Solve 3x + y = 1 for y*

Answer:

Step-by-step explanation:

Using the distance formula: distance = [tex]\sqrt{(x_{2} -x_{1})^{2}+(y_{2} -y_{1})^{2} }[/tex]

sub it in,

10 = [tex]\sqrt{(10 -2)^{2}+(y-(-3)^{2}}[/tex]

10 = [tex]\sqrt{(8)^{2} +(y+3)^{2}}[/tex]

10 = [tex]\sqrt{64+y^{2} +9+6y}[/tex]

10 = [tex]\sqrt{73+y^{2} +6y}[/tex]

square both sides:

100 = 73 + [tex]y^{2}[/tex] + 6y

[tex]y^{2}[/tex] + 6y = 27

y( y + 6) = 27

y = 27 OR THE OTHER SOLUTION IS y + 6 = 27

y = 21

Answer:

1

Step-by-step explanation:

The equation of the following line looks like this:

[tex]y=x[/tex]

In this type of line, every single y value corresponds to the given x value. The slope of this line is considered to be positive one, as you can multiply x by one and still get the same number (Identity property)

A constant of proportionality originates from this type of equation:

[tex]y=kx[/tex]

K is the constant, and the number multiplied by x. It can also be recognized as the slope (m)

Answer:

I think 50 i may be wrong though

Step-by-step explanation:

Answer:  3t - 6

Reasoning:

We multiply the outer term 3 by each term inside, which is t and -2

3 times t = 3*t = 3t

3 times -2 = 3*(-2) = -6

Add up those results to get 3t+(-6) = 3t-6

Therefore, 3(t-2) = 3t-6

This is an example of the distribution property.

Answer:

18

Step-by-step explanation:

3(t-2)

3x2=6

(t-6)

3(6)

3x6= 18

Answer:

Historically, surnames evolved as a way to sort people into groups - by occupation, place of origin, clan affiliation, patronage, parentage, adoption, and even physical characteristics (like red hair). Many of the modern surnames in the dictionary can be traced back to Britain and Ireland.

Answer: -4c+12

all real numbers

Step-by-step explanation:

6) 28-(3c+4) =2 (c+6)+c

When there is a - in front of an expression in parentheses , change the sign of each term of the expression.

28-3c-4=2(c+6)+c

Distribute 2 through the parentheses

28-3c-4=2c+12+c

Now we do the same thing only different way

2(c+6)

Multiply each term in the parentheses by 2

2c+2×6

Multiply the numbers

2c+12

_____________

28-3c-4=2c+12+c

subtract the numbers

24-3c=2c+12+c

Collect like terms

24-3c=3c+12

It's the same thing only different way ok

2c+c

If a term doesn't have a coefficient , it is considered that the coefficient is 1.

2c+1c

Collect like terms by adding their coefficients

(2+1)c

Add the numbers

3c

________

24-3c=3c+12

Move variable to the left hand side and change its sign

24-3c-3c=12

Move constant to the right  by adding its opposite to both sides

-3c-3c+24-24=12-24

eliminate the opposites

-3c-3c=12-24

Collect like terms

-6c=12-24

Calculate the difference

-6c=-12

so the same thing only different way ok

12-24

Keep the sign of the number with the larger absolute value and subtract the smaller absolute value from the larger.

-(24-12)

Subtract the numbers

-12

__________

-6c=-12

divide both sides of the equation by -6

-6c÷(-6)=-12÷(-6)

Any expression divided by itself equals 1

c=-12÷(-6)

Dividing two negatives equals a positive

(-)÷(-)=(+)

c=12÷6

Calculate the quotient

c=2

Step-by-step explanation:

We know she makes $72.85 at selling cookies if she sales 17 cupcakes for $3.25 she'll make $55.25 but were trying to find how many she sales with $1.60 so $72.85 divided by 1.60 is 45.5 and if not then it's 46. rounded.
