Answer:

10

Step-by-step explanation:

x = Edith's age = 20 years

y = Ronald's age

x = 20 = y/4

y = 20×4 = 80 years

in z years we have

(x + z) = (y + z)/3

(20 + z) = (80 + z)/3

3(20 + z) = 80 + z

60 + 3z = 80 + z

60 + 2z = 80

2z = 20

z = 10

in 10 years Edith's age will be 1/3 of Ronald's age.

then Edith will be 30, and Ronald will be 90.

30 = 90/3

correct.

F(4) =
Alex787 [66]

Function f(4) = -10 and if g(x) = 2 , x = 0.

To find f(4), we will observe the graph of f(x).

According to the graph of f(x),

when x = 4, y is -10 which means when x is 4 value of f(4) is -10.

To find the value of x when g(x) is 2, we will observe the graph of g(x).

According to the graph of g(x),

when y = 2, x is 0 which means that when x is 0, the value of g(x) is 2.

Hence, f(4) is -10 and x = 0 when g(x) = 2.

I believe the fastest way to solve this problem is to take any two of the given points and to find the slope and y-intercept of the line connecting those two points.  

Let's choose the 2 given points (-3,16) and (-1,12).
Going from the first point to the second, the increase in x is 2 and the increase in y is actually a decrease:  -4.  Thus, the slope of the line connecting these two points is m = -4/2, or m = -2.

Now use the slope-intercept formula to find the y-intercept, b.

One point on the line is (-3,16), and the slope is m = -2.

Thus, the slope-intercept formula y = mx + b becomes 16 = -2(-3) + b.
Here, b comes out to 10.

So now we have the slope and the y-intercept.  Write the equation:

y = mx + b becomes y=-2x+10.  Which of the four given answer choices is the correct one?

A regular pyramid has a regular polygon base and a __over the center of the base
Rufina [12.5K]

Answer: Vertex

Step-by-step explanation:

To solve this exercise you must keep on mind the definitions shown below:

1. By definition, a regular pyramid is a right pyramid whose base is a regular polygon.

2. By definition, a regular polygon is a polygon whose sides have equal lenghts.

3. By definition the apex (which is the vertex at the tip of the pyramid) of a right pyramid lies directly above the center of the base.

Therefore, keeping the above on mind, you can conclude that:

A regular pyramid has a regular polygon base and a Vertex over the center of the base.

A taxicab charges $1.85 for the first quarter-mile and then $0.25 for every quarter mile after the first. The cost for a 17.5 mi
Roman55 [17]

Answer:

$19.10

Step-by-step explanation:

So since he charges $1.85 for the first quarter mile we can keep that as it is for now. If we add 0.25 4 times to make it $1 that would be a mile. We just have to add $17.25 plus the original $1.85 fee
