Answer:

see explanation

Step-by-step explanation:

Using the intercept form of the equation of a straight line

\frac{x}{a} + \frac{y}{b} = 1

where a is the x- intercept and b the y- intercept

here a = - 2 and b = 3, hence

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

Multiply through by - 6

3x - 2y = - 6 ← equation in standard form

Substitute x = 2 and y = 6 into the left side of the equation and if equal to the right side then (2, 6) lies on the line

left side = (3 × 2) - 2(6) = 6 - 12 = - 6

Hence line passes through (2, 6)

If the bearing of p from q is 120° , what is the bearing of q from p​
ollegr [7]

Answer:

  300°

Step-by-step explanation:

The reverse bearing is different by 180°. It will be ...

  Q from P = (120° +180°) = 300°

_____

<em>Additional comment</em>

Bearings are always in the range 0 to 360° (not including 360°). That means the reverse bearing will be the original less 180° when the original is 180° or more. It will be the original plus 180° when the original is less than 180° (as here).

Let m=x²-5. which equation is equivalent to (x²-5)²-3x²+15=-2 in term of m?
SpyIntel [72]
The answer would be m^2+3m+2=0 because the first “part” of the equation (x^2-5) is equal to m; in the equation it’s squared so it can be replaced by m^2. next, 3m is the same as 3(x^2+5) which is what you have when you see 3x^2+15. finally, you have to bring the -2 over from the other side so you have positive 2. hope this helps!

1. f(x) = 2x + 6 Evaluate f(2)
fredd [130]
1) f(x)=2x+6
f(2)=2(2)+6
=4+6
=10

2)f(x)=3x
f(a+1)=3(a+1)
=3a+3
3)f(x)=3x-1 and g(x)=5x+3

f(2)=3(2)-1
f(2)=6-1
=5
g(3)=5x+3
=5(3)+32
=15+3
=18


f(2)+f(3)=5+18
=23.
