Answer:
Using the equation y = abx , substitute both of your given points into that equation.
2 = ab2 and 4 = ab3 Solve each equation for a.
2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3
Cross multiply: 2b3 = 4b2 Divide both sides by b2
2b = 4 a = 2/4 = 1/2
b = 2
y = 1 (2)x
2
Step-by-step explanation:
Answer:
X=8, each side is=27
Step-by-step explanation:
Equilateral triangle, each side has the same lenght
5x-13=11x-61
61-13=11x-5x
48=6x
x=8
5(8)-13=27
Answer:
y = -9x + 12
Step-by-step explanation:
first find the slope
m= <u>3 - 12</u>
1 - 0
m = -9
y = mx + b
y = -9x + 12
(the 12 is the y intercept and is given in the question so there is no need to solve for it)
-13 is located the same distance away on the number line from -5 that 3 is.
f ( x ) = - ( x + 1)^2 + 4
