(3.75, 5.5)
(Work is attached )
When using substitution , you substitute with a variable that is already by itself. In this case, the variable “y” is already by itself and equal to x+ 1.75 . you substitute that for the the y in the other equation and solve for the other variable which is “x”. After you solve for x , to find your y value, you have to substitute the x value in for either equation.
Answer:
a= 81m^2
Step-by-step explanation:
we know the top triangle: the base is 9
a = 1/2(bh)
a = 1/2 (9 x 8)
a = 1/2 (72)
a = 36
the parallelogram at the bottom has base 9 and height 5
a = bh
a = 9 x 5
a = 45
add them together 36 + 45 = 81
Answer:
B. It will move but wont change shape or size.
Step-by-step explanation:
Step-by-step explanation:
x =7y ----(1)
xy=252 ----(2)
(1) into (2):
(7y)(y) = 252

7y=15.874....
y=2.27
y value into (1)
x= 7(2.268)
x=15.87
the two numbers are 15.87 and 2.27 (Ans)
9 - 22 is -13 then add 12 yards equals -1 so they just lost one years from where they started so the answer is -1
