Which ordered pair represents the y-intercept of the graph of the equation y = -3x - 9?

german

The y-intercept is the point where the graph crosses the y-axis. It is found by setting x=0. For your equation, that makes the x-term vanish and only the constant remains. The ordered pair is ...
(x, y) = (0, -9)

A freight train travels 260 km in the same time a passenger train travels 320 km. If the passenger train averages 15km/hour fast

JulsSmile [24]

Time = t

vf t = 260 
vp t = 320 
so 

260/vf = 320/(vf+15) 

320 vf = 260 vf +260(15) 
60 vf = 390 
3 vf = 39 
vf = 13 km/hour

What is the GCF of the terms of 3x⁴-9x²-12x?

Alexxx [7]

Answer: The GCF of the terms of $3x^4-9x^2-12x$ is $3x$ .

Step-by-step explanation:

We need to find: GCF(Greatest common factor) of the terms of $3x^4-9x^2-12x$ .

The greatest common factor(GCF) is the greatest factor that divides two expressions.

Here,

$3x^4=3\times x \times x \times x \times x \\9x^2=3\times 3 \times x \times x\\12x=3\times 2 \times 2 \times x$

The greatest common factor of $3x^4-9x^2-12x$ = $3x$

Hence, the GCF of the terms of $3x^4-9x^2-12x$ is $3x$ .

Please help me out!!!!!!

mestny [16]

Answer:

Since we knew that the triangles are similar, we have:

19/38 = (x + 7)/(3x + 3)

=> 1/2 = (x + 7)/(3x + 3)

=> 3x + 3 = (x + 7) . 2

=> 3x + 3 = 2x + 14

=> 3x - 2x = 14 - 3

=> x = 11
