Answer:
Blue paint: 1, 2, 2.8, 10
Red paint: 2.5, 5, 7, 25
Step-by-step explanation:
constant of proportionality: 2.5
2.5x = y
Answer:
9
Step-by-step explanation:
3
3 x
=
14 42
3
(2,3)(4,4)
slope(m) = (4-3) / (4-2) = 1/2
y = mx + b
slope(m) = 1/2
(4,4)...x = 4 and y = 4
now we sub
4 = 1/2(4) + b
4 = 2 + b
4 - 2 = b
2 = b
equation is : y = 1/2x + 2
Answer:
r = 2 units
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 3)² + (y + 2)² = 4 ← is in standard form
with r² = 4 ⇒ r = 
= 2
