use a system of equations to solve the word problem. a rectangular table has a perimeter of 18 feet. its length is 5 feet greater than its width. find the dimensions.
a. l = 8 and w = 3
b. l = 7 and w = 2
c. l = 2 and w = 7
d. l = 3 and w = 8
x-intercepts are (-3,0) and (-4,0).
y-intercept is (0,12).
x-intercept is a point where the value of y is zero.
y-intercept is a point where the value of x is zero.
given equation is :
put x=0 in given equation to find y-intercept.
hence, y-intercept is (0,12).
put y=0 in given equation to find x-intercept.
split the middle term of above equation to make the equation into two groups such that the sum of two numbers should be 7 and their product be 12.
making two groups and taking common out:
take (x+3) common,
x+3=0 or x+4=0
x=-3 or x=-4
hence, x-intercepts are (-3,0) and (-4,0).
they are the same triange o were the letters are on the 1 triangle the right numbers are on the other triangle bud. hope this ! : )
