What is the domain and range f(x)=|x+6| and how do I graph it

alexdok [17]

Answer:

domain: {0, infinity) range: (negative infinity, positive infinity)

graph it like a v, with the lines going on a slope of 1. Also, take it left 6 points.

Step-by-step explanation:

f(x)=(x+h) h is to move to the right and left. for example if h was positive 1 we go left 1. positive goes left and negative goes right. This is because it you set x+1=0 then x=-1.

Two solutions of the equation Ax+By = 1 are (2, -1) and (-3,-2). Find A and B.

kati45 [8]

Answer:

Substitute in the values of both given coordinates & form 2 equations:

$\left \{ {{A(2)+B(-1)=1} \atop {A(-3)+B(-2)=1}} \right. \\\\=\left \{ {{2A-B=1} \atop {-3A-2B=1}} \right.$

Find the value of B from the equation 2A - B = 1:

$2A-B=1\\-B=1-2A\\B=2A-1$

Substitute in the B-value to the other equation:

$-3A-2B=1\\-3A-2(2A-1)=1\\-3A-4A+2=1\\-7A=1-2\\-7A=-1\\A=\frac{-1}{-7} =\frac{1}{7}$

Find the B-value using the equation from before:

$B=2A-1=2(\frac{1}{7})-1=\frac{2}{7} -\frac{7}{7} =-\frac{5}{7}$

Therefore the equation Ax + By = 1 would equal:

$\frac{1}{7} x-\frac{5}{7} y=1$

The cost of a gallon of gas increased from $3.54 to $3.87 over the weekend. What is the percent increase for the cost of gas, ro

Dmitrij [34]

Answer:

Step-by-step explanation:

percent increase is calculated as

$\frac{increase}{original}$ × 100%

increase = $3.87 - $3.54 = $0.33 , then

% increase = $\frac{0.33}{3.54}$ × 100% ≈ 9% ( to the nearest whole percent )
