Answer:
Step-by-step explanation:
the funny lines in the corners of the triangle mean that the angles are the same. Maybe you knew that?
The supplementary angle at the top right is just
180- 17x -23
now you have expressions for each of the 3 angles of the triangle which all add up to 180°
180= 7x + 2 + 7x +2 + 180- (17x -23)
180 = 14x +4 + 180 - 17x +23
180 = -3x +207
3x = 27
x = 9
The formula for exponential growth is: Total = Starting value(1 + rate)^time
2018 to 2025 is 7 years:
Total = 50,000(1+0.037)^7
Total = 50,000(1.037)^7
Total = 64,479
Answer:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2
2(6a - 5) + 2(a + 1) =
= 12a - 10 + 2a + 2 =
= 12a + 2a - 10 + 2 = <u>1</u><u>4</u><u>a</u><u> </u><u>-</u><u> </u><u>8</u>
Since it is a line function, you just need two points to graph it.
So if you take x=0, you get y=0; which is the origin.
And when x=1, y=4.
You should get something like the attached picture.
