Answer:
3=-1/2(-2)+b
solve
3=1+b
2=b
b=2
now that we have the slope and y intercept of the equation construct your equation:
y=-1/2x+2
Neither of these answers are correct. I graphed them all and not a single one passed through (-2, 3)
Additionally, the slopes of B and D are inncorrect and lines A and C dont pass through the point (-2, 3) the only correct equation is y=-1/2x+2
I graphed it and it was valid
Maybe ask your teacher if there were any mistakes?
Step-by-step explanation:
Four is the answer I believe because if you go through it seems to be four
Answer:
So, area of quadrilateral ABCD = (½ × AC × BE) + (½ × AC × DF) We can calculate the area of different types of quadrilaterals by using the given formula. For the quadrilateral ABCD, if we use centimeter as the unit of measurement, the unit of measure for the area will be cm2 .
I hope it's helpful!
Answer: 66
<u>Step-by-step explanation:</u>
20 points per day is the rate, 100 points is the intial amount, and 1420 points is the total.
Use the formula: y = mx + b
- y is the total
- m is the rate
- b is the initial amount
1420 = 20x + 100 <em>plugged the values into the equation</em>
1320 = 20x <em>subtracted 100 from both sides</em>
66 = x <em>divided both sides by 20</em>
Step-by-step explanation:
Area = length × width
= 14 × 10
= 140cm^2
