Answer:

y=3x+1

Step-by-step explanation:

Your equation should start off as y=mx+b. You must solve for m and b, although they already give you m and b. m is the slope, which here is 3 and your y is 1. Making your equation, y=3x+1.

Pls pls answer this asap no wrong answers pls

klemol [59]

Answer:

20, increased, Bianca

Step-by-step explanation:

First one:

He is shown to have travelled 20km in 1 hour, so that's 20km/h.

Second:

The gradient is how steep the curve is, the steeper the faster the person is travelling. Due to the fact Bianca's curve becomes steeper, it shows she is travelling faster. Therefore, her running speed increases.

Third:

Bianca's line hits 50km before Alberto, so therefore she finished first.

Let me know if this makes sense, hope it helped! :D

Completely simplify the rational expression LaTeX: \frac{7x}{3y} + \frac{12x}{9y}

irina [24]

Answer:

$\frac{11x}{3y}$

Step-by-step explanation:

$\frac{7x}{3y} + \frac{12x}{9y}$

To add the two fractions, you need a common denominator. In this case, the lowest common denominator (LCD) is 9y. That's because 9y is divisible by both 3y and 9y.

The first fraction must be changed so that its denominator is 9y. Do this by multiplying both numerator and denominator by 3.

$\frac{7x}{3y}\cdot\frac{3}{3}+\frac{21x}{9y}=\frac{21x}{9y}+\frac{12x}{9y}\\=\frac{21x+12x}{9y}\\=\frac{33x}{9y}$

Finally, this answer can be simplified ("reduced") by dividing both numerator and denominator by 3, their greatest common factor.
