14)A compound inequality is [tex]10>x\geq 65[/tex]

15)A compound inequality is [tex]65\% <x< 100\%[/tex]

16)A compound inequality for the temperatures at which mercury in nonliquid. is [tex]-38^{\circ} F>x> 673.8^{\circ}F[/tex]

Step-by-step explanation:

14)

Let x be the age of person

We are given To receive a discount, a person must be under 10 years old, or 65 years or older.

So, [tex]x<10[/tex] or [tex]x \geq 65[/tex]

So, a compound inequality is [tex]10>x\geq 65[/tex]

15) Let x be the percentage scored

We are given that The scores on the last test ranged from 65% to 100%.

So,[tex]65\% <x< 100\%[/tex]

So, a compound inequality is [tex]65\% <x< 100\%[/tex]

16)

Let x be the temperature

We are given that Mercury is nonliquid for temperatures less than -38°F or greater than 673.8°F

So,[tex]x< -38^{\circ} F[/tex] or [tex]x > 673.8^{\circ}F[/tex]

[tex]-38^{\circ} F>x> 673.8^{\circ}F[/tex]

So, a compound inequality for the temperatures at which mercury in nonliquid. is [tex]-38^{\circ} F>x> 673.8^{\circ}F[/tex]

Answer:

y=1x+3

Step-by-step explanation:

y=kx + m

k= y2-y1 / x2- x1

pick two of them, so for example (-2,5) and (0,3)

k=(3-5)/(0-2)= -2/-2= 1

Now we want to know the m . That is by inserting a point in the equation . y=kx+m.

so I'll pick (0,3)

3=1×0+m

m=3

Try with another one to see if you get the same answer.

this time I'll pick (-2,5)

5=1×-2+m

m=3

We can try with (2,5) so that it get used too.

5=1×2+m

m=3

The right equation will therefor be

y=1x+3

Answer:

y=|x|+3

Answer:

-600

Step-by-step explanation:

3*(-4)=(-12)

(-12)*(-10)=120

120*(-5)=(-600)

Answer:

Step-by-step explanation:

4/40    = 0.1

12/100 = 0.12

3/18     = 1.6666

1/5       = 0.2

9/27​    = 0.3333

There are many property in mathematics like Reflexive Property, Substitution Property or Addition Property. Therefore option A is correct option

According to reflexive property,  for every real number x , x=x. According to substitution property, if  x=y , then we can replace y with x in any equation or expression. According to additive property if we add zero to any number then we get the same number back. According to subtraction property if we substract zero from any number we get the same number back

JK+LM=NP+LM

According to our questions, since LM is same on both sides of equations so same thing can be cancelled out on the left and right hand side of equation so LM can be cancelled from both side

Hence we are left with

JK=NP

This property is called reflexive property. Therefore option A is correct option

Answer:

Step-by-step explanation:

There is no unit on this 3 3/4 figure, so my assumption here is that velocity is given in furlongs per fortnight.

A furlong is one eighth of a mile, so Alex is walking 18 furlongs.

18 furlongs / 3.75 furlongs per fortnight gives us 4.8 fortnights. A fortnight is 2 weeks, so this figure comes to 67 days, 4 hours, and 48 minutes, if Alex does not stop for rest.

Answer:

the answer is c

Step-by-step explanation:

hope this helps!:) i am doing this in algebra right now lol

Relationship between the function and its inverse is that C.The x-intercept of f-1 (x) is the opposite as the slope of x.

The inverse function serves as the function that has operation of f in another form which follows the arrangement of f^{-1}.

Therefore, looking through the graph, we can see that function f^{-1} has the same value as the f(x) in another form which makes it an inverse.

Answer:

$40.40

Step-by-step explanation:

1. Round each decimal to the nearest tenth. Keep in mind that the sum is the answer to an addition problem.

$4.28 = $4.30

$21.35 = $21.40

$14.65 = $14.70

2. Now, all we have to do is add up the three decimals to find the answer.
