When x+2 = 1/5y is written in standard form, what is the value or B
Answer:
B=-1
Step-by-step explanation:
Standard form is Ax+By=C.
In this case, Ax is x, By is 1/5y, and C is +2.
To isolate the 2 (the C), subtract x from both sides of the equation:
x+2=1/5y
-x -x
2=-x+1/5y.
Now, the value of B, the x value, is -1.

Error Analysis: Find, describe & correct the error that a student has made while solving the equation: LaTeX: 4=-2\left(x-3\right)4 = − 2 ( x − 3 ) Step Number Equation 1 LaTeX: 4=-2\left(x-3\right)4 = − 2 ( x − 3 ) 2 LaTeX: 4=-2x-64 = − 2 x − 6 3 LaTeX: 4+6\:=\:-2x\:-\:6\:+\:64 + 6 = − 2 x − 6 + 6 4 LaTeX: 10\:=\:-2x10 = − 2 x 5 LaTeX: \frac{10}{-2}=-\frac{2x}{-2}10 − 2 = − 2 x − 2 6 LaTeX: -5=x
Given:
[tex]4=-2\left(x-3\right)[/tex]
To find:
The error that a student has made while solving the equation.
Solution:
We have,
[tex]4=-2\left(x-3\right)[/tex]
Using distributive property, we get
[tex]4=-2(x)-2(-3)[/tex]
[tex]4=-2x+6[/tex]
Subtract 6 from both sides.
[tex]4-6=-2x+6-6[/tex]
[tex]-2=-2x[/tex]
Divide both sides by -2.
[tex]1=x[/tex]
The value of x is 1.
In step 2, the distributive property is not used properly because when -2 is distributive with -3 then we get 6 instead of -6.
Therefore, the student has made error in step 2.

The point Q (5,3) is translated 2 units left. What are the coordinates of the resulting point Q
Answer:
(3,3)
Step-by-step explanation:
Since it's to the left, and not up or down at all, the y-value does not change. The x-value, however, is affected. Since it's to the left, it is decreasing in value by 2 points. If it were to the right, it would increase in value to (7,3), since it'd be going further away from (0,0).
Answer:
Q = (3,3)
Step-by-step explanation:
Moving the point left moves the x value down 2.
5-2=3
Therefore, Q = (3,3)

Using Oliver’s table, how can you find the unit rate?
Answer:
Is there a table I can see if I'll be able to help
Answer:
Oliver’s table indicates that for every increase of 2 strides, the distance he travels increases by 7 feet. So, the change in distance divided by the change in stride gives the unit rate.

that equals to 3
then you do 1 by 2 (aka 1*2)
then it is 3-2 which equals to 1
Find the answer for x.
Answer:
x=25
Step-by-step explanation:
since this is a triangle you would add up all the measure of this and set it equal to 180. 90 is the side with the box. so it would be 2x+15+x+90=180 then solve for x and you would get your answer.

Solve for x: −2(x + 3) = −2x − 6 NEED HELP PLZ:(
A: 0
B: 3 C:All real numbers
D:No solution
Answer:
The answer is C:All real solutions
Step-by-step explanation:
here are the steps in case u need them :)
Step 1: Simplify both sides of the equation.
−2(x+3)=−2x−6
(−2)(x)+(−2)(3)=−2x+−6(Distribute)
−2x+−6=−2x+−6
−2x−6=−2x−6
Step 2: Add 2x to both sides.
−2x−6+2x=−2x−6+2x
−6=−6
Step 3: Add 6 to both sides.
−6+6=−6+6
0=0
Answer:
C: All real numbers.
Step-by-step explanation:
-2 ( x + 3 ) = -2x -6
-2 times x, -2 times 3
-2x -6 = -2x -6
Add 6
-2x -6 +6 = -2x -6 +6
-2x = -2x
same as....
0 = 0

what property is 4x + 8 = 28
Answer:
x=5
Step-by-step explanation:
4x + 8 = 28,
it's rather straight forward,
you would subtract 8 from the left side,
doing the same on the right.
now you have
4x = 20
x= 20/4
x=5
hope this helps.

Factor the following trinomial completely, or state that the trinomial is prime.
3x^2+10xy + 8y^2
Answer:
(3x + 4y)(x + 2y)
Step-by-step explanation:
3x^2+ 10xy + 8y^2
All signs are positive, so we'll only look at positive factors of 3 and 8.
3 factors into 3 and 1.
8 factors into 4 and 2, and it also factors into 8 and 1.
I like to try closer factors in value, so I'll start with 4 and 2 for 8.
Try:
(3x + 2y)(x + 4y) = 3x^2 + 12xy + 2xy + 8y^2 = 3x^2 + 14xy + 8y^2
The middle term does not work. Switch 2y and 4y and try again.
Try:
(3x + 4y)(x + 2y) = 3x^2 + 6xy + 4xy + 8y^2 = 3x^2 + 10xy + 8y^2
It works.
Answer: (3x + 4y)(x + 2y)
