Answer:
Step-by-step explanation:
Given the coordinate points (6, -3) and (7, -10), we are to find the equation of a line passing through this two points;
The standard equation of a line is y = mx+c
m is the slope
c is the intercept
Get the slope;
m = Δy/Δx = y2-y1/x2-x1
m = -10-(-3)/7-6
m = -10+3/1
m = -7
Get the intercept;
Substitute the point (6, -3) and m = -7 into the expression y = mx+c
-3 = -7(6)+c
-3 = -42 + c
c = -3 + 42
c = 39
Get the required equation by substituting m = -7 and c= 39 into the equation y = mx+c
y = -7x + 39
Hence the required equation is y = -7x + 39
Answer:
L=10cm , W=30cm
Step-by-step explanation:
First use the given that W=10+2*L
Use P=2W+2L=80, substitute W in the perimeter formula
2(10+2L)+2L=80 and solve for L,
20+4L+2L=80 isolate variable L and combine like terms,
6L=80-20,
L=10, so W=10+2*10=10+20=30

25+10 is the answer
In the Commutative law of addition, it says that a+b and b+a are the same which makes ab and ba equal to one another.
To prove just add 10+25 and 25+10to show that both results in 35 (aka the same answer)
If you would like to find the function that gives the profit Betty makes by selling glasses of lemonade, you can find this using the following steps:
p ... profit
g ... glasses of lemonade
p = g * $1 - $50
The correct result would be <span>p = g * $1 - $50.</span>
