Given: y = 3x - 4. For what value of x does y equal zero?

2 answers:

7 0

Y = 3x - 4

Set y as 0 to find what x is when y is 0.
0 = 3x - 4

Add 4 to both sides.
4 = 3x

Divide both sides by 3.
1.3333 = x

x = 1.3333 when y = 0.

Check your work.
0 = (3)1.3333 - 4
0 = 4 - 4
0 = 0
This is correct.

So the answer is x is 1.3333, which is 4/3 (four thirds), when y is 0.

X = 4/3 because set y=0.
so 0=3x-4. add 4 to both sides so
4=3x. divide both sides by. 3 and you get x=4/3.

Answer:

C. 7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

distance = speed × time

300t = 350(t -1)

300t = 350t -350 . . . . eliminate parentheses

350 = 50t . . . . . . . . . . add 350-300t

7 = t . . . . . . divide by 50

The trip out took 7 hours.

The function h is defined by h (y) = 2y-7. What is the value of h(8) ? ooo

kozerog [31]

Answer:

The value of h(8) = 9

Step-by-step explanation:

Given function as

h(y) = 2y - 7

For y = 8

Put the value of y in given function

So, h(8) = 2 (8) - 7

OR , h(8) = 16 - 7

∴ h(8) = 9

Hence the value of h(8) = 9 Answer

Neko [114]

The correct question is
Teresa graphs the following 3 equations: y=2x, y=x2+2, and y=2x2. She says that the graph of y=2x will eventually surpass both of the other graphs. Is Teresa correct? Why or why not?

we have that
y=2x
y=x²+2
y=2x²

using a graph tool
see the attached figure

We can affirm the following
the three graphs present the same domain-----> the interval (-∞,∞)

The range of the graph y=2x is the interval (-∞,∞)

The range of the graphs y=x²+2 and y=2x² is the interval [0,∞)

therefore
Teresa is not correct because the graph of y = 2x will not surpass the other two graphs since in the interval of [0, infinite) the three graphs present the same range
