zysi [14]

Answer:

41

Step-by-step explanation:

The number 1 is in the ones place. 1x4=4, so 4 is in the tens place. If you reverse 41, you get 14. 41+14=55.

Write an equation of the line that passes through (3,2), and is perpendicular to the line
frutty [35]

Step-by-step explanation:

step 1. perpendicular lines have negative reciprocal slopes

step 2. perpendicular to m = 1/3 is the slope m = -3/1 or m = -3

step 3. a line through (3, 2) with m = -3 is y - 2 = -3(x - 3)

step 4. y - 2 = -3x + 9

step 5. y = -3x + 11.

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, the
san4es73 [151]

Answer:

We get value of the value of b = 5

Step-by-step explanation:

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, then m=m equals negative StartFraction 1 Over 6 EndFraction.. What is the value of b?

We have slope m: m=-\frac{1}{6}

We need to find value of b (y-intercept)

Using the point A(-6,6) and slope m=-\frac{1}{6} we can find b.

Using slope-intercept form, putting values of m and x and y we get the value of b:

y=mx+b\\6=-\frac{1}{6}(-6)+b\\6=1+b\\b=6-1\\b=5

So, we get value of the value of b = 5
