Write a system of linear equations for the graph below.
Answer:
y=-1/2x+2
y=-3x-3
Step-by-step explanation:
Slope is rise/run, so finding slope is looking at y/x of the lines in between two points.
Then finding the y-intercept you look along the y-axis where the line passes through and what the value there is (look out for positive or negative!).

Note: there is typo- 549 should read $49
Discount is:
$70 - $49 = $21Discount % is:
21/70*100% = 30%Applying same discount to pair of shoes for $110:
$110 - 30% =$110*(100 - 30)/100 = $110*0.7 =$77Correct option is B

A company’s stock begins the week with a price of $43.85 per share.
The price changes by $2.70 each day for 2 days. Then the price changes by −$1.10 each day for 2 days. On the last day, the price changes by −$4.45.
What is the price per share of the company’s stock after those five days?
Answer:
$42.60 per share
Step-by-step explanation:
1. 2(2.7) + 2(-1.1) + (-4.45) = -1.25
2. 43.85 + -1.25 = 42.6

A monthly budget is shown. Which equation can be used to determine y, the minimum amount of money a family must earn to meet the requirements of this budget for one year?
Answer:
$3600 * 12
Step-by-step explanation:
To get the minimum amount of money the family must earn to meet the requirements of their budgets for one year, first you have to get their total budget for a month and then multiply it by the number of months in a year.
The monthly budget = Rent + food + child care + transportation + utilities + insurance + savings + taxes
Monthly budget = $870 + $550 + $375 + $480 + $400 + $235 + $400 + $290 = $3600
Minimum requirements for one year = $3600 * 12 months

Write the equation in standard form of the line that passes through (-1,-4) parallel to 9x -y = 4
Answer:
9x-y=-5
Step-by-step explanation:
First, put this equation into slope intercept form (makes it easier)
9x-y=4
subtract 9x from both sides
-y=-9x+4
multiply by -1 on both sides
y=9x-4
Parallel lines have the same slopes, so the second line is y=9x+b (b is a placeholder for the y intercept)
now, find the y intercept
since the line has to go through (-1,-4), plug it into the equation
-4=9(-1)+b
-4=-9+b
5=b
so now the line would be y=9x+5... in slope intercept form. The question asks for the answer to be in standard form.
5 from both sides
y-5=9x
subtract y from both sides
-5=-y+9x
or
9x-y=-5

Write an equation of the parabola with vertex (0, 0) and directrix x=2.
Answer:
y² = -8xStep-by-step explanation:
directrix x=2 and vertex (0, 0) means focus: (-2, 0)
also means the distance from the origin to the focus: a=2
y² = -4ax
y² = -4×2x
y² = -8x
