Answer:

Step-by-step explanation:

Use the point-slope formula by the line

y - y_1 = m(x - x_1)      when  x_1 =8   and  y_1 = -2    m :  is the slope (same slope for the line whose equation is 3x + 4y = 15 because are  parallel)

calculate : m

3x + 4y = 15

4y = -3x +15

y = (-3/4)x +15/4     so   m = -3/4

an equation is : y +2 =(-3/4)(x-8)

Answer:

The required equation of line is 3x+4y=16

Step-by-step explanation:

Given : A line that passes through the point (8, -2) and is parallel to the line whose equation is 3x + 4y = 15

To find : What is the equation of a line ?

Solution :

We know that,

When two lines are parallel then their slopes are equal.

The equation of line is 3x + 4y = 15

Convert into slope form y=mx+c,

4y =-3x+ 15

y=\frac{-3x+15}{4}

y=-\frac{3}{4}x+\frac{15}{4}

The slope of the line is m=-\frac{3}{4}

The line passes through (8,-2).

The general point slope form is (y-y_1)=m(x-x_1)

i.e. (y-(-2))=-\frac{3}{4}(x-8)

y+2=-\frac{3}{4}(x-8)

4y+8=-3x+24

3x+4y=16

Therefore, the required equation of line is 3x+4y=16

If (x − 2)^2=49, then x could be ?
Ket [755]
(x - 2)^2=49\\ \\ x^2-4x +4 -49=0\\ \\x^2-4x -45 = 0\\ \\\Delta = b^{2}-4ac =  (-4)^{2}-4*1* (-45)= 16+180=196  \\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{4-\sqrt{196}}{2}=\frac{4-14}{2}=\frac{-10}{2}=-5 \\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{4+\sqrt{196}}{2}=\frac{4+14}{2}=\frac{18}{2}=9 \\ \\Answer : \ x=-5 \ or \ x= 9
