Answer: the answers are:6/16=9/x: 9/6=x/16: and 9/x=6/16
Step-by-step explanation:
Answer:
The answer is B. C. and E. love.
C
{-2x + 7y = -5
{-2x - 4y = 6 | · (-1)
{2x + 4y = -6 (+)
----------------------------------
-2x + 2x + 7y + 4y = -5 + (-6)
11y = -11 | : 11
y = -1
{y = -1
{2x + 4y = -6
{2x + 4 · (-1) = -6
{2x - 4 = -6 | + 4
{2x = -2 | : 2
{x = -1
B
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 2x + 3y = 4 into this form
Subtract 2x from both sides
3y = - 2x + 4 ( divide all terms by 3 )
y = - x + ← in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = , hence
y = x + c ← is the partial equation of the perpendicular line
To find c substitute (- 2, 15) into the partial equation
15 = - 3 + c ⇒ c = 15 + 3 = 18
y = x + 18 → B
0.2
it works out to be 0.2 as a decimal and 20% as a percentage.
yes, it is
it will be an obtuse scalene triangle.
