Answer:

A) −3x + y = 3

B) 2x − y = −1 Adding both equations:

-x = 2

x = -2 y = -3

The following graph shows the functions f(x) and g(x): graph of function f of x equals x squared and graph of function g of x eq

kompoz [17]

F(x) = x^2
g(x) = x^2+5
g(x) = f(x)+5

We see that g(x) is basically f(x) but we add on 5. So 5 will go in the blank.

The science club went on a two day field trip. The first day the members paid $60 for Transportation plus $15 per ticket to the

DaniilM [7]

T= Total cost
m= # of members

Total equals $60 fee plus ($15 times # of members) plus $95 fee plus ($12 times # of members)

T= $60 + $15m + $95 + $12m
combine like terms

EXPRESSION:
T= $27m + $155

Hope this helps! :)

The wind is blowing N 35.0 degrees W at 1.60 * 10^2 mph. A plane has an engine speed of 3.20 * 10^2 mph. Where should the pilot

Answer: 24.2° SouthWest

<u>Step-by-step explanation:</u>

First step: DRAW A PICTURE of the vectors from head to tail <em>(see image)</em>

I created a perpendicular from the resultant vector to the vertex of the given vectors so I could use Pythagorean Theorem to find the length of the perpendicular. Then I used that value to find the angle of the plane.

<u>Perpendicular (x):</u>

cos 35° = adjacent/hypotenuse

cos 35° = x/160

→ x = 160 cos 35°

<u>Angle (θ):</u>

sin θ = opposite/hypotenuse

sin θ = x/320

sin θ = 160 cos 35°/320

θ = arcsin (160 cos 35°/320)

θ = 24.2°

Direction is down (south) and left (west)

In remodeling a house an architect finds that by adding the same amount to each dimension of a 15ft by 19ft rectangular room, th

earnstyle [38]

Answer:

Step-by-step explanation:

new length=15+x

width=19+x

then area=(15+x)×(19+x)=285+15x+19x+x²=x²+34x+285 ft²

original area=15×19=285 ft²

then 285+98=x²+34x+285

or

x²+34x-98=0

x²+34x+17²=98+17²

(x+17)²=98+289=387

x+17=√387=3√43

x=3√43-17 ft
