Answer:
x=3.5
Step-by-step explanation:
if y = y
20x+115=10x+150
-10x -10x
10x+115=150
-115 -115
10x=35
x=3.5

Answer: Yes, the answers in the blanks are correct.
Step-by-step explanation: The easiest way to answer this question is to plot the points onto a graph. The point (0,10) is right on the y-axis, so that would be the y-intercept. The best way to find the slope is the rise over run method. The slope 2/5 is correct because it "rises" by 2 units and "runs" by 5 units.
Answer:
FD = 8
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
=
( cross- multiply )
2(2x + 2) = 3(x + 3) ← distribute parenthesis on both sides
4x + 4 = 3x + 9 ( subtract 3x from both sides )
x + 4 = 9 ( subtract 4 from both sides )
x = 5
Thus
FD = x + 3 = 5 + 3 = 8
Answer:
y=2
because 4x2 =8 then 8-4 equals to 4 which is what your trying to get
