Need someone to work this problem showing the steps

Well first you would subtract 9 from both sides to isolate your variable
so it would look like
1/4y =-81/2
now you divide 1/4 from both sides
so you're left with
y = -34

What’s the vertical and horizontal line?

coldgirl [10]

Answer:

Part 1) Vertical line : $x=1$

Part 2) Horizontal line : $y=-4$

Step-by-step explanation:

Part 1) Write the equation for the vertical line passing through the point (1,-4)

we know that

The equation of a vertical line (parallel to the y-axis) is equal to the x-coordinate of the point that passes through it

The x-coordinate is 1

therefore

The equation of the line is

$x=1$

Part 2) Write the equation for the horizontal line passing through the point (1,-4)

we know that

The equation of a horizontal line (parallel to the x-axis) is equal to the y-coordinate of the point that passes through it

The y-coordinate is -4

therefore

The equation of the line is

$y=-4$

Show how you solve the following two equations:<br> x – 15 = 32<br> x – 7.2 = 23.1

Lapatulllka [165]

Х - 15 = 32
х = 32 + 15
x = 47 (answer)
-----------------------
47 - 15 = 32
32 = 32

х - 7.2 = 23,1
х = 23,1 + 7.2
х = 30,3 (answer)
---------------------------
30,3 - 7,2 = 23,1
23,1 = 23,1

Find P(not a 3). X 1 2 3 4P(X) 0.30 0.40 0.15 0.15

zhannawk [14.2K]

From the table,
P(selecting a 3) = 0.15

which means that,
P(not a 3) = 1 - P(selecting a 3)
P(not a 3) = 1 - 0.15
P(not a 3) = 0.85

Answer is 0.85
