What is the equation of this line in standard form

Mathematics
1 answer:
Yuri [45]2 years ago

Line joining (-3, -1) and (1/2, 2)

Point point form for a line is

(c-a)(y-b) = (d-b)(x-a)

(1/2 - - 3)(y - -1) = (2 - -1)(x - -3)

(7/2)(y+1)=3(x+3)

7(y+1)=6(x+3)

7 - 6(3) = 6x - 7y

6x - 7y = -11

Answer: second choice, 6x - 7y = -11

For this you'll have to use the sine ratio.

sin 27 = 34 / x
x = 34 / sin 27
x = 74.89

The answer is 74.89

Answer w/ explanation !!<br><br><br> solve for x
guapka [62]
So you’re gonna do

5x + 2 = 48
-2 -2

5x = 46
and then divide 5 by both sides and you get x = 9.2 (IF YOU GET IT WRONG IM VERY SORRY BECAUSE IM ALSO LEARNING THIS)

You have fallen down a slippery well 10 feet deep. every hour you are able to climb 2 feet out of the well, but then slip down 1
mylen [45]
If every over you climb 2 feet out, but then slip down 1, that means you technically only go up the well 1 ft/per hour. Then, if its 10 ft deep, then it would take you 10 hours.

Solve the inequality 6h−5(h−1)≤7h−11 and write the solution in interval notation. Use improper fractions if necessary.
Kobotan [32]

Answer:

h \geq 2\frac{2}[3}

Step-by-step explanation:

We solve the inequality similarly to how we would solve an equalitu.

6h - 5(h-1) \leq 7h - 11

6h - 5h + 5 \leq 7h - 11

h - 7h \leq -11 - 5/

-6h \leq -16

Multiplying everything by -1

6h \geq 16

Simplifying by 2

3h \geq 8

h \geq \frac{8}{3}

8 divided by 3 is 2 with rest two. So as a improper fraction, the answer is:

h \geq 2\frac{2}[3}

Solve the simultaneous equations <br> 3 x + 2 y = 18 <br> 3 x + y = 12
natulia [17]

Answer:

x=2 , y=6

Step-by-step explanation:

        3 x + 2 y =    18

        3 x +     y =   12

     (-)       (-)         (-)

-------------------------------------------

                     y =    6

                 

3x+6=12

=>3x=12-6

=>3x=6

=>x=6/3

=>x=2
