A. 2x+y=25; x+y=20
x represents cheese wafers and y represents chocolate wafers.

B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20

Add equations
x=5

Plug x in
5+y=20
y=15

Final answer: 5 cheese wafers, 15 chocolate wafers

What equation is the inverse of y=2x^2-8?
Fynjy0 [20]

Step-by-step explanation:

To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: x = 2y^2 - 8

Solving for y:    

y = 2x^{2} - 8    because  y + 8 = 2x^{2} or  x =\sqrt\frac{y +  8}{2}

So on interchanging the variable, we get the equation:

x = 2y^2 - 8

x + 8 = 2y^2

y = \sqrt\frac{x + 8}{2}

Zigmanuir [339]

Answer:

The distance from the base of the statue to the ship is 771.60 ft

Step-by-step explanation:

Refer the attached figure

Height of statue AB= 250 feet

The tourist sees a ship coming into the harbor and measures the angle of depression as 18°.

So, ∠ACB = 18°

We are supposed to find the distance from the base of the statue to the ship i.e. BC

In ΔABC

Tan \theta = \frac{Perpendicular}{Base}

Tan 18^{\circ}=\frac{AB}{BC}

Tan 18^{\circ}=\frac{250}{BC}

BC=\frac{250}{Tan 18^{\circ}}

BC=\frac{250}{0.324}

BC=771.60 ft

Hence the distance from the base of the statue to the ship is 771.60 ft
