Answer:

y = 1/2x - 2

Step-by-step explanation:

Slope intercept form:

y = mx + b

x - 2y = 4

-2y = -x + 4

2y = x - 4

y = 1/2x - 2

Answer: y=(1/2)x + 2

Slope intercept form: y = mx + b
y= answer, y-value
m=slope
x= independent variable, x-value
b= y-intercept (0,b)

x-2y=4
1. Isolate 2y by adding x to both sides of the equation: 2y = 4+x
2. Isolate y by dividing 2 to both sides of the equation: y = 2+(1/2)x
3. Rearrange in slope intercept form.
y=(1/2)x + 2

Consider the sequence following a minus 8 pattern: 9, 1, −7, −15, ….

photoshop1234 [79]

Answer: -287

Step-by-step explanation:

The given pattern: 9, 1, -7, -15, ….

We observe that ,

First term : a=9

Common difference between the terms= 1-9=-8

For Arithmetic sequence , the formula to find the nth term is given by :-

$a_n=a+(n-1)d$

Then, 38th term will be :-

$a_{38}=9+(-8)(38-1)\\\\=9-8(37)=9-296=-287$

Hence, the 38th term of the sequence.= -287

Snezhnost [94]

Plug in x=1 and y=2 into the inequality:-
2x + 9y = 2 + 18 = 20

20 is not < 20
so it is not a solution

If there 10% of a 60ml bottle is filled with antifreeze, how much antifreeze (ml) was in the bottle? If 50% of a 20ml bottle is

miss Akunina [59]

Answer:

Part A: 6ml of antifreeze

Part B: 10ml of antifreeze

Step-by-step explanation:

10% of 60ml is 6ml

60/10 = 6

1/10 of 60 equals 6ml.

50% of 20ml is 10ml.

20/2 = 10

1/2 of 20 equals 10ml.

the radius of s cylinder is 3x-2cm the height of the cylinder is x+3 cm what is the surface area of the cylinder

Mashcka [7]

If you picture a cylinder rolled out flat. there would be two circles for top and bottom and then a rectangle for the side. The rectangle would have width equal to height and length equal to circumference.

So then the areas of the pieces are added together to get total surface area.

= 2pi(3x-2)^2 + 2pi(3x-2)(x+3)

and you can simplify this is you want by multiplying through and combining like terms.

= 2pi(12x^2 - 5x -2)

or factor more to simplify the solution.

= 2pi(3x-2)(3x-2+x+3)
= 2pi(3x-2)(4x+1)
