The value for b in y=mx+b,directly from the table w/out drawing a graph or going any calculations ?

Answers

the value of b is the y intercept or when the line crosses the y axis
this only happens when the value of x=0
so just look for the ordered pair in the table with x=0 and y=b
so if you had a table and saw
(0,3)
(x,y)
so the point where x=0 is at point (0,3) y=3
therefor b=3

basically look for the matching y value for when x=0

The b value in y=mx+b is how many units up or down the y-axis you go from the origin. For example, if y=mx+2, you would move 2 units up, or if it was y=mx-3 you would move 3 units down.

Y = 4x+1 y=x^2 + 2x - 2 A.6,2 B. 2,6 C. -6,2 D. -6,-2

Answers

Answer:

The solution is (3,13) and (-1,-3). So none of the mentioned options is correct.

Step-by-step explanation:

Given that

$y = 4x + 1 (i)$

$y = x^2 + 2x -2 (ii)$

Now, by susbstituting the value of 'y' from equation i to equation ii, we get

$4x+1=x^2 + 2x -2$

$0=x^2 + 2x -2-4x-1$

$0=x^2 + (2x -4x) +(-2-1)$

$0=x^2 + (-2x) +(-3)$

$0=x^2 -2x -3$

$x^2 -2x -3 = 0 (iii)$

Now by factorization, equation iii can be written as

$x^2 -3x +x -3 = 0$

$x(x -3) + 1(x -3) = 0$

$(x -3)(x +1) = 0$

x = 3 and x = -1

By putting the values of x in equation i, we get

y = 4(3) + 1

y = 12 +1

y = 13

and

y = 4(-1) + 1

y = -4 +1

y = -3

Therefore, the solution is (3,13) and (-1,-3). So none of the mentioned options is correct.

Which fractions are equivalent to -3/8? A. -6/16, B. 12/32, C. -3/8, D. 9/-24

Answers

The answer is 12/32 because its both an even number and my 2nd grade teacher said even numbers are equivalent,

the answer is A.-6/16 and C.-3/8 because both the numerator and denominator need to be multiplied the same number.
