Answer:
Reason 4Step-by-step explanation:
All the reasons are correct apart from the 4th.
Step 4 involves multiplication of both sides by (2/3). Thee reason given is: "Division property of equality", which is wrong as division is not applicable.
Answer:
Reason 4 is correct I just did the quiz
HELP NOW find the domain h(x)=5x/x+3
Find the range of f(x)=x-2
Step-by-step explanation:
Domain of h(x) is
[tex]\Bbb{R}\backslash\{x=-3\}[/tex]
or equivalently,
[tex](-\infty,-3)\cap(-3,+\infty)[/tex]
since h(x) is undefined everywhere except when x=-3.
The range of f(x) is
[tex]\Bbb{R}[/tex]
or equivalently,
[tex](-\infty,+\infty)[/tex]
A bag contains 8 black marbles, 5 white marbles and 12 red marbles. What is the probability of selecting a red marble, not replacing it, then selecting a white marble?
Answer:
1/10
Step-by-step explanation:
8 black marbles, 5 white marbles and 12 red marbles = 25 marbles
P(red) = red/total = 12/25
Remove the marble
8 black marbles, 5 white marbles and 11 red marbles = 24 marbles
P(white) = white/total = 5/24
P(red, remove,white) = 12/25 * 5/24
=12/24 * 5/25
=1/2 * 1/5
=1/10
Step-by-step explanation:
Total balls = 12 + 5 + 8 = 25 marbles
Probability of getting white marbles = 5/24
Probability of red marbles = 12/24 = 1/2
Now
Probability = 1/2 × 5/24 + 1
Probability = 1/2 × 5/25
Probability = 5/50
Probability = ⅒
You are walking directly away from your house. You are 5 miles away from your house when you start walking, so you can determine your distance from your house by adding 5 to the number of miles you have walked. In the equation below, x represents the number of miles you have walked, and y represents your distance from home in miles.
The relationship between these two variables can be expressed by the following equation:
y=x+5
Identify the dependent and independent variables.
Answer:
y is the dependent variable and x is the independent variable
Step-by-step explanation
The number on the right of the equal sign is always the independent variable and the number on the left is always the dependent variable.
independent variable = dependent variable +5

Two step inequalities
Sketch the angle in standard position.
1. -450°
Answer:
When we draw the angle in what is known as standard position, we put its vertex at the origin, and we draw the initial side of the angle along the positive horizontal axis. ... The amount of that rotation corresponds to the measure of the angle.
Step-by-step explanation:
i think the answer _ 2/60
Please help!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
11. Angle A and B are supplementary (add to 180)
And measure of Angle A is 2x+30 and measure of angle B is 6x-12. All you have to do is make an algebraic expression.
180= (2x+30) + (6x-12)
Then just combine like terms and you get
8x+18=180.. Subtract 18 and you get
8x=162 then divide by 8 and you get
X=20.25
Then plug in the number and you get
180=(2*20.25+30)+(6×20.25-12)
Which is is transferred to
180=(70.5) +(109.5)
Which is 180=180.
The measure of angleA is 70.5°
You can try the other's if you want if not then
9. Value of x is 33.5
10. Measure of angleB 90°
12. Measure of angleA 24°

There is a difference of 5 inches in height between CJ and Eric, but you do not know who
is taller. Let c represent CJ's height, and let e represent Eric's height. Formulate an
absolute value equation to relate the heights.
Step-by-step explanation:
The difference between the height of CJ and Eric is 5 inches. It means the height of CJ is either 5 inches higher or 5 inches lower (-5 inches higher) than Eric.
Therefore, we can set up the equation,
[tex]|c-e|=5[/tex]
Alternatively, if we use CJ as the reference,
[tex]|e-c|=5[/tex]
Please help me please
Answer:
A would be 2
B would be 8
Step-by-step explanation:
It's a little hard to explain, but take the function and put it where the variable is. So, for "A" the equation would be [tex]f(1)=2^1[/tex]

The midpoint M of FG has coordinates (7, 19). Point Fhas coordinates (14, 18). Find the
coordinates of point G.
9514 1404 393
Answer:
G(0, 20)
Step-by-step explanation:
G = 2M -F
G = 2(7, 19) -(14, 18) = (14 -14, 38 -18)
G = (0, 20)
__
Additional comment
This formula for finding the end point from the midpoint and the other end can be derived from the fact that the midpoint is the average of the endpoints.
M = (F+G)/2
2M = F+G . . . . . multiply by 2
G = 2M -F . . . . . subtract F
Read the situations below and determine which relationship is not functional
Situation 1: a cell phone bill to the amount of minutes used
Situation 2: the perimeter of a square to the length of one of the sides of a square
Situation 3: the total amount of money charged monthly on credit cards to the number of credit cards owned
Situation (1,2, or 3) does not represent a function.
This is because..
(1. a cell phone bill is unrelated to the amount of minutes used.)
(2. a given side length of a square could have a range of perimeters.)
(3. the same number of credit cards can have different totals.)

Answer is 3

8x - 5y = 30 + 2x, for x
Answer:
[tex]8x - 5y = 30 + 2x \\ 8x - 2x = 30 + 5y \\ 6x = 30 + 5y \\ \\ x = \frac{30 + 5y}{6} \\ \\ x = \frac{30}{6} + \frac{5y}{6} \\ \\ x = 5 + \frac{5y}{6} [/tex]

Half of the smaller of two consecutive even integers is equal to two more than the larger integer. find both integers Please i will give brainliest ASAP
Answer:
-8 and -6.
Step-by-step explanation:
Let the first even integer be a.
Since the second is a consecutive even integer, it is given by (a + 2).
Half of the smaller (i.e. a) is equal to two more than the larger (i.e. a + 2). In other words:
[tex]\displaystyle \frac{a}{2} = (a + 2) + 2[/tex]
Solve for a:
[tex]\displaystyle \begin{aligned}\displaystyle \frac{a}{2} &= (a + 2) + 2\\ \\ \frac{a}{2} &= a + 4\\ \\ a &= 2a + 8 \\ \\ a &= -8 \end{aligned}[/tex]
In conclusion, the two even, consecutive integers are -8 and -6.

The volume of
the figure is
cubic inches.
6 in
10 in.
8 in.
18 in.
Answer:
2,304in^3
Step-by-step explanation:
The formula for volume is [ b * l * h ]. We can use the values we are given to find the volume of both rectangles then add them both together.
12 * 12 * 6 = 864in^3
18 * 10 * 8 = 1,440in^3
Add them both together.
864 + 1440 = 2,304in^3

Rewrite the equation below so that it does not have fractions.
2 - [tex]\frac{3}{4} x =\frac{9}{10}[/tex]
Answer:
40-15x=18
Step-by-step explanation:
Multiply both sides of 2 - 3/4x = 9/10 by twenty to get
20*2 - 20*3/4*x = 20*9/10
which is 40 - 15x = 18
This should be as far as you need to go, but incase you need to go further,
subtract 40 to both sides
multiply both sides by -1 to get rid of the negatives infront of the x
then divide both sides by 15 to get
x=22/15
and yes, when you solve for x, it is a fraction, but just incase if its needed, I included it. Hope this helps in the future! Let me know if any more questions you have on this problem.
Solve for v in terms of s, t, and u.
S = U-t + V
V = what??
Answer:
[tex]v=s-u+t[/tex]
Step-by-step explanation:
Hi there!
[tex]s=u-t+v[/tex]
Our goal is to isolate v on one side of the equal sign.
Subtract u from both sides:
[tex]s-u=u-t+v-u\\s-u=-t+v[/tex]
Add t to both sides to isolate v:
[tex]s-u+t=-t+v+t\\s-u+t=v\\v=s-u+t[/tex]

Answer:
19, 20, 21
Step-by-step explanation:
You can trial-and-error this where you test each answer out step-by-step or you can graph it and you'll see it will be a line for x = 21 and a shaded region to the left of that (if you get what I mean) and from there, any point on the line x = 21 or any point in the shaded region, will be a viable solution.
Simplifying,
