Answer:
x=1, y=19. (1, 19).
Step-by-step explanation:
-9x+y=10
10x-y=-9
--------------
x=1
10(1)-y=-9
10-y=-9
y=10-(-9)=10+9=19
Answer: I was kind of confused but here: x=3, y=21. if i am wrong try to be more elaborate and i will try to help

Answer:
1. x= 5, x=1
2. x= -4, x=2
3. x= -6, x=7
4. x= -7, x=5
5. x= -9, x=0
Step-by-step explanation:
You do the X factoring-
1.
A B C
x²+6x+5
(A)(C) and B
(1)(5)=5 6
Then figure out what two numbers multiply to get 5
but also add to 6. In this case, it would be 5 and 1
5x1= 5 and 5+1= 6
so it is:
x= 5, x= 1
Hope this helps!

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.

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

Find variables for this alegraic expression: -3x-2x+16+5-8+x
Answer:
2x+13
Step-by-step explanation:
collect like terms:
(3x−2x+x)+(16+5−8)
Answer:
-4x+13
Step-by-step explanation:
Let's simplify step-by-step.
−3x−2x+16+5−8+x
=−3x+−2x+16+5+−8+x
Combine Like Terms:
=−3x+−2x+16+5+−8+x
=(−3x+−2x+x)+(16+5+−8)
=−4x+13
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.
Work out
cube root of 1331 : reciprocal of 0.2
Give your answer in the form n: 1
Answer:
11:5
Step-by-step explanation:
The computation is shown below:
Given that
Cube root of 1331: reciprocal of 0.2
11: 5
So here n denotes the 11
And, 1 denotes the 5
Therefore the answer is 11:5
Hence, the same would be considered and relevant too

Josephine wrote the numbers 1-100 and placed them in a bag. If she selects a number without looking, what is the probability that the number is greater than 78? Input your answer as a decimal or fraction.
Answer:
0.22
Step-by-step explanation:
The numbers that would be greater than 78 would include numbers after 78. that is 79, 80 ... 100
The total numbers greater than 78 is 22.
And there are 100 numbers in the bag . the probability of picking a number greater than 78 is 22/100 = 0.22

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
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

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
= -35x^2yz^2 + 18xyz
