(4)(x-(-3))
vertex is (-3,1)
4>0 so dirextix is to left of vertex
left is in x direction
-3-4=-7
directix is x=-7

iris [78.8K]

Answer:

Step-by-step explanation:

Angle A = 90°

Angle B = 45°

According to the angle sum property

Angle A + Angle B + Angle C = 180°

90° + 45° + Angle C = 180°

Angle C = 45°

As the two angles are equal so the triangle is right angle isosceles triangle.
