Answer:

B. 0

Step-by-step explanation:

-49/100 + 10/21

They are both about half

Therefore, since one is negative and the other is a positive they would equal about .02 which the closest number out of the 4 answers would be B. 0

Answer:

0 (b)

Step-by-step explanation:

So we're estimating in this one.

we can round -49/100 to -50/100 and 10/21 to 10/20

Then we can get a common denominator

10/20 will become 50/100

-50/100 + 50/100 = 0

So your answer is b.

Nter the equation of the line in slope-intercept form. Slope is 6, and (1, 3)

kupik [55]

Answer:

The equation in the slope-intercept form will be:

$y=6x-3$

Step-by-step explanation:

Given

slope = m = 6

point = (1, 3)

As we know that the equation of a line in point-slope form is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = 6 and point = (1, 3)

$y-3=6\left(x-1\right)$

Writing the equation in slope-intercept form

$y=mx+b$

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

$y-3=6\left(x-1\right)$

add 3 to both sides

$y-3+3=6\left(x-1\right)+3$

$y=6x-3$

Therefore, the equation in the slope-intercept form will be:

$y=6x-3$
