Answer: y = 2/5x + 5

Step-by-step explanation:

m = (1-5)/(-5-5) = -4 / 10 = -4 / 10 divided by -2 = 2/5

(0,5) is the y-intercept B = 5

Therefore, y = 2/5x + 5

A recycling center was offering cash for different types of recyclables. For each pound of paper recycled they offered $1.41, fo

IrinaVladis [17]

Answer:

Total amount earn = $31.98

Step-by-step explanation:

Given:

Cost of paper = $1.41

Cost of aluminium = $1.53

Cost of plastic = $0.33

Amount of paper = 5 pound

Amount of aluminium = 15 pound

Amount of plastic = 6 pound

Find:

Total amount earn

Computation:

Total amount earn = ($1.41)(5) + ($0.33)(6) + ($1.53)(15)

Total amount earn = $7.05 + $1.98 + $22.95

Total amount earn = $31.98

A parabola can be drawn given a focus of (6, -7)and a directrix of x=-2. What can be said about the parabola?

Komok [63]

If directrix= -7 and focus = (7,-3) the vertex is the midpoint between (7,-3) and (-7,-3) = (0,-3)

The parabola opens to the right. It's of the form x=a(y+3)^2

to solve for a, plug in another point on the parabola, directly above the focus (7,y) the distance from y to -3 is the same as from 7 to -7 = 14. 14-3 = 11, the point on the parabola is (7,11) plug that in to solve for a

7 = a(11+3)^2= 14^2(a)

a = 7/14^2 = 1/28

the parabola is x = (1/28)(y+3)^2 or

28x = (y+3)^2

the axis of symmetry is y=-3, the line through the focus and vertex and perpendicular to the directrix

the latus rectum is the distance from (7,11) to (7,-17), the two points on the parabola directly above and below the focus.

the parabola opens rightward when the focus is to the right of the directrix

the absolute value of p is the distance from the vertex to the focus or 7

1/4p = a, the coefficient of y^2 = 1/28.

HELP GEOMETRY PLEASE

Alexandra [31]

For each of the problems, twice the angle formed by the chords is equal to half the sum of the angles of the arcs.

So, for the first problem, we have $94 \cdot 2 = x+103$ , so $x = 188 - 103 = 85$ .

For the second, $102 \cdot 2 = x + 118$ , so $x = 204 - 118 = 86$ .

For the last problem, $106 \cdot 2 = x + 88$ , so $x = 212 - 88 = 124$ .
