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.
Factor the following trinomial completely, or state that the trinomial is prime.
3x^2+10xy + 8y^2
Answers
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)
What is the value of r for 19 and 20?
Answers
Answer:
19.) r = -4 20.) r = 1
Step-by-step explanation:
19.) Because we know the slope and have some points, we can use point-slope form to find the equation.
Point-slope form is:
y - y1 = m(x - x1)
Substitute the numbers into the equation:
y - 3 = 7/6(x - 1)
y - 3 = 7/6x -7/6
y = 7/6x + 11/6
Now that we know the equation, we can put in the x value to find the y (In this case, y = r):
r = 7/6(-5) + 11/6
r = -35/6 + 11/6
r = -4
20.) Because the slope is undefined, that means on the graph, the line will appear straight and vertical. This means the equation will be something like x = a number.
We have the point (1,4). Since we know that the x value will never change, we know that r will have to equal 1 as well.
r = 1

is it possible for two triangles to have the same angle measures but not be congruent?explain.
Answers
Answer:
Yes
Step-by-step explanation:
One triangle can be bigger then another and still have the same angle measure.
Yes, it is possible for two triangles to have the same angle measures but not be congruent.
What is congruency?If two triangles are congruent, this means they are the same shape and the same size.
One triangle can be bigger than another and still have the same angle measure. For example, if there are two equilateral triangles all the angles are 60 degrees.
But one triangle is having a side of 10 units and the other triangle is having a side of 20 units means the second triangle is bigger than the first but the angle for both the triangles is 60 degrees.
Therefore, it is possible for two triangles to have the same angle measures but not be congruent.

Nolan gave out a survey to some students in his school about their favorite color. Students could choose between red and purple. 238 of those surveyed said their favorite color was red. 66% of the students surveyed said their favorite color was purple. How many students were surveyed in total?
Answers
Answer:
700
Step-by-step explanation:
100%-66%=34%
34% equals the 238 that is red
238÷34%=7 people per percentage
7×66%= 462 students that chose purple
462+238=700 which should be the total amount of people surveyed.
When x+2 = 1/5y is written in standard form, what is the value or B
Answers
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.

Step-by-step explanation:
It's literally the same equation written in reverse, which according to the commutative property, can be done.
Answer: A
Step-by-step explanation:
For this problem, we know that A is the correct answer. A is the same as the given expression because it is the same, but the order is switched. When you multiply both of them, you would get the same answer.
We can eliminate B because [tex]\frac{2}{5}[/tex] should be positive, not negative.
We can eliminate C because the fraction should be [tex]\frac{2}{5}[/tex], not [tex]\frac{5}{2}[/tex].
We can eliminate D because (-1×-7) given you 7, not -7.
Therefore, A is the right answer.
