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.

A book sold 33,100 copies in its first month of release. Suppose this represents 7.8% of the number of copies sold to date. How

matrenka [14]

33100 = 7.8% of total
33100 = .078 x total (change from percent to decimal)
33100/.078 = total (divide both sides by decimal)

424358.9 = total

Round to 424,359 copies.

What is the x value and y value of the point of intersection of y = -3x + 10 and y = 2x - 5?

kakasveta [241]

So you can use substitution...which is where you have Y all alone on one side of your equation and then plug it in to the other equation...2x-5=-3x+10 and you.solve for X. So x= 3. Then plug 3 into one of the original equations... Y=2(3)+5. So Y= 11.

A triangle has sides with lengths of 11 miles, 15 miles, and 17 miles. Is it a right triangle?

dybincka [34]

Answer:

Below.

Step-by-step explanation:

If its a right triangle it will obey the Pythagoras theorem.

17^2 = 289

11^2 + 15^2 = 121 + 225 = 346

- so NOT a right triangle.

Simplify 1)5x+3=x+13 2)5/2x-1/X =1/6

Artyom0805 [142]

Step-by-step explanation (Question 1):

Step 1: (Question 1): Subtract x from both sides.

5x+3=x+13

5x+3−x=x+13−x

4x+3=13

Step 2: (Question 1): Subtract 3 from both sides.

4x+3−3=13−3

4x=10

Step 3: (Question 1): Divide both sides by 4.

4x/4 = 10/4

FIRST ANSWER: x = 5/2

Step-by-step explanation (Question 2):

Step 1: (Question 2): Multiply by LCM

15x^2 - 6 = x

Step 2: (Question 2): Solve 15x^2

15x^2 - 6 = x:

x = 2/3

x = -3/5

Step 3: (Question 2): Solve

ANSWER: x=0.666667 or x=−0.6

See Attachment 1 for question 1 steps (FULL)

See Attachment 2 for question 2 steps (FULL)

Answer:

1) x = 5/2

2) x=0.666667 or x=−0.6

Hope this helps.
