Y=7x+3 because slope intercept form is y=mx+b where x is the slope and b is the y intercept so when you plug in the slope of 7 and the y intercept of 3 you get the equation y=7x+3.
Answer:
He confused the height and the diameter
Step-by-step explanation:
the formula should have looked like this
V= 3.14 (2.5)^2 (24)
the reason why it is 2.5 and not 5 is because 5 is the diameter so divide 5 by 2 and you get 2.5
V= 3.14 (6.25) (24)
V= 3.14 (150)
V= 471
Answer:
centre = (3, 2) and radius = 4
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 = 16 ← is in standard form
with centre = (3, 2) and r = 
= 4
Answer:
<h2>1/2(x + 10) = x/2 + 5</h2>
Step-by-step explanation:
the sum of x and 10 = x + 10
one-half = 1/2
one-half the sum of x and 10 = 1/2(x + 10) = x/2 + 5
