Answer:x-5

Step-by-step explanation:

-6(2x+1)=54

Distribute:

-12x-6=54

Add 6 on both sides:

-12x-6+6=54+6

-12x=60

Divide 12 on both sides:

-12x/-12=60/-12

x=-5

Answer:

73.58

Step-by-step explanation: This is just a guess so I may be wrong. So when I put this into the calculator, it is showing a big number: 73.58485333 so what I did was round it to the nearest hundredths which is 73.58 so hope this helps somebody :)

Step-by-step explanation:

31-3x+9=-18

31-3x+9+18=0

58-3x=0

-3x=-58

x=-58/-3

x=19.33

so the answer is no solution

Answer:

really hard and strong but am interested

The two triangles are congruent through AA (angle-angle proportionality theorem) therefore all the sides are congruent to each other.

In this case:

2y = 5y - 7

2y - 5y = -7

-3y = -7

y = -7/-3

y = 7/3

Answer:

a

Step-by-step explanation:

The segment  RT is a perpendicular bisector and means Δ RSU is isosceles, then the 2 legs are congruent, that is

RS = RU , substitute values

8x = 6x + 5 ( subtract 6x from both sides )

2x = 5 ( divide both sides by 2 )

x = 2.5

Thus

RU = 6x + 5 = 6(2.5) + 5 = 15 + 5 = 20 → a

Answer:

5

Step-by-step explanation:

12-7=5

Answer:

5

Step-by-step explanation:

We know that x is equal to 7. That means we can replace x with this value. This makes our new expression:

12 - 7

12-7 is equal to 5, so this expression will equal 5 when x = 7.

Answer:

divide 195 by 2 , 5 times. Or 195 × 0.5^5

Answer: 4^9

Step-by-step explanation:

4^-7 is just 1/4^7 so this is equal to 4^2 divided by 1/4^7. Dividing by a fraction is the same thing as multiplying by its reciprocal (just flip the fraction). So this whole equation is equal to 4^2 multiplied by 4^7. And when you multiply two exponents with the same base, the exponents are just added. So, your answer should be 4^9. Hope this helps! :)

The solution to the inequality are the sets of points that lie where we have the shaded part

The coordinates (3,0) lie on the shaded part and thus will be a solution to the set of inequalities

Answer:

3.4

Step-by-step explanation:

Answer:

4(1 – x) + 2 x = -3( x + 1)

first do 4 time 1= 4

then do 4 times x =4x

now the equation should look like this

4-4x+2x=-3(x+1)

then do the other side of the equation

-3(x+1)

=-3x-3

Now collect the like terms:

-4x-2x

now the equation should look like this

4-2x=-3x-3

now add 3x add on both sides

4-2x+3x=-3

put the 4 on the other side

-2x+3x=-3-4

now again collect the like terms (-2x+3x=1 which is just x and -3-4 =-7)

x=-7

answer

x=-7

  [tex]x=-7[/tex]                    PLEASE MARK ME AS BRAINLIEST

Step-by-step explanation:

[tex]4(1-x)+2x=-3(x+1)[/tex]

Distribute 4 through the parentheses

[tex]4-4x+2x=-3(x+1)[/tex]

Distribute -3 through the parentheses

[tex]4-4x+2x=-3x-3[/tex]

Collect like terms

[tex]-4x+2x[/tex]

Collect like terms by calculating the sum or difference of their coefficient

[tex](-4+2)x[/tex]

Calculate the sum

[tex]-2x[/tex]

[tex]4-2x=-3x-3[/tex]

Move variable to the left hand side and change its sign

[tex]4-2x+3x=-3[/tex]

Why move an expression to the right?

We want to move an expression to the right to write the equation in a specific way.

The opposite needs to be added to both sides to preserve the relation between the sides. That is called the addition and subtraction property of equality/inequality

Step 1

Example

take the equation:

[tex]x+a=b[/tex]

We want the expression a to be on the right hand side of the equation.

Step 1

example(cont)

To move the expression to the right -hand side, use the addition property , and add -a to both sides of the equation:

[tex]x+a+(-a)=b+(-a)[/tex]

Simplify the left hand side and remove the parentheses on the right hand side:

[tex]x+a+(-a)=b+(-a)\\x=b-a[/tex]

Now the expression a is on the right hand side :

[tex]x=b-a[/tex]

Step 2:

Notice! when comparing  the beginning and the ending equation, it seems like we just moved the expression to the right hand side and changed its sign:

[tex]x+a=b\\x=b-a[/tex]

This is a shorter way to use the same property.

Now came back to the original equation

[tex]4-2x+3x=-3[/tex]

Move constant to to the right hand side and change its sign

[tex]-2x+3x=-3-4[/tex]

collect like terms

[tex]x=-3-4[/tex]

calculate the difference

[tex]x=-7[/tex]

Why move a constant to the right?

We want to move a constant to the right because the mathematicians agreed upon a convention that the constants in the equation and inequalities always need to be on the right-hand side.

The opposite needs to be added to both sides to preserve the relation between the sides. That is called the addition and subtraction property of equality/inequality.

Step 1

example

Take the equation:

[tex]x+3=5[/tex]

We want the constant 3to be on the right hand side of the equation.

Step 1

example (cont)

To move the constant to the right-hand side, use the addition property, and add -3 to both sides of the equation:

[tex]x+3+(-3)=5+(-3)[/tex]

Simplify the left-hand side and remove the parentheses on the right - hand side:

[tex]x+3+(-3)=5+(-3)\\x=5- 3[/tex]

Now , all the constants are on the right- hand side:

[tex]x=5-3[/tex]

Step 2

Notice! when comparing the beginning and the ending equation, it seems like we just moved the constants to the right hand side and change its sign:

[tex]x+3=5\\x=5-3[/tex]

This is a shorter way to use the same property.

Answer:

Both B and C, but I am not sure about just one answer.

Step-by-step explanation:

Answer:

y=2x

Step-by-step explanation:

y = kx is the format of the graph we are looking for (as told in the instructions) where k is the variable we are supposed to find (like y = x, y=2x, y=3x, etc)

Note that as x increases by 1, y increases by 2. We can see that by writing a table of the points of points that the line given intersects (picture below). We can see that by the values of the x-axis and the y-axis. Why does this happen? This is because y =2x for each value of x. We notice that in our table.

Therefore, the equation is y=2x. I hope this helps! If you still have questions, ask me in the comments!

Answer:

The equation of new line is: [tex]\mathbf{y=-\frac{1}{2}x-7}[/tex]

Step-by-step explanation:

We need to write an equation of the line that passes through the point (-2, -6) and is  parallel to the line x + 2y = 8

We need to find slope m and y-intercept b for the new line.

First we need to find slope m of the new line.

The given line x+2y=8 is parallel to new line.

When lines are parallel, there slope is same.

First writing equation in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept

[tex]x+2y=8\\2y=-x+8\\y=-\frac{1}{2}x+\frac{8}{2}\\ y=-\frac{1}{2}x+4[/tex]

Now comparing with [tex]y=mx+b[/tex] the slope is : [tex]m=-\frac{1}{2}[/tex]

Now finding y-intercept b

Using point (-2,-6) and slope [tex]m=-\frac{1}{2}[/tex] we can find y-intercept

[tex]y=mx+b\\-6=-\frac{1}{2}(-2)+b\\-6=1+b\\b=-6-1\\b=-7[/tex]

So, we get y-intercept b = -7

Now the equation of required line having slope [tex]m=-\frac{1}{2}[/tex] and y-intercept b = -7 is:

[tex]y=mx+b\\y=-\frac{1}{2}x-7[/tex]

So, the equation of new line is: [tex]\mathbf{y=-\frac{1}{2}x-7}[/tex]
