--- * ? = ---
9 15

We want to find the fraction represented by " ? " above.

We want to isolate the " ? " so mult both sides by the inverse of (2/9):

(9/2)(2/9) f = (3/15)(9/2) = 27/30 = 9/10

so the unknown fraction is 9/10.

Check your work: Is (2/9)(9/10) = 3/15? Is 1/5 = 1/5? YES.

Solve (2x+3) (x+4)= 1

Digiron [165]

To solve, simply layout an equation.

(2x+3)(x+4)=1

Step 1: Simplify both sides of the equation.

2x2+11x+12=1

Step 2: Subtract 1 from both sides.

2x2+11x+12−1=1−1

2x2+11x+11=0

Step 3: Use quadratic formula with a=2, b=11, c=11.

x=-b±√b^2-4ac/2a

So, the answer for this problem is:

x=-11/4+1/4√33 or -11/4+-1/4√33

What is the equation of the line that passes through (-2, 2) and (1, -4)?

poizon [28]

Answer:

y = - 2x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ = (- 2, 2) and (x₂, y₂ ) = (1, - 4)

m = $\frac{-4-2}{1+2}$ = $\frac{-6}{3}$ = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 2), then

2 = 4 + c ⇒ c = 2 - 4 = - 2

y = - 2x - 2 ← equation of line
