Answer:

Choice D

Step-by-step explanation:

For this one I would find if the point lands on the line.

Choice A:

What we have to do is to plug in -4 for x and 4 for y.

[tex]y=2x+10\\(4)=2(-4)+10\\4=-8+10\\4\ne2[/tex]

The point is not on this line so this cannot be it.

Choice B:

We pug what we know again.

[tex]y=\frac{1}{3}x+1\\(4)=\frac{1}{3}(-4)+1\\(4)=-\frac{4}{3}+1\\4\ne-\frac{1}{3}[/tex]

The point is not on this line so it can't be it.

Choice C:

We pug in what we know again.

[tex]y=3x-9\\(4)=3(-4)-9\\(4)=-12-9\\4\ne-21[/tex]

The point is not on this line so it can't be it.

The next one has to be it, but we'll check it just in case.

Choice D:

We plug in what we know again.

[tex]y= \frac{1}{2}x+6\\(4)=\frac{1}{2}(-4)+6\\(4)=-2+6\\4=4[/tex]

The point is on this line so this is the line.

If K is the midpoint of JL, and (JL = 48), then (JK = KL = 24) and (a = 88).

As per the question statement, K is the midpoint of JL, and (JL = 48).

We are required to calculate the values of JK and KL and, also the value of "a" if [KL = (a - 24)].

Since, K is the midpoint of JL, then K divides JL into two equal line segments, JK and KL.

Therefore, lengths of JK and KL will be [tex]\frac{JL}{2}=\frac{48}{2}=24[/tex], i.e., (JK = KL = 24).

Also, since [KL = (a - 24)],

[tex]24 = (a -24)\\or, a = [24-(-24)]\\or,a = (24+24)\\or,a = 88[/tex]

Answer:

am i right or wrong not sure.

Step-by-step explanation:

a=1/2hc+1/2hd

Answer: m=3

Step-by-step explanation:

Distributing the '4' means multiplying it by everything within the parenthesis next to it. That means, in this circumstance, you are multiplying the 'm' and the '4' by the '4' on the outside the parenthesis.

4(m+4)=28

4m+16=28. Subtract the 16 on both sides.

4m=12

m=3

The age of the person who entered the room is 26.

From the information, the ages of the people are

23 , 19 , 12 , 21 , 13. Therefore the addition of the ages will give 88.

When another person entered, the person enters the room, the mean age of the 6 people is now 19. Therefore, the total ages will be:

= 19 × 6

= 114

Therefore, the age of the last person will be:

= 114 - 88

= 26

Therefore, the age of the person who entered the room is 26.

Answer:

1) 120

2) 24

Step-by-step explanation:

This is a problem involving permutations: the number of different ways you can arrange stuff

If there are n items, n! represents the permutation of n and is given by the formula : 1 x 2 x 3 x........x (n-1) x n also sometimes written in the form
n x (n-1) x (n-2) x........x 3 x 2 x 1

In this case there are 5 people. So the number of different ways they can stand in line is 5! = 5 x 4 x 3 x 2 x 1 = 120 ways  Answer to (1)

Answer to (2)
If Larry insists on being in the middle the other 4 have to arrange themselves around Larry in 4! ways = 4 x 3 x 2 x 1 = 24 ways

Answer:

D: 32

Step-by-step explanation:

u = (2,-8)

v = (8,-2)

u * v = ((2 * 8) + (-8 * -2))

u * v = (16 + 16)

u * v = 32

Answer:

[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

If I remember correctly, rate of change is basically slope.

So if you want, you can choose two points and use the slope formula. If you're lazy, or don't necessarily NEED to use the slope formula, then you can just choose two points and count the rise and run.

Slope = [tex]\frac{rise}{run}[/tex]

Rise = -2 (going down two)

Run = 3

Therefore the slope is:

[tex]-\frac{2}{3}[/tex]

An equation shows the relationship between variables and other quantities in a situation​, by equating the constraints of the situation.

The variable is the unknown part of the equation that can take any value according to the equation.

Properties of an equation can be defined as-

They are the expression which consist the variables, coefficients of variables and constants having an equal sign in between.

The example of an equation can be given as:

y = 5 x + 10

Lets assume here that the variable (y) represent the charge of taxi and variable (x) represent the number of rides the taxi traveled.

Here the constant 10 is the fixed amount which is charged by the taxi driver and coefficient of (x) 5 is the rate by which the the value of x increases with respect to y.

Therefore, an equation shows the relationship between variables and other quantities in a situation​, by equating the constants of the situation.

Answer:

25x + 15800

Step-by-step explanation:

Given

The amount of money in both banks over time represented  by the functions;

f ( x ) = 50 x + 6500 and  g( x ) = − 25 x + 9300

The total amount of money in the two accounts over time is expressed as;

h(x)= f(x) + g(x)

Substitute;

h(x) = 50 x + 6500 + (− 25 x + 9300)

h(x) = 50x - 25x +6500+9300

h(x) =25x + 15800

Hence the sum of the money in the account over time is 25x + 15800

The rectangular field that has a the perimeter of 134yd has a length of 47yd and width of 20yd

To solve this geometry exercise the equation and procedure we will use is:

P = (2*L) + (2*W)

Where:

Information about the problem:

Applying the perimeter equation of a rectangle, we have:

P = (2*L) + (2*W)

134 = [2*(x+ 27)] + (2*x)

134 = 2x+ 54 + 2x

134 - 54 = 2x + 2x

80 = 4x

x = 80/4

x = 20

Substituting the value of (x) in the data and we have:

W= x

W= 20yd

L= x + 27yd

L= 20yd + 27yd

L= 47yd

The perimeter is the total length of the edge of a geometric figure.

The three consecutive odd numbers in order from smallest to largest are-

Consecutive numbers are numbers which follow each other in a frequent counting order or pattern.

Now, as per the question;

Let the first odd number be 'n'.

Then, the second odd number will be '(n + 2)'.

And, the third odd number will be '(n + 4)'

Now, we have to take the two times the first = 2n.

one times the second  = (n + 2)

three times the third  = 3(n + 4).

Sum of all  three is 296.

Thus,

2n + (n + 2) + 3(n + 4) = 296

Simplifying the equation;

2n  + n + 2 + 3n + 12 = 296

6n = 296 - 14

6n = 282

n = 47 (1st odd number)

n +2 = 47 + 2 = 49 (second odd number)

n + 4 = 47 + 4 = 51 (third odd number)

Thus, the three consecutive odd numbers has be calculated.
