Answer:

Brody purchased 16 songs.

Step-by-step explanation:

Ratio of the number of songs purchased by Brody(B) and Jayliah(J) = 2 : 3

\frac{B}{J}=\frac{2}{3} ------(1)

Similarly ratio of the songs purchased by Jayliah(J) and Sadie(S) = 4 : 5

\frac{J}{S}=\frac{4}{5} -------(2)

If Sadie bought the songs (S) = 30

From equation (2),

\frac{J}{30}=\frac{4}{5}

J = \frac{4\times 30}{5}

J = 24

By substituting the value J = 24 in equation (1),

\frac{B}{24}= \frac{2}{3}

B = \frac{2\times 24}{3}

B = 16

Therefore, number of songs purchased by Brody = 16.

What is the point-slope form of a line with slope 3 that contains the point (2,1)​
Ilya [14]
<h3>Answer: y - 1 = 3(x - 2)</h3>

Explanation:

The point-slope form is this general template

y - y1 = m(x - x1)

We replace m with the given slope 3, so we get to this

y - y1 = 3(x - x1)

Then replace the given point (x1, y1) with (2, 1) to end up with

y - 1 = 3(x - 2)

A circular pond is modeled by the equipment x^2+y^2=225. A bridge over the pond is modeled by a segment of the equation x-7y=-75
makkiz [27]
X² + y² = 225
x - 7y = -75

x = 7y - 75

x² + y² = 225
(7y-75)² + y² = 225
(7y - 75)(7y - 75) + y² = 225
49y² - 525y - 525y + 5625 + y² = 225
50y² - 1050y + 5400 = 0
50(y² - 21y + 108) = 0

y² - 21y + 108 ⇒ (y - 12)(y - 9)

x = 7(12) - 75
x = 84 - 75
x = 9       ⇒ (9,12)

x = 7(9) - 75
x = 63 - 75
x = -12 ⇒ (-12,9)

F(x) =x^2+6x and g(x)=7-x find (f-g)(x) and (f-g)(9)
liq [111]
(f-g)(x) = x²+6x - (7-x)
(f-g)(x) = x² + 6x - 7 + x
(f-g)(x) = x² + 7x - 7

(f-g)(9) = 9² + 7*9 - 7
(f-g)(9) = 81 + 63 - 7
(f-g)(9) = 137
