Hello:
equation is the line is : y = ax+b a is a slope
y = (-3/4)x+b
<span>passing through the point (−3;−3) : -3 =(-3/4)(-3)+b
y = (-3/4)x-(21/4)
</span>We draw the <span>Graph by two points : A(-3;-3) B(0;-21/4)</span>
Y-7=-2(x+1)
Y-7=-2x-2
Y=-2x+5
Answer:
The Slope is calculated Using the formula
The line passed through (5, 7) and (8, 8):
The slope is
The slope equals
Use the law of Cosines where
angle A = 14+22=36 degrees
side b = 6 times 7
side c = 6 times 19
So you have a triangle with 2 legs of 42 and 114 with angle A = 36 degrees between them.
The law of Cosines is then
a^2 = 42^2 + 114^2 - 2(42)(114)Cosine(36)
Solve and take the square root.
= 7012.85 taking the square root of it
= 83.74 km apart
Answer:
The total profit earned by the bakery today was of $495.75.
Step-by-step explanation:
Spending:
83 + 7 = 90 cakes made, each costing 6.25. So
Earnings:
83 cakes sold by $12.75, so:
Profit:
Earnings subtracted by spending, so:
The total profit earned by the bakery today was of $495.75.
