You start by finding two points on the line. In this case, (-4,1) and (-2,2) will do.

To get from (-4,1) to (-2,2), you need to go “up 1, right 2” which gives you a slope of m = 1/2

Next you need the b-value, which comes from the y-intercept of (0,3). The b-value is 3.

Putting the slope and b-value into y=mx+b, you have y = 1/2 x + 3.

Which steps can be used to solve for the value of 'y'? 2/3(y+57)=178

bagirrra123 [75]

2 / 3 ( y + 57 ) = 178

2( y + 57 ) / 3 = 178

2*y + 2 * 57 / 3 = 178

2y + 114 / 3 = 178

3*(2 y + 114 ) / 3 * ( 178)

2 y + 114 = 534

2y = 534 - 114

2 y = 420

y = 420 / 2

y = 210

hope this helps!

Whats the squareroot of 98

Taya2010 [7]

Answer: 7√2

Step-by-step explanation: To simplify a square root where the number inside the radical is not a perfect square like the square root of 98, we start by making a factor tree for the number inside.

98 factors as 2 · 49 and if you know your perfect squares,

you should be able to recognize 49 as 7 · 7.

What we are looking for in our factor tree

are pairs of factors that are the same.

If a factor pairs up, it will come out of the radical.

If a factor does not pair up, then it stays inside the radical.

So here, since our 7's pair up, a 7 will come out of the radical.

Since the 2 does not pair up, it stays inside the radical.

So our answer is 7√2.

What is the value of 2x^4 5x when x=6(please show work thank you)!

Katyanochek1 [597]

So when you plug in x, you get 2(6^4)*5(6). So simplifying the equation, we get 2(36^2)(30). Getting the square of 36, 2(1296)(30) so we can change it to 60(1296) which is 77,760
