What is the domain of f(x)? {x|1 {x|1 {yl-4 {y|-4

Mathematics
1 answer:
Paul [167]4 years ago
3 0

Answer:

1\leq x

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The domain of a function is the set of all possible values of x

The domain of the line with negative slope is the interval [1,3)

The domain of the line with slope equal to zero (horizontal line ) is the interval [3,5)

so

The domain of the piece-wise function is the interval [1,5)

1\leq x

The value of x=1 is included in the domain set

The value of x=5 is not included in the domain set

-11.5 -9.5<br><br> How do they compare select the symbol.<br><br> &lt; = &gt;
inn [45]

Answer:

The symbol is <, because -11.5 < -9.5

Step-by-step explanation:

The number line is arranged from smallest to greatest numbers, and when you read the numbers you start from left to right, so the numbers in the left are smaller than the number in the right

In the set of the negative numbers, the greatest value is the smallest number

Examples

-1 is greater than -2  because -2 lies before -1 on the number line

∵ The numbers are -11.5 and -9.5

∵ The number -11.5 is before the number -9.5 on the number line

- That means -11.5 is smaller than -9.5

∴ -11.5 < - 9.5

∴ The symbol is <

Is constructed by making arcs centered at a and b without changing the compass width. which equation is not necessarily true? a.
stich3 [128]

The equation that is not necessarily true is that PQ = AB.

<h3>How to illustrate the equation?</h3>

The perpendicular bisector of any line segment can be drawn by opening the compass more than half, by putting the nib of the compass at one end of a line segment, and by marking an arc on both sides of the line segment from both the ends of the segment.

The following Property that the perpendicular bisector PQ follows when it bisects the line segment AB include:

  • AP=BP
  • AQ=BQ
  • AR=BR
  • ∠ARP=∠BRP=∠ARQ=∠BRQ=90°

Therefore, PQ is Perpendicular Bisector of Line Segment AB is not true.

Need help with this problem
alexandr1967 [171]

Answer:

x = 10

Step-by-step explanation:

Since the triangles are similar the ratios of corresponding sides are equal

\frac{20}{20+8} = \frac{3x}{4x+2}, that is

\frac{20}{28} = \frac{3x}{4x+2} ( cross- multiply )

20(4x + 2) = 84x

80x + 40 = 84x ( subtract 80x from both sides )

40 = 4x ( divide both sides by 4 )

x = 10
