Answer:


Answer:


The equation of line passing through (−2,3) is y−3=−3/2(x+2)

Explanation:


The slope of the line 3x+2y=10or2y=−3x+10ory=−32x+5 is m=−3/2[y=mx+c].


Parallel lines have equal slopes.


The equation of line passing through x1,y1 is y−y1=m(x−x1)


So the equation of line passing through (−2,3) is y−3=−3/2(x+2)[Ans]

Answer:

Y=-5/6x +2.74

Step-by-step explanation:

The reason that is correct is because a line that has a slope of -5/6 that also passes through the point (8,-4) would have to cross the Y axis at 2.75.

If f(x) = 3x-2 and g(x) = 2x + 1 find (f-g)(x)
Marat540 [252]

Answer:

x-3

Step-by-step explanation:

f(x) = 3x-2

g(x) = 2x + 1

(f-g)(x) = 3x-2 - (2x+1)

Distribute the minus sign

          =3x-2-2x-1

Combine like terms

        = 3x-2x-2-1

        =x-3

One lap around a parking lot is 3/10 mile.this represents 15% of the total distance Gregory ran.what is the total distance in mi
sattari [20]
Given:

One lap around a parking lot = 3/10 mile
3/10 mile is 15% of the total distance Gregory ran.

To determine the total distance (in mile) that Gregory ran, we refer to the given percentage:

3/10 mile / 0.15 = 2 miles

The total distance that Gregory ran is 2 miles. <span />

Please Help!!!!!! Use what you've learned today about the sum of the interior angles of triangles and quadrilaterals to determin
sveta [45]

Answer:

m = 116

x = 24

y = 76

z = 40

Step-by-step explanation:

For startes the interior angles of triangles always add up to 180 degrees.

That means....

73 + 83 + x = 180

z + m + x = 180

z + y + 64 = 180

Another important fact is that two angles that are intersected by a line in the case 64 and m always add up to 180 degrees.

So m + 64 = 180

Let's start with 73 + 83 + x = 180

If you add 73 and 83 you get 156

x + 156 = 180 then subtract 156 from both sides and

x = 24

Then use m + 64 = 180 subtract 64 from both sides and

m = 116

z + m + x = 180 become

z + 116 + 24 = 180

Add 116 and 24 and you get 140

z + 140 = 180 subtract 140 from both sides and

z = 40

Check to make sure m + x + z = 180

24 + 40 + 116 = 180

z + y + 64 = 180 becomes

y + 40 + 64 = 180

40 + 64 = 104 so

y + 104 = 180 subtract 104 from both sides and

y = 76

Congratulations you have found all of the angles!

Show that 5/6 - 3/4 = 1/12
spayn [35]
We have to check if LHS = RHS
First solve LHS
\frac{5}{6}- \frac{3}{4} = \frac{5*2}{6*2}- \frac{3*3}{4*3} = \frac{10}{12}- \frac{9}{12}= \frac{1}{12}&#10;So LHS is equal to RHS.
