2x² - 1x = 5x
2x² - 1x - 5x = 0
2x²-6x=0
2x(x-3)=0
2x = 0     or    x-3 = 0
x = 0              x = 3

Answer: x=0,  x=3

Elimination<br>3x +2y=9<br>3x ty=0<br>1​
muminat

Answer:

y = 9

x = -3

Step-by-step explanation:

Given

3x + 2y = 9

3x + y = 0

Required

Solve by elimination

To do this, we subtract both equations (to eliminate x)

3x + 2y = 9

- 3x + y = 0

--------------------

3x - 3x + 2y - y = 9-0

y = 9

Substitute y = 9 in 3x + y = 0

3x + 9 = 0

Solve for 3x

3x =- 9

Solve for x

x = -9/3

x = -3

suppose you drop a tennis ball from a height of 14 feet. After the ball hits the floor, it rebounds to 80% of its previous heigh
NemiM [27]
This is a geometric sequence of the form:

a(n)=ar^n, a=initial value, r=common ration, n=term number, if we relabel it for h(b) we have

h(b)=14(0.8^b)

h(3)=14(0.8^3)

h(3)≈7.2 ft (to nearest tenth of a foot)

177 square cm

Step-by-step explanation:

The radius is half the diameter, so r=7.5 cm. Substituting into the formula for the area of a circle, A=\pi r^2=\pi(7.5)^2 \approx 177 square cm.
