If <span>y = –4x – 7, the x-intercept is found by setting y=0 and solving for x:

</span><span>0 = –4x – 7  =>  4x = -7, or   x = -7/4       The x-intercept is (-7/4, 0).

</span><span>The y-intercept is found by setting x = 0 and reading off the value of y:

y = –4x – 7  =>  y = 0 - 7, or y = -7.  The y-intercept is (0, -7).</span>

Write the number in 2 equivalent forms as a​ fraction, decimal, or percent.0.40
KIM [24]

Answer:

2/5 or 40%

Step-by-step explanation:

.40 is 40 hundredths or 40/100

40/100 can be reduced to 20/50 and reduced again to 10/25 and one more time to 2/5

Percentages are fractions out of 100 so 40/100 would be 40%.

Of the 47 plays attributed to a​ playwright, 11 are​ comedies, 20 are​ tragedies, and 16 are histories. If one play is selected
Amanda [17]

The odds against selecting a history are 31/16.

<h3>Define probability.</h3>

Probability is the concept that describes the likelihood of an event occurring. In many situations, it is necessary to foresee how something will turn out in the actual world. We may be aware of the result of an event or not. When this occurs, we state that there is a possibility that the event will occur.

Probability is the ratio of the most likely outcomes to all other possible outcomes of an event. The number of successful outcomes for an experiment with 'n' outcomes may be expressed using the symbol x. The following formula can be used to determine the likelihood of an event.

Probability(Event) = favorable outcome/Total outcome = x/n

Number of playwrights = 47

Number of histories = 16

Therefore, the odds against selecting a history are

(47 - 16) / 16

= 31/16
