Use the Distributive Property to solve the equation. 3x-5(x-4)=-9+5x+15
Norma-Jean [14]

Answer:

I keep getting no solution

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(x−4)=−9+5x+15

(5)(x)+(5)(−4)=−9+5x+15(Distribute)

5x+−20=−9+5x+15

5x−20=(5x)+(−9+15)(Combine Like Terms)

5x−20=5x+6

5x−20=5x+6

Step 2: Subtract 5x from both sides.

5x−20−5x=5x+6−5x

−20=6

Step 3: Add 20 to both sides.

−20+20=6+20

0=26

Jon is launching rockets in an open field. The path of the rocket can be modeled by the quadratic function h(t) = -16t^2 + 96t,
IrinaVladis [17]
It will reach 80 feet for the second time after 5 seconds.

We set the equation equal to 80 feet:
80= -16t² + 96t

When solving quadratics, we want it equal to 0, so we subtract 80 from both sides:
80-80= -16t² + 96t - 80
0= -16t² + 96t - 80

We use the quadratic formula to solve:
t=\frac{-96\pm \sqrt{96^2-4(-16)(-80)}}{2(-16)}
\\
\\t=\frac{-96\pm \sqrt{9216-5120}}{-32}
\\
\\t=\frac{-96\pm \sqrt{4096}}{-32}
\\
\\t=\frac{-96\pm 64}{-32}
\\
\\t=\frac{-96+64}{-32} \text{ or } 0=\frac{-96-64}{-32}
\\
\\t=1 \text{ or } t=5

Graphs of functions on the interval [−4, 4] are depicted below. For each function, find:
DENIUS [597]

Answer:

a) The domain is the set of the possible values of x.

In the graph, we can see that x goes from - 4 to 4

So the domain is: D = x∈ {-4, 4)

b) The zeros are the points where the graph cuts the x-axis.

Those values are:

x = -2

x = 0

x = 2.

c) The graph is positive if it is above the x-axis and it is negative if it is below the x-axis.

in the interval {-4,0} the graph is bellow the x-axis, so in this interval the function is negative.

in the interval {0, 2} the graph is above the x-axis, so in this interval the function is positive.

in the interval {2, 4} the graph is bellow the x-axis, so in this interval the function is negative.
