Answer:
y + 5 = 2(x - 3) (Answer A)
Step-by-step explanation:
Since the slope and a point on the curve are given, use the point-slope formula for the equation of a straight line:
y - k = m(x - h)
Here, m = 2, h = 3 and k = -5, so we have:
y + 5 = 2(x - 3) (Answer A)
let the no of sweets be 7x, 3x, and 1x
Colin gets 7x
Sara gets 3x
gordon gets 1x
7x = 1x+54 (given)
7x - 1x= 54
6x= 54
x=9
hece sara gets 3x= 3*9
=27
Step-by-step explanation:
Hey, there!!
you number is: 81/625
We know that,
81=9×9
and
625=25×25
and............................................................
9×9 means 9^2
and 25×25 means 25^2
so, the exponential form of the question is,
=
{we simply find exponential form by finding their fraction}

Answer:
23. 16x² + 4x + 0.25
24. 16x² - 4x + 0.25
Step-by-step explanation:
Given the functions f(x) = 4x + 0.5 and g(x) = 4x - 0.5, questions 23 and 24 are asking you to square the entire function. So, you will take the expression given in each function and square it:
(f(x))² = (4x + 0.5)(4x + 0.5) Using FOIL:
(4x*4x) + (4x*0.5) + (4x*0.5) + (0.5*0.5)
16x² + 2x + 2x + 0.25 = 16x² + 4x + 0.25
(g(x))² = (4x - 0.5)(4x - 0.5) Using FOIL:
(4x*4x) - (4x*0.5) - (4x*0.5) + (0.5*0.5)
16x² - 2x - 2x + 0.25 = 16x² - 4x + 0.25
