Answer:

A, is the answer.

Step-by-step explanation:

If you take two points and then find the slope between them you'll find that it is 1.5.

You could also make a T-chart or plug in the x coordinates into each possible equation and see which one matches the corresponding y coordinate.

It’s not 0.615 , or 0.75 or the one shown in the picture

Dafna1 [17]

$2.40714$

1) Let's evaluate that expression, given that a=4.9, b=-7, and c=-0.5

$\begin{gathered} a^3\div b^2+c^3 \\ (4.9)^3\div(-7)^2+(-0.5)^3= \\ \frac{4.9^3}{\left(-7\right)^2+\left(-0.5\right)^3} \\ \\ \frac{4.9^3}{48.875} \\ \\ \frac{117.649}{48.875} \\ \\ 2.40714 \end{gathered}$

Note that we have rewritten it as a fraction so that we can easily operate. Also, we have applied here the PEMDAS order of operations, prioritizing the exponents.

In response to very high demand, a new bike has been marked up by 25% and is now selling for 210.00. how much was the bike befor

harina [27]

Call the price of the bike before mark up 'x', then we have:

x + 0.25x = 210
1.25x = 210
x = 168

Therefore, the bike cost $168 before 25% price increase.

Find the equation of the line, where P is a point on the graph of the line.<br><br> m=2/3 , P(3,5)

Liula [17]

Answer:

The answer is

$y = \frac{2}{3} x + 3$

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To write an equation of a line given a point and slope we have

y - y1 = m( x - x1)

where (x1 , y1 ) is the point and m is the slope

Equation of the line using point P(3 , 5) and m = 2/3 is

$y - 5 = \frac{2}{3} (x - 3)$

$y - 5 = \frac{2}{3} x - 2$

$y = \frac{2}{3} x + 5 - 2$

We have the final answer as

$y = \frac{2}{3} x + 3$

Hope this helps you
