Yuma needs a singer. Singer A is offering her services for an initial $50 in addition to $20 per hour. Singer B is offering his

hoa [83]

Initial charge charged by the Singer A = $50
Hourly charge of Singer A = $20
Initial amount charged by Singer B = $100
Hourly rate charged by Singer B = $10
Let us assume the time after which both singers will charge the smae amount of money = x
Then
50 + 20x = 100 + 10x
20x -10x = 100 - 50
10x = 50
x = 50/10
= 5
So after 5 hours both Singer A and Singer B will charge the same amount of money. I hope the procedure is clear to you and you can attempt such problems in future without needing any kind of help.

Transform the equation to isolate x:ax=bx + 1 how is the value of x related to the difference of a and b

Airida [17]

Answer:

x = $\frac{1}{a-b}$

Step-by-step explanation:

Given

ax = bx + 1

Collect the terms in x on the left side by subtracting bx from both sides

ax - bx = 1 ← factor out x from each term on the left side

x(a - b) = 1 ← divide both sides by (a - b)

x = $\frac{1}{a-b}$

Which point is on the line that passes through point Z and is perpendicular to line AB? (–4, 1) (1, –2 ) (2, 0) (4, 4)

AlladinOne [14]

For this case we have that if the line that passes through point z is perpendicular to line AB, it is fulfilled that:

$m * m_ {AB} = - 1$

We find the slope of AB:

$m_ {AB} = \frac {y2-y1} {x2-x1}$

We choose the points that go through AB:

(-2.4)

(0, -4)

$m_ {AB} = \frac {-4-4} {0 - (- 2)}\\m_ {AB} = \frac {-8} {2}\\m_ {AB} = - 4$

So:

$m * -4 = -1\\m = \frac {1} {4}$

On the other hand, the point z is (0,2).

Then the cut point with the "y" axis is 2.

The equation of the line is:

$y = \frac {1} {4} x + 2$

We test the points:

(-4,1)

$1 = \frac {1} {4} (- 4) +2\\1 = -1 + 2\\1 = 1$

Is fulfilled

(1, -2)

$-2 = \frac {1} {4} (1) +2\\-2 = \frac {1} {4} +2$

It is not true

(2,0)

$0 = \frac {1} {4} (2) +2$

It is not true

(4,4)

$4 = \frac {1} {4} (4) +2\\4 = 1 + 2$

It is not true

Answer:

Option A
