The quantities x and y are proportional. Use each of the integers 1-5 to complete the table. **CORRECT ANSWER IS GIVEN BRAINLEST POINTS**
Answer:
x 10 4 6 1
y 5 2 3 0.5
Step-by-step explanation:
You have to start with a guess and see if it works. If it works, you're done. If it doesn't work, you need to make a difference guess.
I'll start by guessing that above the 0.5 is a 1.
If that is correct, then every x value is double the y value below it.
5 goes below the 10. 3 goes below the 6. Then you have 4 and 2 left.
That is every whole number from 1 to 5. It works.
x 10 4 6 1
y 5 2 3 0.5

Help!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
C. x = 6
Step-by-step explanation:
Answer: 6
Step-by-step explanation:
Solve for X
7 + 5 ( x - 3 ) = 22
7 + 5x - 15 = 22
-8 + 5x = 22
5x = 30
x = 6
Now check your work
7 + 5 ( 6 - 3 ) = 22
7 + 5 ( 3 ) = 22
7 + 15 = 22
22 = 22
A quadrilateral is reflected over the y-axis. Which of the following statements about the coordinates of the image are true?
ONeither the x-values nor the y-values change.
Both the x-values and y-values change.
o Only the y-values change.
O Only the x-values change.
The true statement about the coordinates of the image:
Only the x-values change.
The correct option is D.
What is a reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.
Given:
A quadrilateral is reflected over the y-axis.
The reflection rule:
Over the y-axis,
(x, y) → (-x, y)
Therefore, reflected coordinates: only the x-values change.

What is the value of x if
2x + 5 = 19 ? ASAP
Answer:
2x+5=19
2x=19-5
x=14/2
x=7
Answer:
[tex] \large \boxed{x = 7}[/tex]
Step-by-step explanation:
Goal
Solve for x-term.Given
Equation[tex]2x + 5 = 19[/tex]
Step 1
Isolate x by subtracting 5 both sides.[tex]2x + 5 - 5 = 19 - 5 \\ 2x + 0 = 14 \\ 2x = 14[/tex]
Step 2
Divide both sides by 2 to make only x-term as our subject.[tex] \frac{2}{2} x = \frac{14}{2} \\ \frac{1}{1} x = 7 \\ 1x = 7 \\ x = 7[/tex]
Step 3 (Optional)
If you are not sure that the answer is correct or not, we can check the answer by substituting x = 7 in the equation.[tex]2x + 5 = 19[/tex]
Substitute x = 7 in the equation.
[tex]2(7) + 5 = 19 \\ 14 + 5 = 19 \\ 19 = 19[/tex]
The equation is true for x = 7. Hence, the answer is x = 7.

Subtract 17x2y2z−14xyz from −18x2y2z+4xyz
Answer:
The difference is;
-35x^2yz^2 + 18xyz
Step-by-step explanation:
Here, we want to have a subtraction
we have this as;
(-18x^2y^2z + 4xyz) - (17x^2y^2z - 14xyz)
= -18x^2y^2z -17x^2y^2z + 4xyz + 14xyz

The cost of one CD and one DVD is $22. A DVD is $4 more expensive than a CD. Work out the individual prices of 1 CD and 1 DVD.
Answer:
ets Price of a DVD is fixed i.e. 15
and One CD price is 5 (Not fixed)
In First situation
2 DVDs and 1 CD cost = 35 as given
2 x 15 + 5 = 35
Lets one CD price is 7.5
In Second situation
2 x 15 + 2 x 7.5 = 45
Its mean CD price may be between 5 to 7.5
In asked scenario, Martin has 50
1 DVD and 3 CDs?
1 x 15 + 3 x 7.5 = 37.5
37.5 is lesser than 50
Step-by-step explanation:
Answer:
CD = $9
DVD = $13
Step-by-step explanation:
CD+DVD = 22
DVD = CD+4
substitute for DVD
CD +(CD+4) = 22
2CD+4 = 22
2CD = 18
CD = 9
DVD = 13

Answer:
-2 1/4, -1 1/4, 3/4, abs val 1 1/4, abs val -1 3/4, abs val - 2 1/4
Step-by-step explanation:
When you factor in the abs val, which look like a number stuck between two lines, you measure the distance of the number from zero which is ALWAYS POSITIVE. Therefore, change all the numbers inside abs val signs into positive numbers of the same value, for example abs val -1 3/4 would become 1 3/4 and arrange them from least to greatest.

The wheels on Darlene's car have on 11-inch radius. If the wheels are rotating at a rate of 378 rpm, find the linear speed in miles per hour in which she is traveling.
Answer:
The linear speed in which Darlene is traveling is 24.74 miles per hour.
Step-by-step explanation:
The wheel experiments rolling, which is a combination of translation and rotation. The point where linear speed happens is located at geometrical center of the wheel and instantaneous center of rotation is located at the point of contact between wheel and ground. The linear speed ([tex]v[/tex]), measured in inches per second, is defined by following expression:
[tex]v = R\cdot \omega[/tex] (1)
Where:
[tex]R[/tex] - Radius of the wheel, measured in inches.
[tex]\omega[/tex] - Angular speed, measured in radians per second.
If we know that [tex]R = 11\,in[/tex] and [tex]\omega \approx 39.584\,\frac{rad}{s}[/tex], then the linear speed, measured in miles per hour, in which Darlene is traveling is:
[tex]v = 11\,in\times \frac{1\,mi}{63360\,in} \times 39.584\,\frac{rad}{s}\times \frac{3600\,s}{h}[/tex]
[tex]v \approx 24.74\,\frac{mi}{h}[/tex]
The linear speed in which Darlene is traveling is 24.74 miles per hour.
A train traveled 63.75 miles at a rate of 85 miles per hour. Which equation can be used to find h, the number of hours it took the train to travel this distance? 85 - h = 63.75 63.75 = 85h 63.75 + h = 85 85 = 63.75h
Answer: 63.75 = 85h
Solving gives 0.75 hours.
Step-by-step explanation:
we now that speed = distance / time
therefore time will be Distance / speed
Given that distance = 63.75miles
Speed= 6=85miles per hour
Time(h) = 63.75miles/ 85.---- equation 1
But from the options given, the equation that can also be used to find number of hours is
63.75 = 85h
such that making h subject of formula still give us
h= 63.75/85 as in equation 1 above
solving gives that Time ( h) = 0.75 hours .

There are 18 marbles in Molly's bag. Two of the marbles are yellow. If Molly chooses one marble at random, find the theoretical probability that she will choose a yellow marble.
Answer:
1/9
Step-by-step explanation:
To find this probability, we simply divide the number of yellow marbles by the total number of marbles
From the question, there are a total of 18 marbles and 2 yellow ones
thus, the theoretical probability of selecting a yellow marble will be;
2/18 = 1/9
