I need help I’m struggling

Answers

Answer 1

All you need for a point to be left unchanged is it being on the line of reflection. (Generally speaking)

The first one is wrong cause you can have a line of reflection anywhere. If the line is horizontal ( x axis) then the slope would be zero. Whereas a line on y axis would be an undefined slope. There are also diagonal lines of reflections which have slopes

I am pretty sure the second one would be correct because, as previously stated, all the line needs to stay in the same place is it being on the line of reflection.

Again, lines of reflection do not have a set slope, a diagonal line of reflection going like / on the chart through the axis could have a slope of one, but it is not needed for the point to remain in the same place

The point does not necessarily need to be on the origin, it can be anywhere on the line of reflection, and if the line of reflection does not pass through the origin, a point on the origin would be moved in a reflection.

I hope this makes sense and helps you out a bit... have a good day

234% as a simplifed fraction

Answers

Answer:

So, /(100÷2) = 117/50 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 234/100 is also equal to 2 17/50 when expressed as a mixed number.

Step-by-step explanation:

Solve 4b +8= 6b - 4 b= ?

Answers

Answer:

B = 6

Step-by-step explanation:

1. 4b + 8 = 6b - 4

2. Add 4 to both sides: 4b + 12 = 6b

3. Subtract 4b from both sides: 12 = 2b

4. Divide 12 by 2: b = 6

Brainliest Please.

Answer:

b = 6.

Step-by-step explanation:

4b + 8 = 6b - 4

4b - 6b = -4 - 8

-2b = -12

b = -12/-2

b = 6.

Answer:

D. x = 10, m<TRS = 60

Step-by-step explanation:

1. Approach

To solve this problem, one will set up an equation to model the problem. The problem gives that the sum of two angles (m<QRT and m<TRS) equals the third angle (m<QRS). Additionally, the measure of one of the angles is given (m<QRS = 122), and the expression for the values of the other two angles are given, (m<QRT = 7x - 8), (m<TRS = 6x). One can form an equation, and solve it to find the unknown. Finally, one can then substitute the values of the unknown, into the expression to find the measure of the angle.

2. Solve for (x)

One can set up an equation based on the given information, then solve the equation.

m<QRT + m<TRS = m<QRS

Substitute,

(7x - 8) + (6x) = 122

Simplify

7x - 8 + 6x = 122

13x - 8 = 122

Inverse operations

13x - 8 = 122

+8 +8

13x = 130

/13 /13

x = 10

3. Find (m<TRS)

Now that one has the value of (x), one can substitute the value into the given expression for the (m<TRS), and solve to find the value.

m<TRS = 6x

x = 10

m<TRS = 6(10)

m<TRS = 60

What are the solutions of the equation
-12x+26=-(1/5)-x+2+3

Answers

Answer:

Step-by-step explanation:

Expand -(1/5)-x+2+3

-(1/5)-x+2+3

Remove the parenthesis;

=1/5-x+2+3

Add the numbers; 2+3=5

=-x+5-1/5

Convert element to fraction;

=5*5-1/5

Since the denominators are equal combine the fractions;

5*5/5-1/5

5*5-1=24

Multiply the numbers;5*5=25

=25-1

Subtract the numbers:25-1=24

=24

=-x+24/5

-12x+26=-x+24/5

Subtract 26 from both sides;

-12x+26-26=-x+24/5-26

Simplify;

-12x+26-26

Add similar elements; 26-26=0

=-12x

Simplify;-x+24/5-26

Convert element to fraction;

- 26/*5/5+24/5

Since the denominators are equal , combine the fractions;

-26*5+24

Multiply the numbers; 25*5=130

=-130+24

Add/subtract the number;-130+24=-106

=-106

=-106/5

Apply the fraction rule;

=-x-106/5

-12x=-x-106/5

Add x to both sides;

-12x+x=-x-106/5+x

Simplify;

-11x+=-106/5

Divide both sides by -11

-11x/-11=-106/5/-11

Simplify ;-11x/-11

Divide ;11/11

simplify;-106/5/-11

Apply fraction rule; 106/5/11

106/5*11

Multiply the numbers;5*11=55

=106/55

x=106/55
