Answer:

B. 3x + 5y = 1

Step-by-step explanation:

Since, the equation of a line passing through (x_1, y_1) and (x_2, y_2) is,

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Thus, the equation of the line passes through the points (-3,2) and (2,-1) is,

y - 2 =\frac{-1-2}{2+3}(x+3)

y-2 =-\frac{3}{5}(x+3)

5(y - 2) =-3(x +3 )

5y - 10 = -3x - 9

3x + 5y = -9 + 10

3x + 5y = 1

∵ Standard form of a line is ax + by = c, where, a, b and c are any constants,

Hence, the required equation is,

3x + 5y = 1

i.e. OPTION B is correct.

A function graph of a line with two points (-3,2) and (2,-1)

Now we have to find the equation of line passing thorough these points

So let's find slope first using formula:

m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-\left(-1\right)}{-3-2}=\frac{2+1}{-5}=-\frac{3}{5}

Now plug the value of slope m and any point say (2,-1) into point slope formula:

y-y_1=m\left(x-x_1\right)

y-\left(-1\right)=-\frac{3}{5}\left(x-2\right)

Now we simplify it to get equation of the standard form Ax+By=C

y+1=-\frac{3}{5}\left(x-2\right)

5\left(y+1\right)=-3\left(x-2\right)

5y+5=-3x+6

3x+5y+5=+6

3x+5y=+6-5

3x+5y=1

Hence final answer is 3x+5y=1.

A. 5x - 2 = 8<br>b. 4x - 3= 2x + 9<br>C. 6x + 3 = 2x + 8​
Elena L [17]

Answer:

a) x=2

b)x=12

c)x=5/4

Step-by-step explanation:

a)5x-2=8

5x=8+2

5x=10

x=2

b)4x-3=2x+9

4x-2x=9+3

2x=12

x=6

c)6x+3=2x+8

6x-2x=8-3

4x=5

x=5/4

Proof:

a)5x-2=8

5(2)-2=8

10-2=8

8=8

b)4x-3=2x+9

4(12)-3=2(12)+9

48-3=24+9

45=45

c)6x+3=2x+8

6(5/4)+3=2(5/4)+8

30/4+3=10/4+8

15/2+3=5/2+8

10.5=10.5

Hope this helps ;) ❤❤❤

Explain how to determine the zeros of f(x)= (x+3)(x-2)(x-6)
Deffense [45]

Answer:

The zeros of f(x)  are -3, 2 , 6

Step-by-step explanation:

f(x) is a polynomial of degree 3.

If the polynomial is not factorized we will either factorize to find the zero or use trial and error method.

Since the f(x) in the question is in the factorized form. we will have to equate each factor to zero.

f(x) = (x+3)(x-2)(x-6)

x + 3 = 0 => x = -3

x - 2 = 0 =>  x = 2

x - 6 = 0 => x = 6
