Answer:
Step-by-step explanation:
If the price is linear, then the slope between each pair of points must be the same.
m = Δy/Δx
m = (150 - 70) / (5 - 1) = 20
m = (450 - 150) / (20 - 5) = 20
m = (1050 - 450) / (50 - 20) = 20
So the equation is indeed linear. It has a slope of 20 and y-intercept of 50.
p = 20n + 50
Answer:
a
Step-by-step explanation:
1 chair = X
8 chairs = 8X
1 table = Y
8X - Y is the more amount you paid for chairs
Third option! Hope this helps
X= 20 & Y= 70 in right-angled triangle .
What is right angle triangle?
- A right-angled triangle is a particular kind of triangle in which one of the angles is 90 degrees.
- The combined angles of the other two are 90 degrees. Perpendicular and the triangle's base make up the sides that the right angle is formed from.
- The longest of the three sides, known as the hypotenuse, is the third side.
2X + 140 = 180
2X = 40°
X = 20°
X + Y = 90°
Y = 70°
