In a class of 24 kids, for every 1 boy there are 4 girls
Answer:
2
Step-by-step explanation:
Basically you don't need to find x to know the scale factor ,
but I did.So you see that multiple 3 by 2 you will get 6
(MN) and the same will happen with 5.5 and NO (which is 11 btw).
so you can write 2:1
Answer:
The range is y ≥ -1
Step-by-step explanation:
∵ f(x) = (x - 4)(x - 2)
∴ f(x) = x² - 2x - 4x + 8
∴ f(x) = x² - 6x + 8 ⇒ quadratic function (ax² + bx + c) represented by
parabola graphically
∵ a = 1 , b = -6 , c = 8
∴ x-coordinate of its vertex = -b/2a = -(-6)/2×1 = 3
∴ f(3) = (3)² - 6(3) + 8 = -1
∵ a is positive ⇒ the curve has minimum point and it's open upward
∴ the minimum point is (3 , -1)
∴ The range is y ≥ -1 ⇒ because the minimum value is -1
There is one solution.. for a pair of lines if the lines are perpendicular (these are) they only touch once
The first one A) :)))))))
