slope intercept form

y -y1 = m(x-x1)

y-3 =1/4 (x-4)

distribute

y-3 =1/4 x-1

stand form of a line is Ax +by =c

so subtract 1/4 x from each side

y -3 -1/4 x =-1

add 3 to each side

y-1/4 x =2

-1/4 x +y =2

I would multiply by -4 on both sides to make the 1st term positive and get rid of the fraction

x -4y = -8


Find the slope of the line that crosses through the points (-3, -4) and (2, -3).

slope = (y2-y1)/(x2-x1)

m = (-3--4)/(2--3)

m = (-3+4)/(2+3)

m =(1/5)

m=1/5

Answer:

≈ 3.6 x 10^1

Step-by-step explanation:

= (6.05 x 3.05) x 10^(5+4) / (4.27 x 1.2) x 10^(4+4)

= 18.4525 x 10^9 / 5.124 x 10^8

= (18.4525 / 5.124) x 10^(9-8)

≈ 3.6 x 10^1

The square of a negative number is twenty-eight more than three times the negative number. Find the number.
MAXImum [283]
The number is x

it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero

x-7=0
x=7
this is not the answer because we were told the number was negative


x+4=0
x=-4
correct

the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check


the number is -4

Answer:

The correct option is 3.

Step-by-step explanation:

It is given that the quantities of blue and green paints used for each mix and connected them using a line segment, as shown in the graph below:

The line have two end points A(1,2) and B(9,14).

Domain is the set of inputs. In a graph all the values of x for which the graph is defined, are domain of the function.

The line is defined from x=1 to x=9. So, the domain of the function lies between 1 to 9 (inclusive).

1\leq x\leq 9

Therefore, option 3 is correct.

Line AC and line DB intersect at point P. Solve for angle BPQ.
taurus [48]

Answer:

Angle BPQ = 64°

Step-by-step explanation:

4x + 12 +2x = 90

6x + 12 = 90

     - 12    -12

6x = 78

x = 13°

BPQ = ((4(13) + 12)°

           (52 + 12)°

            64°
