2x-3=x+4
x=7
You first do 7x-5x, then you move -3 to the other side, and you move the x to the left side, so it makes it 2x-x=3+4 so x=7

Answer:

Slope (m) = \frac{y}{x} = \frac{3}{1} =3

Step-by-step explanation:

Slope (m) = \frac{y}{x} = \frac{3}{1} =3

0 = arctan(\frac{y}{x}) + 180^o = 251.56505117708^o

X = -4 – -2 = -2

Y = 4 – 10 = -6

Distance (d) = \sqrt{x^2+y^2}=\sqrt{40} = 6.3245553203368

Equation of the line:

y = 3x + 16

When x=0, y = 16

When y=0, x = -5.3333333333333

WILL GIVE BRAINEST <br>if f(x)=2x-5 and g(x)=x2.....
Ymorist [56]
Note that the notation (f+g)(x) is just another way of writing f(x)+g(x). Here, we're simply taking the expression for f(x) and adding the expression for g(x) to it. Together, we have:

f(x)=2x-5\\g(x)=x^2-4x-8

Which means that

(f+g)(x)=f(x)+g(x)=(2x-5)+(x^2-4x-8)

And from there, it's just a matter of combining like terms to simplify.
