Hello!

Let's solve this equation for y first.

-10x+y=4

Add 10x to both side.

y=10x+4

Now, let's plug in our x-values to find y.

x: -2, -1, 0, 1, 2

y:-16,-6, 4,14,24

I hope this helps!

x = -2 then y = -16

x = -1 then y = -6

x = 0 then y = 4

x = 1 then y = 14

x = 2 then y = 24

0 is the constant of 4, this functions is a pattern of when ever x increases by 1, you add 10 from y starting from 4, example:

x = 5 then y = 5 * 10 + 4 which is y = 54

y = 54 while x = 5 also satisfies the equation.

Same goes for when ever x decreases by 1, example:

x = -5 then y = -5 * 10 + 4 which is y = -46

y = -46 while x = -5 also satisfies the equation.

This question was the pattern illustrated above.

This is derived from when you take -10x+y=4 and solve for y

Simply add 10x to both sides, and you have already isolated the y variable in the equation y = 10x + 4

You can plug the values in for x and solve for y and recognize the same pattern above.

Can someone please help me with this question?

liq [111]

To get the solution we are looking for we need to point out what we know.
1. We assume that 55 is 100% because its the output value of the task.
2. We assume that the x is the value we are looking for.
3. If 100% = 55 so we can write it down as 100%=55
4. We know that x% = 44 of the output value so we can write it as x%=44.
5. Now we have two simple equations: 1) 100%=55 2) x%=44 where left sides of both of them have the same units and both right sides have the same units so we can do something like that 100%/x%=55/44.
6. Now we just have to solve the simple equation and we will get the answer.
7. Solution for 44 is what percent of 55 100%/x%=55/44 (100/x)*x=(55/44)*x we multiply both sides of the equation by x 100= 1.25*x we divide both sides of the equation by (1.25) to get x 100/1.25=x 80=x now we have: 44 is 80% of 55!

Quick answer = 44 is 80% of 55
Hope this helps! ;D

Z is less than 2 and equal to or less than 8 intersection

insens350 [35]

Less than 2 = z < 2

Less than or equal to 8 = z ≤ 8

z ≤ 8

z < 2

Help ! Please ! If a/2 - b/3=1 , what is 2a+3v in terms of b?

ArbitrLikvidat [17]

A/2-b/3=1 solve for a, add b/3 to both sides

a/2=1+b/3 which is equal to

a/2=(3+b)/3 multiply both sides by 2

a=(6+2b)/3 now you can substitute this into 2a+3b giving you:

2(6+2b)/3 + 3b which is equal to

(12+4b+9b)/3

(13b+12)/3

Valerie has a circular garden. The radius of the garden is 4 feet. She wants to buy edging to outline her circular garden.Which

ss7ja [257]

You'd need to find the distance AROUND the garden, which is also PERIMETER.

To find the perimeter of a circle, you use the following equation:
$2 \pi r$

$2 \pi (4)$ = $8 \pi$

$8 \pi$ = 25.13 ft

I don't know what your answer options are, but chose the option closest to 25.13 ft
