Answer:
GH=5
HI=5
IJ=5
JK=9
Step-by-step explanation:
GK=24
HJ=10
GH=HI=IJ.
Let GH, HI, IJ be x
therefore,
HI+IJ=10
=>x+x=10
=>2x=10
=>x=10/2
=>x=5
HI=IJ=GH=5
GH+HI+IJ+JK=GK
=>5+5+5+JK=24
=>15+JK=24
=>JK=24-15
JK=9
Slope Intercept Form: y = mx + b
(x, y) --> point on the line
m --> slope
b --> y-intercept
Point Slope Form: (y - y1) = m (x - x1)
(x1, y1) --> point on the line
m --> slope
Now that we know that information, we can substitute in what we know.
Slope Intercept Form: y = -1/2x + 3
Any equation will have to simplify to the equation above if it is an equation of the line.
A. 2y = 6 + x
y = 6/2 + x/2
y = 3 + 1/2x
<em>Not an equation.
</em>
B. x + 2y = 6
2y = 6 - x
y = 6/2 - x/2
y = 3 - 1/2x
y = -1/2x + 3
<em>Equation.
</em>
C. y = -1/2x + 3
<em>Equation.
</em>
D. (y - 2) = -1/2 (x - 2)
y - 2 = -1/2x + 1
y = -1/2x + 3
<em>Equation.
</em>
B, C, and D are all equations that represent the line.
Answer:
9/35
Step-by-step explanation:
There are a total of 15 bulbs to choose from randomly. First a new bulb is chosen. Chance is 9/15 because 9 out of 15 are new.
Then there are only 14 bulbs left. Then a used bulb is chosen. Chance is 6/14 since 6 out of remaining 14 are used.
Total chance for this to happen is 9/15 * 6/14 = 54/210 = 9/35.
Answer:
x=3
Step-by-step explanation:
both of the two sides equal the same so it would be 3x=9x-18
solve you get x=3
