Practice writing and solving quadratic equations. Anigment
The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where x represents
the smaller integer. Which equation can be factored and solved for the smaller integer?
O x²+x-72=0
O x2 + x + 72 = 0
x²+2x - 72=0
O x2 + 2x + 72 = 0

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
