(3,4) and (0, 5) write a linear equation

Mathematics
1 answer:
Nina [5.8K]2 years ago
3 0

Answer:

y=-1/3x+5

Step-by-step explanation:

<u>Slope-intercept form</u>

y=mx+b

m => slope

b => y-intercept

<u>Slope</u>

m=(y2-y1)/(x2-x1)=(5-4)/(0-3)=1/(-3)=-1/3

<u>Y-intercept</u>

y=-1/3x+b

5=-1/3(0)+b

5=b

<u>Final equation</u>

y=-1/3x+5

If 125% of x is 180 ans x is n% of 400. What is the value of n?
Volgvan

Answer:

Value of n is 36.

Step-by-step explanation:

Given:

  • 125% of x is 180
  • Also, x is n% of 400

To Find:

  • Value of n

According to question, we have

125/100 * x = 180

5x/4 = 180

x = 4*180/5

x = 144

Now,

n/100 * 400 = 144 [ x= 144]

4n = 144

n = 36

So, the value of n is 36.

crows are migrating and travel 35 km on a bearing of 047°. Then then fly 15 km of a bearing of 105°. How far , and on wha…
padilas [110]

Answer:

American Crows can be considered partially migratory. That is, some populations migrate, others are resident, and in others only some of the crows migrate. Crows in the southern parts of their range appear to be resident and not migrate. They may make some changes in their use of space at this time, spending more time off the territory to forage and roost. Crows migrate out of the northern most parts of their range. It has been stated that crows migrate out of those areas where the minimum January temperature averages 0 ° F. Certainly crows leave the northern Great Plains in the fall, leaving Saskatchewan and Alberta to winter in the lower Plains states of Nebraska, Kansas, and Oklahoma (Kalmbach, E. R., and S. E. Aldous. 1940. Winter banding of Oklahoma crows. Wilson Bull. 52: 198-206). Crows can be seen crossing the Great Lakes in spring and fall, and these birds undoubtedly are migrating to and from parts of Canada.

Step-by-step explanation:

because  They may make some changes in their use of space at this time, spending more time off the territory to forage and roost. Crows migrate out of the northern most parts of their range. It has been stated that crows migrate out of those areas where the minimum January temperature averages 0 ° F.

Write (-3, -5) (-1, -19) in point slope form
stiv31 [10]

Answer:

(y + 5) = -7(x + 3)

Step-by-step explanation:

Point Slope Form:  (y - y1) = m(x - x1)

<u>Step 1:  Find Slope</u>

m = \frac{y2 - y1}{x2 - x1}

m = \frac{-19 - (-5)}{-1 - (-3)}

m = \frac{-19 + 5}{-1 + 3}

m = \frac{-14}{2}

m = -7

<u>Step 2:  Put into point slope form</u>

Point Slope Form:  (y - y1) = m(x - x1)

(y - (-5)) = -7(x - (-3))

(y + 5) = -7(x + 3)
