I'm not sure what I am supposed to do.

What is -6x+4=-50 and 5x+6=-44 also -3(7+6x)=-201 please solve these equations and show work

grandymaker [24]

Remember you can do anyting to an equation as long as ou do it to both sides

-6x+4=-50
minus 4 both sides
-6x=-54
divide both sides by -6
x=9

5x+6=-44
minus 6 both sides
5x=-50
divide both sides by 5
x=-10

-3(7+6x)=-201
normally you would distribute (that works) but it's easier to divide both sides by -3
7+6x=67
minus 7 both sides
6x=60
divide by 6 both sides
x=10

My house is 20 miles from yours, but on the map it is only 4 mm away. What is the scale of the map? O A Imm = 5 mi B. I mm = 20

dlinn [17]

$\huge \bf༆ Answer ༄$

Let's use Unitary method to solve the question ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:4 \: mm \rightarrow20 \: miles$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:1 \: mm \rightarrow(20 \div 4) \: miles$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:1 \: mm \rightarrow5 \: miles$

Therefore, 1 mm corresponds to 5 mile according to the map.

so, correct choice is ~

$\overbrace{ \underbrace{\underline{ \boxed{ \sf A }}}}$

What is the equation of exponential regression equation? Round all numbers you your answer to three decimal places

ExtremeBDS [4]

Given:

The given values are:

$a=0.2094539899$

$b=2.507467975$

$r^2=0.9435996398$

$r=0.9713905701$

To find:

The exponential regression equation for the given values (Rounded to three decimal places).

Solution:

The general form of exponential regression equation is:

$y=a\cdot b^x$ ...(i)

Where, a is the initial value and b is the growth/decay factor.

We have,

$a=0.2094539899$

$b=2.507467975$

Round these numbers to three decimal places.

$a\approx 0.209$

$b\approx 2.507$

Substitute $a=0.209, b=2.507$ in (i) to find the exponential regression equation.

$\hat{y}=0.209\cdot 2.507^x$

Therefore, the correct option is C.
